Who I have the same questioned this topic

Phone shows 1-2 bars for signal strength, but data does not work at all.  Cannot receive texts, emails, etc.  Have done all the normal fixes: turned airplane mode on then off; turned cell data on and off; restarted my phone multiple times, nothing works.  I have been having call dropping issues for several days, and now I've got no service at all.  What is the problem?  I have always bragged about great my service is, but that is coming into serious question!
