A trip through the Caucasus might centre on Georgia, with Tbilisi and the mountains of Kazbegi or Svaneti, and add Yerevan and Lake Sevan in Armenia and Baku's Old City on the Caspian. That is three countries, three sets of networks and no EU roaming anywhere. The catch for an eSIM is that the three do not sit in the same regional zone.
This guide explains which plans cover which countries, when one eSIM for Georgia, Armenia and Azerbaijan is the simpler choice and when country plans fit better, and what to expect from coverage in the mountains.
Key facts for a Caucasus trip
- One plan for all three: World, with 201 destinations, is the only zone that covers Georgia, Armenia and Azerbaijan
- Regional zones: Europe Extended covers Georgia and Azerbaijan but not Armenia; Middle East covers Armenia but not the other two
- EU roaming: none of the three is in Roam Like at Home
- Emergency numbers: 112 in all three; Armenia also answers on 911
- Embassies: in Tbilisi, Yerevan and Baku
Three neighbours, two regional zones
Georgia, Armenia and Azerbaijan are neighbours, but the plans page groups them differently. Europe Extended, a zone of 56 destinations, includes Georgia and Azerbaijan but not Armenia. The Middle East zone, with 14 destinations, includes Armenia but neither of the others. Only World covers all three on one eSIM.
And a country plan works only in its own country: a Georgia plan does not cover Armenia, and an Armenia plan works only in Armenia. None of the three is in Roam Like at Home either, so an EU SIM pays its operator's roaming rates in all of them, and European tariffs often charge it by the day.
Which crossings you can use overland depends on current border arrangements, so read the travel-safety pages before you plan the route.
Coverage in the mountains
Coverage is good in Tbilisi, Yerevan and Baku and holds along the main routes. In the mountains it gets patchy: on the hike from Mestia to Ushguli in Svaneti, in the deep valleys on the way to Tatev in southern Armenia and on the road up to Khinalug in Azerbaijan, the signal can drop. Download offline maps before you set off and keep your accommodation's details saved on the phone.
Which plan fits your trip
If your trip takes in all three countries, World plans put them on one eSIM. For Georgia and Azerbaijan only, Europe Extended plans cover both. If most of your days are in one country, a country plan may fit better, for example for Georgia, with a second plan for a short visit next door.
Telcomia's standard plans are data only: no local number or SMS, with calls through apps such as WhatsApp. The plan details show the Activation line, which gives the start of the validity period, plus the duration, the data and whether sharing the connection is allowed.
Before you leave
- Install the eSIM at home on Wi-Fi and keep it until the trip ends; some eSIMs can be installed only once.
- Make the eSIM your mobile data line, with data roaming on for it and off for your home line.
- Check that your plan covers every country on your route.
- Download offline maps for the mountain roads and trails.
- Read the travel-safety pages before you plan your route, including any overland crossing.
- Save the emergency numbers; 112 works in all three countries.
Consular protection: who to call in the Caucasus
- 112 reaches the emergency services in Georgia, Armenia and Azerbaijan; in Armenia, 911 works too.
- In Armenia, 102 is the police, 103 an ambulance and 101 the fire service; in Azerbaijan, 102 is the police and 103 an ambulance.
- Embassies are in Tbilisi, Yerevan and Baku. The Telcomia app shows which mission is responsible for you, with address and phone.
- If you are an EU citizen and your country has no embassy or consulate in Georgia, Armenia or Azerbaijan, the embassy of any other EU country must help you on the same terms as its own nationals (Article 23 of the Treaty on the Functioning of the EU).
- The app keeps key emergency phrases ready to show on screen.

Questions travellers ask about Georgia, Armenia and Azerbaijan
Is there one eSIM for Georgia, Armenia and Azerbaijan?
Yes: a World plan covers all three. No smaller zone does, because Armenia is in the Middle East zone while Georgia and Azerbaijan are in Europe Extended.
Does EU roaming work in Georgia?
No. Georgia, like Armenia and Azerbaijan, is outside Roam Like at Home, so an EU SIM pays its operator's roaming rates there.
Should I buy three country plans instead?
Usually not. A country plan fits when most of your days are in one country, with a second plan for a short visit next door; for a trip shared between all three, one World plan is simpler than three plans to buy and set up.
Is there signal in the mountains?
Along the main routes, mostly. On high trails and in deep valleys, such as around Ushguli or on the way to Tatev, it can drop, so download offline maps first.
The short version
Georgia, Armenia and Azerbaijan are all outside EU roaming, and only a World plan covers the three on one eSIM. If most of your days are in one country, a country plan may fit better; either way, carry offline maps and check the travel-safety pages before crossing overland.

When should I activate my Georgia eSIM?
Each plan shows before you pay when it starts counting. Plans that start on connection start counting the first time they connect to a network in one of the countries they cover: install the eSIM before you leave, keep the line off until you arrive in Georgia, and you'll have data as soon as you land. Some also work in other countries (each plan lists which): if the line connects earlier, at home or on a layover, it starts counting there. Plans that start when you buy them are best bought on the day you'll start using them.
