Cellular data keeps turning off randomly

I have the new 12 pro max which I preorder and put my old chip in and I have been having this issue every couple days or so, my data does not work I am unable to make calls or send text messages or anything, turning the phone completely off and back on seems to work but that’s become a nuisance. What is wrong is there a way I can fix this?

We're here to help with your data connectivity @jim_s.


To point us in the right direction:

  • What is your zip code? We want to check tower stability in your area.
  • Did your new iPhone 12 Pro Max come with a new SIM? We highly recommend using it or picking up a new SIM.

In the support article above, please try using our SIM troubleshooting tool as well. You may also sign-in for a more personalized diagnostic.


We look forward to hearing back from you.
