Why use an eSIM in Sri Lanka
Sri Lanka is compact but packed with things to navigate: tuk-tuk rides to book, train tickets to check, beaches and tea estates to map. An eSIM keeps you connected the whole way.
Instant delivery to your inbox, install before you fly
No roaming fees that blow up your bill
Keep your home number active for calls and texts
Your physical SIM stays untouched for WhatsApp and banking
Sri Lanka has solid mobile infrastructure run by a few strong operators:
Dialog — the largest network, with wide 4G and growing 5G
Mobitel (SLT-Mobitel) — excellent reach, strong in rural areas
Hutch — competitive 4G, good value in cities
Expect reliable 4G in Colombo, Kandy, and Galle, with 5G expanding across the capital. Coverage along the south coast and hill country is good; very remote jungle or high-altitude trails may dip to slower speeds.
How to get connected
1. Buy your Sri Lanka eSIM online and check your email for the QR code.
2. Scan the QR under your phone's mobile-data or eSIM settings.
3. Enable the line and turn on data roaming for the eSIM — you'll be online the moment you land.

Light (maps, chat, email): 1–3 GB for a short trip
Medium (social, daily browsing, some streaming): 5–10 GB

Will my phone work with an eSIM?
Most phones from the last few years support eSIM — iPhone XS and newer, Google Pixel 3 and newer, and recent Samsung Galaxy models. Check your settings for an "Add eSIM" option.
When should I install it?
Install at home over Wi-Fi before you travel, then simply enable the line when you land. You can set it up days ahead without using any data.
Can I keep my WhatsApp number?
Yes. WhatsApp is tied to your existing number, not the eSIM. Keep your home SIM active and WhatsApp works exactly as before while you use the eSIM for data.
Frequently asked questions
Does a HelloSIM eSIM work in Sri Lanka?
Yes. HelloSIM offers data eSIM plans for Sri Lanka that connect to major local networks, giving you coverage in Colombo, Kandy, and popular travel spots as soon as you install and activate the eSIM.
Is my phone compatible with an eSIM for Sri Lanka?
Most iPhones from the XS onward, Google Pixel 3 and newer, and recent Samsung Galaxy flagships support eSIM. Your phone must also be carrier-unlocked. Look for an 'Add eSIM' option in your settings to confirm.
How do I check if my phone supports eSIM before travelling?
On iPhone, dial *#06# and look for an EID, or check Settings > General > About. On Android, look for 'Add eSIM' or 'Download a SIM' under your SIM settings. If it's there, your phone supports eSIM.
Which networks does HelloSIM use in Sri Lanka?
HelloSIM connects to Sri Lanka's major mobile operators, which include Dialog, Mobitel, Hutch, and Airtel. Your eSIM automatically registers on a partner network with good local coverage, so you don't need to pick one manually.
How do I buy and install a HelloSIM eSIM for Sri Lanka?
Choose a Sri Lanka plan on the HelloSIM site, complete payment, and receive a QR code by email. Scan it in your phone's eSIM settings while on Wi-Fi, and the profile installs in about a minute.
How do I install the eSIM QR code on an iPhone?
Go to Settings > Mobile Data (or Cellular) > Add eSIM > Use QR Code, then scan the code from your HelloSIM email and follow the prompts to complete setup.
How do I install the eSIM on an Android phone?
Open Settings > Network & internet > SIMs > Add eSIM (or Download a SIM instead) and scan the HelloSIM QR code. Menu names vary slightly by phone brand, but the steps are the same.
Can I install the Sri Lanka eSIM before I leave home?
Yes, and it's recommended. Install the eSIM while you have reliable Wi-Fi at home, since scanning the QR code needs internet. You can wait to activate it until you arrive in Sri Lanka.
When should I activate my Sri Lanka eSIM?
Install ahead of time, but activate when you arrive or on your trip start date, because the validity period usually begins on first use or first network connection. Confirm your plan's activation rule at checkout.
Will I have internet when I land at Colombo airport?
Yes, if your eSIM is installed and set to activate on arrival. Once you land at Bandaranaike International Airport near Colombo and connect to a local network, data should start working before you leave the terminal.
How much data do I need for a week in Sri Lanka?
For a week of maps, messaging, social media, and light streaming, most travelers are comfortable with around 3 to 8 GB. Heavy streamers or hotspot users should choose more, while light users can pick a smaller plan.
How much data do I need for two weeks in Sri Lanka?
A typical two-week trip with daily navigation and browsing runs roughly 8 to 15 GB. If you stream video often or tether other devices, size up or consider a larger plan.
Does HelloSIM offer large or unlimited data plans for Sri Lanka?
HelloSIM offers several plan sizes for Sri Lanka, and where a high-data or unlimited tier is available it will be listed on the Sri Lanka plan page. Check the current options at checkout for the largest allowance.
How much does an eSIM for Sri Lanka cost?
Cost depends on the data amount and validity you choose, so a small short plan is cheaper than a large multi-week one. Exact prices are shown per plan on the HelloSIM Sri Lanka page at checkout.
Is there 4G coverage across Sri Lanka?
Yes. 4G LTE is widely available in Sri Lanka's cities, towns, and along main roads, which is plenty for maps, messaging, and streaming. Coverage can thin out in remote hills, jungle, or rural interior areas.
Is there 5G in Sri Lanka?
5G is still limited in Sri Lanka and mainly found in select urban areas, so most of your connection will be on 4G LTE. That's more than adequate for navigation, social media, and video calls during your trip.
How fast is mobile data in Sri Lanka?
On 4G, speeds in cities like Colombo are good for streaming, browsing, and video calls. Speeds can drop in remote areas, hill country, and some coastal or safari regions where towers are sparser.
Is coverage good in tourist areas like Kandy, Galle, and Ella?
