Why Do I Get No Service After iPhone Unlock?
Reason 1. Maybe your iPhone is barred, blocked or blacklisted by your network. The gadget might be also listed as stolen or lost or the previous owner [if you got the used model] didn’t pay the bills to carrier. If this is the reason you can easily find everything out by using IMEI blacklist checker. You can also try to contact the original carrier and try to fix everything on your own.
Reason 2. The iPhone 6 and iPhone 5s are both using Nano SIM. If you are trying to insert the Micro SIM or regular SIM card you will not succeed because your handset can’t detect it. Try different SIM [maybe from a different network] and better find Nano SIM to successfully get the service.
Reason 3. Any iPhone model, including the iPhone 6 and 5S, can break if it falls. This could also be the reason that causes No Service message. If the issue is with your hardware you can only take the phone to repair center and have it fixed.
Reason 4. The network you are trying to connect to after unlock might not even be covering your area. If this is the issue you have to find a different carrier SIM.
Readon 5. The issue can be with the SIM card. It might need to fix. If you insert a different SIM card and get the signal you might need to contact your network [the one for which the SIM card is not working properly] and find a solution.
Reason 6. If you have issues with antenna you might not get the signal. Take the iPhone to the service center to have it fixed or better take it to Apple and get the replace.
Factory unlock always guarantees the permanent result if your iPhone is not broken, blacklisted and has no other issues with network or hardware.
