You probably don't need one for this trip but if you plan on returning you might want to think about it. I keep my Jamaican SIM active buy adding a small amount credits avery couple of months. The minutes and the phone are there for me to use when I return. Even When I'm home I make any calls to Jamaica on that phone. This way I have no need to give out my personal number and can keep phone books separate. I actually have 3 sims\numbers....personal, work and Jamaican.
