Aruba is an island that attracts a lot of tourists who generate international voice traffic there. If you locate GSM gateways there, you will be able to make good money off the difference in the cost of a minute of international and local calls. But keep in mind that for earning on termination you will need a high-quality and stable Internet.
The Internet services market is well developed in Aruba. The Internet penetration rate has reached 78% (more than 11.5 thousand of users). Access to the Global Network is represented mainly by cable technology and ADSL. At the same time, the local Internet is considered quite stable, in comparison with other countries in the region. The average speed on the island is quite high - 10.4 Mbit/s, this is enough for smooth performance of voip gateway systems and effective termination of traffic.
As for the Internet service providers, monopoly has been virtually established in Aruba market. The main player in the local sector of Internet services is Setar, which is also a cellular operator. Because of the monopoly on the island, tariffs for Internet connection are quite high there.
Since Setar also provides cellular services at the same time, we recommend that you hide Internet traffic from the provider. To do this, you can use SBO traffic optimization module from GoAntiFraud, with the connection of Raspberry Pi3. The module will allow you to mask traffic from the ISP and completely hide your activity on the network. Thus, you will ensure safety for yourself and your business and will be able to terminate effectively.
