Tracking the Jio effect

Today OpenSignal released its latest State of LTE report, comparing 4G speeds and 4G availability in 75 countries around the globe. While we see some interesting overall LTE trends, there is one country that stood out in our data. India shot up our 4G availability charts since we published our November State of LTE report, claiming a spot among the top 20 countries in the world.

Something happened in India that made LTE signals much more widely available to the mobile-data consuming populace, and we have a good idea of what that something was: Reliance Jio’s commercial debut. The operator launched its nationwide LTE network in September 2016, and in the ensuing months Jio has been on a rampage, signing up 100 million subscribers drawn in by its inexpensive and virtually unlimited 4G data plans. Jio’s launch did more than just create more 4G subscribers, it boosted India’s overall 4G availability from 72% to 82% in the six months between our State of LTE reports.

Jio isn’t the only 4G operator in India, of course, but OpenSignal’s recently published India report clearly shows a big gap between it and India’s other national 4G providers when it comes to providing a consistent LTE signal. OpenSignal’s crowdsourced users were able to find an LTE signal on Airtel, Idea and Vodafone 60% of the time or less. Meanwhile our testers were able to connect to Jio’s 4G network more than 90% of the time. That number may seem quite high, but it relates to Jio’s unique situation as a 4G-only operator in India. It’s deployed its LTE infrastructure as an umbrella network, not as an overlay, as it has no 2G or 3G services to fall back on.

But it’s not just Jio’s new network that’s boosting India’s overall 4G availability score. Jio’s enormous subscriber growth — much of it at the expense of its competitors — is amplifying Jio’s impact. Not only does Jio have exceptionally accessible 4G networks, according to our measurements, but Jio’s fast growing share of the Indian 4G market means its customers are having an increasingly bigger say in determining India’s overall results. In India we have one of those rare instances where a single operator is having a dramatic effect on the mobile market in a short space of time.

There is a downside to Jio’s enormously fast ramp up, however. Jio’s emergence has not only caused overall LTE availability in India to rise, but overall 4G speeds to fall. India now sits one above last place in our 75-nation 4G speed analysis, averaging LTE download speeds of 5.2 Mbps, which is well short of the global average of 16.4 Mbps and only marginally better than the global average 3G connection of 4.4 Mbps. In our India report we measured the slowest LTE speeds on Jio’s LTE network, which is likely due to the enormous strain its success is placing on its network. Anytime you add 100 million users to a network and grant them unfettered access to data, speeds are bound to suffer.

The sun shines on Sunrise’s 4G performance

Having just wrapped up the latest installment of OpenSignal’s Italy report, why not hop over the border to take a look at Italy’s northern neighbor? OpenSignal is pleased to announce the latest country to join our coverage list: Switzerland. Examining millions of datapoints, we compared the mobile experience seen by OpenSignal users across the Swiss Confederation.

In general, Salt, Sunrise Communications and Swisscom all performed well in our tests. Our measurements showed fast speeds, a high level of LTE accessibility and very good network response rates from all three operators. Based on our tests, few Swiss subscribers are suffering from low-quality mobile data connections.

Sunrise, however, did stand out in a few categories. It excelled in 4G speed, averaging download connections of 35.3 Mbps in our tests – results that are more than double the global 4G average of 17.4 Mbps and more than 12 Mbps faster than those of its two rivals. Those 4G scores propelled Sunrise to the top of our rankings for overall speed, which measures the typical download speed experienced by our users across an operator’s mobile data networks.

Swisscom took home plenty of awards as well. It tied with Sunrise for 4G availability, which tracks the proportion of time users have access to an LTE signal. And it grabbed both of OpenSignal’s prizes for latency, indicating highly responsive networks.

The full results in our State of Mobile Networks: Switzerland report. And if you’re a Swiss smartphone user who wants to test your operator’s network yourself as well as contribute data to our future reports, we encourage you to download the OpenSignal app (available on iOSand Android) or our new Meteor app.

Vodafone and TIM keep their 4G lead over the new Wind Tre

Wind and 3’s merger may have created the largest operator in Italy on paper, but it’s clear the new Wind Tre has some work to do before its network catches up. In our third State of Mobile Networks: Italy report, we took a final look at the speeds and signal availability of Wind and 3’s mobile networks before they’re merged under a single Wind Tre umbrella. While we did see some improvements in both Wind and 3’s performance, they’re both still well behind Vodafone and Telecom Italia Mobile in nearly every metric we cover.

The biggest standout in this report was Vodafone, which won the majority of OpenSignal’s awards in speed and availability. Vodafone’s 4G speeds were particularly noteworthy as it averaged LTE downloads of nearly 40 Mbps nationally and even exceeded 50 Mbps in Milan. Meanwhile TIM distinguished itself in our latency tests, an indication of highly responsive mobile data networks.

