Dual-Sim Android devices, we thought, were relatively uncommon. No one at OpenSignal owns a Dual-SIM device, despite being more aware than most about the coverage blackspots that plague every city in the world – including our own office.
We had assumed that Dual-Sim Android devices were a curiosity, with little commonplace application and low levels of popularity. Frankly, we couldn’t have been more wrong. Upon analysing the OpenSignal device library we discovered that 25% of global devices are Dual-SIM (or Multi-SIM) and that there are huge disparities between countries and regions. For this report, when we refer to ‘dual-SIM devices’ we refer to devices that are dual-SIM capable, as opposed to whether or not that capability in use (something that we cannot detect using this specific database). We have also used Multi-SIM and Dual-SIM interchangeably, as they show up the same in our investigative methodology but most Multi-SIM devices are Dual-SIM.
The US and UK both have low levels of Dual-SIM device penetration, at 1% and 4% respectively. Markets, including Indonesia, India, Russia, Thailand and the Phillippines (which account for almost 2 billion people), see multi-SIM Android device usage at over 40% – illustrating the dangers of basing one’s understanding of the mobile ecosystem on one’s immediate surroundings. The country with the highest prevalence of Dual-SIM devices was Nigeria, where Dual-SIM Android Devices account for 66% of the Android market.
