The simplest method if you have access to another phone (a friend's, family member's, or even a landline). Just make a quick call or send a text message to that phone, and your number will show up on its screen (Caller ID).
Contacting Vi Customer Care:
If the above methods don't work, you can call Vi customer care:
Dial 199 from your Vi number (toll-free).
Dial 198 from your Vi number (toll-free, primarily albania phone number list for complaints/requests). A customer service representative can tell you your number after verifying your identity. If you're a Vi (Vodafone Idea) mobile user in India and need to find your own phone number, here are the most common and effective methods, many of which involve checking directly from your SIM or phone settings:
Using a USSD Code (Quickest Method):
This is the fastest way and works directly by querying your SIM card's services.
Open your phone's dialer.
Dial *199# and press the call button. Your number should appear on the screen as a flash message or within a pop-up menu.
If that doesn't work, you can also try *131*1# or *121*2#.
Your phone often stores your number, which it reads from the SIM card.
