eSIM.net fully support MNP (Mobile Number Portability) with the 4 major UK Mobile Network Operators ( Vodafone, O2, EE and Three ) and all MVNOs ( e.g. Giffgaff, Lebara, Tesco Mobile ) except Lycamobile, Sky Mobile and Virgin Media.
To port your number to our Pay as You Go Plan you should firstly contact your current provider and request a PAC code which they are obliged to give you.
Then email email@example.com with the PAC code and your number to be transferred in. Once received it will normally transfer over within 48 working hours. You will also need to purchase a Pay As You Go plan for the number to transfer to.
We also support porting out your number if requested. Just ask us for a PAC code and then forward this to the operator to which you want to port your number.
