Xiaomi is really good, nice phone, my mi6 is awesome , better than samsung, waiting for mi7, maybe, maybe....
Try an app called DevCheck to see what network your csllphone is working on, also provides much other useful info
Finally, I can confirm the phone actually works on the Public Mobile Network.
Happy with it?
Have been using MI A1 for a few month now, I'm around the Barrie Ontario area mostly. Usually receiving 3G service, get 4G occasionally.
