Hi and Welcome to the Community!!
Please ensure that you have ALL voice services (calls, voice mail, SMS) working properly from your provider. Then, with a strong signal to your carrier network (no WiFi!!!), please ensure that you are exactly following this:
You should see the pop-up that the registration message has been queued...then, following that, you should receive, into your main Messages app, one "registration" message.
If this does not happen, then you must contact your mobile service provider (STC, according to your profile here) for formal support. It is there network with which your BB is having trouble communicating, and only they can look "behind the scenes" to find out why.
