I highly recommend loveFone. I took my two iphones, 5s and 6. One needed screen replacement and other was saying "Sim not available" Error. They fixed my 6 (Sim issue) as it was just some loose connection as I had dropped the phone. It might have taken 2 to 3 mins and they did not even charge for it. My iphone 5s screen was replaced but when they restarted they found that the logic board had problems. They recommended to take it back to apple as their was no point fixing the logic board. They put back the old broken screen and did not charge me. They might have spend atleast 45 mins working on it. As a token of respect, I purchased two screen glass protector that do at a death cheap price. Worth paying a visit if you have any problems with your phone.
