UNDERSTANDING COSTS
International calls to Sudan are among the pricier routes in Africa. Understanding the factors behind this helps explain why rates are higher — and why finding a reliable provider matters even more.
Since the civil war began in April 2023, Sudan's communications infrastructure has been severely impacted by destroyed telecom towers, damaged data centres, and ongoing attacks on critical infrastructure. All three major operators — Zain, MTN, and Sudatel — have lost control of parts of their networks, driving up termination costs for international routes.
Sudan's electrical grid was already fragile before the conflict, with only about 40% of the population connected to mains power. Fuel shortages and targeted strikes on power infrastructure mean telecom base stations frequently lose power, creating intermittent service and higher costs to maintain route availability.
Sudan's international bandwidth depends heavily on submarine cables reaching Port Sudan on the Red Sea coast. With few redundant routes and conflict threatening coastal infrastructure, international voice termination carries a premium. Satellite services remain cost-prohibitive for most of the population.
The Internet Society rates Sudan's internet resilience as low even by African standards. A small number of upstream providers, minimal peering infrastructure, and a concentrated market with just three mobile operators create bottlenecks that translate into higher costs for every international minute.

CALLING OPTIONS
Staying in touch with Sudan is challenging right now. Here's a realistic look at the options people use — and where each one falls short.
Traditional Carrier (AT&T, T-Mobile, etc.)
Most US and European carriers charge steep per-minute rates for calls to Sudan. Many plans exclude Sudan from international bundles entirely, resulting in bill shock for regular callers.
WhatsApp / Messaging Apps
WhatsApp voice and video calls were suspended by Sudan's telecom regulator (TPRA) in July 2025, citing security concerns. Even before the ban, internet blackouts and network damage made app-based calls extremely unreliable across much of the country.
International Calling Cards
Calling cards were once popular for diaspora communities, but rates to Sudan are often opaque with connection fees and maintenance charges. Card quality varies widely, and many have left the market.
Browser-Based Calling (Sayfone)
Browser-based calling routes through direct international voice networks rather than relying on Sudan's internet infrastructure. This means calls can still connect to Sudanese mobile and landline numbers even when internet-based apps fail.
Bar lengths reflect relative cost tiers for each option — not survey percentages.

APP LIMITATIONS
Sudan is one of the most difficult countries in the world for internet-dependent communication. Conflict, government restrictions, and infrastructure collapse make app-based calling deeply unreliable.
Sayfone routes calls through international voice networks that terminate on Sudan's mobile and landline infrastructure — not through the internet. When WhatsApp is blocked and data networks are down, direct dialing through phone networks remains the most reliable path.
The problem
For millions of Sudanese and their diaspora, the inability to use WhatsApp and similar apps isn't a minor inconvenience — it's a crisis. Direct voice calling over phone networks remains the most reliable way to reach people in Sudan.
In July 2025, Sudan's Telecommunications and Post Regulatory Authority (TPRA) announced that WhatsApp voice and video calls would be suspended indefinitely, citing security concerns. Text messaging remains operational, but the voice features millions relied on are blocked.
A nationwide telecommunications shutdown in February 2024 left nearly 30 million Sudanese without internet or phone service for over a month. Large areas of Darfur, Khartoum, and the Kordofans remain frequently disconnected from network providers.
All three of Sudan's mobile network operators have lost control of portions of their infrastructure. Damaged base stations, stolen equipment, and destroyed data centres mean even basic mobile data for apps is unavailable in many areas.
Without reliable electricity, telecom towers go offline for extended periods. Backup generators require fuel deliveries that are frequently impossible in conflict zones. Even when data service briefly returns, quality is too poor for stable voice-over-IP calls.

TIPS & ETIQUETTE
Timing, etiquette, and a few practical considerations can make your calls to Sudan more successful — especially given the current connectivity challenges.

No daylight saving time

4 PM in Sudan
EST (UTC-5) → CAT (UTC+2)
When it's 9 AM in London

GMT (UTC+0) → CAT (UTC+2)
Try Multiple Times
Due to intermittent network availability across Sudan, your first attempt may not connect. Try again after 15–30 minutes — network windows open and close unpredictably in conflict-affected areas.
Confirm the Active Number
Many Sudanese have had to change SIM cards or operators due to network damage. Confirm the current working number via text message or through mutual contacts before calling.
Keep Calls Concise
Network connections in Sudan can drop unexpectedly. Cover the most important topics first in case the call is interrupted. Having a brief agenda helps make the most of your minutes.
Use +249 Format from Mobile
Always dial the full international format: +249 followed by the 9-digit number (without the leading 0). From a US landline, use 011 + 249 + number.
Greetings Matter
Begin with 'As-salamu alaykum' (peace be upon you) — the standard greeting. Expect warm, extended pleasantries before getting to business. Jumping straight to the topic is considered impolite.
Arabic is the Primary Language
Arabic is the official language and the default for phone calls. English is understood in some business and academic circles but should not be assumed. Consider having key phrases ready if you don't speak Arabic.
Respect Prayer Times
Five daily prayers structure the Sudanese day. Avoid calling during prayer times, especially the Friday noon prayer (Jumu'ah). Most people will not answer calls during these periods.
Patience with Connectivity
Your Sudanese contacts are likely dealing with unreliable power and network access. If they cannot talk long or need to call back, it reflects infrastructure challenges — not disinterest.
POPULAR DESTINATIONS
These are the cities people call most frequently in Sudan. Each has its own area code and connectivity profile shaped by the ongoing conflict.
Khartoum
Khartoum sits at the confluence of the Blue and White Nile rivers. As Sudan's capital and largest city, it is the most frequently called destination. Connectivity has been severely affected by the civil war, with major blackouts and infrastructure damage since 2023.
Best time to call: 4 PM – 9 PM CAT (when network availability tends to be more stable)

Omdurman
Omdurman is part of greater Khartoum and is Sudan's most populous city. It is a cultural and commercial centre. Network service has been disrupted during military operations, particularly in 2023 and 2024.
Best time to call: 4 PM – 9 PM CAT

Port Sudan
Port Sudan is Sudan's main seaport and has become a de facto administrative centre since the conflict. Telecom infrastructure in the east has been partially rebuilt, making connectivity somewhat more reliable here than in western regions.
Best time to call: 8 AM – 8 PM CAT (relatively better network availability)

Kassala
Kassala is an eastern city near the Eritrean border. It has seen some infrastructure recovery since the conflict began. Mobile networks operate more consistently here compared to western and central Sudan.
Best time to call: 4 PM – 8 PM CAT

Nyala
Nyala is the largest city in Darfur and has been heavily affected by the conflict. Connectivity in the Darfur region is extremely limited, with satellite services sometimes being the only option. Reaching contacts here may require multiple attempts.
Best time to call: Unpredictable — try multiple times throughout the day
