Sudan

About connectivity in Sudan

Sudan uses 230V/50Hz with Type C and Type D outlets — a mix reflecting layered British colonial-era wiring (Type D from the Anglo-Egyptian Condominium era) and modern European-standard installations. The phone jack is RJ-11. Sudatel (Sudan Telecommunications Company), the state-controlled fixed-line operator, holds historical market position. The mobile market is contested between Zain Sudan, MTN Sudan, and Sudani (the Sudatel mobile subsidiary). The post-April-2023 Sudan civil war has substantially disrupted telecom infrastructure and operations across the country.

Sudanese commercial Internet emerged in 1997 through Sudatel as the sole licensed ISP through the early 2000s. Per-minute metered dial-up dominated the late 1990s and early 2000s. The pre-2011 secession of South Sudan and subsequent infrastructure separation reshaped the Sudanese telecom landscape. Mobile data has driven essentially all recent Internet-access growth; the 2018-2019 revolution and the 2021 military coup were accompanied by extended government-imposed Internet shutdowns. The April 2023 civil war has fragmented connectivity across the country, with Khartoum-area infrastructure severely damaged.

Sudatel cardphone deployment was modest. The Sudanese prepaid international calling-card market through the 2000s and 2010s served the substantial Sudanese outbound diaspora — concentrated in the UAE and Saudi Arabia (Sudanese migrant labor populations across the Gulf states), Egypt (the historic Cairo-area community, with substantially expanded numbers post-2023 due to displacement), the United States (the post-2003 Darfur conflict refugee resettlement, with communities in Iowa, Minnesota, and the DC Metropolitan Area), the United Kingdom, and Australia.

Tempest Telecom served Sudan through dial-up POPs in Khartoum. Iridium satphones served the very substantial NGO and humanitarian customer base across the recurring conflict zones (the 2003-onward Darfur crisis, the South Sudan civil war that preceded 2011 independence, the post-2023 nationwide civil war), broadcast journalists covering these conflicts, archaeological-research operators across the country's Nubian heritage sites (Meroë, Naqa), and pre-secession oil-and-gas operations across the south.

Modern Sudan has severely degraded telecom infrastructure due to the ongoing 2023 civil war. Pre-conflict 4G LTE coverage in major cities is partially operational depending on territory.

Tempest's services across Sudan, 1997–2012

Tempest Telecommunications operated international connectivity services in Sudan between 1997 and 2012 under a unified prepaid account that absorbed multiple service types onto a single customer credential. Customers in Sudan drew from the same balance for pre-paid international voice calling, RADIUS-authenticated dial-up Internet roaming, metered Wi-Fi hotspot access, Iridium and Thuraya satellite voice, and Inmarsat BGAN and Thuraya data terminals. An attempted kiosk-payment federation (PATN, 1998) extended the same architecture to public Internet terminals but failed to reach scale.

Both Iridium (global LEO) and Thuraya (regional GEO) satellite voice were available in Sudan from approximately 2001, alongside global BGAN data from late 2005.
