Make sure your SIM is SA 5G compatible
If you purchased a T-Mobile 5G compatible device, it came with a 5G SA compatible SIM card in the box! You just need to activate it.
If you’re not sure you have the right SIM in the device, pull out the SIM card and see what’s written on it:
R15: If you see R15 in pink on the SIM card, you’re all set!
Manners cost nothing, and also have the added benefit of making a man. You know, it is entirely possible to rise above others, without stooping to pushing them under, and putting them down.
