US cellphones will work in Aruba. However please keep in mind that if you retain your own US SIM card you may incur considerable roaming fees from your US cellphone company, you should call to see if they offer coverage in Aruba and what it would cost. Consider renting a cell phone or SIM card to use with your own cellphone if your cellphone company does not offer coverage in Aruba. Please also keep in mind that the voltage in Aruba can be as high as 127 volts, so you would need to make sure that your charger can handle this voltage. There are no area codes in Aruba, so just dial the phone number directly without any prefixes. To call the United States from Aruba dial "00" (international prefix to dial outside of Aruba), then dial "1" (international code for the U.S.). and then the area code and phone number you wish to connect to.

As someone deeply involved in telecommunications and travel technology, I've navigated the intricacies of using cellphones abroad extensively. From my experience and expertise, I can affirm that US cellphones are compatible with Aruba's network infrastructure, largely due to Aruba's use of GSM technology, which aligns with the majority of US carriers' networks. This compatibility ensures that most US phones will function seamlessly in Aruba.
However, the critical aspect to consider is the potential for substantial roaming fees if you retain your US SIM card while using your phone abroad. These fees can accrue quickly and significantly impact your phone bill. To mitigate this, reaching out to your US cellphone provider beforehand is crucial. Inquire about their coverage in Aruba and the associated costs for using your phone on the island. Some providers offer international plans that might reduce roaming charges, so it's wise to explore these options.
Another viable strategy, if your provider doesn't offer suitable coverage or affordable international plans, is to rent a cellphone or SIM card upon arrival in Aruba. This alternative allows you to use your own device while avoiding excessive charges from your home carrier.
Additionally, the difference in voltage standards between the US and Aruba is noteworthy. Aruba's voltage can reach up to 127 volts, necessitating compatibility checks for your charger. Ensure that your charger supports this voltage range to prevent damage or malfunction.
Aruba operates without area codes, simplifying the dialing process. To make a call within Aruba, simply dial the phone number directly without any prefixes. Conversely, to place an international call from Aruba to the United States, dial "00" (the international prefix), followed by "1" (the US international code), and then the area code and phone number you wish to reach.
For further details regarding Aruba's telecommunication specifics, I recommend referring to reliable sources or the local telecommunications authority. This information provides a foundational understanding, but it's always beneficial to stay updated on any changes or specific regulations.
