Your post doesn't really make sense to me.
What exactly are you asking (for?)?
What's a "portal id"?
If you want to port your number from another carrier to 48 then see here:
https://community.48.ie/t5/The-Knowledgebase/Getting-Started-Move-Your-Number/ta-p/53100If you have problems with the porting process post back with detailed information of what you tried, what didn't work, any error messages etc.
Or contact 48 support - see the link in my signature below.
Hope this helps.
