In the last week or so, I've been having a problem with receiving and sending texts and calls. I contacted Verizon and they managed to get it functional for about a day or so, but the problem seems to reoccur and the tech support seems to dismiss my claims and gives me the temporary fix once again. It seems to be as if I can send a single text or call out every once in a while, but then stops entirely. More so, I am just curious about whether or not it is a problem with the phone itself or the provider. Any help would be greatly appreciated.
Edit: Not rooted, Android version 2.2.1
Also, it seems as if I can make a call or send a text here and there after I restart the phone, but then the problem persists.
