Flag of Saint Helena

Basics Edit

Saint Helena is an island and is part of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha in the South Atlantic about halfway between Africa and South America. Even though it belongs to the same territory as Ascension Island, the mobile networks are separate and hence merits a separate article.

It's not considered part of EU, so EU roaming caps don't apply and providers charge a very high price for roaming. It has roaming agreements with very few providers so far, even not all providers from the UK. That's why it will be much more likely that your device won't roam there at all. The island has no submarine cable link and all the communications go through a relatively narrow band satellite channel. So expect low speeds (even on 4G/LTE), high latency and very high prices. The first and so far only network operator started in 2015:

  • Sure South Atlantic Ltd.

It operates a 2G/GSM/EDGE on 900 MHz and LTE on 1800 MHz (band 3). Note that there is no 3G/UMTS, so if you want data, you need a phone that supports LTE band 3 or you'll be limited to slow 2G/EDGE speeds.

Sure Edit

Sure telecom

Sure by Sure South Atlantic Ltd. is a triple player offering landline, TV cable and mobile broadband services on the island. In 2015 it started the only network covering 95% of the island in 2G and 4G/LTE: coverage map (Note that red unintuitively means "very good signal")
