[1337] "No SIM" error after unlock - GSM-Forum

Hello Z3X Community,

Mr Blang Please I need your input on this issue.

I am getting this random issue with MULTIPLE I337 ATT Galaxy S4 phones after unlocking. After unlocking the phones with Z3X, MULTIPLE I337 Galaxy S4 Phones are getting full 4G and signal with ATT but when T-Mobile Sim is inserted...The phone says "NO SIM"

This is really big problem and I'm not sure if it's with Z3X or the phones. I have heard other people having this issue but no explanation. I do not understand why phone will detect ATT SIM fine but it says "NO SIM" for T-mobile.

Please Z3X team I would like explanation of this issue. Do you think this is phone problem or Z3X problem???

Thanks!!

hello friend this problem is not caused by Z3X nor too little unlocking process this problem is an intermittent fault on the board as it does not solve changing sim reader and tried several tests with the model I337M and 'running well with a regular sim card failure comes out when LTE hope this is helpful
