iPhone 7 won't reliably connect to telco network

Phone connects sometimes but then loses connection. Sometimes a power down fixes it but at other times it doesn’t. Telstra Auatralia has “Telstra Wi-Fi Call” that saves the day but only when I can connect to a Wi-Fi network. Intermittent issues are a PAIN.

Fortunately my iphone 5s works still so I can swap the SIM and make a call if I need to.

I have done all the basic settings fixes.

Help would be most appreciated.

Answer this question I have this problem too

Is this a good question?

Do you know if the audio IC has been worked on?

No it hasn't.

Most of the time it's a few loose solder balls under the baseband chip which controls the 3G / 4G network functions when that develops a loose connection to the board the signal keeps resetting resulting in drop outs like the phone has no reception.

Don't think it's worth fixing IMO the repair is $180 but in the long run it's better to just get another phone that isn't the iPhone 7 / 7 Plus and is newer as that model is rampant with Audio / Baseband chip related problems.

Backup ASAP as once these chips become more loose they will cause the phone to get stuck on the apple logo.

Thank you very much Ben.

I have every thing backed up.

It is strange that these models have been so poorly designed/ manufactured.

Thanks for taking the time for your detailed response.

is the sim card relatively new or have you had it for a while. they do out date if they are old and can intermittently lose signal. people used to have this issue when I worked for telefonica o2 in the uk and replacing them for a new sim would fix the issue, especially in newer handsets capable of better connections.

Hi Jay,

The SIM card is about 5 years old. I’ll get a new one from my Telco. Thanks very much for your answer.

I am still trawling the net for possible solutions. One I came across yerterday was related to the celluar antenna. The chap replaced it and he regained connectivity.

That still leaves, I think, the internal modem as a possibility. I don’t know whether it is swapable.

Thanks again Jay

Hi Jay,

I installed a new SIM card today. Connectivity was established but lost after about 2 hours.

I think I wiil try replacing the celluar antenna.

Any thoughts?

Internally, the antenna that connects to the network might be damaged from a hard fall or shock. You might check the antenna inside of the iphone. Best of luck, Apple Maniac.
