Yes. If the device is purchased from outside, it must support e&’s current 5G frequency bands:

• Band n78 (3.5 GHz)
• Band n41 (2.6 GHz)

e& will continue adding more 5G frequency bands which will be communicated through necessary channels.

If you have a dual SIM (physical SIM and eSIM), you can start enjoying 5G services after the iOS release in March 2021. Please note that 5G will be turned ON by default. You can disable it if you like.
