Eritrea eSIM
Eritrea has to be planned as an offline trip from the outset. Asmara is a highland city famous for its modernist architecture, while Massawa sits on the Red Sea at the bottom of a long, winding descent from the escarpment. Travelling outside Asmara requires a paper permit arranged in advance rather than anything online, and internet access for visitors is very restricted. Anyone going should expect to be in touch with home only in occasional windows.

How much data you actually need
Plan without assuming data through the day. Work from offline maps and documents saved to the device, and agree fixed check-in windows with people at home instead of expecting to be continuously reachable while you are in the country.
When you land
Asmara International (ASM) is the main gateway and sees only a handful of flights a week, with Massawa (MSW) and Assab (ASA) as the other airports. By sea, the port of Massawa is where boats leave for the Dahlak archipelago. Land borders open and close depending on the regional situation, so check with an embassy or your operator beforehand, and carry every document as a paper copy.
Where coverage changes
In practice you should treat connectivity in Eritrea as limited everywhere. Asmara has the most options but they are neither fast nor consistent, and once you head out towards Keren, Massawa, the Qohaito plateau, the Dahlak islands or the Danakil in the south, assume there is nothing at all. Save maps, tickets and your travel permit to the device and carry printed copies of all of them as well.
Cities travellers ask about
- Asmara — Highland capital, World Heritage listed for its modernist architecture.
- Massawa — Red Sea port, hot and humid, with old buildings scarred by war.
- Keren — Northern hill town with a weekly market drawing people from across the region.
- Dahlak Archipelago — Red Sea islands reached by boat from Massawa; entirely self-sufficient travel.
Apps to install before you fly
- An offline map app such as Maps.me or OsmAnd, downloaded before you travel
- An offline phrasebook with Tigrinya vocabulary saved to the device
- An offline document folder holding your travel permit and every ticket

FAQ
Can I buy an eSIM for Eritrea from eSIMonline?+
No. We do not offer a plan for Eritrea, and this page is travel context only. Plan the trip on the basis that you will not have your own data while you are in the country. If your route continues into other countries, message us on LINE at https://lin.ee/skDPoNx or email esimonline.asia@gmail.com and we can tell you what exists for those next destinations instead.
Do I really need a permit to leave Asmara?+
Yes. Travel beyond the Asmara area requires a permit arranged in advance, and it is a paper document you show at checkpoints along the road, not something you file online. Ask your operator or your hotel to start the process on your first day, allow several days for it, and photograph the permit so you also have a copy on the phone.
What should I prepare before entering the country?+
Make everything work offline. Download maps of Asmara and the road down to Massawa, save your accommodation address, contact numbers and every ticket to the device, and carry printed copies of the important documents. Bring enough cash, since foreign cards are of very limited use, and agree with people at home that you will check in periodically rather than daily.
When does a Eritrea eSIM start counting days?+
Most plans here start when the phone first connects to a network at the destination, so you can install in advance at home and switch it on after landing. Each plan page states its own rule.
Do I have to remove my home SIM?+
No. The eSIM is a second line, so you keep your home number for SMS OTP. Turn off roaming data on the home line and set the eSIM as the data line.
