Existing ALDImobile SIM cards are compatible with 4G and 5G mobile devices.

However, it is important to check the size of the SIM card required for your new device. Our SIM cards are “3 in 1” which means they have a standard SIM, a micro SIM and a nano SIM all in the one card. You simply add or remove the insert frame to match the size that fits your device. 

If your new device requires a different SIM card size than your current one, you may need to add or remove inserts. Newer devices typically require smaller SIMs so it is most likely that you will need to remove rather than add an insert to fit a newer device.
