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
