📲 Can I keep my phone number when I switch provider in Lithuania?

The short answer

You can keep your phone number when changing provider. Apply to the new one: the number must work there within one working day of the date in your request, or of the request if you gave none. The old provider may not charge for porting.

You can usually take your mobile or landline number with you to a new provider. You ask the new provider to transfer it, and the number moves on an agreed day.

📜 The rules in Lithuania

Compensation

A provider that delays or obstructs porting owes you compensation: per day of delay, one base amount (average monthly revenue per voice-service user in RRT's latest annual report); if the number is never moved, a month of days; other breaches, 1–10 base amounts.

The details

  • Your contract with the old provider ends on the day the number moves. If you port before your minimum term ends, the old provider can still claim the early-termination charges agreed in the contract, so choose the porting date carefully. (rrt.lt)
  • You keep the right to port your number for 3 months after your contract ends, unless you clearly gave it up. Numbers cannot be moved between fixed and mobile networks. (e-seimas.lrs.lt)
  • If porting fails, the old provider must keep serving you on the same terms until it succeeds. After porting, prepaid users can ask for unused credit back; a fee applies only if the contract says so and matches real costs. (e-seimas.lrs.lt)
  • With a device that has a built-in SIM (eSIM), you can switch mobile provider and keep your number without changing the SIM module and without handing over the device. (e-seimas.lrs.lt)

🪜 Step by step

  1. Do not cancel the old contract firstIf you end the old contract before the transfer, the number can be lost. Let the new provider request the transfer.
  2. Get your details readyYou usually need the number, the name on the old contract and sometimes a customer number or transfer code from the old provider.
  3. Agree the transfer dateThe new provider tells you when the number moves. Keep the old SIM or line in use until then.
  4. Check that everything worksTest calls and messages on the new SIM or line, and check that the old provider sends a final bill and stops charging.

❓ Questions

How long does a number transfer take?

It is usually quick. If the rules in Lithuania set a maximum time or compensation for delays, you find them on this page.

Can I keep my number if I still owe the old provider money?

You still have to pay what you owe under the old contract. Ask the new provider before you switch whether anything could hold up the transfer.

Can I move a mobile number to a landline, or the other way round?

Usually not: mobile numbers move between mobile providers, landline numbers between landline providers.
