No Network connection unless on Wifi.

[johnfishcurtis]

Lumia 640 LTE (UK EE)
Win10 15184

In the last 2 days the phone has lost network connection unless on WiFi....... it seems since MS updated Mail and Calendar for Win10 on Tuesday.
I haven't changed any settings and when off Wifi I get "no network" displayed, it just doesn't work for Hike, Weather, News, Windows Central, MS Edge etc.
Making and receiving calls is fine.
Any idea's?:shocked:

Same thing happened to my Lumia 625 on build 10581.
It was showing no service.
I did a hard reset and it fixed the problem.
