Best eSIM for the Baltic States (Estonia, Latvia, Lithuania)

There's no dedicated Baltic bundle in co:sim's catalog, so a Tallinn-to-Riga-to-Vilnius loop comes down to a real choice: three single-country eSIMs, one per border you cross, or one broader Europe (42 areas) plan that happens to include all three Baltic states along with dozens of other countries. Neither is wrong; it depends on whether this trip stays inside the Baltics or continues elsewhere in Europe. This guide compares live plans for Estonia, Latvia and Lithuania, names the actual network each one runs on, and lays out when the regional alternative genuinely makes more sense than three separate purchases.

#What to Look For in a Baltic States eSIM

Four things matter for this specific trip: whether you're buying one eSIM per country or one regional plan for the whole loop, which local network each plan actually connects to (Estonia, Latvia and Lithuania each have their own carrier landscape), how long your validity window needs to run if you're spending a few days in each capital, and whether the plan reloads if the trip runs long. Border crossings between the three Baltic capitals happen by land, with no roaming toggle to think about within a single-country eSIM's own country, so the real planning decision is how many separate SIMs you're willing to manage against how much you'd pay for one broader plan instead.

#Estonia, Latvia and Lithuania eSIM Plans Compared

co:sim sells Estonia, Latvia and Lithuania as three separate single-country destinations, each with its own plan lineup:

All three run on 5G-capable networks, all support top-ups on most plan tiers, and every plan states a 90-day install deadline on its own page, so there's no guessing how long you have between buying and installing. For a loop that spends a handful of days in each capital, a 3-5GB, 7-30-day plan per country is a reasonable starting point; heavier data users or longer stays should size up per country rather than assume one plan covers the whole trip.

#Which Networks Power Each Baltic Country's Coverage?

Each Baltic country has its own distinct carrier landscape, and co:sim's plans connect to the networks that actually perform best in independent testing, not just whichever is cheapest to license.

In Estonia, co:sim's eSIM uses Tele2 and Telia. Opensignal's 2022 Estonia mobile network report found Telia won its Download Speed Experience award outright at 58.6 Mbps and Upload Speed Experience at 14.3 Mbps, both well ahead of competitors, while Telia and Elisa jointly led 4G coverage and availability (roughly 91-94%), at least 3.9 percentage points ahead of Tele2.

In Latvia, co:sim's eSIM uses Tele2 and LMT. The same Opensignal testing for Latvia found LMT won the 4G Coverage Experience award outright with a score of 8.4 out of 10, ahead of Tele2's 7.6, and LMT shared the Download Speed Experience award with Bite at 32 Mbps versus 29.3 Mbps, with Tele2 a distant third at 24.9 Mbps.

In Lithuania, co:sim's eSIM uses Telia and Tele2. According to nPerf data reported by Telecompaper, Telia was Lithuania's fastest mobile network in 2025 at 138.6 Mbps download and 86.3 Mbps upload, with Tele2 second at 83.7 Mbps download.

The pattern across all three: co:sim's plans connect through at least one network that independent testing ranks at or near the top in that specific country, rather than a single pan-Baltic network standing in for local performance.

#One eSIM or Three? Deciding Between Single-Country and Regional Plans

If this trip is only Estonia, Latvia and Lithuania, three single-country eSIMs are usually the simpler and often cheaper choice, since each plan is sized and priced for that country alone rather than for continent-wide coverage. If the same trip continues into other parts of Europe, co:sim's Europe (42 areas) eSIM is worth considering instead: it covers Estonia, Latvia and Lithuania along with 38 other European territories on one profile, from 500MB to 50GB. It is priced higher per plan than any single Baltic country plan, which makes sense given the much larger coverage footprint, so it's the better value only when the trip genuinely extends beyond the three Baltic capitals.

One regional option that does not currently apply here: co:sim's Europe (30+ areas) grouping is listed as a destination but currently has no active plans for sale, so it isn't a live purchasing option today regardless of which countries it's meant to cover. Check current plan availability before assuming a specific regional grouping is bookable.

