If you are flying from the UK to see family in Colombo or Galle, you do not want to land and hunt for a SIM card. You want data on your phone before you leave, and you want it to work the moment you switch off airplane mode. A Sri Lanka eSIM does exactly that.
If you are an India-origin traveller, you may also be keeping an Indian SIM active for bank OTPs. Your Sri Lanka eSIM handles data; your Indian SIM handles the OTPs. No swapping cards, no roaming bills.
The right amount depends on how long you stay and what you do.
| Trip length | What you do | Plan |
|---|---|---|
| 3-4 days | Maps, WhatsApp, occasional social media | 1GB |
| 5-7 days | Maps, WhatsApp video calls, some streaming | 3GB |
| 7-10 days | Streaming, video calls, remote work | 5GB |
| 2+ weeks | Heavy use, hotspot for laptop | 10GB+ |
Our Sri Lanka plans start from $3.49. You choose the size, pay once, and data starts when you connect to a local network at the destination.
Arrival at Bandaranaike International Airport: Free Wi-Fi exists but is slow and requires an OTP to your home number. If you have not installed your eSIM before landing, you will be stuck with that slow Wi-Fi or a roaming data charge. Install at home on Wi-Fi. It takes two minutes.
Hotspot and local apps: You can hotspot from your Sri Lanka eSIM, useful for a laptop. Some local services (like railway booking sites) may prefer a Sri Lankan IP or payment method, but your eSIM works for general browsing and apps like Uber or PickMe without issues.
Your eSIM arrives as a QR code by email within a minute of purchase. Install it on Wi-Fi before you travel. Data starts on first connection at the destination. No contracts, no hidden fees.
Follow our installation guide for iPhone and Android if you need step-by-step help.
If you hold an Indian SIM, keep it active for bank alerts and OTPs. You can recharge your Indian number from abroad, Airtel, Jio, Vi and BSNL are all covered. Your Sri Lanka eSIM handles data; your Indian SIM handles the messages.
If you are a UK resident, your home SIM can stay in the phone on roaming for calls, just switch data to the eSIM.
Ready to travel? Get your Sri Lanka eSIM and land connected.
Yes. If your phone is unlocked and supports eSIM (iPhone XS or newer, most recent Android flagships), you can install a Sri Lanka eSIM before you travel. Data starts when you connect to a local network on arrival.
For a 7-day trip, 5GB is usually enough if you use maps, WhatsApp and occasional social media. If you plan to stream video or work remotely, go for 10GB. For a longer stay of two weeks or more, consider 20GB.
Usually yes, or at least comparable. A local SIM at Bandaranaike International Airport costs around $15-$20 for similar data. Our Sri Lanka plans start from $3.49 and you avoid the queue at the airport kiosk.
Your home SIM will work on roaming, but you will pay roaming rates. Keep it enabled for OTPs and bank alerts, but switch data to the eSIM to avoid high data roaming charges.
Yes. You can use your Sri Lanka eSIM as a hotspot for a laptop or tablet. Check your phone's hotspot settings once you have connected to the local network.
You can buy a new eSIM or top up if available. For longer trips, consider buying a larger plan upfront, it works out cheaper than buying multiple smaller ones.
For most trips a 5GB to 10GB data eSIM valid for 30 days is the right size: Slashtel's 5GB plan for Sri Lanka is $7.99 on Hutch, Etisalat and Dialog. Install it before you fly, keep your home SIM on for calls and bank texts, and top up the same eSIM if you run low.
If your phone supports eSIM, an eSIM is simpler than a local SIM card: nothing to collect at the airport, no passport registration, and your home SIM stays in the phone for calls and OTP texts. A physical SIM only makes sense for long stays where you need a local phone number.
From $3.49 for 1GB valid 7 days, as of 9 October 2026. Longer trips: two weeks from $6.99 (3GB), one month from $6.99 (3GB).
$1.60 per GB on the 5GB plan (30 days, $7.99). Bigger plans usually cost less per GB, so buy the size you expect to use.
Hutch, Etisalat, Dialog, Mobitel and 3, with speeds up to 5G where available. The eSIM picks the strongest network automatically.
No. Slashtel eSIMs are data only, with no local number, calls or SMS. WhatsApp and other internet calls work, and your home SIM can stay on for calls and OTP texts.
Validity starts when the eSIM first connects to a network in Sri Lanka, not when you buy it, so you can buy and install it before you travel.
After payment Slashtel emails a QR code within a minute. Scan it in your phone settings while on Wi-Fi at home, then switch on data roaming for the eSIM when you land.
Your phone must support eSIM and be carrier-unlocked. Dial *#06#: if an EID appears, the phone supports eSIM.
Yes. Hotspot and tethering are allowed on Slashtel eSIMs.
Pick a plan, pay by card. QR arrives by email within a minute.
Scan the QR on Wi-Fi at home. Takes two minutes. Keep your main SIM in.
