Aruba coverage

What the Aruba numbers mean

Two numbers matter and only one of them is the one every seller quotes. The typical speed, 46 Mbps, tells you what a good moment looks like.

The tenth percentile, 11 Mbps, is the one that matters. It is the speed in the worst tenth of the day, when the cell above the station is full and everybody around you is on it too. A country with a high median and a low floor is a country that works beautifully right up until the moment you actually need it.

If the trip depends on video calls or tethering, plan around the busy figure rather than the typical one.

What happens in Aruba when the network is busy

Congestion is not a fault, it is a Tuesday evening. The question is what your eSIM can do about it, and for most travel eSIMs the answer is nothing: one wholesale agreement per country, one network, and no way out except buying a second eSIM from somebody else while standing in the street.

Here, Orbislo traffic runs over Setar and Digicel. When the network you are on degrades we move you to another one, mid trip, without you asking, and tell you afterwards rather than interrupting you at the time.

Mobile operators in Aruba

• SETAR: SETAR, founded in 1986, is Aruba's national telecommunications company. It held a monopoly on telecom services until its privatisation in 2003, after which the Aruban government still owned 100 percent of its shares.
• SETAR, network history: SETAR introduced GSM in 2001, international roaming in 2002, HSPA+ in 2011 and LTE in 2014. In 2022 it upgraded its mobile switching centre and radio access network to newer technology.
• SETAR, 4.5G Pro: Nokia runs SETAR's island wide 4.5G Pro network, and SETAR completed a network modernisation with Nokia in June 2019 that sharply improved its downlink and uplink speed rankings.

Older networks in Aruba

• SETAR is switching off its 2G network from 1 August 2026. Old phones, alarm systems and payment terminals that work only on 2G stop working, and SETAR expects to switch off 3G in 2029.

5G in Aruba

• On 19 December 2019 SETAR signed an end to end 5G deal with Nokia, covering upgraded radio access, a modernised core and massive MIMO 5G at the first selected sites. It was Nokia's first end to end 5G deal in Latin America.

Network notes for Aruba

• In June 2026 SETAR launched an LTE Cat M1 network, a low power layer on its 4G network for connected devices with better indoor coverage. Its first product on the network was a fleet management service.
• Aruba's international links run over submarine fibre: the Pan American cable reached Aruba in 1998 with a link to St. Croix, the Alonso de Ojeda cable connects it to Curaçao, and SETAR joined the Americas II cable in 2000.
• A mobile network concession in Aruba carries a one time fee of 7.2 million florins, plus an annual charge of 98,000 florins per megahertz held in the uplink bands, under the national telecommunications rights decree.
• Aruba's telecommunications directorate, DTZ, manages the radio spectrum, assigns frequencies and monitors their use, and acts as supervisor and expert for the whole field of wired and wireless electronic communications.
