you say the problem still exists after a factory reset but in the store with a new sim it was working as it should?
so seems you are only having issues at home? when you are out and about the phone works normally? am I correct here?
Phone is not rooted as far as I know (I'm not a techie) - was purchased used and unlocked from eBay. The sim from my HTC was put in a spare phone in the store (wasn't a new sim) and that phone was able to send/receive calls and texts. I've tried using the phone at home and work without success. The signal at work is good. I'm on android 4.2.2. As mentioned earlier internet works fine using wifi or mobile network.
