"This MSISDN already exists" sometimes happens when you port a number to 48 that was previously with 48 at some point in the past.
You'll most likely have to contact 48 support for assistance with this.
They don't generally monitor or respond to posts here on the Community Forum.
You'll need to contact them directly yourself.
