Network coverage
South Asia mobile network overview
South Asia presents the most complex regulatory environment for eSIM travelers. India, the region's largest market, requires IMEI registration for all mobile devices. Not all international eSIM providers have completed the regulatory steps needed to operate in India, so plan availability is narrower than in Europe or Southeast Asia. Sri Lanka, Nepal, and Bangladesh support travel eSIMs but offer fewer plan options.
Network quality in India is strong where it matters for tourists. Jio and Airtel compete on 4G and 5G in Delhi, Mumbai, Bangalore, Chennai, and Kolkata. Coverage drops in the Himalayas, hill stations, and rural areas. The Maldives has strong resort-area coverage from Dhiraagu and Ooredoo but limited connectivity outside Male. Nepal's Kathmandu valley has reliable 4G, while trekking routes above 3,000 meters rely on satellite or nothing.
Carrier roaming in South Asia costs the same flat rate as every other region: AT&T at $12/day, Verizon at $12/day. T-Mobile's included data, at up to 256Kbps past its 5GB or 15GB allowance, works for basic messaging but cannot load India's data-heavy apps like Google Maps in congested traffic or stream video at any watchable quality.
Pakistan has improving 4G coverage in Lahore, Islamabad, and Karachi through Jazz and Zong, but eSIM plan availability remains limited compared to India. Bhutan has minimal international eSIM support. The Maldives charges premium rates for data at resorts. Neither resort pricing nor local prepaid pricing is tracked on this site, so no saving percentage is published for it; the eSIM rate itself is on the Maldives destination page.
Travelers crossing between India and Sri Lanka, or combining India with Nepal and the Maldives, should consider per-country eSIM plans rather than regional bundles. South Asia regional bundles have limited options compared to Europe or Asia regional plans.
India's 5G expansion has changed the eSIM calculus for metro travelers. As of June 2026, Jio and Airtel have 5G coverage in Delhi, Mumbai, Bangalore, Chennai, Hyderabad, and Kolkata. Travelers in secondary cities and tourist destinations outside the major metros get 4G LTE.
The Maldives requires pre-flight eSIM installation. Resort WiFi costs $10-20/day and is usually slow and shared. The seaplane transfer from Male to outer atolls has unreliable WiFi — install the eSIM at Male airport before boarding. Pre-installation takes two minutes.
Nepal above 3,000 meters has no mobile coverage from any carrier or eSIM provider. Above Lukla on the Everest route — the most popular trekking area — there is no signal. Download Gaia GPS or Maps.me with the Nepal offline pack before departing Kathmandu.
Regional overview
eSIM and roaming in South Asia
South Asia presents unique challenges for eSIM travelers. India, the region's largest market, requires IMEI registration for all mobile devices and has complex telecom regulations that limit some eSIM providers. Not all international eSIM services work in India: check provider compatibility before your trip. Sri Lanka, Nepal, and Bangladesh have growing eSIM support but fewer plan options compared to mainstream tourist destinations. The average eSIM price across 8 South Asian countries is $3.06/GB. Network quality in India is strong in urban areas where Jio and Airtel compete aggressively on 4G/5G, but rural and mountainous coverage (Himalayas, hill stations) remains patchy. The Maldives has excellent resort-area coverage but limited options outside Male. Pakistan has improving 4G coverage in major cities but eSIM plan availability is limited compared to other regions.

Our analysis
Best eSIM provider for South Asia: Airalo
Airalo is the only major eSIM provider with dedicated plans covering India, Sri Lanka, Nepal, and the Maldives.

Data tips
Staying connected in South Asia
Practical advice for managing data and connectivity across South Asia.
India's navigation and ride-hailing apps (Google Maps, Uber, Ola) consume more data than you expect. Budget 1-2 GB/day if you rely on ride-hailing in cities.
Nepal trekking routes above Lukla and Jomsom have zero mobile coverage. Download offline maps and inform your accommodation of your route before heading out.
The Maldives resort WiFi is often slow and expensive ($10-20/day). A travel eSIM on Dhiraagu's network delivers better speeds at lower cost.
Indian 5G is expanding fast in metro areas. If your phone supports 5G and your eSIM provider offers it, you will get 5G in Delhi and Mumbai.
WiFi quality
WiFi and connectivity in South Asia
South Asian WiFi is inconsistent outside major hotel chains and co-working spaces.
- Indian luxury hotels offer reliable WiFi. Budget hotels and guesthouses have slower, shared connections that drop during peak hours.
- Maldives resort WiFi is expensive ($10-20/day) and often slower than a mobile eSIM connection on Dhiraagu's network.
- Nepal's Kathmandu and Pokhara have cafe WiFi. Trekking lodges above base camp have no WiFi and no mobile coverage.

How much does an eSIM cost in South Asia?

Is an eSIM cheaper than roaming in South Asia?
Yes. AT&T International Day Pass charges $12/day and Verizon TravelPass charges $12/day for roaming in South Asia. T-Mobile's Experience plans include 5GB or 15GB of high-speed data abroad, then up to 256Kbps, while eSIMs deliver full 4G/5G speeds.
Do I need to register my phone's IMEI for India?
India requires IMEI registration for all mobile devices, but most international eSIM providers handle this automatically as part of their activation process. Verify your chosen provider supports India before purchasing. If you plan to stay longer than 90 days or buy a local SIM, you will need to register your IMEI separately through the Indian government's portal.
Does eSIM work in the Maldives resort islands?
Yes. Dhiraagu and Ooredoo cover the main resort islands and Male with 4G service. Resort reception desks price data separately and this site tracks no figure for them, so no percentage is quoted here. What is priced is the eSIM: see the Maldives destination page for the current per-gigabyte rate. Install your eSIM before you fly to the Maldives, since Male airport WiFi can be slow.
Can I use eSIM while trekking in Nepal?
Only in lower-altitude areas. NTC and Ncell cover Kathmandu, Pokhara, and the initial stages of popular trekking routes (Annapurna Circuit, Everest Base Camp). Coverage drops above 3,000 meters. Namche Bazaar has intermittent coverage. Above Lukla, expect no mobile signal. Download offline maps and carry a satellite communicator for high-altitude trekking.
Which Indian cities have 5G eSIM coverage?

AT&T charges $12/day in India. A 10-day India trip costs $120 in AT&T roaming.
What eSIM works best for India?
Airalo is the most reliable choice for India. Airalo has completed India's IMEI registration requirements and partners with Jio and Airtel for 4G/5G access in major metros. Not all eSIM providers support India — verify compatibility before purchasing. Nomad's India coverage is more limited than Airalo or Holafly.
Does eSIM work in Sri Lanka?

How we checked these rates
Carrier roaming rates were read from AT&T, Verizon, T-Mobile, Vodafone UK, and EE official rate cards and websites in June 2026. Destination plan prices come from HelloRoam's catalogue, read 29 Oct 2026, and destinations outside it keep their earlier record. Per-GB averages are calculated from the cheapest available plan per country. The 1-day unlimited price is the 1-day tier in that catalogue. All prices are in USD unless stated otherwise. Rates checked June 2026.
Is eSIM cheaper than international roaming?
Yes, a travel eSIM is 70-90% cheaper than carrier roaming for international trips. AT&T and Verizon charge $12/day for international data, totaling $84-168 for a 7-14 day trip. A travel eSIM on the same local network costs $5-25 for the same period. Both connect to the same cell towers in the destination country. The eSIM removes the carrier markup.

This setup saves 70-90% vs carrier roaming on the same network.
