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!

- 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.