In availability, though, all four operators had favorable news. We saw LTE availability jump across the board, meaning our users were able to connect to a 4G signal much more often across Italy. Our testers were able to find an LTE connection on Vodafone and TIM’s networks more than 70% of the time. Though Wind and TIM also saw improvements in their availability scores, they have a long way to go before they close the gap with their competitors. OpenSignal users only had access to Wind and 3’s 4G connections half the time.

It will be interesting to see how these rankings change in the next year as Wind and 3 become a single operator not just in name, but also in network capabilities. By merging their spectrum holdings and combining their 3G and 4G footprints, they’ll likely be able to offer Wind Tre customers much faster speeds as well as greater network reach. Whether they can close in on Vodafone and TIM’s sizable lead, though, remains to be seen.

UK: How fast and how accessible is 4G in your city?

If you had one guess what the fastest 4G city in the U.K. might be, would that guess be Stoke-on-Trent? That’s right, Stoke is more than just the heart of England’s pottery industry. According to OpenSignal’s measurements, Stoke also lays claims to the fastest 4G speeds of any big city in Great Britain.

Following up on our State of Mobile Networks: UK report, OpenSignal and consumer advocate Which? decided to take a closer look at how the top 20 urban areas in Great Britain fared in 4G speed and 4G availability between Dec. 1 and Feb. 28. You’ll find both charts below, though some of the numbers may surprise you. Instead of major metropoles like London, Manchester and Birmingham dominating the rankings, we see many of the lesser-known lights of urban England at the top of our lists.


The aforementioned Stoke led our 4G speed rankings, averaging LTE download speeds of 26.4 Mbps in our measurements. That’s nearly 2 Mbps faster than the next fastest city Coventry and 3.5 Mbps faster than the average 4G download speed for all of Great Britain. Only half of the 20 cities we examined wound up above that national speed average of 22.9 Mbps. Most notably London was below it with average LTE connections of 20.5 Mbps. Last place, however, went to Brighton and Hove.


Middlesbrough topped our 4G availability rankings. Our smartphone users there were able to latch onto an LTE connection 82.7% of the time, an impressive number considering the average 4G availability across England, Scotland and Wales was just 65.1%. In fact, all 20 cities exceeded that mark. The city with the least accessible 4G service was Bournemouth, with an LTE availability score of 67.5%. But overall 4G signals are far more consistently available in the cities than in the countryside as you would expect.

The Meteoric rise of a down-to-earth app

Why another speed test?

Among other features, our flagship app OpenSignal tests the speed of your internet connection. So why create another app to do that? Well, we don’t really see Meteor just as a beautiful speed test (though we agree it is!). When we came up with the concept for Meteor, what we had in mind were the connection needs of internet users who don’t necessarily know their megabits from their megabytes, but want to understand how much (or how little) they can do with their current speed. And this is where the idea of looking at the way specific apps will work at a given speed came into play.

From testing speed to grading apps

A series of user interviews confirmed our hypothesis: there was definitely interest for an app that would go beyond testing speed, to measuring what it was good for. How did those megabits and milliseconds translate in terms of video streaming, web browsing or gaming? What was the impact of download speed, upload speed and latency in the way apps worked? How Meteor addresses these questions — by grading your speed results and the apps’ performance you can expect from them —  is the outcome of several rounds of interviews, design iterations, copy writing and beta testing.

Some out-of-this-world results

The impact of Meteor has by far exceeded our expectations. Covered by press outlets all over the world — from Chile to China, from India to Italy —, it’s been hailed as “the prettiest internet speed test app” and “a decent alternative to”. The feedback we’re getting from users is even more exhilarating: “amazing and passionately crafted”, “works flawlessly”, “a lot more accurate than all the other testing apps”, “extremely informative and thorough. I wish I could give it more stars”. If you are of the opinion that numbers speak louder than words, we can offer you a few of those too!

Meteor’s first two months in numbers

An updated Meteor touches down!

We still have a lot planned for Meteor in the upcoming months and as a matter of fact, the latest release is hitting the app store as I write this, with some rather cool new features in tow. What’s new in Meteor 1.02, I hear you ask?

  • New apps to choose from, based on our users’ feedback, including Netflix, Snapchat and Twitch.
  • New awesome way of selecting apps you want to test for
  • Added Kbps units, by popular demand
  • Better performance in History tab
  • Sharing options for your beautiful speed test results
  • Additional settings for increased control of the app
  • Neater display of app performance details
  • Other UI improvements (we’re keeping our designer as busy as ever!)
  • Last but not least…drumroll…Grade Your App Experience — a novel feature to contribute your personal app gradings to Meteor. Because we believe there’s no better judge than you of the quality of experience you’re getting from your internet connection!

