I have tried them all-whats app, free wi-fi, FB and Google phone. This year being on the island for 5 weeks I stopped at the Texaco gas station in Simpson Bay and bought a SIM card from TelEm. The card is $20 and you get $10 of air time, data etc. I have a local phone # and did a top up for $10 last week. It works great and I emailed the number to family and friends and they are able to phone me at any time. Last year I did the Verizon plan and with limited use I spent $130.00. Very satisfied with my SIM card purchase.
