Text Messages Coming In Hours Late

[myhollowworld2]

So, when ever I go to my friends house I have no service. That's ZERO service. After I leave, I get text messages with time stamps from hours before. Not only that, they come in out of order sometimes, (ie I'll get one from 9:45, then 9:30). Even when I send and receive new messages, they just appear randomly.

I'm running stock everything, and this has always happened since I've had a Mogul. Would I need to edit some settings under the EPST? I don't have my MSL so if there were the case I would need to obtain that first. Any input would be appreciated, thanks
