This guide is for people travelling to Sudan for work, humanitarian assignments or to see family. As of October 2026, Horizon's Sudan eSIM plans name one partner network, Zain, with 3G/4G where available, and the page lists two plans: 3 GB for 15 days and 10 GB for 30 days. The eSIM is data-only and sits beside your own SIM. Read your government's travel advice first, then install the eSIM at home over Wi-Fi and switch the line on once you are in Sudan.
Before you go: official travel advice
Read your own government's official travel advice for Sudan before you make plans, and check it again shortly before you leave, because it can change quickly. The UK government's Sudan travel advice is one example; your own foreign ministry publishes its own. If you travel for an employer or an aid organisation, follow its security and communication plan too. A data plan replaces neither.
The network the Sudan plans name
Horizon's Sudan page names Zain as the partner network, listed with 3G/4G where available. It is not listed with 5G. A badge describes what the network supports, not what a particular district, road or town will give you; which generation your phone shows depends on the device, the location and local conditions. Reception may vary by area, and mobile networks in Sudan can be disrupted. Keep essential documents, contacts and maps on the phone so they open without a connection.
The Sudan data plans
As of October 2026, the page lists these plans:
| Data | Validity |
|---|---|
| 3 GB | 15 days |
| 10 GB | 30 days |
Current prices are on the destination page, because they follow the live catalogue.
The 3 GB plan suits a visit of up to two weeks built on messages, email and maps. A family stay of several weeks, or work with documents, video meetings or a laptop on your hotspot, points to the 10 GB plan for 30 days. For a longer stay, a top-up adds a plan to the eSIM already on your phone, so there is no new QR code to scan; the top-up page explains how it works.
Set it up before you travel
Check that your phone supports eSIM on the supported devices page, and that it is not locked to your home carrier. Install the eSIM at home over Wi-Fi with how to install an eSIM, which covers iPhone and Android. Your installation details are in My eSIMs. Name the line clearly, such as "Sudan data", and keep it off until you arrive.
Save the QR code and installation instructions securely, somewhere you can access without this phone. Keep the eSIM installed. If you delete it or change phones, contact support before trying to reinstall; reuse of the QR code is not guaranteed.
Validity does not start until your eSIM first connects to a supported mobile network at your destination. Installing the eSIM does not start its validity.
Arriving in Sudan
Use the arrival point written in your confirmed travel documents, and share it with the local contact who will meet you. Before you leave, save that contact, the first address and entrance, and the meeting instructions offline, and ask the contact to confirm them shortly before departure. Once you are in Sudan:
- Turn the Horizon line on.
- Choose it as the line for mobile data.
- Turn on data roaming for the Horizon line only.
- Keep mobile data off on your home SIM, unless you accept your home operator's charges.
Hotspot, calls and your own number
Hotspot sharing is free on every Horizon plan. A laptop on your hotspot uses the same data allowance as the phone, so count document uploads and video meetings in your estimate.
There is no Sudanese number on these plans. Your home SIM can stay in the phone with your usual number; whether it can make calls or receive texts in Sudan, and what that costs, is up to your home operator. If your family, host or organisation coordinates through a local number, agree on that before you travel.
Moving between cities
Travel between cities usually follows arrangements made by a host, an employer or an organiser. Long roads are where reception is most likely to change or drop, so keep each stop's contact, meeting point and next instruction in its own offline note.
Sudan and South Sudan are separate countries. A Sudan plan covers Sudan only, and South Sudan has its own South Sudan eSIM page.
Short answers
Which network do the Sudan plans name? Zain, with 3G/4G where available.
Which plans are on sale? As of October 2026, 3 GB for 15 days and 10 GB for 30 days.
Does the plan work in South Sudan? No. South Sudan is a separate country, and the plan covers Sudan only.
Can I install the eSIM before I travel? Yes. Install it at home over Wi-Fi and keep the line off until you arrive. Installing the eSIM does not start its validity.
Do I get a local phone number? No. The plans are data-only, so internet calls and messaging apps use the data allowance.
