I am looking to take out a new phone contract with iD mobile and keep my existing number with Vodafone for the next few months until that contract runs out to avoid paying an exit fee.

Will iD allow me to port my current Vodafone number over an existing iD number? The idea is to disconnect the new iD number and transfer my old number over, but with a couple months delay to keep my Vodafone account active in the meantime.

Thanks in advance.
