@lucastanciu also, this is an open forum, remove your phone number for your own protection. Go back to your post, click Edit Message and remove the phone number
And if your account is active, check what the phone status bar on top showing. Does it show connected to PM network? Does it have error like SIM not provisioned? No sim?
Try to first reboot the phone.
If it still does not work, try to reseat the sim card. Power off the phone, take sim card out for a minute, then put it back and power up
And try your phone in different area, could be a local network problem.
