Customer service need to migrate your number to the new contract

I'll ask our O2 account adviser @O2Lisa if she can help you in the morning

If your old sim fits the new phone then just use that.

The sim has nothing to do with any change of tariff as this is done on O2's system.

All the contract is on the new number plus the old contract number runs out Wednesday that is why I wanted to swap it abs keep the old number

@Mark81 

Even if your contract runs out Wednesday, it doesn't mean you lose the number. If you did nothing, the contract would continue to roll on a monthly basis.

This is why I said, if the old sim fits the new phone you could use that.

However, if your new phone is 5G and you are in a 5G area, the new sim would also be 5G, so to keep the number you would just need to do a sim swap from your old sim.

The way I understood it was that there were two contracts running side by side?
That's why I suggested that O2Lisa could assist in the migration thus ending the first contract
