What should I do for my new Huawei Mate 20?

I used Huawei Mate 8 with AT&T sim card last year, it didn't get LTE but only "H+", and now I will change my phone to Huawei Mate 20.


What should I do additionally to make the best use of this phone with AT&T sim card (for example, get LTE speed)? Do I need to go to AT&T store again to adjust something? Or can I just plug in the sim card to my new phone?

Hello @yesluck


It's always exciting to upgrade to a shiny new device, We can help you with that!


To make sure that your new cellphone is compatible with the AT&T network, you can access our AT&T Bring Your Own Phone (BYOP)  and provide more information including the IMEI number associated with the device for further assistance.


We hope this information helps.
