I used this phone awhile ago but I got a new phone because this phone had touch screen issues but I realized that it now works fine, so afterwords I eventually switched back to this phone so it now has service. So when I switched, the lady at metro pcs just simply took the sd card off to get the details and that's all. So the phone was working well until I went out to the movie theater and apparently a friend was going to pick me up but she sent me a message about how she couldn't so I had to call someone else. I thought it was because I had no service so I shrugged it off but I began to realize my sister and mom sent me messages but I haven't received them, I did Google research and I did a reboot and even a factory wipe reset but it still does not work. I sent myself SMS messages and they don't send back, but if I send myself a MMS I receive them seconds later, I don't know what to do. I have reset , reboot , and just erased everything but it doesn't work. My last resort is to call metro and see if they can do anything, but before I do I was hoping any of you would be able to help. Please if you could help me , I really need to receive these messages because of work , family , friends. I was questioning if maybe it's because the SIM card but I'm not entirely sure. Everything else works fine, I can call and I can receive messages as well as I can send messages, but just not receiving them. Please if you are willing to help it would be greatly appreciated.