What’s on the horizon…

This is the story of Meteor so far — an upward trajectory that wouldn’t have been possible without the feedback and support from our users, beta-testers and interviewees. And it’s only the beginning, with some exciting developments yet to come. The Grade Your App Experience feature will bring valuable Quality of Experience feedback; we’ll use it to train Meteor’s model to make its apps’ gradings more and more accurate. An iOS version of Meteor is also cooking — get notified when it’s ready to be sure not to miss it, the sign up form is below! And watch this space for more…

UK’s 4G signal reach jumps upwards

In our last few U.K. reports we reported what a lot of smartphone users already knew: 4G signals in the U.K. were hard to come by. But that’s a refrain we aren’t repeating in our latest State of Mobile Networks: UK report.

In six months U.K. operators have taken some big strides in improving their LTE availability scores, which is a measure of the proportion of time smartphone subscribers have access to a 4G signal. All four operators saw a 5% or better jump in this metric, and for the first time we see an operator with a 4G availability score higher than 70%. That operator is EE, but Vodafone and O2 are close on its heels. Our testers were able to find an LTE signal on their respective networks 69% and 68% of the time. Even 3 saw a big 6% jump in availability between this report and the last, but it’s still far behind the other operators in our rankings.

The U.K. still doesn’t have the extensive 4G reach we see in many countries in Northern Europe, East Asia and North America, but if it keeps improving at this pace, it could very well catch up soon.

OpenSignal begins full coverage of India

Over the last year, OpenSignal has published a few blog posts on some of our more interesting findings in the Indian mobile scene, but our plan has always been to do a more thorough analysis of one of the largest and most complex telecom markets in the world. Well, today we’ve accomplished that goal. We’re proud to debut our State of Mobile Networks: India report, the first of what will be many detailed looks at the mobile data experience in the subcontinent.

India proved to be a very challenging market to analyze because it’s so fractured. Nearly a dozen operators offer service in India, but not all of them compete head to head in every region. India is divided into 22 telecom circles, and each operator runs networks in a different set of circles. Normally that would make any national comparison between operators impossible, but in recent years a handful of operators have emerged as national players in either 3G or 4G services, and it’s those operators on which OpenSignal has focused its national analysis. We didn’t stop at a national comparison though. We selected four significant telecom circles and conducted a regional LTE analysis of each one. You can read our detailed analysis and see our interactive charts in the full report here.

Our report debuts at a rather controversial time for the Indian telecom sector. The launch of Reliance Jio and its inexpensive and virtually unlimited data plans have set off a new wave of competition and a war of words among India’s top operators. Reports such as this one are therefore drawing a lot of attention and generating a lot of arguments. As our report goes live, we felt we needed to be transparent about our methodology and to explain how we’ve used it to measure the mobile experience of smartphone users in countries across the world.

First, OpenSignal uses crowdsourcing to collect data. Users download our app, which allows them to perform speed and signal tests from their smartphones both actively and in the background. All of that data is sent to OpenSignal stripped of any personal information (we protect our users’ anonymity) where it’s collected in our databases and used as the jumping off point for our reports and detailed online and in-app coverage maps. For this report alone we gathered more than 1.3 billion measurements collected by 93,464 smartphone users across India.

In short, we have access to a lot of data. But collecting a huge volume of data isn’t everything. Painting an accurate picture of the mobile data experience in a country also depends on how you interpret that data. OpenSignal has adopted a methodology for collecting and analyzing data that provides a holistic look at mobile data services and best represents what the typical consumer sees on a day-to-day basis.

One example of this approach is how we aggregate our speed test results. In India, there is a small subset of users that conduct a massive volume of speed tests (thousands a month compared to a handful for the typical user). Those tests are often run when the network is at optimal performance. If our methodology were to count each speed test equally, we would have a small handful of users skewing our results, often in favor of a particular operator. OpenSignal’s methodology avoids that issue by averaging the speed tests of each user, and then counting each average equally. That ultimately fits well with our philosophy. We want to examine the experience of all subscribers on a particular operator, not the experience of a few very active testers.

Another example is how we treat dual-SIM data, which is especially important in India where many people subscribe to more than one operator’s service. The problem here is assigning the proper test to the proper operator, since the same phone is connecting to different services. It’s a problem that OpenSignal has solved through the careful parsing of our data. We’re able to identify the individual network our users connect to whenever conducting a test and then assign that measurement to the correct operator.

If you want to read more about how we collect and analyze our data, we encourage you to read the methodology section of our website. And be sure and let us know your thoughts on our India report in the comments section below.

Whose customers are using Wifi the most in the US?

Though we may be in the era of fast 4G connections, Wifi still plays a significant role in our mobile connectivity. We spend a lot of time connected to Wifi networks at home, work and at public hotspots. But just how much time exactly do we spend on Wifi? I decided to find out by digging down into OpenSignal’s U.S. data.