#How to Set Up Your Baltic eSIMs Before You Land

Buy and install each eSIM (or the one regional eSIM) before you fly, on hotel or home Wi-Fi rather than waiting until arrival. co:sim emails the QR code within seconds of checkout; scan and let the profile download, then leave it inactive until you land in that specific country, since most plans start their validity clock on first connection rather than at purchase. If you're running three separate country eSIMs, install all three before departure and simply switch which one is active as you cross each border, rather than trying to install a new one from inside the country you've just entered.

Estonia has its own free eSIM trial for new customers, a practical way to confirm your phone installs and activates correctly on Tele2/Telia before committing to a paid plan for the rest of the loop.

Latvia and Lithuania each have their own equivalent free trials too, at co:sim's Latvia offer and Lithuania offer, useful if you'd rather test each country's specific network before the paid plan takes over.

#FAQ

#Is there a single eSIM that covers Estonia, Latvia and Lithuania together?

Not as a dedicated Baltic bundle. co:sim sells Estonia, Latvia and Lithuania as three separate single-country eSIMs, and there is no plan scoped specifically to just those three countries as a group. The closest live alternative is co:sim's Europe (42 areas) eSIM, which does include all three Baltic states, but also covers 38 other European territories on the same plan, so it's priced and sized for continent-wide travel rather than a Baltic-only loop, and buying it purely to cover a Tallinn-Riga-Vilnius trip means paying for coverage you won't use. For a trip that stays inside Estonia, Latvia and Lithuania, three single-country plans are usually the more cost-effective choice, each sized to what that specific leg of the trip actually needs; the regional plan earns its higher price only when the itinerary extends well beyond the Baltics into other parts of Europe.

#Which network does co:sim's Latvia eSIM use, and is it any good?

co:sim's Latvia eSIM connects through Tele2 and LMT, both named on the plan page itself rather than left unstated. Independent testing from Opensignal's 2022 Latvia mobile network report found LMT outright won the 4G Coverage Experience award with a score of 8.4 out of 10 versus Tele2's 7.6, and LMT shared the Download Speed Experience award with Bite at 32 Mbps, ahead of Tele2's 24.9 Mbps and comfortably ahead of the country average. In practical terms, that means co:sim's Latvia plan connects to the network Opensignal's testing found had the strongest coverage in the country at the time of that report, not a lower-tier or resold connection riding on someone else's infrastructure. Coverage and speed rankings do shift over time as carriers invest in new towers, so treat this as the most recent independently tested snapshot rather than a permanent guarantee.

#Do I need to buy separate eSIMs for each Baltic capital, or does one carry over?

Each co:sim country eSIM works only within that specific country's coverage area, so a Latvia eSIM won't connect once you cross into Estonia or Lithuania, the same way a physical local SIM bought in Riga wouldn't work once you reached Vilnius. If your trip covers all three, you'll either need three separate country eSIMs, installed before departure and switched between as you cross each border, or one broader Europe (42 areas) eSIM that covers all three on a single profile without any switching at all. There's no single-Baltic-country eSIM that quietly extends into the neighboring two once you land; the coverage area listed on each destination page is exactly what you get, no more. Deciding between the two approaches mostly comes down to how many countries the wider trip actually touches, not just these three.

#Is the Europe (42 areas) eSIM cheaper than buying Estonia, Latvia and Lithuania separately?

Usually not, if the trip stays inside the three Baltic countries. The Europe (42 areas) plan is priced for coverage across 41 territories, not three, so per-country it typically costs more than buying Estonia, Latvia and Lithuania as separate single-country plans sized to what you actually need in each leg of the trip. A short stay in each capital rarely needs the kind of data allowance the regional plan is built around, which is sized for travelers moving through many countries over a longer trip. The regional plan becomes the better value once the itinerary adds countries beyond the Baltics, since at that point it replaces what would otherwise be four or more separate purchases with one, and the convenience of not switching eSIMs at each border starts to outweigh the per-country cost difference.
