You do not need to buy a local SIM card for every country on an international trip. A travel eSIM can provide mobile data as soon as you land, while your normal SIM remains available for calls and messages.
One important clarification: this is not a first-person device test. I have not personally tested these services on named phones, networks, or travel dates. The recommendations below are based on the providers’ current coverage, activation rules, hotspot policies, plan structures, and refund terms. Prices and policies can change, so check the destination-specific plan before paying.
My top eSIM recommendations for international travel
| Best for | Recommended eSIM | Why it stands out |
|---|---|---|
| Most travelers | Airalo | Broad coverage across more than 200 countries and regions, with regional and local plans. |
| Heavy data use | Holafly | Destination and regional plans marketed as unlimited, subject to fair-use and hotspot restrictions. |
| Long validity on fixed data | Saily | Some global data packages remain valid for up to 365 days. |
| Reusable eSIM and top-ups | Ubigi | The same eSIM can be reused in more than 200 destinations and topped up through the app. |
| Hotspot-friendly alternative | Nomad | Hotspot use is supported on most plans, although device and network stability vary. |
There is no universal cheapest eSIM. The real price depends on the country, number of days, data allowance, hotspot rules, and currency. A 1 GB plan for a short city break should not be compared directly with a 30-day unlimited plan.

Airalo is a good fit for normal travel use: maps, translation, messaging, ride-hailing, email, occasional browsing, and light social media. The main advantage is choice rather than a single unusually cheap package.
What to watch before installing
Do not assume that installing an Airalo package starts its validity period. For most packages, the clock starts when the eSIM connects to a supported network, but some packages begin when installed. In the Airalo app, check the package-specific rule at My eSIMs > Details > Show More > Validity Policy.
Airalo generally treats an installed eSIM as tied to the original device. It cannot normally be transferred to a replacement phone, so do not install it casually on a spare device.
Hotspot use is supported when both the device and network permit it. If the package requires a manual APN, enter the same APN in the Personal Hotspot APN field on an iPhone: Settings > Cellular/Mobile Data > Airalo eSIM > Cellular/Mobile Data Network.
Airalo refund edge cases
Airalo’s current terms say the consumer withdrawal period ends at the earlier of 14 days after purchase or activation. Service-failure requests generally need to be submitted within 30 days of the problem and may be limited to the unused portion.
For an eligible order, the in-account route is My eSIMs > [package] > Package History > Request Refund. Airalo also says an eSIM that has not been delivered within 70 minutes is automatically refunded.

2. Holafly: the best option for heavy data use
Holafly is aimed at travelers who do not want to monitor a small data allowance. Its destination and regional plans are marketed as unlimited, which can make them attractive for frequent video calls, navigation, uploads, and regular streaming.
“Unlimited” needs qualification. Holafly says network operators may apply fair-use speed reductions after high-speed usage. Hotspot availability and the amount of data you can share also vary by destination. An unlimited plan for one country may not offer the same tethering terms as an unlimited plan for another.
Check the technical specifications for the exact destination rather than relying on the word “unlimited” on the sales page.
Holafly’s separate subscription option
Holafly also lists an Unlimited global subscription at €59.95 per month, with 160-plus destinations and unlimited data sharing on the displayed plan. The subscription activates immediately after purchase and renews every 30 days. That makes it unsuitable for someone buying weeks ahead of a trip unless they deliberately want the service to start immediately.
For a normal destination plan, buy the number of days required, install the eSIM using the emailed instructions, and turn it on when you arrive. For the subscription, purchase close to the intended start date.

Saily is a strong choice when you prefer a fixed amount of data but want it to remain available for a long time. Its displayed Global plan included these prices when checked on August 8, 2026:

| Data | Validity | Displayed price |
|---|---|---|
| 1 GB | 7 days | $8.99 |
| 2 GB | 15 days | $16.49 |
| 5 GB | 60 days | $33.99 |
| 10 GB | 180 days | $56.99 |
| 20 GB | 365 days | $66.99 |
| 50 GB | 365 days | $129.99 |
The displayed Global plan covered 121 destinations. The 20 GB and 50 GB options are particularly useful for travelers taking several trips over a year, provided the destinations you need are included.
Saily activation and hotspot details
Saily says its Global plan activates automatically when you reach the destination, or 30 days after purchase. The eSIM must be enabled and data roaming must be turned on for it to connect. That 30-day fallback is important if you buy well before departure.
Saily provides a separate hotspot setup guide. Do not assume that tethering works identically in every country; check the individual plan and destination specifications.
Recommended Free Tools
Saily travel eSIMs are data-only. You can use WhatsApp, FaceTime, iMessage, Signal, and other internet calling services, but the eSIM does not normally provide a conventional cellular phone number for calls and SMS.
4. Ubigi: best reusable eSIM
Ubigi makes sense if you travel internationally more than once and want to keep one eSIM installed. The company says its eSIM can be reused in more than 200 destinations and topped up in the app without Wi-Fi or remaining data.
On the displayed World plans checked on August 8, 2026, Ubigi listed 10 GB for 30 days at $59 and a Best World unlimited plan for 30 days at $108. Prices can vary by destination, currency, and promotion.

- 【Upgrade Phones with eSIM Capability】The EIOTCLUB V3 physical eSIM card adds eSIM capabilities to unlocked iPhone and Android devices that have a physical SIM card slot, compatible with most models on the market.
- 【Direct iPhone Profile Management】This upgraded eSIM adapter lets users download, install and manage compatible eSIM profiles directly in the EIOTCLUB app. No card reader, computer or Android phone needed for profile management.

