Weird how it's worked fine for 2 weeks, then all of the sudden today it has this issue.
On a related note, will I be able to replace the phone at a Verizon store if I purchased my phone through Costco? Only reason I ask is because Costco is a 1.5 hr drive away and Im not willing to make a 3 hour trip to 'try again'..
I am having the same issues too. Will have data for a couple of days and then nothing. I tried the airplane mode and that does not work. I have to do a hard reset on the phone for it to come back on. At first I thought I just had a timer on that I didnt know about. But it looks like its a common problem.
follow this thread to stay abreast of no data signal (3G/4G):
No 4G / 3G or network connection after waking PLEASE HELP
