No service issue in iPhone after updating to iOS 15.8

My husband’s iPhone 7 updated to 15.8 and worked fine in the A.M. and midday he received an error message saying cellular data not connected, or something like that. He wasn’t able to make calls or send messages after that. Once home, he was able to send and receive iPhone texts, but still the phone is searching for service. He called iPhone tech support and they said he’d have to go into the store to have them check the phone. I wonder if the SIM card is fried! Thoughts on the update being an issue, I’ve read other older model iPhones like 5 & 7 both, having the same issues but with other updates and not this specific update.

Troubleshooting - iPhone 7

Remove and reinsert the SIM card.

If it doesn't help visit your carrier, maybe the SIM card is damaged, ask for a replaced (new) card. Normally it is free.

Ask also to check if the SIM tray is bent, as even a tiny misalignment can cause the SIM card to not fully connect with the internal contacts in your iPhone.

See these Apple articles below:

If you see No Service, Searching, or SOS on your iPhone or iPad

iPhone 7 is > 7 years old, which also affects the battery life. The hardware remains old, so does the battery.

If it is still possible, have the battery replaced.

The battery can be replaced by Apple or an Apple Authorized Service Provider.

See this Apple article: iPhone Battery Repair & Replacement - Apple Support

If you are going to replace the battery, see -> Get your iPhone, iPad, or iPod touch ready for service

Get your iPhone, iPad, or iPod touch ready for service - Apple Support

The price is approx $ 79.

If you want to know exactly, call Apple directly, see Contact Apple for support and service -> Contact Apple for support and service – Apple Support (UK)

call 1-800-MY-APPLE

note:

You have to decide for yourself whether it is still worth having the battery replaced.

Considering a newer type of iPhone?

I have iPhone 7 worked fine then upgraded to 15. Something which now keeps disconnecting me from my wi-fi constantly and now it’s saying to update to 15.8.1 which I too believe it’s a way to damage a chip in your phones to make force you to buy newer model..apples bad customer service and bad updates and they won’t help!

I’m having exactly the same issues. Can make and receive calls on an I phone 6 15.7.9 but not on my IPhone 7 after updating to 15.8.2. Everything else is working fine and am really frustrated at not being able to get this sorted.

Please fix it mobile data issue on ios 15.8.2 for iphone 7 or below. Not all of us can buy the new latest iphone just because of mobile data issue happens after updating ios 15.8.2 on iphone 7. Apple should be aware and please take action about this. Not just focus on the latest ios for the latest iphone. People who still using the old iphone must be a reason or something else.

My issue is similar in the sense that after installing 15.8.3. My phone no longer recognizes my international SIM. I have a Globe SIM that worked fine. Then updated and now it won’t connect. I tried the cellular settings and no luck. Hope it works when I go back and visit. I may also try and add a load to the SIM and see if that affects it.

Due to this 15.8 upgrade that turned my iPhone 7 into a paperweight and other frustrations with Apple, I purchased a new phone from another manufacturer.

Did it give you a message saying you will not be able to set up this iPhone after erasing ?
