Can someone explain the process of using an unlocked phone w/ SIM card? We use our iphones for wireless only, and this year have the need to provide an emergency number to family at home. Trying to decide between renting a phone (which we have done before), or trying this unlocked phone/SIM route. Am I correct in understanding that we can buy a cheap (i.e., $20-25 @ Walmart) unlocked GSM phone, go to Digicel at the airport and purchase a SIM card for around $20? If that's the case, assume they will show how to insert and will also provide us with an Aruban phone number? I understand we can add a few minutes every 5-6 months to keep it active and use annually going forward.
For those of you that have done this, is it this simple? Any caveats I need to consider? We arrive on Sunday 3:30 (yup - this weekend - 5 days!), will Digicel be open? Appreciate your feedback.
