I tried a SIM Card from Claro on my last trip but my shameful grasp of the language and the agent not speaking English didn't help the situation - but at least it made for a very entertaining situation :P
Any help would be greatly appreciated! Off to study my spanish!
I'm assuming that you have unlocked your BB ... you can purchase a prepaid SIM card through various companies online and it should be able to work all over the world ... I would be sure to google several companies and check their respective rates before I bought any though ...
