Dear Community of IFIXIT, After inserting the SIM card, the smartphone almost always recognizes the SIM card, I can and would say the phone recognizes it to 80% after inserting the SIM card! But after the SIM Pin input, the phone indicates that the SIM card is locked. (By the way , this SIM card works on other smartphones, i tried it on a lot of other phones) (This is a SIM card of the same telecom operator of the smartphone, which means that this SIM card must be read on the phone). I sent it to a repair center. They said I should buy a “flex on button” and exchange it. What do you say, good idea or not? Very important is also: When the smartphone such for a telecommunications network, which is one of the first steps of the mobile phone, it doesn´t found any network, also after an hour!! A software update has been created, but it doesn´t help. I think the antenna is defective, what do you think? As a attachment you find a video, from the phone, that proves that it doesn´t find any telecommunications network! Greetings Help-me-jojo

Ultimately you could consider replacing the SIM card reader based on this “the phone recognizes it to 80% " and your stated other issues. Now it will be up to you to disassemble your phone and to take a look at the SIM card reader as well as your antenna.
