Thanks for your help! I enabled roaming, am sure to have the US plan, am using a Xiaomi Mix Fold 3 with the latest HyperOS version. This is not a common phone though... I don't have any cellular access (phone, text, data)
I am new with PM, I have the 50GB US/Can plan. Didn't have the chance to try in another state. I tried Verizon as well and GCI, but get the same result. Thanks!
