I have Verizon data and overnight it changed to a completely different internet provider which is called Alliance partner Verizon can give me no help and United Partners said it was impossible but yet I have the screenshots and a phone that is no longer working because of that provider how could that have happened and what can I do a SIMs card is not solving my problem also and it also says unusable SIM card.. could this have anything to do with the device administrator I see there has been a few changes in my settings which I did not authorized what do I do ? Alliance partner says that's impossible and Verizon support says they have never seen anything like this I guess I might have to just get a new phone which is not pleasing me at all ..please help anyone??!
Your provider(s) need to assist you with this, as you are already paying for support. Why have a free forum fix this when you are paying for the service?
My free advice is to jump up and down in your providers store till they fix it, or wipe it back to factory, and start over. Or better yet, wipe it in the store and hand it back to your provider and tell them to cancel your services as they are providing you no SERVICE!
