STC’s *150# doesn’t always show your number right away — on many phones it opens with a language choice first, and picking the wrong path through that initial menu is the most common reason people think the code “isn’t working.”
Quick answer
Dial *150#. If a language prompt appears, select 2 for English — your number then displays.
Navigating the menu correctly
Some phones show the number immediately as a flash message; others present a menu starting with a language choice. If you land in a numbered menu after selecting English, look for an account-information option (often “1”), then a sub-menu item for “My Number.”
If registration is the actual problem
A response of “service not available” usually means your SIM’s registration wasn’t fully completed — this isn’t a menu-navigation issue and requires visiting an STC store with your Iqama or national ID.
Skip the menu entirely
The MySTC app shows your number on the profile screen the moment you log in — no menu, no language prompt.

Troubleshooting
*150# shows a menu I cannot navigate
The first prompt is usually language selection. Press 2 for English. If you see numbered options, try pressing 1 to access account information, then look for "My Number" in the sub-menu.
*150# returns "service not available"
Your SIM registration may be incomplete. Visit an STC store with your Iqama or national ID to complete registration. Alternatively, call 900 from another phone for assistance.
