I recently purchased an LG Vortex. Today I discovered I cannnot use the apps. The messages I receive is either "no network service available" or "network error" or "service no available." We are on a family plan, and I just purchased two other Vortexes after trying this one out for a few days. IT was operating without problems until today. Thanks.
You didn't happen to turn off the 3g network connection, did you? Turn on the airplane mode?
Can you try connecting to a wifi network and see if it works that way?
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
