My iPhone 11 Pro Max stopped reading SIM cards

Are you getting any error message when you try? Did you contact your cellular carrier about that?

Are you seeing "no service"?

If you already tried (to no avail) all the steps provided in this support article:--> If you see No Service, Searching, or SOS on your iPhone or iPad , it could be also a SIM tray (holder) problem (even if it is very rare), but I suggest that you make an appointment (*) and have your device inspected at an Apple Store or AASP (Apple Authorized Service Provider) among this list:--> https://locate.apple.com/choose-country-region . After checking it out, they'll give you all the available options.

(*) You can do it:

• Online:--> Genius Bar Reservation and Apple Support Options - Apple;
• Contacting a local Apple Store or AASP among the list provided above;
• Using the "Apple Store" app, available and downloadable from AppStore.

After updating new iOS the a few days after that my signal gone as well.

I tried all of the above ways on my iphone 11 pro max.

Call the carrier company they say there is no problem with the sim card. Try to put on other iphone works well.

I try different sim card from different provider also not working.

Using the eSim still showing No Service.

I am curious that the latest update force us to buy the new iphone.

If no, please fix the problem.

Contact 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.

my iphone 11 encountered the same issue after ios17 update.

its not just stopped reading SIM cards, it constantly overheating my iphone 11 pro. Apple should fix these issues asap.

Then what you had done my phone showing similar problem

Plzzz suggest the solution if some one got anything
