The shape of a Sri Lanka trip
You came for two weeks: Colombo, the train through the hill country to Kandy and Ella, a few days at Mirissa or Unawatuna, the leopards at Yala. You're now in week five. The hill country added two days, the east coast at Arugam Bay added a week, and you're still trying to fit in Jaffna in the north. Sri Lanka stretches; the island is small but the loop you'll actually take through it isn't.
Roamzy charges $4.71 per gigabyte in Sri Lanka, which is $0.0046 per megabyte. Real-time billing on actual usage. No expiry on the balance. No reset. No subscription you forgot to cancel. One per-MB rate across 192 countries — the same on day three as on day forty.
How much does Roamzy cost over a long stay?
Take 1 GB/day as the realistic average. Hostels and guesthouses have Wi-Fi mostly; the trains and buses are where cellular earns its keep. The famous Kandy–Ella train is essentially a five-hour data run for everyone holding a phone out the door:
| Trip length | Roamzy ($4.71/GB) | Local tourist SIM (re-bought) | Roaming on home number |
|---|---|---|---|
| 2 weeks (14 GB) | $65.94 | $15–35 (7-day pack + top-up) | $80–180 ($5–13/day) |
| 1 month (30 GB) | $141.30 | $30–65 (two packs back-to-back) | $200–450 |
| 2 months (60 GB) | $282.62 | $60–120 (three to four packs) | not realistic — nobody does this |
Competitor prices in columns 3 and 4 are 2025 ranges based on typical offerings; exact figures depend on your home carrier and the airport store you visit. Roamzy's rate in column 2 is our actual published rate from the pricing page.
A local Sri Lankan SIM at Bandaranaike (CMB) is cheap. The trade is paperwork at the kiosk, a tariff window that resets every 7 or 30 days, and the math when you're up at six weeks: multiple SIMs, multiple registrations, multiple resets. Roamzy keeps one rate, one balance.
What matters on a long trail?
- The Kandy–Ella train. The classic hill-country ride is six to seven hours of data: photos out the door, video to family, the camera-translator on Sinhala-only station signs. Power outlets are inconsistent — bring a battery.
- Guesthouse Wi-Fi outside Colombo is uneven. Cafés handle a video call; smaller guesthouses up-country fall to barely-loading after dark. Cellular becomes primary.
- Ride-hail is PickMe and Uber. Colombo is well-covered; Kandy and Galle are mixed; smaller towns are tuk-tuks negotiated at the curb.
- Translator earns its keep. Sinhala and Tamil signage outside the tourist corridor is normal. Camera mode on a hand-painted bus board works only with data.
- Card payments work in chains and city restaurants; small markets and rural guesthouses want LKR cash. ATMs dispense LKR; foreign cards work on most networks.
Monthly data budget shapes up like this: maps ~5 GB, translator ~2 GB, messaging and home calls ~8 GB, ride-hail ~1 GB, bookings and photo upload to Telegram ~10 GB, the rest is OS background. That's the 30 GB month.
Where does Roamzy work in this country?
- Colombo, Negombo, Galle, Kandy, Jaffna — solid LTE in the cores, 5G rolling out in the capital
- The southern coast (Mirissa, Unawatuna, Tangalle, Hikkaduwa) — strong LTE end to end
- Hill country (Ella, Nuwara Eliya, Haputale) — LTE in the towns, weakening on the tea-estate back roads
- The Kandy–Ella train — near-continuous LTE through the valleys; brief drops in tunnels
- Yala, Wilpattu, Udawalawe national parks — patchy 4G; the deeper into the park, the less signal
- The northern peninsula (Jaffna, Mannar) — LTE in towns, lighter on the long causeway roads
- The east coast (Trincomalee, Arugam Bay) — solid in resort zones, thinner between

What are Roamzy's honest limitations?
Long-trip travelers historically lose money to three things, and Roamzy doesn't close those traps — they don't exist in the product.
- No expiry on the balance. Loaded $50, used $12 on the first trip — the rest waits for the next one. Next year, the year after, still there.
- No auto-renewal. When the balance runs out, the eSIM stops. No background charge to a card you forgot about six months later.
- No throttling. One rate. The first GB and the hundredth cost the same $0.0046/MB.
It's not a marketing gimmick — it's an engineering decision born from indifference to gimmicks. You can't make a tariff cheaper than no fine-print and no expiry — so we don't.
What if the trail continues across borders?
South Asia tends to chain into Southeast Asia. Roamzy uses one rate per country, no manual switching at borders — the eSIM finds the network in the new country and bills at that country's rate:
- Thailand — common Bangkok onward via CMB
- Cambodia — connecting through Bangkok or Singapore
