Hi, I recently changed the body of the my iPhone 5s recently. I also got a new nano sim for the phone. Whenever I insert the sim, it shows full coverage and after 5-10 minutes it drops and shows no services. Does this mean that the cellular antenna is damaged? Where is this antenna and how can I replace it. PS: I user the same sim in different iPhone and it works perfectly well. I also tried putting another sim in my iPhone but again the same issue. Please advise.
You SIM would not affect your signal strength. With a small exception that your provider may turn off your service and cause you to show no service due to the SIM. This does not appear to be the case. Your service antenna is attached to the lower doc: https://d3nevzfk7ii3be.cloudfront.net/ig… Make sure it is attached properly. My guess is there is probably something else wrong. Usually if the antenna is the problem the service is either crap or not from the start. Hopefully it is as simple as making sure it is plugged in all the way. Good luck!
