"Could not activate cellular data network" intermittent error?

[ahmad0410]

Anyone on M1 get this error occasionally on your iPhone 6 and cannot use the internet?

I first got it yesterday night after getting my phone. Did everything to resolve it on my end but didnt work. So i went to sleep and just woke up to check. Everything worked fine, then it pop up again, and now its fine again.

There is 4G on the top bar though everytime the error come up.

Have you tried with other telco. Just to narrow down.

I havent tried with any other sim card. Even if I could, its hard to replicate the error. Very random.

I'm on Singtel, have the same issue as well.
But my cousin's iPhone 6 and on singtel, but no such problems.

I experienced the same issue last night around 1-2am. I had 2 M1 devices with different lines and both were not having cellular data. Went away this morning. Must be M1's problem...
