If they haven’t already you will need to request a PAC from VM by doing the below:
Text ‘PAC’ and your date of birth (in DD/MM/YYYY format) to 65075 For example: PAC 01/03/1984
Once you have this you will then need to provide this to O2. The easiest way I have found is to go to
here and provide them with all the info.
Hope this helps. It avoids having to speak to anyone and also should compete next working day if you complete the O2 form before 5pm Monday to Friday.
Once all competed your old Virgin Mobile sim will no longer be active and your number will be moved to O2.
