Swapping Phone Numbers

[Anonymous]

I have 2 phones with O2 (both pay monthly), each with their own phone number and phone/data allowances used by different members of my family. Each account has different data allowances. Is it possible to swap the phone numbers between the accounts?

No not without losing one of the numbers.
You can just swap sims between the phones though.

You can swap the sims between each phone but not the numbers

Thanks for the response. Understand I can swap SIMs, however not quite what I would like. One has 3GB data, other has 1GB data. I want my son to have the higher data but do not want to change his phone number. Reading other posts, I understand you are allowed one change of number free of charge. So would I not be able to just swap the phone numbers between the accounts.

Thanks.

As said already no.
You will lose one of the numbers.
You will have to up your sons data allowance and then drop yours on renewal of your contract.
