This is fantastic information and I'm very pleased to hear it. I just got back from Panama City and Barranquilla, Colombia. I have a Nokia E71X under an AT&T plan. I called AT&T before I left and asked if they could unlock my phone. As long as I was a customer with a plan, they had no problem in doing so. So, before I left, my phone was unlocked. Fast forward to Colombia. My girl takes me to a local Comcel office and asks for a SIM card. They take her information, hand me the chip and I hand them 2000 pesos ($1). I now have a phone number in Colombia. The number will not expire but the minutes expire in 30 days. In order to recharge the phone, you can walk in to just about anyplace that has a Comcel sign outside and they will take down your phone number and recharge it with whatever denomination you want. I did 20,000 pesos ($10). I'm sure I have several minutes left over. Unfortunately I won't be back in time to use them. But, I'll just recharge when I get there. One other thing, if you are going to communicate with someone in particular, make sure you use the same network as they use. If they have another network, your calls are more expensive. Comcel and Movistar are the most commonly used networks.
It is SOOOO convenient to have a local phone number while travelling in a different country. My girl has a very demanding job so, she worked quite a bit while I was there. But, with the convenience of a local number we were able to communicate quite a bit. But, Colombia sucks so don't come here.
