Your cell phone will work here but check on roaming charges. GSM phones will work in Aruba only if you have an unlocked SIM phone. Contact your local service provider before traveling to Aruba.

It is possible to rent a cell phone or purchase a SIM card right at the airport in the arrivals terminal at Setar or Digicel . A deposit and proper identification is required when renting a phone.
Repeat visitors may consider the purchase of an inexpensive cell phone instead of renting one.
Teleshops are also located in the hotel area.
