I have had my phone for two weeks and have had no internet access outside of my home wifi. At my wits end so if you have suggestions/solutions I'm all ears.
What network are you on? I'm on ATT and when I received mine and placed my SIM in phone I had no data on screen, so had to go in and change the APN in order for it to recognize my data plan on ATT.
I had the same issue. Turns out a) wrong imei was used at the store and b) they put me on the wrong data plan (needed 4g, they didn't switch me from 3g).
