Do I need a new SIM card if I upgrade my device for the 3G closure?

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

However, it is important to check the size of the SIM card required for your new device.

If your new device requires a different SIM card size than your current one, you may need to obtain a new SIM card or use the SIM card insert that came with your 3-in-1 SIM starter pack.
