I will be traveling to the Cayman Islands next year from the US where I use a pre-paid T-Mobile (unlocked, original Motorola RAZR) phone. From the answer to this question about T-Mobile in the US Virgin Islands it appears from the T-Mobile International Roaming Charges I could roam the Caymans for $2.39/minute.
What cheaper options for voice/text would be available for me in the Cayman Islands?
