Mobile Phone Provider While In Curacao and Saint Martin

Question

Is there a provider that I can use in Curacao and Satin Martin? Verizon claims that they have coverage in Curacao on CDMA but thats not true. Do any of the providers support the European GSM frequencies? [I have an unlocked Euro dual band phone]

I would prefer if:

1. It was inexpensive
2. Could call the US cheaply.

Answer 1

UTS (previously Setel) looks like an option - single prepaid account for Curaçao, St. Maarten / French St. Martin, and others.

It appears that Curaçao at least uses GSM 900 for 2G (like Europe), and other sources say St Martin do as well.

No idea on the call costs.
