I recently purchased a T-Mobile prepaid SIM card for my trip to the USA, and I'm encountering difficulties accessing the internet and sending MMS messages on my Motorola G22. Back home, my phone carrier is T-Mobile CZ, and it works perfectly fine with 4G in the Czech Republic.
Upon turning on my phone, I receive a message stating, "We see your phone does not have correct settings to access the internet or send MMS. Settings will be sent to your handset," along with device verification codes for the APN and MMS settings.
Following the instructions provided by T-Mobile support, I've waited for the settings to be sent and restarted my phone. However, I am still unable to access the internet, and when I can, it is at an extremely slow speed. Unfortunately, T-Mobile customer support has been unhelpful, recommending that I purchase a USA phone.
Is there any way I can manually configure the APN settings on my Motorola G22 to resolve this issue? Are there any specific APN settings for T-Mobile prepaid SIM cards in the USA that I should be aware of? I'd prefer not to purchase a new phone specifically for this trip. I would greatly appreciate any assistance or insights you can provide.
