Call waiting iPhone 5

[Anonymous]

I'm on a 12 month Simplicity pay monthly tariff.

While looking around in Settings/Phone, I saw a setting for Call Waiting, which I switched on (it was off).

I tried it out and it worked, it basicially showed me the number of the person trying to get through and I heard the beep in the earpiece.

I was wondering if there is any charge for using the Call Waiting service on the tarriff I'm on.

Thanks in advance

I'm pretty sure it's all done hardware side:)

so no charges:)

Got me thinking now.

I've never seen a charge.

It's turned on with my iPhone 5 anyway and I'm on payg

Thanks everyone for the help, its much appreciated.

I've looked on my O2 and so far there's no recent charges, so I expect its a free service.

Thanks again.
