Try using a different sim card, just for testing purposes (ask your friend or partner to use his/her sim card for a minute). Replace your sim with this one and restart your phone.


Additionally, this may also happen if you are in roaming, but it is switched off. If so, try Mobile Service > [Select your sim in the list] > Data roaming - should be ON.

Me too since the update to iOS 17.1.1 the iPhone SE 2020 is no longer asking for the sim-pin and if the sim dialogue shows up there is no mobile data exchange happening.


I have no ideas what Apple is doing in the last years but there are too many basic bugs. I hope thy fix this one over night because I need my iPhone for working tomorrow…


I did try the hot reset with no avail. What now Apple?

My data hasn’t been working either. I’m thinking it’s maybe the carrier atp because the same **** was happening with my last phone because I thought maybe the phone was the issue the whole reason I upgraded to the 14 was because I thought that would resolve the issue but just like when I first got the 11 my data would work for like a day or two and then never again. The ***** so annoying when I paid this much for the phone AND it’s data but I can’t even use it😑

My iPhone 12 won’t let me use data also. I am not going to purchase another phone all cause of an update that Apple had to do which was, in my opinion, unnecessary. Now I connect my phone to my works WiFi because I cannot even text properly or send out text without it. Not can I make calls and I have done a reset on my phone hoping it would work out but nothing is really working. I called my cellular company and they couldn’t help me. I am not purchasing a new phone if I don’t have too.

I’ve been having the same issues with my phone going to SOS. I have an iPhone 13 ProMax and I have Verizon service. Does anyone else have Verizon? Just wondering if it is the carrier.


It was suggested that I get a new phone but I don’t feel like the hardware is the problem.


My daughter has the same phone but through TMobile and has not had this same issue. We both have done the IOS upgrades as well.

A couple of weeks ago my Iphone 14 Pro Max stopped using mobile data. Fine on WIFI. I have reset network settings numerous times, now won't download photos from people in messenger or messages. I thought it was just my phone until I found this site. the phone is getting worse by the day. Apple need to seriously look at doing something about it seeing it was caused by there latest update!
