iPhone 6s network problem - GSM-Forum

okrongly · 09-14-2016, 11:58

Hello,
Have one iPhone 6s with network problem.
Phone was dropped, no bars on reception, but network name shown. Also there is data connection, but impossible to make voice calls.
Any ideas where to start ?
Thanks in advance

HI THERE if it show the signal bar but are empty and when u want to make call it drops it means that the hand set is blacklisted in the country u r using.

Phone was Dropped - so my understanding is Power Amplifier - alternative also could be blacklisted

Hi,
Basically network problems are hard to be solved. why is that ? they are connected to so many items maybe over 200 items ! (Coils,caps ics ....) anyway just to recap you may do the following (if you are lucky it will work):
1-replace antenna
2-re heat BB_CPU
3-re heat network parts
4-You maybe unhappy if you spend all your time in testing all the parts ! ! ! I would repair 150 phone for one phone that have network problem that is my own opinion
wish you the best of LUCK !
