Bottom line: two things changed for Sri Lanka in the last twelve months, and neither is reflected in most guides. From 25 May 2026 the Department of Immigration and Emigration issues the tourist ETA free of charge to nationals of 40 countries — 30 days, double entry — but the ETA itself is still mandatory for everyone, so “visa-free” is the wrong word. And a local prepaid SIM is not a walk-up purchase: under the Subscriber SIM Card regulations gazetted as No. 2134/56 on 2 August 2019, a passport can stand in for the national identity card only if you also supply billing information proving your address, and the operator must disconnect the line if the scanned documents are not uploaded within one month of activation. A travel eSIM issued abroad falls outside those regulations entirely. On the network side, Sri Lanka only entered the public 5G era in December 2025, when Dialog and SLT-Mobitel launched commercially after the TRCSL spectrum auction.

This page was written in August 2026 from primary sources: the Sri Lankan immigration department’s own notice, the text of the SIM regulations as published in the Government Gazette, the telecom regulator’s licensing pages, and newswire reporting of the 5G launch. Every figure is dated, because the entry rules changed three months ago and the network changed eight months ago.

The entry rule: free ETA is not visa-free

On 7 May 2026 the Sri Lankan Parliament approved regulations under the Immigration and Emigration Act waiving the tourist ETA fee. The Department of Immigration and Emigration’s special notice to short-term visitors sets out what actually applies from 25 May 2026:

• 40 nationalities get the tourist ETA free of charge — including Australia, Canada, China, France, Germany, India, Indonesia, Israel, Italy, Japan, Malaysia, the Netherlands, New Zealand, Poland, Russia, Saudi Arabia, South Korea, Spain, Sweden, Switzerland, Thailand, Türkiye, the UAE, the United Kingdom and the United States.
• The ETA is still compulsory. The notice is explicit: all foreign nationals, including those 40 and the bilateral-agreement countries (Maldives, Seychelles, Singapore), must obtain the Electronic Travel Authorization before arrival. The fee is waived; the application is not.
• 30 days, double entry, counted from first arrival — useful if you are pairing Sri Lanka with a side trip to the Maldives or India. Maldivian nationals get 90 days.
• Diplomatic, official, service and ordinary passports all qualify under the scheme.
• Staying longer costs money. Extensions beyond 30 days require payment of the applicable visa fee, and ETA fees paid before 25 May 2026 are non-refundable.

Apply through the official ETA portal operated by the Department of Immigration and Emigration. Because the fee is now zero for these nationalities, any site charging you a “processing fee” is a reseller, not the government.

What the SIM regulations actually say

Most travel advice reduces this to “bring your passport.” The Telecommunications Regulatory Commission of Sri Lanka publishes the actual instrument: the Subscriber SIM Cards regulations No. 01 of 2019, made by the President under the Sri Lanka Telecommunications Act No. 25 of 1991 and published in Gazette Extraordinary No. 2134/56 of 2 August 2019. Schedule I governs retail subscribers — which is you — and four provisions matter to a visitor:

1. A signed application form is mandatory, with the identity number, permanent address and new telephone number recorded.
2. A photocopy of the national identity card, driving licence or valid passport, signed by the subscriber, must accompany it — so a passport is expressly sufficient as the identity document.
3. But if a passport is accepted in place of the NIC, the subscriber “shall be required to submit billing information in proof of such person’s address.” This is the provision nobody mentions. In practice it is satisfied with a hotel or guesthouse booking confirmation — which is why the airport counter asks where you are staying, and why it is worth having that confirmation on your phone before you land.
4. The operator must upload scanned copies within one month of activation, and must disconnect the line if that is not done. If a shop registers your SIM casually and never completes the paperwork, the number stops working — and you will be somewhere between Ella and Arugam Bay when it happens.

Why a travel eSIM sits outside all of this

The regulations apply, by their own terms, to “every operator licensed under Section 17(2) of the Act to provide digital cellular mobile services” — that is, to Sri Lankan licensees and the SIMs they issue. An eSIM profile downloaded from an international travel-data provider before departure is issued outside Sri Lanka. Your handset attaches to Dialog, SLT-Mobitel, Airtel or Hutch as an inbound roamer under the home operator’s identity. There is no Sri Lankan subscriber record, no address-proof requirement, and no one-month upload deadline hanging over your connection.

One further point that catches people out: TRCSL also regulates approval for bringing mobile devices into the country, capping personal imports at five units and requiring written approval above that. A single phone for personal use is not a problem; arriving with a bag of handsets is a customs matter, not a formality.

The network: 5G is eight months old here

Sri Lanka ran 5G pilots for years, but the public phase began only in December 2025. TRCSL closed its spectrum auction that week; Dialog Axiata and SLT-Mobitel were the only bidders, both taking blocks in the 3.5 GHz band, with Dialog additionally securing 27 GHz. Xinhua reported the commercial launches on 20 December 2025: SLT-Mobitel at One Galle Face Mall in Colombo, and Dialog’s “5G Ultra” running on over 220 live 5G sites.

