How to revert to previous sim card

[David25]

I requested a sim swap but it turns out that the new sim is pay monthly and so doesn't work. I would like O2 to revert my number to the old sim card.

How do I do it?

You need to get another PAYG sim and do a sim swap Guide: Sim Swap: a mini guide 2017 update 

Order any sim from here https://www.o2.co.uk/shop/sim-cards/pay-as-you-go

I already have a functioning sim so I do not need another sim. And I cannot do a swap online because it requires you to receive a text which I cannot

You need a new payg sim, you cannot revert back to one already used and cancelled.

A monthly sim will still receive texts when activated.

Thanks for the quick reply. Unfortunately in our case no texts are received.

You need to contact O2 to complete the swap.
