Network issue in iphone 12 pro

iPhones don't support carriers. Carriers are the ones that need to support iPhones.

Why do you think Airtel does not support your iPhone?

Airtel seems to support iPhones fine in India and Africa:

Wireless carrier support and features for iPhone in the Middle East and India - Apple Support

Wireless carrier support and features for iPhone in Africa - Apple Support

What issue are you having exactly?

What happens when you try to use your sim card exactly?

Yeah many others are facing issue https://timesofindia.indiatimes.com/gadgets-news/some-apple-iphone-12-users-are-reporting-4g-network-issues/articleshow/79531138.cms

i think you should port to other network may it solve your issue in other network

Once I changed my old Airtel Sim to a fresh one, the phone is working flawlessly. My issue was not poor network though - i was simply not able to connect to the network with the old sim.

Apparently on Airtel you have to get the e-sim activated for 12 pro to work.

If Airtel can find no issue, then contacting Apple Support is the next thing to do: Get Support - Apple.com

It won’t toggle it will remain on permanently but your problem will be solved i think so because i was also facing same issue 15 days back when i bought my new iphone12 pro i had purchased vodafone sim and I wasn’t able to call anyone from my vodafone sim call was getting failed so someone suggested me to toggle show my caller id on and after that i was able to call from vodafone sim

There is no such thing as a universal model.

Only Apple sells unlocked devices.

Are you sure you have an unlocked device?

Go to the phone settings > show my caller id > select airtel & switch it (on/refresh) hope it will solve your problem :)

Do you have a sim in the device?

Did you buy an unlocked version?

Which country iphone model you’re having because iam also facing issue in my Vi sim for my iphone 12 pro japan model MGMC3J/A

I was using my IPhone 11 Pro when I went to Dubai I had International Roaming activated on my Airtel SIM card

mad soon as I got my New iPhone 12 Pro I inserted the Airtel Sim and it instantly started working without any issues

I landed back to Bangalore from Dubai and the IPhone 12 pro with my Airtel sim was still working Absolutely fine yesterday 27th evening I took a Flight from Bangalore to Mumbai and when I landed in Mumbai at 10.15pm I switched on my IPhone Since then I am Unable to Get Network on the IPhone 12 Pro

this is Crazy

I have a japanese iPhone 12 pro unlocked model. I earlier used jio sim , now i also have airtel esim which is having a lot of issues. Airtel 4g doesnot work it drops frequently but jio’s LTE works fine.

airtel 4g stops working after some time .

what should I do ? Please help !!

bro :) haha what problem exactly you’re facing tell me clearly are you not able to call from your airtel sim or not able to use internet of airtel sim i think there is some misunderstanding between tell me clearly

My idea (Vi) sim is also facing network issues. There is no stable network. It keeps disappearing and appearing. I changed my sim .. no use. I have iPhone 12 mini.. Was planning to change my network provider to Airtel but seeing your comment here I am not sure now. Is there update over this issue. It seems people all over the world are facing network issues with iPhone 12 models
