Cellular data not working after 11.2.5 upgrade

I have an iPhone X. After upgrading yesterday to 11.2.5 cellular data isn't working. I've tried everything I can think of, turned phone off numerous times, reset network settings, restored from backup from just before upgrade (forces me to install 11.2.5 after restore), turning off/on mobile data etc. When I turned on data roaming I was able to use cellular data for a minute and then it stopped working again. I've been able to get data working a couple of times by turning on/off data roaming but it's only for a very short time and then it stops working again.


It's not my provider or local reception/tower, as my wife is with the same provider and everything's fine on her phone which hasn't yet been upgraded. I'm at a loss as what to do next.

iPhone X, iOS 11.2.5

Contact your provider and verify that:

  1. Your account is provisioned properly
  2. They don't have a local network outage

Same issue. As far as the other response, he said his wife's phone works and is the same provider. Same with me and my husband. It happened after the update overnight. I have tried all...resetting network setting, sim card, etc. Before I do a wipe (which is a PIA), I want to know if others are experiencing this and if there is another update coming out asap to correct so I avoid wiping my phone...

You didn't read drewbytes response, which was that his provider needed to fix the provisioning of his account.


So you might try checking with your provider also.
