That's Correct, Tmobile htc one phone with a GSM Metropcs sim card.
Sent from my HTC One using XDA Premium 4 mobile app
Hi. I bought a HTC one unlocked and i now have a Metro PCs sim in it. The gsm is working great except that inside my home i have poor reception. I would like to enable wifi calling on the phone but that feature/setting is missing. I did some searches and most posts say that it cannot be done unless the phone is bought from tmobile. Is this 100% true or is there a work around? I would love you help on this.
