Apparently all of the phones I brought with me from the US are dual-band or triband phones, which will not work with personal, movistar, or claro services/sim cards. I need a quadband phone a.k.a. movíl cuatribanda. Anyone have an extra cuatribanda that they could part with for a small price? I am not looking for anything fancy. I just need to be able to make and receive calls and texts. Thanks.
