Solved: iPhone 6S No Signal No Service Issue

Before us going to solve iPhone 6S no signal no service issue, we need to know what causes this issue. According to our repair experience, there are two reason, one is signal receiving part damaged, the other one is signal transmitting part damaged.

The iPhone 6s has no service with sim card but it shows operator in the setting, which indicating that there is no problem on the signal reception, so we judge the fault is on the signal transmitting part.

The signal transmitting part is sent out from the RF IC chip through the 2G amplifier chip and then through the iPhone antenna switch chip.

In iPhone repairs, the 2G power amplifier failure probability is very high, so we replace the iPhone 6 2G amplifier U2GPA_RF chip by QUICK 861DW hot rework station and related professional repair tools, but the same failure still exists, it seems that the 2G amplifier has no problem.

So we have to transfer previous judgment, now we are going to replace the iPhone 6S radio frequency IC U _WTR_RF chip, it finally shows normal and also normal for calling or receiving calls. So, it is found that the RF IC U_WTR_RF chip damage can also because cell phone has no service.

Finally, assemble the iPhone 6S, you can use it normally again. More information, please visit vipprogrammer
