Buy at the airport on arrival
Dialog and Mobitel both run 24-hour counters in the BIA arrivals hall. Unusually, the airport is a reasonable place to buy here rather than a rip-off.

Complete biometric registration
Mandatory under Sri Lankan telecom regulation. Your physical passport and a photo verification are required — a copy will not do.

Take a tourist pack to start
Dialog's tourist pack is around LKR 1,299 for roughly 9 GB plus local and international minutes over 30 days; Mobitel's is comparable. Cheap enough to use as a bridge while you settle.

Move to a local plan once you have an address
Postpaid needs a Sri Lankan address and usually a local bank account. Prepaid works indefinitely if you would rather not bother.

Things most newcomers don’t know
Biometric registration is mandatory, so bring the physical passport.
Sri Lankan regulation requires SIMs to be registered biometrically with photo verification. A photocopy or a photo on your phone will be refused. It is a two-minute process but it is not optional, and it means a SIM is not something a friend can pick up for you.

The airport counters are genuinely the right move here.
Unlike most countries, where airport SIMs are overpriced, Dialog and Mobitel run proper 24-hour counters at BIA at normal rates. Given you need PickMe working before you leave the terminal, buying on arrival is the sensible sequence.

Data is cheap enough to change how you use your phone.
Sri Lankan mobile data is among the cheapest in Asia. Tethering rather than arranging home broadband is a viable strategy for a short stay, which suits a nomad visa holder who may not want a fixed-line contract.

Coverage is good on the coasts and thinner in the hills.
Dialog generally has the broadest reach. If you plan to work from the hill country around Ella or Kandy rather than Colombo or the south coast, check coverage for that specific area before committing.

Common mistakes to avoid
- Arriving without your physical passport to hand for biometric registration.
- Assuming you can buy a SIM without registration — you cannot.
- Choosing a network on Colombo coverage when you plan to work from the hills.
- Signing a postpaid contract before you have an address and account.
Some of this may be out of date. Spotted something inaccurate? Help us keep it right for the next newcomer.
