South Sudan eSIM Guide

This is South Sudan — the country that became independent from Sudan on 9 July 2011, capital Juba, ISO code SS, dialling code +211, currency the South Sudanese pound, official language English. Sudan is the separate country to the north, capital Khartoum, ISO code SD, dialling code +249. They are two sovereign states with two separate sets of mobile operators and two separate eSIM plan families, and the names are close enough that people buy the wrong one. If you meant Sudan, our Sudan eSIM guide is linked at the top of this page. A South Sudan plan does not work in Sudan, and a Sudan plan does not work in South Sudan.

One network, and only one: MTN South Sudan, MCC-MNC 659-02, declared as 4G. Every South Sudan plan in our catalogue is supplied through the same upstream and lands on that same radio. Zain South Sudan and Digitel exist as real operators in the country, but our eSIM does not roam on either of them, and we are not going to list them as though it did. If your handset shows Zain or Digitel in the operator list, selecting it will leave you with no data.

Because the underlying wholesale roaming into South Sudan is expensive, and there is very little competition for it. Our entry plan is 1 GB for 7 days at roughly US$21, and the largest plan, 20 GB for 30 days, is around US$350. Those are not typos and we are not going to dress them up as a bargain — most countries in our catalogue are a fraction of that per gigabyte. The practical response is not to shop for a cheaper eSIM brand, because they are all buying into the same small set of roaming agreements. It is to buy the smallest plan that covers what you actually need, use wi-fi at the compound, office or hotel for anything heavy, and top up if you run out.

No. We checked our own catalogue rather than a marketing map: South Sudan appears in exactly one place, the South Sudan country plans. No Africa regional plan of ours includes it, no global plan of ours includes it, and no other supplier in our system carries it. This matters more than it sounds. If you are travelling Nairobi to Juba to Kampala on one profile, there is no single plan of ours that covers the middle leg — you need a South Sudan country plan alongside whatever you are using for the rest of the trip. It is also worth checking any regional eSIM you already own for the letters SS specifically, because Africa regional packages frequently leave South Sudan out.

In the larger towns, often. Beyond them, plan for nothing. MTN launched 4G in South Sudan on 3 December 2020 with, in its own words, "over 70 sites in Juba" and a commitment to extend to the rest of the country afterwards — the network grew outward from the capital, and coverage still follows population centres, main roads and the places where there is power. Large parts of the country have no cellular service of any operator, and the rainy season closes roads and knocks out sites. If your movement plan takes you off the main axes, satellite communications are the plan and the eSIM is the thing that works again when you get back to a town.

That is not a verdict a connectivity page should hand you, but the advisories are unambiguous and we will not bury them. The UK Foreign, Commonwealth and Development Office advises against all travel to South Sudan due to the risk of armed violence and criminality, advice last updated 25 August 2026, and states that consular assistance to British nationals is severely limited and that in-person consular assistance is not available. The US State Department has South Sudan at Level 4 — Do Not Travel, most recently reissued on 13 November 2025. Read your own foreign ministry’s current page before you book, and follow your organisation’s security briefing while you are in country.

It has happened, recently and nationally. On 22 January 2025 South Sudan’s National Communication Authority directed internet service providers to block social media for up to 90 days, citing graphic content circulating from the conflict in Sudan; MTN and Zain notified subscribers and the block took effect from midnight. The NCA lifted it on 27 January 2025, five days later. An eSIM gives you no immunity from this — you are on a South Sudanese network and subject to whatever that network is instructed to do. If your work depends on a specific platform, have a second channel agreed in advance, and clear any circumvention tooling with your organisation before you travel rather than improvising it in country.

Less than you think, and deliberately so, because data here is expensive. For a Juba-based posting where the compound or office has wi-fi, 3-5 GB over a month covers maps, messaging, email and coordination. Video calls are what break that budget: an hour a day of video will clear a 10 GB plan inside a fortnight. If you are filing reports, photos or footage from the field, 10-20 GB is the realistic band, and it is worth doing the uploads from wi-fi wherever one exists. There are no unlimited plans for South Sudan in our catalogue, so there is no way to buy your way out of the arithmetic.
