How do I unlock this old Cingular phone to use abroad?

I would just pick up a cheap GSM phone at your destination. No matter where you're going, there's bound to be a cheap or nearly-free pre-paid phone available. I'm Canadian, and I've done this in the US, Mexico, and in Portugal. I just get the cheapest pre-paid phone possible. Usually $10 or so. Unless there's a reason you want to use the RAZR, there's no reason to take it with you. It might not even have the appropriate local frequencies anyway, depending on where you're going.

It does have the local frequencies and the destination is tourist-y, so I expect extortionist prices for the cheap pre-paid.

The touristy reasoning probably isn't going to actually be true, but regardless, you're going to have to purchase a local "plan," whether its just roaming or you buy a prepaid sim. Perhaps say where you are going so people can offer advice on that.

Perhaps if you mentioned where you will be going someone who has been there might have a clue of the prepaid phone options.

I've unlocked a couple of older Moto GSM phones (a V195 was one as I recall) and it was very easy. http://www.youtube.com/watch?v=Ss08kR0nfGs You need to borrow a SIM card from somebody for a few seconds to enter your unlock code. Thereafter give them back their SIM and get your own from any GSM provider.

Thanks for your content-filled post, Horselover Phattie. The location of my destination is irrelevant. The question is about unlocking a phone.

Different places have different options for pre-paid phones. Maybe someone reading this just got back from where you are planning to go and has an idea of the cost.

The location of my destination is irrelevant. The question is about unlocking a phone. Not so fast. It is important to note that certain GSM phones can be only dual-band or tri-band. They will only work on certain frequencies. The wireless carrier in your destination city might use different frequencies. To be safe, you should look up the http://mobileworldlive.com/maps/ and make sure your phone supports it. There are various models of the Motorala Razr V3 so you need to find out which one you have.
