I'm currently living in POS Trinidad and got myself a local number on digicel. Problem I have is one minute it works fine then the next I can't send text messages or make calls! I've been to the shop and they just tell me to go away and monitor it. My questions are these has anyone had a similar issue with digicel? Is bmobile better? Would I be better with a global sim as although I'm based in Trinidad I contact the uk a lot and fly around the Caribbean a lot as well as returning to the uk? All suggestions and comments welcome.
