Will my cell phone work in Curaçao?

Curaçao's cell phone network is on par with those in the US and Europe and most international providers have roaming contracts with local providers. If you choose to use roaming in Curaçao be sure to check with your provider if roaming is available with your cellular package. 

If you stay in Curaçao for longer than a few days or a week, it might be worth buying a local prepaid sim with a data bundle. These generally only work with sim-unlocked phones. Especially in downtown Willemstad, you'll find many open wifi networks.
