A friend of mine bought a Nexus 5 and had it for a week and it worked perfectly. He decided he wanted to sell so I bought it off him. We did a factory reset on it to delete all his data etc off of it and after when I put my sim card in and went to set it up to use it, it doesn't connect to my network automatically. When I choose my network in the setting it will say "registering to network" and then say "can't connect to network at this time please try again later" I have tried using different sim card from different companies and it still does the same thing.
Please Help!!
