I just posted this a few minutes ago:
I have an LG Optimus Ultimate. As of yesterday, I can no longer send/receive picture messages, or connect to the internet in any way, not through the browser, app store, and my apps that require data are not working either. In my settings it is telling me that my Mobile Network State is disconnected. Airplane mode is not on. Straight talk said they can not help me, because I do not have another phone number to call from other than the one I am having trouble with. Does anyone here have any idea how to fix this? Thank you in advance!
During my live online chat with a representative, it got disconnected while my phone was going through a factory reset, which DID NOT fix the issue. Any other ideas?
