Airalo averages $4.50/GB across 200+ countries. Per-country pricing varies: Japan eSIMs start around $4.00/GB across all providers, while Thailand eSIMs drop below $2.50/GB on Nomad.

Unlimited data eSIM: Holafly pricing and fair-use rules

Holafly is the only provider offering unlimited daily data plans. Pricing starts at $2.99/day for 5-day plans and scales down on longer trips. A 15-day plan in Europe costs about $40, which works out to $2.67/day. Holafly covers 178 countries.

Fair-use policy:Holafly does not publish an exact daily data cap, but users report throttling after 2 to 3 GB of high-speed data per day. After the threshold, speeds drop to 512 kbps. This is still 2x faster than T-Mobile's free international data (256 kbps). For heavy streamers, the throttled speed supports standard-definition video and voice calls.

Tethering: Most Holafly plans restrict hotspot tethering to about 1 GB per day. Tethering a laptop for video calls will hit this cap fast. If you need heavy tethering, a per-GB eSIM from Airalo or Nomad with a larger data allowance provides more consistent speeds.

How we score and rank eSIM providers

Our ranking uses five criteria, each scored on a 1 to 5 scale. The overall rank is a weighted average. Here is the methodology:

• Coverage (25% weight): Number of countries and destination variety. Data sources: provider websites and our destination testing across 40 countries
• Speed (20% weight): Network quality based on carrier partners in each country. We identify which local carriers each provider connects to and cross-reference with GSMA speed data
• App quality (20% weight): App Store and Google Play ratings, plus our hands-on testing of eSIM installation, data tracking, and plan management features
• Pricing (20% weight): Cost per GB or per day across 10 benchmark destinations (Japan, Thailand, UK, France, Mexico, Australia, Italy, Germany, South Korea, Turkey). We compare apples-to-apples on 5 GB / 7-day plans
• Support (15% weight): Response time and channel availability. We contact each provider with a test question and measure time to resolution. Channels scored: live chat (best), email (good), no real-time option (lower)

We re-check pricing and carrier partnerships every month. Scores last updated June 2026. We do not accept payment or sponsorship from any eSIM provider. All eSIM plans used in testing are purchased at retail price.

How to choose the right eSIM provider

• Heavy data user (streaming, video calls): Holafly unlimited plans
• Multi-country trip: Airalo regional bundles (Eurolink, Asialink)
• Privacy-focused: Saily with built-in NordVPN
• Budget trip to Southeast Asia: Nomad for lowest per-GB price
• First-time eSIM user: Airalo for the highest-rated app (4.8/5) and widest support

eSIM vs carrier roaming: how much you save

The price gap between carrier roaming and a travel eSIM is the core reason travelers switch. Here is a side-by-side comparison for a 7-day trip using 5 GB of data:

eSIM prices vary by destination. AT&T and Verizon rates verified June 2026.

The bottom line: a travel eSIM saves $48 to $61 per person per week compared to AT&T or Verizon. For a couple traveling together, the savings double to $96 to $122. See the full carrier-by-carrier breakdown.

Regional and global eSIM bundles for multi-country trips

If your trip covers multiple countries, a regional or global eSIM bundle is cheaper than buying separate country plans. Airalo offers the widest selection:

• Eurolink: 39 European countries on one plan. 5 GB for $18. Covers EU + UK + Switzerland + Turkey
• Asialink: 16 Asian countries. 5 GB for $20. Covers Japan, South Korea, Thailand, Indonesia, Vietnam, and more
• Discover Global: 130+ countries on one eSIM. 5 GB for $35. Best for round-the-world trips
• Holafly Europe: Unlimited data in 30+ EU countries from $2.99/day. No per-GB counting across borders

Buying a regional bundle vs. individual plans saves 20% to 40% on a 3-country trip. A traveler visiting France, Italy, and Spain can use a single Eurolink plan instead of buying three separate eSIMs.

What to check before buying a travel eSIM

Not all eSIM plans are equal. Before purchasing, verify these five details:

1. Your phone supports eSIM.Check Settings > Cellular on iPhone or Settings > Network on Android. Compatible models: iPhone XR+, Samsung Galaxy S20+, Google Pixel 3+, and most 2022+ Android flagships.
2. Your phone is not carrier-locked. Carrier-locked phones may block third-party eSIM profiles. Contact your carrier to confirm SIM-free status.
3. The plan covers your destination.Check the provider's country list. Airalo covers 200+ countries. Holafly covers 178. Saily covers 150. Nomad covers 112.
4. Data allowance fits your usage. Light users (email, maps, messaging): 1 to 3 GB per week. Moderate users (social media, web browsing): 3 to 5 GB per week. Heavy users (streaming, video calls): 5 to 10 GB per week, or Holafly unlimited.
5. Activation timing matches your trip. Some eSIMs activate on install (the data clock starts ticking). Others activate on first use in the destination country. Install early, but check the activation policy.

How much eSIM data do you need for travel

The right plan size depends on how you use your phone. Here is a breakdown by traveler type, based on daily data usage patterns:

Most travelers fall in the moderate category. A 5 GB eSIM plan covers a full week of navigation, social media posting, email, and daily WhatsApp messaging. If you plan to stream video or join Zoom calls daily, choose a 10 GB plan or Holafly's unlimited option.

Will a travel eSIM work with my phone

Travel eSIMs work with any SIM-free phone that has eSIM hardware. Compatible phones include:

• Apple: iPhone XR, XS, 11, 12, 13, 14, 15, 16 and all Pro/Max variants
• Samsung: Galaxy S20, S21, S22, S23, S24, S25, Galaxy Z Flip 3+, Galaxy Z Fold 3+
• Google: Pixel 3, 3a, 4, 4a, 5, 5a, 6, 6a, 7, 7a, 8, 8a, 9
• Other: OnePlus 12, Motorola Razr 2023+, Microsoft Surface Duo 2, OPPO Find X5+

Phone must be SIM-free.Carrier-locked phones from AT&T, Verizon, or T-Mobile may block third-party eSIM profiles. Call your carrier or check Settings > General > About (iPhone) to confirm your phone has no SIM restrictions before purchasing a travel eSIM.
