Will a second SIM replace my existing mobile number?

[Patrick_Jane]

Hi,

I have an O2 PAYM contract. I use the phone for work and personal use and I decided to buy a second SIM so I could have two numbers, one for personal use and one as a work number. 

After I ordered the second SIM something popped into my head. Some of the wording during the online ordering process (I was logged in to MyO2 at the time) suggested the number on the second SIM would replace my existing number and wouldn't be an additional number. In other words, I'd lose my existing number and it would be replaced by the number on the new SIM. 

This probably sounds really dumb but does anyone know if that could happen? I've tried calling O2 but can't through (yet).

Many thanks in advance.

It depends how you ordered.

If you just chose a new contract it will be an additional number, however, if you chose an upgrade, it will be a replacement.

What do your confirmation emails say?

Thanks for the quick reply!

The confirmation emails don't actually mention whether this is a new contract or not. The deal I got as a "USWITCH Special". I was logged into MyO2 when I bought the deal via USwitch and the order system obviously recognised that because it brought up my existing account details as I placed the order.

The confirmation email I've got mentions a "new SIM" and shows the number associated with that new SIM. During the ordering process I had two options: "Upgrade" or "Get new number". I chose "Get new number" but there was something in the wording that suggested the new number would replace my old number. The confirmation emails mention a "new number" but there's no mention of upgrades or new contracts.

I didn't want to activate the new SIM and find it affected my existing number (which is still working BTW).

Many thanks

Difficult to say tbh but if you check your MyO2 it should indicate if you have a new contract by showing both your old and new one http://www.o2.co.uk/myo2
