Works good but is limited depending on your internet connection

It works with some WiFi Networks not all, I may be a problem related to my soft-phone service provider but I’m not sure. It does not work on t-mobile cellular internet yet it works with other cellular providers internet I tried using a different sim card and I am unable to log in with my T-mobile one.
