2 visiting US cell phones in London

Is she going to have a U.S based cell phone with international roaming? In that case you have to dial her number normally just like you dial when you are in U.S.

Steve,
I think Jaunty above misread your question. If you and your wife will both be in London with US based cell phones, in order to call her you will have to dial the following: 00 1 812-555-1212. The call will be routed to the US and back to London. You and your wife will both get charged international rates (usually not low).

If your phones use the GSM technology you might be better off buying prepaid SIM cards with local London cell numbers (I think they are called Pay as you go).

I’m not exactly sure bout the rates. But what you just mentioned sounds like an expensive plan. It would probably be better to get cheap SIM cards from U.K once you guys get there.

You can actually make a search for U.K based prepaid SIM cards and get an idea what you might have to pay.

You can call AT&T for furthur clarification regarding the rates.

You’re welcome Jaunty.

Steve,
I believe the fee and rate you mentioned are for just one phone, so in order to use two phones you both would be charged. Here’s the logic behind this: when you call your wife from London you pay your charges for placing an international call to the US. The call is then routed back to the UK and your wife also has to pay charges for receiving the call to the UK. This is how international roaming works. If you would be in the UK and your wife at home in the US then only you would pay for calling or receiving calls. So, unless you have some special family plan from AT&T I think you’ll both incur these fees. It wouldn’t hurt to call AT&T to make sure.
