I have had the HTC Evo for most of the year and I haven't had too many problems. Though, I have had to factory reset it three times because it has 'run out space' so it will block me from opening my messages or photos. Last Tuesday I had to factory reset it again and this time something happened with my messaging. I can send texts, but I can't receive any. This has never happened before, what could've happened and how could I fix it?
Have you tried sending yourself a text message? Let's try updating the profile (home/menu/settings/system updates/update data profile) and remove/replace the battery and then try to send yourself a test text message. Let me know if that fixes it because if not, I'll private message you and we'll work on it together.
