Most latest and high-end smartphones and WiFi Routers are compatible with our Multi-Network SIMs. Users on Apple, Samsung Galaxy S series and Pixel phones have had the best experience using our SIMs. Note: On a very few number of devices (<5% of the market), the Availability of features may vary by device.
Google Pixel Series: No 5G because of sophisticated “Carrier Profile” requirements. We recommend using FlexiFone as a Data-Only Secondary SIM. VoLTE may not work on some Pixel devices based on our tests.
Motorola: No support for VoLTE on dual SIM mode. We recommend using FlexiFone as a Data-Only Secondary SIM.
Sony Xperia: Our eSIMs are not compatible with Xperia devices, please order a Physical SIM instead.
Other Chinese Devices: We have seen a few instances where APN cannot be configured correctly on these devices and customers have to go though a lot of troubleshooting just to use their Mobile Data. Hence, if you have the technical expertise only then purchase our eSIMs, as we would be unable to provide any support or advice for anything other than Apple/Samsung Galaxy S series devices.
⚠️ Old and Cheaper 'Budget' Android devices:
Lower-end ‘budget’ smartphones (under £300) from Motorola, Samsung, Honor, OnePlus, Xiaomi, etc. would not provide you with functionalities like seamless network switching and access to all network bands in the UK which would mean that your experience using FlexiFone or any other Multi-Network SIM may not be as great as someone using it on Apple/Samsung S series/Pixel devices.
This is because the underlying chipset does not support functionalities like full Carrier Aggregation, Intelligent Network Selection based on signal strength. If you own one of these 'budget' phones, you should have noticed that your mate with you with the latest iPhone or S25 has better signal strength and speeds than your device, even though you are on the same network.
Using FlexiFone on these older ‘budget’ Android phones is like putting the most expensive Performance Fuel in an old banger runaround car. Instead, get a refurbished flagship device like the Samsung S23 or iPhone 13 for £200 and you’ll be much happier with your overall experience.
