Do I need to register my SIM with my passport?

Yes. Since 2025 every new prepaid SIM in Lithuania must be registered with your name and ID document. You can do it in store with your passport or residence permit, or online with some operators.

Can I use my Lithuanian SIM across the EU?

Yes. Under EU roam-like-at-home rules, EU operators include EU roaming, so your data and calls work in other EU countries up to a fair-use limit. Check your plan's roaming allowance.

Prepaid or a monthly contract?

Prepaid is easier when you arrive — no Lithuanian bank account or long-term commitment needed. A postpaid contract can be cheaper per month but usually wants a local payment method and an address.

Which operator has the best coverage?

All three (Telia, Bitė, Tele2) cover cities and most of the country well. Differences are small; pick on price and the bundle that fits how much data you use.

Local prepaid eSIM support is limited and changes often — ask in store. Travel eSIMs (Airalo and similar) work for arrival but are pricier and still need ID registration to comply with the law.

Best SIM card for students in Lithuania

The cheapest, simplest option for most students is a prepaid SIM from one of Lithuania's three operators — but since 2025 you must register it with your passport or residence permit at the point of sale.

The three operators (and their prepaid brands)

Lithuania has three mobile networks. Each sells a budget prepaid brand alongside its main one:

Network	Prepaid brand	Known for
Telia	Ežys / Extra	Wide coverage, customer service
Bitė	Labas	Fast data, simple bundles
Tele2	Pildyk	Lowest entry prices

Coverage differences are small in cities and on transport routes, so choose on price and the bundle that matches your data use, not the logo.

What it costs

A starter SIM is cheap — typically around 1 EUR. The real cost is the monthly bundle. Prices change often and operators run promotions, so confirm current figures on the operator's site before you buy.

Light user (mostly Wi-Fi, some maps and messaging): a small data bundle is usually enough.
Heavy user (streaming, hotspot, video calls): look at an "unlimited" or large-data monthly plan.

Compare before you commit

Open the Ežys, Labas and Pildyk plan pages side by side on your phone. The bundle that includes the most EU roaming data is the one worth a euro or two more if you travel.

The registration step you cannot skip

Since 2025, Lithuania no longer allows anonymous prepaid SIMs. You must give your name, ID document type and number, and an address before the SIM works (as of 2026 — see LRT).

In practice you have two routes:

In a store — bring your passport or residence permit (TRP). Staff register the SIM for you on the spot. This is the easiest route for new arrivals.
Online — some operators let you self-register using a photo of your ID plus a selfie, or via Smart-ID / bank login if you already have a Lithuanian account.

Local Lithuanians often register with Smart-ID or internet banking, which you likely won't have on day one — so the in-store route with your passport is the reliable one when you first arrive.

Where to buy

Operator stores in shopping centres (staff can register the SIM and help in English).
Supermarkets and kiosks (Maxima, Rimi, Iki) and petrol stations sell SIMs and top-up vouchers.
Vilnius and Kaunas airports — convenient on arrival, but usually more expensive.

EU, non-EU and Erasmus: does it differ?

The SIM itself works the same for everyone. The difference is the ID you show to register:

EU/EEA students: national ID card or passport is fine.
Non-EU degree students: passport on arrival; once you have your TRP, that works too.
Erasmus/exchange students: your passport (and visa/national ID) is enough for a short prepaid stay — no need for a long contract.

Topping up

Prepaid credit runs out, so top up via:

The operator's app (needs a card — a Wise or Revolut card works fine).
Top-up vouchers from supermarkets and kiosks (pay cash, enter the code).
The operator's website.

EU roaming included

Lithuanian operators follow EU "roam like at home" rules, so your data and calls work across the EU up to a fair-use cap. Handy for weekend trips — just don't rely on it as a permanent home connection in another country.

Quick recommendation

For a typical international student: buy a prepaid SIM in an operator store on your first week, register it with your passport, and pick a monthly data bundle. Switch to a postpaid contract later only if you find a clearly cheaper plan once you have a local bank account.
