This says to me that either the phone isn't compatible, the network settings are incorrectly set (you require a 3g/HSPA network for phone calls at Public Mobile), or that there was a provisioning error during the activation process.
@cda did your credit card renew recently? Did you receive a replacement card and forget to update it with PM? You could try manually selecting PM as your network and restart your phone. Stay safe.
@cda Put your phone in airplane mode for 5 minutes and then back to normal. Also try restarting your phone. If you are still getting the no service error and you just activated your account then your account was not provisioned properly. You need to click on the "?" and submit a ticket so that the moderator can reset your account.
@cda Please give us more info. Did you have it before? Did you port your number? What is your phone model? Did you try restarting phone or enabling/disabling Fly mode? Thanks.
