@mandimo Hi welcome to giffgaff and the community
Giffgaff doesn’t support business use and you will only be given a randomly selected number even if you changed which you are allowed to do twice please follow the guidance below You can port in the number if it is already with a different network but if not you only have two changes with gigaff
• Members can change their number twice
(A third time requires you to ask a agent )
•This service is only available between hours of 4.30am and 9.30 pm here ⬇️
• One thing to keep in mind is that you will have to wait 24 hours before attempting to make a second change to your number.
• Also here is a guide if you are receiving nuisance calls ⬇️
hope this is helpful for you 👍🏻
