No Premium tier is selectable on this Sri Lanka product. Check exact data, speeds, duration, hotspot terms and live price on the Sri Lanka product page. Fixed data is a total allowance; the Unlimited tiers have their own daily full-speed terms.

Airport arrival and first-night plans

Save the airport named on your ticket, your Colombo accommodation address and pickup instructions before leaving Wi-Fi. The main international airport serving Colombo is outside the city, so plan the onward transfer separately. Confirm pickup points, fares and current schedules with your transport provider. After following your plan's activation guidance, supported data can help you contact your accommodation; an eSIM does not include transport or guarantee signal everywhere in the airport.

Colombo and onward island travel

Use supported data for directions around your accommodation, meetings and planned city visits. If you continue by road or rail, save tickets, route details and offline maps ahead of time and choose validity for the full journey. Coverage and speeds vary by local network, terrain, buildings and congestion; remote roads and hill-country stretches may have limited service. A larger allowance cannot create signal where no supported network is available.

Install and troubleshoot

1. Choose a Sri Lanka plan and duration, complete checkout and open the emailed QR code on another screen.
2. Connect an unlocked, eSIM-compatible phone to stable Wi-Fi. On iPhone, open Settings > Cellular/Mobile Data > Add eSIM > Use QR Code. On Android, find Add eSIM in SIM manager or Network & internet; labels vary.
3. Scan the code, label the new line AloOui and follow your delivery instructions. Do not delete the installed eSIM.
4. On arrival, choose AloOui for mobile data and follow the selected plan's activation guidance. If data fails, check validity, mobile data and instructed roaming on that line, toggle airplane mode, verify any APN instructions in your email and try automatic network selection. Visit the AloOui Help Center for support.
