Stay Connected in Saotomeandprincipe
Network coverage, costs, and options
Connectivity Overview
Saotome and Príncipe's telecommunications infrastructure is still developing, with connectivity primarily concentrated in the capital Saotome city and larger towns. The two main islands have basic 3G and 4G coverage through local carriers, but expect slower speeds and occasional service gaps compared to major international destinations. Internet cafes remain common for backup connectivity. Mobile data is the primary way visitors stay connected, as WiFi availability is limited outside hotels and some restaurants. The small tourism infrastructure means fewer English-speaking staff at telecom shops, making pre-arrival planning especially important. While connectivity has improved significantly in recent years, it's wise to download offline maps and essential information before traveling to remote areas of either island.

We recommend Airalo for peace of mind. Buy your eSIM now and activate it when you arrive—no hunting for SIM card shops, no language barriers, no connection problems. Just turn it on and you're immediately connected in Saotomeandprincipe.
Network Coverage & Speed
The telecommunications market in Saotome and Príncipe is dominated by two main carriers: CST (Companhia Santomense de Telecomunicações) and Unitel STP. CST provides the most complete coverage across both islands, with 3G networks covering most populated areas and expanding 4G coverage in Saotome city and Príncipe town. Unitel STP offers competitive 4G speeds in urban areas but has more limited rural coverage. Expect download speeds of 5-20 Mbps in cities, dropping to 1-5 Mbps in rural areas. Coverage can be spotty along coastal roads and in mountainous regions, particularly on Príncipe island. The infrastructure relies heavily on satellite connections, which can cause latency issues for video calls. Network congestion is common during peak evening hours. International roaming agreements exist with major global carriers, but costs are typically high due to the country's remote location and limited infrastructure partnerships.
How to Stay Connected
eSIM
eSIM technology is relatively new to Saotome and Príncipe, with limited local carrier support, but international eSIM providers like Airalo offer coverage through regional partnerships. This is actually advantageous for travelers, as it bypasses the challenges of finding English-speaking staff at local telecom shops and ensures immediate connectivity upon arrival. eSIM plans typically cost $15-30 for 1-3GB packages lasting 7-30 days, which is more expensive per GB than local options but includes the convenience factor. The main advantage is avoiding the uncertainty of SIM availability at the small international airport and having backup connectivity if local networks experience issues. However, eSIM speeds may be slightly slower than direct local carrier connections, and customer support operates from international time zones rather than locally.
Local SIM Card
Local SIM cards are available from CST and Unitel STP shops in Saotome city, at the airport (though not always staffed), and from some hotels. You'll need your passport for registration, and the process can take 15-30 minutes with potential language barriers. Prepaid plans start around $5-10 for basic packages with 1-2GB data, making them significantly cheaper than eSIM options. Top-up cards are sold at small shops throughout the islands, but availability decreases outside main towns. CST generally offers better coverage for island-wide travel, while Unitel STP may have faster speeds in urban areas. The main challenges include limited English support, potential SIM shortages during peak tourist seasons, and the risk of getting a faulty SIM with no immediate recourse. Activation can sometimes take several hours, and troubleshooting technical issues requires visiting physical stores.
Comparison
Local SIMs offer the best value at roughly half the cost of eSIM plans, but require time, local knowledge, and patience to obtain and activate. eSIM provides immediate, hassle-free connectivity that's ideal for short visits, while international roaming costs 3-5x more than either option. For stays under two weeks, eSIM's convenience typically outweighs the cost difference. Local SIMs make financial sense for budget travelers staying longer than a month, but factor in the time cost and potential frustration of setup.
Our Recommendations
First-time visitors: Go with an eSIM from Airalo before you travel. You'll land with working internet to call taxis, translate Portuguese, and navigate without the stress of finding a SIM shop that may or may not have English-speaking staff. The extra $10-15 cost is worth avoiding potential airport delays and ensuring immediate connectivity. Budget travelers: If you're on an extremely tight budget and staying 2+ weeks, local SIMs save money long-term. However, most budget travelers find the time saved and reduced stress of eSIM worth the modest premium. Long-term stays (1+ months): Local SIM cards become cost-effective for extended stays. Start with an eSIM for immediate arrival connectivity, then switch to a local SIM once settled. Business travelers: eSIM is your only practical option - you can't afford connectivity delays or language barriers when you need reliable internet for work immediately upon landing.
Our Top Pick: Airalo
For convenience, price, and safety, we recommend Airalo. Purchase your eSIM before your trip and activate it upon arrival—you'll have instant connectivity without the hassle of finding a local shop, dealing with language barriers, or risking being offline when you first arrive. It's the smart, safe choice for staying connected in Saotomeandprincipe.
