Region matrix
Provider coverage by region
Estimated country coverage per provider per region. Based on total countries in our database and each provider's overall coverage percentage.
| Region | Countries | HelloRoam | Airalo | Holafly | Nomad | Saily |
|---|---|---|---|---|---|---|
| Europe | 51 | ~48 | ~43 | ~37 | ~28 | |
| Africa | 50 | ~48 | ~43 | ~36 | ~27 | |
| Asia | 33 | ~31 | ~28 | ~24 | ~18 | |
| Caribbean | 26 | ~25 | ~22 | ~19 | ~14 | |
| South America | 13 | ~12 | ~11 | ~9 | ~7 | |
| Middle East | 12 | ~11 | ~10 | ~9 | ~6 | |
| Oceania | 9 | ~9 | ~8 | ~6 | ~5 | |
| Central America | 7 | ~7 | ~6 | ~5 | ~4 | |
| North America | 4 | ~4 | ~3 | ~3 | ~2 | |
| Other | 4 | ~4 | ~3 | ~3 | ~2 |
Airalo leads in every region. The gap between Airalo and Nomad is widest in Africa and the Caribbean. For popular tourist regions (Europe, Southeast Asia), all five providers cover the major destinations. Niche destinations in Central Asia and the Pacific require checking provider coverage before purchasing.
5G coverage
5G availability by region
5G is expanding but not universal. Most eSIM plans connect to 4G LTE. 5G access depends on the specific plan and destination.
| Region | 5G markets | Notable countries |
|---|---|---|
| Europe | 25+ | UK, Germany, France, Spain, Italy, Netherlands, Switzerland |
| Asia | 15+ | Japan, South Korea, China, India, Thailand, Singapore |
| North America | 3 | USA, Canada, Mexico (limited) |
| South America | 5 | Brazil, Chile, Colombia, Argentina, Peru (limited) |
| Middle East | 8 | UAE, Saudi Arabia, Qatar, Bahrain, Kuwait, Israel |
| Africa | 4 | South Africa, Kenya (limited), Nigeria (limited), Egypt (limited) |
| Oceania | 2 | Australia, New Zealand |
| Caribbean | 1 | Puerto Rico (via US carriers) |
Europe and East Asia have the most widespread 5G coverage. Africa and the Caribbean have minimal 5G deployment. Most eSIM plans default to 4G LTE, with 5G where the local carrier has deployed it. 5G on eSIM is a bonus, not a baseline expectation.
Gap analysis
Coverage gaps by provider
Where each provider's coverage falls short. The delta between providers matters for off-the-beaten-path destinations.
| Provider | Total countries | Notable missing | Gap regions |
|---|---|---|---|
| Airalo | 200 | A few Pacific islands, some micro-states | Minimal gaps. Broadest footprint. |
| Holafly | 160 | Several African nations, Central Asian republics, some Pacific islands | Africa (-15 vs Airalo), Central Asia (-5) |
| Saily | 200 | Large parts of Africa, Central Asia, Caribbean islands, Pacific islands | Africa (-30 vs Airalo), Caribbean (-10) |
| Nomad | 200 | Most of Africa, Central Asia, South America (partial), Pacific islands, Caribbean | Africa (-50 vs Airalo), South America (-15), Caribbean (-15) |
The 40-country gap between Airalo (200) and Holafly (160) consists mostly of African nations, Central Asian republics, Caribbean islands, and Pacific island states. For mainstream travel to Europe, Asia, and the Americas, all five providers cover the major destinations. The gap only matters if your itinerary includes less-visited countries.
Regional bundles
Multi-country bundle coverage
Regional bundles let multi-country travelers use one eSIM across multiple destinations. Not all providers offer them.
| Provider | Bundle name | Countries | Type | Price range |
|---|---|---|---|---|
| HelloRoam | Europe | 32 | Regional (Europe) | Not published |
| Airalo | Eurolink | 39 | Regional (Europe) | $5-$50 (1GB-20GB) |
| Airalo | Asialink | 16 | Regional (Asia) | $5-$40 (1GB-20GB) |
| Airalo | Discover Global | 130 | Global | $15-$100 (1GB-20GB) |
| Holafly | Europe unlimited | 32 | Regional (Europe) | $2.99/day unlimited |
| Holafly | Asia unlimited | 12 | Regional (Asia) | $2.99/day unlimited |
| Nomad | Single country only | 1 | Country-specific | Varies by country |
| Saily | Single country only | 1 | Country-specific | Varies by country |
Bundles by provider: HelloRoam (Europe), Airalo (Eurolink, Asialink and Discover Global) and Holafly (Europe unlimited and Asia unlimited). Nomad and Saily sell single-country plans only. No bundle covers every destination on this page, and the country lists differ, so check the one you are offered against your itinerary before buying.
Coverage depth
Rural vs urban coverage
eSIM providers do not control tower placement. Coverage depth depends on the local carrier's infrastructure.
Urban areas
All five providers deliver reliable 4G LTE in major cities worldwide. Urban coverage is dense, with multiple carrier towers per square kilometer. Coverage is strongest in cities like Tokyo, London, Bangkok, and New York.
Provider choice in urban areas comes down to pricing and features, not coverage quality. All five work well in cities.
Rural areas
Rural coverage depends on the destination country's carrier infrastructure. Developed nations (Japan, UK, Germany) have strong rural 4G. Developing nations may drop to 3G or 2G outside cities.
The eSIM provider assigns you to a local carrier. If that carrier has poor rural coverage, your connection suffers regardless of which provider you chose. Check the destination country's carrier coverage maps before traveling to remote areas.
Key takeaway
eSIM coverage equals the local carrier's coverage map. No eSIM provider can deliver connectivity where no cell tower exists. For mainstream tourism (cities, resorts, highways), all five providers deliver strong connectivity. For wilderness trekking, safari routes, or remote island hopping, download offline maps before leaving a coverage area.

