Where to buy an eSIM online in 2026

The easiest place to buy an eSIM online is a travel eSIM store: you pick a country, pay on the website, in an app or in a Telegram bot, and install the plan by QR code before you fly. On our shelf TonMobile leads with 9.3, because it sells in Telegram, on iOS and on Android and takes crypto next to cards. Airalo, Saily and Holafly follow with wider coverage claims of 200+ destinations.

Apple describes the same route in its own support pages: buy a prepaid plan from a local or worldwide provider's website or app before you leave, then activate it digitally. No shop counter, no plastic SIM and no queue at the airport.

What really differs between stores is not the idea but the fine print. One store takes PayPal, another takes Bitcoin. One refunds an unused plan within 30 days, another counts the package from the moment it activates. This page walks through those differences so you can pick where to buy before you pay.

Where to buy an eSIM online: the short list

Seven stores cover almost every way of buying a travel eSIM online. The table sums up how each one sells and what it is best at; the scores come from our full store rating, which explains every criterion.

Coverage figures are each store's own claim. TonMobile's website says 180+ countries, while its App Store and Google Play listings mention about 200 countries plus regional and global plans.

Three places that sell eSIMs online

Travelers buy eSIMs online through three channels. Each one differs in how you check out, how you pay and whether you need an account or documents.

Provider apps and websites

A travel eSIM provider resells local, regional and global mobile data plans as downloadable eSIM profiles. Airalo, Holafly, Saily, Nomad, Ubigi and Yesim all work this way. You choose a destination, pay by card or wallet and get a QR code or an in-app install button.

This is the most common way to buy. The trade-off is that payment options are mostly the same across stores: cards, Apple Pay, Google Pay and, at several of them, PayPal.

Store bots inside Telegram

A Telegram store bot is a shop that runs inside the messenger, so the whole purchase happens in a chat. TonMobile sells this way through the @tonmobile bot, which showed 29,857 monthly users on October 27, 2026. The same store also has iOS and Android apps for people who prefer a regular app.

Telegram checkout suits travelers who already live in the app or want to pay with Toncoin. Our guide on buying an eSIM in Telegram covers the steps and how to spot a fake bot.

Your carrier's website

A carrier eSIM moves your existing home number onto the eSIM chip, so the carrier usually asks you to sign in to your account first. It is the right choice when you change phones at home. Abroad it runs on your carrier's roaming terms, which is the cost a travel eSIM is meant to avoid; TonMobile, for example, says its plans cost up to 5 times less than roaming.

What you need before you buy

A travel eSIM works only on a phone that has an eSIM chip and is not locked to a carrier. Checking both takes two minutes and saves a refund request later.

• An eSIM-capable phone: iPhone XS, XR or later, or an Android phone that shows an EID.
• A carrier-unlocked phone, because a locked phone refuses profiles from other providers.
• Wi-Fi or another connection for the install: Apple requires one to download the eSIM profile.
• A payment method the store accepts, from cards to PayPal or crypto.
• Your destination and trip length, so you can choose between a fixed pack and unlimited data.

Our step-by-step guide on checking eSIM support on any phone goes deeper, including what to do if the check fails.

How you can pay: cards, PayPal or crypto

Every store on our shelf accepts cards and mobile wallets, but only some accept PayPal, and only TonMobile accepts crypto. Payment is often the deciding factor when your card is declined abroad or you prefer not to share card details.

Paying with crypto has its own rules for refunds and fees. TonMobile returns crypto refunds within up to 5 business days, while network fees stay with the buyer. The full walk-through is in our guide on buying an eSIM with crypto.

The stores, one by one

Each store below is described with the same facts: what it is, how you buy, how you pay, and what to watch out for. All numbers are the store's own claims from its website, terms or app listing.

1. TonMobile: buy in Telegram, pay with cards or crypto

TonMobile is a travel eSIM service that sells data plans for 180+ countries through a Telegram bot, an iOS app and an Android app. Its terms name the operator: Intermob Limited, a Hong Kong company that took over the service from Tonave Services Limited on September 23, 2026.

TonMobile describes its flow in three steps: open the store in Telegram, the App Store or Google Play, choose a country and plan, then install the eSIM in a couple of taps. The apps add top-ups for an existing eSIM, a view of remaining data and validity, gifting, bulk purchases and cashback, according to the App Store listing.

The store takes Visa, Mastercard, Apple Pay, Google Pay, Bitcoin and TON, and it states that no documents are required to buy. Current prices are published on the TonMobile price page; we do not quote them here because they change by destination.

2. Airalo: a large marketplace of plans

Airalo is a travel eSIM marketplace that claims 200+ locations and 30M+ customers. It sells local, regional and global plans, both fixed and unlimited: a Turkey unlimited plan starts at $11.50 for 3 days, regional plans from $5.00 for Europe and global plans from $8.50.

