3G cellular network not working - iPhone 7 can't connect to mobile internet

[lockehart]

Hi,

I've been using PM on the same 1GB plan for a couple years now. And recently my phone (iPhone 7, iOS 12) stopped connecting to the cellular network (even though my cycle just started a week ago).

I've tried changing isp.mb.com to sp.mb.com under cellular data network settings but neither works.

Please advise, thanks!

@lockehart  I have iPhone Se 1st generation older than iPhone 7 and I have the latest iOS 15.1, that might help fix any bugs, iOS 12, is very outdated, try updating it.

Some notes:

- you NEED to enable LTE now (im pretty sure it was optional before)

- isp.mb.com is fine

LTE does not need to be enabled to use data.  Data works on both the HSPA and LTE networks.  LTE is still optional, although the experience might not be as good within enabling connections to the LTE network.

I'd suggest trying in another phone first, to make sure the problem is with your phone. Then resetting your network on your iPhone may solve the problem.