FAQ
eSIM coverage FAQ
Which eSIM provider covers the most countries?
Which eSIM provider covers the most countries?
Airalo covers 200+ countries, the widest footprint among travel eSIM providers. Saily and Nomad each cover 200. HelloRoam covers 186. Holafly covers 160, the narrowest of the five. The gap matters most for Africa, Central Asia, and Pacific island destinations where Holafly has the fewest options. For popular tourist destinations in Europe, Asia, and the Americas, all five providers have overlapping coverage.
Does eSIM coverage mean 5G everywhere?
Does eSIM coverage mean 5G everywhere?
No. eSIM coverage means a data connection is available. The network type depends on local carrier infrastructure. 5G is available in 60+ countries as of 2026, concentrated in Europe, East Asia, and North America. Most eSIM plans connect to 4G LTE. 5G availability on eSIM plans is not guaranteed even in 5G countries. Check the specific plan details for each destination.
Does eSIM work in rural areas?
Does eSIM work in rural areas?
eSIM connects to local carrier towers. Rural coverage depends on the carrier's infrastructure in that area, not the eSIM provider. In developed countries (UK, Japan, South Korea), rural 4G coverage is strong. In developing countries (parts of Africa, Southeast Asia, South America), rural coverage may drop to 3G or 2G. The eSIM provider has no control over tower density. Check the destination country's carrier coverage map before relying on eSIM in remote areas.
Can I use a regional bundle instead of a single-country plan?
Can I use a regional bundle instead of a single-country plan?
Yes, if your provider offers regional bundles. Airalo offers Eurolink (39 European countries), Asialink (16 Asian countries), and Discover Global (130 countries). Holafly offers regional unlimited plans for Europe and Asia. Saily and Nomad are single-country only. Regional bundles use one eSIM profile across multiple countries. No switching needed at borders. Per-GB cost is usually higher than single-country plans but lower than buying separate plans for each stop.
What happens if my destination is not covered by my eSIM provider?
What happens if my destination is not covered by my eSIM provider?
The eSIM will not connect. You will have no data. Options include: switch to a provider that covers the destination (Airalo covers 200+ countries), buy a local SIM card at the airport, or rely on WiFi. Check coverage before you travel. Each provider lists supported countries on their website and app. For obscure destinations, verify coverage before purchasing.
Common eSIM Questions

Apple Watch Series 3 and later support eSIM for cellular connectivity. Travel eSIM providers do not support Apple Watch directly. Apple Watch eSIM requires a carrier plan (AT&T, T-Mobile, Verizon, EE, Vodafone). Number sharing with your iPhone plan costs $5-10/month.

eSIM not working: 1) enable data roaming in settings, 2) verify your device supports eSIM (iPhone XS or later, most 2020+ Android phones), 3) check carrier coverage in your area, 4) toggle airplane mode on and off, 5) reset network settings. Contact your eSIM provider if activation fails.