Read that number carefully, because it sets expectations correctly. Two hundred and twenty sites is a launch footprint, not national coverage. What it means for a 2026 trip:

• Colombo, Kandy and the main corridors: expect to see 5G, and expect it to be genuinely fast where you do.
• The hill country, the east coast and the national parks: plan on LTE. The Ella–Badulla railway, Yala, Wilpattu and much of the Arugam Bay road are LTE-or-less territory, and some of it is no-signal territory.
• Four networks share the country — Dialog, SLT-Mobitel, Airtel and Hutch — with Dialog and SLT-Mobitel holding the broadest coverage. Independent measurement over the year to mid-2026 has put Airtel ahead on raw mobile download speed and SLT-Mobitel ahead on fixed broadband, which is a reminder that “fastest” and “best covered” are different questions.
• Download offline maps before you leave Colombo. This is the single piece of advice that most reliably saves a Sri Lankan road trip.

Devices, bands and setup

• LTE runs mainly on bands 3 (1800), 8 (900), 1 (2100) and 40 (2300), with 5G on n78 (3.5 GHz). Phones sold in Europe, India, Japan and Australia cover these comfortably; some North American models omit band 40, which costs you capacity in Colombo but not connectivity.
• The handset must be carrier-unlocked and eSIM-capable. The standard your phone implements is the GSMA’s consumer remote SIM provisioning specification, which also publishes the supported-device list.
• Install the profile before you fly. Downloading an eSIM needs an internet connection. Bandaranaike International has Wi-Fi, but you will be walking straight into a queue for immigration and then a pre-arranged transfer, and that is a poor moment to be troubleshooting.
• Keep the home profile for SMS. Bank one-time passwords still arrive there, and you will want them if you are booking trains or transfers online.

A checklist for a 2026 trip

1. Check whether your nationality is on the 40-country free-ETA list, then apply on the official portal anyway — the ETA is required either way.
2. Save the ETA approval offline, along with your accommodation confirmation. You may need the second one at a SIM counter, not just at immigration.
3. Decide: Sri Lankan number, or just data? If data, install the eSIM at home and skip Schedule I entirely.
4. If you do buy locally, watch the registration actually happen and keep the receipt — the one-month disconnection rule is the operator’s obligation, but you are the one who loses service.
5. Turn off data roaming on the home profile before you fly.
6. Download offline maps for the hill country and any national park on your itinerary.
7. If you are combining Sri Lanka with other stops, the rules differ sharply. We keep pages for India, Thailand and Singapore, and the eSIM basics guide covers the setup steps common to every destination.

FAQ

Is Sri Lanka visa-free in 2026?

No — the fee is waived, not the requirement. From 25 May 2026, nationals of 40 countries receive the tourist ETA free of charge for 30 days with double entry, but the immigration department states that all foreign nationals must still obtain an ETA before arrival.

Do I need to register a travel eSIM in Sri Lanka?

No, if it was issued outside the country. The 2019 SIM regulations bind operators licensed in Sri Lanka and the SIMs they issue. A foreign travel eSIM attaches as inbound roaming under its home operator’s identity, so there is no Sri Lankan subscriber record to create.

What do I need to buy a local prepaid SIM as a visitor?

Your passport, a signed application form, and — because a passport is being accepted in place of the national identity card — billing information proving your address, which in practice means your accommodation booking. Have the confirmation accessible on your phone or printed.

Can my local SIM be cut off after I have already paid for it?

Yes. Schedule I requires the operator to upload scanned registration documents within one month of activation and to disconnect the connection if that is not done. It is the operator’s obligation, but the consequence lands on you, so buy from an official outlet rather than a street vendor.

Does Sri Lanka have 5G?

Since December 2025, yes, commercially. Dialog and SLT-Mobitel launched after the TRCSL spectrum auction, both on 3.5 GHz. Dialog’s launch network ran on over 220 live sites — a metropolitan footprint. Outside Colombo and the main corridors, plan on LTE.

Which operator should my eSIM use?

Dialog and SLT-Mobitel have the broadest coverage and are the two carrying 5G, which matters most if your itinerary leaves the Colombo–Kandy–Galle triangle. Many travel eSIMs attach to whichever network is strongest at your location, which is usually the better outcome.

Can I bring spare phones into Sri Lanka?

Up to five devices for personal use, per TRCSL’s device-approval rules. Beyond that you need written approval, supporting documents and, potentially, payment of charges. One phone and a tablet is unremarkable; a case of handsets is not.

Can I keep my home number while using a Sri Lankan eSIM?

Yes, on any dual-SIM handset. Keep the home profile active for SMS and calls with data roaming switched off, and set the eSIM as the data line. This keeps bank one-time passwords arriving without roaming charges.
