Switched from ATT, Now Major Problems

Hello Everyone,


I had pre-paid with ATT on a Phoneix LG phone.  Since switching to T-Mobile a little over a month ago…


-I can’t send images

-I can’t reply on group texts

-Randomly a few times a day, my phone will not let me text or call until I restart.  (Friends who have tried to call are reporting it goes right to Voicemail during these times.)


To make matters worse, T-Mobile over charged me on my last bil, but they have promised to restore those funds eventually.
