I just received the new phone and new sim card from Koodo and activated the phone last night. I brought my number over from another provider. The new phone worked fine last night. But this morning, I can't get phone service. Can't make a call or receive a call.
First thing to try is a simple device reboot and see if that helps. If not then
Do you have signal bars present in thr notifation shade? If not make sure you didn't accidentally change the network types the phone is connecting to... It hold be on CDMA or CDMA +LTE Auto or something along those lines dependant on what device you have.
Also make sure airplane mode isnt enabled
