I cracked the screen on my phone in September 2016. I then processed an insurance claim which included paying a $200 deductible after paying $700 for the original phone. T-mobile's insurance company sent me a refurbished phone. On May 11, 2017, my iPhone 6S Plus purchased by T-mobile popped up with a 'No Service' in the upper left corner although there was an active T-mobile sims card inserted. I immediately went to T-mobile to have them look at it. T-mobile said that it was not their phone. I then sent the phone to Apple. Apple did a full diagnostic of the phone and stated that it is in fact a T-mobile iPhone. They also stated that the reason for the 'No Service' issue was due to unauthorized modifications done by T-mobile. I then contact T-mobile again and they said that it was nothing that they could do because the warranty on the phone was up. At that time, I was told that the warranty was only for 6 months versus 1 year, what a coincidence. T-mobile stated that I could process an insurance claim which would consist of another $200 deductible. I stated to them why do I need to process an insurance claim and pay a deductible for something that T-mobile did to the phone to cause it to go out. At this point, I am paying for phone services that I am not able to use because I do not have a working phone and cannot afford to purchase a new one. I have entered a BBB claim hoping that they can help me with this situation. This discussion is for those to receive a refurbished iPhone from T-mobile and have issues. Apple stated that they see this all the time and service providers such as T-mobile should not be refurbishing phones and that they should send them to Apple to take care of. Service providers are not authorized to refurbish Apple product, only Apple can.
