No data or call since plan change
I took advantage of the new 3gb plan to make some savings and switched to it. I also downgraded coverage from Canada to Quebec only.
As the plan took effect yesterday, I immediately lost LTE and ability to call and receive calls. I seem to be able to send and receive texts. LTE constantly switches between on and off so I'm able to receive internet chats sometimes but it's mostly not working. Phone calls just don't work in any direction.
On top of this the new volte SIM I received did not activate successfully and I have to use the older SIM. This happened prior to the plan change but did not interrupt service at all.
I don't know what to do and neither does technical team it seems.