Yes, popular destinations such as Kandy, Galle, Ella, and the southern beaches generally have solid 4G coverage. Signal may weaken in the deep interior, on some train routes through the hills, and inside national parks.
Will the eSIM work on the scenic Kandy to Ella train?
You'll have signal for much of the popular Kandy-to-Ella hill-country train ride, but expect drops in tunnels and remote mountain stretches. Download offline maps and any tickets in advance so you're covered when signal fades.
Can I use my HelloSIM eSIM for hotspot or tethering in Sri Lanka?
Yes, HelloSIM data eSIMs support personal hotspot and tethering, so you can share your connection with a laptop or tablet. Remember that tethering uses your data allowance faster.
Can I keep my home phone number while using the eSIM in Sri Lanka?
Yes. The eSIM acts as a second line alongside your existing SIM, so your home number stays active for calls and texts on your main line. Keep data roaming off on your home SIM to avoid charges.
How does dual SIM work with the Sri Lanka eSIM?
Your phone runs your physical SIM and the HelloSIM eSIM at the same time. Set the HelloSIM eSIM as your data line in Sri Lanka, and keep your home SIM active for calls and texts if you want to stay reachable.
Do I need to change APN settings for the eSIM to work in Sri Lanka?
Usually not, since the APN configures automatically. If data doesn't work after activation, HelloSIM provides the correct APN to enter manually in your eSIM's mobile data settings.
My Sri Lanka eSIM isn't connecting, what should I do?
Check that data roaming is ON for the HelloSIM line, the eSIM is selected as your data line, and the plan is active. Toggle Airplane mode on and off, restart the phone, or manually select a network like Dialog or Mobitel.
Why do I need to turn on data roaming for a Sri Lanka eSIM?
The eSIM connects to Sri Lankan networks as a visiting profile, so data roaming must be enabled on the HelloSIM line for it to work. This won't cause extra charges because your plan already covers the data.
Does the HelloSIM eSIM include calls and SMS in Sri Lanka?
HelloSIM plans are data-only and don't include a Sri Lankan phone number for standard calls or texts. You can still call and message over the internet using WhatsApp, FaceTime, or similar apps.
How do I make calls in Sri Lanka with a data-only eSIM?
Use internet-based apps like WhatsApp, FaceTime, Viber, or Telegram over your eSIM data. WhatsApp is widely used in Sri Lanka, so most hotels, guides, and drivers can be reached that way.
Can I top up or add more data if I run out in Sri Lanka?
Yes. If you run low, you can buy a new plan or a top-up through your HelloSIM account, and the added data applies to your existing eSIM without reinstalling anything.
What happens when my data or validity runs out?
When your data allowance or validity period ends, the eSIM stops carrying data. You can purchase a fresh plan or top-up to continue, and the same installed profile can often be reused.
Can I use the same Sri Lanka eSIM in India or the Maldives?
A Sri Lanka-only plan covers Sri Lanka. If your trip includes India, the Maldives, or other stops, choose a regional plan that lists those countries or buy a separate plan for each.
Does HelloSIM offer a regional Asia plan that includes Sri Lanka?
Yes. If you're visiting several countries in the region, HelloSIM offers regional plans covering multiple destinations on one eSIM. Check the regional plan's coverage list to confirm Sri Lanka and your other stops are included.
What is the emergency number in Sri Lanka?
Dial 119 for police and 1990 for the Suwa Seriya ambulance service in Sri Lanka. There is also a general emergency line, 112, and tourist police assistance in main visitor areas.
Can I call emergency services on a data-only eSIM?
Emergency numbers can be dialed from any phone with a mobile signal, even on a data-only eSIM. If your home SIM is also in the phone, use whichever line has coverage at the time.
Do I still need Wi-Fi if I have the eSIM?
Not to stay connected, since your eSIM provides data anywhere with coverage. Wi-Fi in Sri Lankan hotels and guesthouses can be inconsistent, so having your own eSIM data is often more reliable for maps and messaging.
Should I download offline maps before my trip to Sri Lanka?
Yes, strongly recommended. Coverage can drop in the hill country, national parks, and rural roads, so downloading Google Maps offline for your route ensures you can still navigate when signal is weak.
Is the eSIM reliable for ride-hailing apps like PickMe or Uber?
Yes. Your eSIM data lets you use PickMe and Uber, which are popular for getting around Colombo and other cities. A steady data connection also helps with booking tuk-tuks and confirming pickups.
Can I get a refund if my Sri Lanka eSIM doesn't work?
If you hit an installation or activation issue, contact HelloSIM support before using the plan and they can help troubleshoot or advise on your options. Refund eligibility depends on whether the eSIM was activated and used.
How long is a Sri Lanka eSIM plan valid?
Validity depends on the plan, commonly ranging from a few days up to around 30 days. The exact validity window is shown on each plan at checkout and typically starts counting from activation.
Can I install the eSIM on more than one device?
No. Each eSIM QR code is tied to a single device and can only be installed once. To connect another device, buy a separate plan or share data using your phone's hotspot.
Do I need a local ID or SIM registration to use a HelloSIM eSIM?
No. Unlike buying a local Sri Lankan SIM, which requires passport registration, a HelloSIM travel eSIM needs no local ID or paperwork. You buy online, install the QR code, and connect on arrival.
Is an eSIM better than buying a tourist SIM at Colombo airport?
An eSIM installs before you fly and connects instantly on arrival, with no queue at an airport counter or passport registration. It's a convenient alternative to hunting for a tourist SIM kiosk after a long flight.
What should I do with the eSIM after my trip to Sri Lanka?
Once the plan ends, you can simply delete the eSIM profile in your phone's settings. Your physical SIM and home number are unaffected, and you can add a new HelloSIM eSIM for your next trip.