Checkout takes Visa, Mastercard, Amex, UnionPay, JCB, PayPal, Apple Pay, Google Pay and Alipay in the app. Hotspot works when the device and network allow it. The catch sits in refunds: a wrong purchase or change of plans comes back as Airmoney credit, not as money.

3. Saily: small packs from the NordVPN company

Saily comes from Nord Security, the company behind NordVPN and NordPass, and claims over 200 destinations. Its fixed packs start small: Turkey 1 GB for 7 days costs $3.99. An optional US phone number for calls and texts costs $1.99 a month and requires ID verification.

Saily refunds a plan in full within 30 days if it was not installed or activated. After activation, a refund is only considered for quality issues or when more than 99% of the data is unused.

4. Holafly: unlimited data by the day

Holafly sells unlimited data by the number of days, from 1 to 90, and monthly subscriptions from $49.90. A Turkey plan costs $11.90 for 3 days and $73.90 for 30 days. Per-trip plans are data-only and share up to 1 GB of hotspot per day.

Holafly accepts Visa, Mastercard, Google Pay, Apple Pay and PayPal. Refunds for incompatible devices, cancelled trips or connection issues go back to the original payment method in 3 to 5 business days.

5. Nomad: a free trial and a monthly pass

Nomad claims 200+ destinations with plans starting from $4.50, a free 1 GB trial and a Nomad Pass from $4.08 a month with always-on data. It accepts major cards, Apple Pay, Google Pay and PayPal. Refund requests are accepted within 30 days, but unlimited plans are excluded.

6. Yesim: pay as you go

Yesim is run by Genesis Group AG in Switzerland and claims over 200 destinations. It sells an unlimited day pass from $2.98 a day and Pay & Fly data from $1.10 per GB, with hotspot included at no extra fee. Unused plans and top-ups can be refunded within 30 days.

7. Ubigi: a carrier brand for travelers

Ubigi is a brand of Transatel, part of the NTT group. It sells one-off, monthly and annual plans from 500 MB for 30 days at $5 up to unlimited plans for 8, 15 or 30 days, with tethering allowed on every plan. Refund requests must come within 14 business days of purchase.

How to buy an eSIM online, step by step

Buying an eSIM online takes five steps, and the order matters more than the store. Install early, switch on late.

1. Check the phone

   Confirm the phone shows an EID and is carrier-unlocked. On an iPhone the carrier lock field sits in SettingsGeneralAbout.

2. Pick the store and the plan

   Choose the destination, then a fixed data pack or an unlimited plan for the length of the trip.

3. Pay

   Use a card, Apple Pay or Google Pay anywhere; PayPal at six stores; Bitcoin or TON at TonMobile.

4. Install on Wi-Fi

   Scan the QR code or tap the in-app install button. Apple requires a Wi-Fi or hotspot connection for this step.

5. Switch on after landing

   Select the travel eSIM as the data line, for example in SettingsCellularCellular Data on an iPhone, and turn on data roaming for that line.

After the trip, Apple recommends checking that Turn On This Line is enabled for your home line and turning off travel lines you no longer use.

Refund rules: what you can get back

Every store on our shelf has a written refund rule, but the windows and conditions differ a lot. TonMobile accepts requests within 180 days of purchase while the package is still valid; Ubigi allows 14 business days.

Two things are never refundable at TonMobile: a profile you deleted yourself and one you installed incorrectly. The full comparison is in our guide to eSIM refund policies.

Unlimited or a fixed data pack?

An unlimited plan makes sense for navigation, video calls and hotspot use on short trips; a fixed pack is cheaper when you mostly message and check maps. "Unlimited" rarely means full speed forever.

Hotspot rules differ too: Holafly caps per-trip hotspot at 1 GB per day, while Ubigi allows tethering on all plans. Our guide on what unlimited really means compares the rules store by store.

Is it safe to buy an eSIM online?

Buying an eSIM online is safe when the store publishes who runs it, its terms and a refund policy. All seven stores on our shelf name their company or parent, from Intermob Limited at TonMobile to Nord Security at Saily and Transatel at Ubigi.

• Buy from the store's official website, its App Store or Google Play listing, or the bot handle linked from its own site.
• Check app ratings and their count: Holafly shows 4.8 from 41K App Store ratings, TonMobile 4.5 from 162 Google Play reviews.
• Read the refund rule before paying, especially credit-only refunds such as Airalo's for a change of plans.
• Keep the QR code to yourself and do not delete the installed profile.

Common mistakes when buying an eSIM online

Most failed eSIM purchases come down to the phone or the timing, not the store.
