At the end of December I bought a Claro phone for RD$745 (no questions asked) with a SIM that works in my unlocked Nokia. It can send me texts, but does not receive my texts. At the end of March I tried to buy a SIM for a similar phone that I brought for a friend. In the same store, they wanted RD$350 and a bunch of contact information for her including cedula number. I didn?t have the information so we ended up getting the SIM somewhere else (Orange), under the same terms. That worked out to her advantage because now she can receive texts. I think it might be cheaper also.
