Swapping SIMs numbers between 2 active O2 contracts

[Hopeful2BHappy]

Hello everyone,

My question is complicated, so bear with me whilst I explain, please.

My inquiry is about 2 of my monthly contracts phones:
- mobile A has tariff B and number C;
- mobile D (my new phone) has tariff E and number F;

I would like to swap number C with number F, so I will have:
- mobile A with tariff B and number F;
- mobile D (my new phone) with tariff E and number C;

Please advise how this may be possible to be achieved.

I do not intend to cancel any contracts.

Thank you all in advance

For what you are asking you just need to put the sim cards in the different phones.

Hello,

Thanks for the reply.  I probably didn't explain well enough.

Account A / SIM A / Phone number 1 is my current main (known by all my contacts) phone number with a 6Gb data allowance.

Account B / SIM B / Phone number 2 is an "extra" SIM with a 50Gb allowance.

I would like tomove my main number to the SIM B and have the 50Gb allowance available to me on my main number and move the other to the other SIM.

Moving the current SIMs between phones doesn't achieve what I would like.

Thanks, Frank

Simply not possible.

Depending what phone you have, if dual SIM you could use one SIM for calls and text and the other for data.

That's how we run here

Can't be done at all, as @Enlli has pointed out just use a dual sim phone, that is your only option.
