Hi….I retrieve my line but it’s still not working

Hi, I can't retrieve my PUK number and this my mtn line 08033120700

I misplaced my number and in diaspora, how can I retrieve my mtn line while here pls. Thanks

#how can I retrieve my lost...

My line was gifted with minutes but if I try to call other numbers it's saying this call will be disconnected due to insufficient balance