I looked at our connection data for the four U.S. national operators in the first quarter of 2017 and found that our smartphone users spent roughly half of their time connected to Wifi versus cellular networks. But there were some differences between the subscribers of the different operators, as you can see in the chart below.

Verizon subscribers spent the highest percentage time connected to Wifi at 54%, followed by AT&T (52%) and Sprint (51%), but the big standout in our data was T-Mobile. Our users were only connected to Wifi 43% of the time, indicating that the typical T-Mobile subscriber was spending far more time connected to his or her operator’s cellular networks than a typical subscriber on the other three operators.

So how do we interpret this data? It’s tempting to view these Wifi patterns through the lens of the operators’ data plans. T-Mobile and Sprint have been selling unlimited data plans for some time now, while AT&T and Verizon only recently reintroduced unlimited as an option for new subscribers. Customers that don’t have to worry about data overage charges have less incentive to seek out free or cheap Wifi connections. It’s perhaps no coincidence that the two operators with lowest time-on-Wifi scores are the ones with customer most accustomed to not counting the megabytes they consume. But that’s also a rather simplistic explanation. There are lots of reasons why one operator’s customers could be finding Wifi signals more than others.

Some operators, for instance AT&T, have built carrier Wifi networks, automatically connecting customers to hotspots whenever they’re in range. The type of customers each operator caters to could also have a big impact. Business professionals, for example, often log into workplace networks as soon as they clear their office lobbies. They’re also more likely to pay for access to dedicated Wifi access at hotels, airports and convention centers.

I should note that time spent on Wifi is not the same thing as the amount of data consumed on Wifi. Just because your phone happens to be connected to a Wifi router doesn’t mean it’s actively surfing the mobile internet. That’s one of the main reasons that Wifi connections make up such a large share of all smartphone connections. Our smartphones spend a lot of time at home and in the office passively connected to our local networks. But that passive connectivity can tell us some interesting things as well. If an operator’s customers skew young, their time on Wifi numbers will skew low. Younger folks tend to go out more, leaving the familiar embrace of their home networks. Old fogies like me, on the other hand, barely leave the house. I’m willing to bet my time on Wifi score is in the 80% range.

OpenSignal’s forthcoming “State of Mobile Networks: India” report and recent references to OpenSignal data

OpenSignal will soon publish its inaugural “State of Mobile Networks: India” report which will provide the most definitive analysis of mobile experience OpenSignal has ever carried out. In this report, we’ll compare the typical speeds, latencies and 4G availability on each of the major operators’ networks based on billions of data points collected from users of the OpenSignal mobile app. This report will be based on our most recently available data and contain both a nationwide and regional analysis of the mobile experience recorded in India.

We note that there have been recent articles indicating that OpenSignal has taken a formal position on the Indian telecoms market and we would like to take this opportunity to clarify that this is not the case. To date, we have published an analysis of LTE speed and availability in a set of India’s largest cities but this does not include an analysis of individual operators. In addition, the OpenSignal mobile app contains some average statistics on measurements in India, but these are localized, indicative results sampled over a longer period of time of 9 months and therefore cannot be considered a definitive, nationwide analysis representing the most current state of affairs. This will only come through OpenSignal’s forthcoming “State of Mobile Networks: India” report.

The Indian telecoms market is in a highly dynamic state with competing reports on how the different service providers offerings stack up so the timing is perfectly poised for OpenSignal to release its first report. In the meantime we advise the public to avoid any misleading reports and stay tuned to official OpenSignal channels to be notified when our report is released.

LTE spreads its wings in Mexico

It’s been a busy six months for Mexico’s mobile operators. Since we published our last State of Mobile Networks report in October, AT&T Mexico, Movistar and Telcel have all been expanding the reach of their LTE networks, and not by insignificant amounts. In our new report, we saw a 4% increase in LTE availability across the board, meaning Mexico’s 4G users now have more access to LTE signals than ever before.

Though we saw improvements from all three operators in our data, some improved more than others. Notably AT&T’s LTE availability score rose to 71.5%, indicating our smartphone testers were able to connect to its 4G service in seven out of every 10 attempts. That’s the first time we’ve tracked an operator breaching the 70% threshold in Mexico. Meanwhile, Telcel is but a mere network tweak from reaching that same benchmark. Our users were able to latch onto its LTE signals 69.4% of the time.

4G availability wasn’t the only metric for which we saw boosted scores. Our users measured faster LTE speeds on both Telcel and AT&T’s networks than they did six months ago. Telcel landed our 4G speed award with an average download connection of 24.8 Mbps, but AT&T secured our overall speed prize thanks to better scores in both the 3G speed and 4G availability categories.

Be sure to check out our report page for the full results.