- 【Refillable & 1GB Global Data for Easy Start】Start with 1GB of prepaid global data, valid for 360 days in 200+ supported countries and regions. Stay connected during initial setup and profile downloads. After the included data is used or expires, choose from eligible EIOTCLUB data plans based on your needs.
- 【Automatic network backup for reliable connections】If a compatible profile cannot connect, this upgrated physical eSIM can restore the most recently working profile under supported conditions, helping simplify profile recovery.
Ubigi’s one-off plans use Smartstart: you can install the eSIM before leaving home, while the data-plan activation starts when you arrive in the destination. This is more convenient than a plan that starts at installation.
Using Ubigi as a hotspot
On an iPhone, select Ubigi for cellular data and then use Settings > Personal Hotspot. On a Samsung phone, the relevant paths are Settings > Connections > SIM card manager > Mobile data, followed by Settings > Connections > Mobile Hotspot and Tethering > Mobile Hotspot.
If the hotspot control is unavailable, Ubigi says the APN may need to be configured first. Its unlimited plans can also be subject to a fair-use policy, so heavy users should read the plan conditions.
5. Nomad: a good hotspot-friendly alternative
Nomad offers data-focused plans for many destinations and supports tethering on most eSIMs. It is a reasonable alternative when hotspot access matters but you would rather buy a defined data allowance than an unlimited plan.
Nomad does not support traditional voice calls or SMS. Hotspot performance is also not guaranteed across every phone and local network. On iPhone, the hotspot controls are under Settings > Mobile Data > Personal Hotspot. On Android, look under Settings > Connections or Network & Internet > Hotspot & Tethering.
Nomad’s refund policy is stricter after activation. Uninstalled or unactivated plans are generally fully refundable when requested within 30 days. An activated plan is treated as used, although a partial refund may be possible if a verified technical or network failure prevented service. Do not remove a single-use eSIM before requesting a refund, as that can make the request ineligible.

How to choose the right eSIM
- List every destination. A country plan may not cover a nearby country you visit for a day. For a multi-country trip, compare a regional or global package.
- Estimate your data. Maps and messaging use relatively little data; video calls, cloud backups, social video, and streaming can consume several gigabytes quickly.
- Decide whether hotspot is essential. Check the plan’s tethering terms, not just the headline data allowance.
- Check the activation trigger. Airalo rules vary by package, Saily has a destination or 30-day activation rule, Ubigi uses Smartstart on one-off plans, and Holafly’s global subscription starts immediately after purchase.
- Check the phone before buying. Confirm that it supports eSIM and is unlocked. On an iPhone, go to Settings > General > About > Carrier Lock. The desired result is No SIM Restrictions.
- Keep the installation email or QR code available. Install before departure when the provider allows it, but avoid turning on the travel line until you need it.
How to set up an international travel eSIM on an iPhone
- Confirm that the iPhone is an iPhone XS, iPhone XS Max, iPhone XR, or newer model, subject to regional and carrier limitations.
- Confirm Carrier Lock shows No SIM Restrictions under Settings > General > About.
- Buy the plan and follow the provider’s installation instructions while connected to Wi-Fi.
- Open Settings > Cellular and label the new line as Travel, Airalo, Holafly, Saily, Ubigi, or Nomad.
- Under Cellular Data, select the travel eSIM.
- Turn on data roaming for the travel eSIM if the provider requires it.
- Turn off data roaming for your home line, or disable the home line completely, to reduce the chance of roaming charges.
- At the destination, confirm that the travel line is enabled and that the phone has selected a supported network.
Only one line supplies cellular data at a time. You can keep the home line active for calls, iMessage, and FaceTime, but your carrier may charge for roaming if that line uses a foreign network.
Common eSIM mistakes that cause problems
- Buying before checking the lock status: an eSIM cannot bypass a carrier-locked phone.
- Assuming installation starts validity: activation rules differ by provider and package.
- Leaving the home SIM selected for data: the phone may continue using expensive roaming data.
- Calling every plan unlimited: fair-use speed limits and hotspot caps can apply.
- Expecting a phone number: Nomad, Ubigi, and Saily travel plans are data-only; use internet calling apps instead.
- Deleting an eSIM during troubleshooting: some single-use profiles cannot be reinstalled or transferred.
- Ignoring unusual destinations: China, in particular, has model- and region-specific iPhone eSIM restrictions. Check both Apple’s compatibility information and the provider’s destination coverage.
FAQ
Which eSIM is best for most international travelers?
Airalo is the best default recommendation because it offers packages in more than 200 countries and regions and provides local, regional, and global options. Check the specific package’s activation and hotspot rules before purchasing.
Is Holafly really unlimited?
Holafly markets many plans as unlimited, but its FAQ says network operators may apply fair-use speed reductions. Hotspot availability and sharing allowances also vary by destination.
Free tools Windows power users keep installed
One-click scans. No signup required.
Can I keep my normal phone number while using a travel eSIM?
Usually, yes. On a dual-SIM phone, you can keep the home line for calls and messages while selecting the travel eSIM for mobile data. Disable data roaming on the home line to help avoid extra charges.
How do I know whether my phone supports an eSIM?
On an iPhone, compatible models generally begin with the iPhone XS, XS Max, and XR, subject to region and carrier restrictions. Check Settings > General > About > Carrier Lock and confirm No SIM Restrictions. On Android, dialing *#06# and seeing an EID is a useful compatibility check, but the phone must also be unlocked and supported by the provider.
The Bottom Line
Choose Airalo for the safest all-round recommendation, Holafly when you need substantial data and accept fair-use and hotspot caveats, Saily for long-validity fixed data, Ubigi for a reusable travel eSIM, and Nomad when hotspot-friendly fixed data is the priority.
Before checkout, verify four things on the destination-specific page: coverage, activation timing, tethering rules, and refund conditions. Those details matter more than a provider’s headline data number.
