Where to buy a travel eSIM online: options, payment and checks

Where to buy an eSIM for travel: how a travel eSIM differs from a carrier eSIM, how to buy one online, what to check before you pay and how to read reviews.

The easiest way to buy an eSIM for travel is online: on a travel eSIM provider’s website or in its Telegram bot, from home, before your flight. You pick a country and a plan, pay, and get a QR code that installs the profile on your phone as a second line. A carrier eSIM from your home provider won’t do this job: it’s your phone number, not a data plan for a trip.

Where can you buy an eSIM? Three very different options

You can buy an eSIM from three kinds of sellers, and each gives you something different. Your home carrier issues an eSIM with your own number. A travel eSIM provider sells a data plan for your trip. A carrier in your destination sells a local eSIM, but usually only once you’re there.

An eSIM from a Russian carrier like MTS, Beeline or MegaFon is your Russian number without the plastic card, and abroad it runs on that carrier’s roaming. The rest of this article is about the travel eSIM: what people usually mean when they search for “buy eSIM for travel” or “eSIM for international travel”.

How to buy a travel eSIM online, step by step

Buying a travel eSIM online takes a few minutes, and most sellers follow a similar flow. With MoreSim, which sells travel eSIMs for 200+ destinations on its website and in the Telegram bot @moresim_bot, it goes like this.

1. Open the MoreSim website or the bot @moresim_bot. The bot has a built-in phone compatibility check, so run it before you buy.
2. Choose your destination country or region.
3. Pick a plan by data amount and validity; the options for each country are on its catalog page. Our guide on how much data you need for a trip helps you estimate it.
4. Pay with Telegram Stars from any country, right in the bot; bank card and SBP payments currently work with cards issued in Russia.
5. Get your QR code: it arrives in the chat in about 30 seconds.
6. Install the profile at home over Wi-Fi and give the line a label, like “Turkey”.
7. After landing, set the eSIM as your mobile data line and turn on data roaming for it: most travel eSIMs run on a local carrier’s network as roaming. The plan starts counting on first connection in the destination.

Buying early is safe: until you connect to a network in your destination, no days of the plan are used up. Step-by-step installation for iPhone and Android is in our MoreSim install and activation guide, and buying through the bot is covered in its own article.

What to check before you buy an eSIM

Before you buy a travel eSIM from any seller, check seven things: phone compatibility, carrier lock, the countries on your route, data and validity, when the clock starts, top-ups and support. Almost every problem on the road traces back to one of them.

• Phone compatibility. Your model needs to support eSIM, and so does your exact version: some models are sold without eSIM in certain markets.
• Carrier lock. A phone locked to one carrier may refuse another provider’s profile.
• Country or region. Make sure every country on your route is included in the plan, including layovers where you’ll leave the airport.
• Data and validity. Compare them with the length of your trip and how much you use data away from Wi-Fi.
• When the clock starts. From purchase, from installation or from first connection in the destination: this makes a big difference to planning.
• Top-ups. Can you add data to the same profile, or will you need a new eSIM?
• Support. Where and in which languages they reply if something stops working on the road.

If you’re unsure which plan to pick, go through our checklist for choosing a travel eSIM. And if your route covers several countries, our global eSIM guide explains when a regional plan beats a plan for each country.

Which eSIM is best? How to read reviews and rankings

eSIM reviews are only useful when you know exactly what they describe. A traveler’s experience in one country says almost nothing about coverage in another, and a complaint about an old phone model may not apply to yours. So when you search for “eSIM reviews” or “best travel eSIM”, look past the overall tone and focus on the details.

• How recent it is. Terms, networks and apps change, so a two-year-old review tells you little.
• Country and place. A city, a resort, the mountains and the coast are different conditions even within one country.
• Phone model. Many problems come down to settings on a specific model, not the seller.
• What the complaint really is. “No internet” and “forgot to turn on data roaming for the eSIM” are often the same story.
• How support responds. You can test how fast and helpful they are yourself by asking a question before you buy.

Rankings of the “best eSIMs” without clear criteria aren’t worth much: if they don’t say what was compared and how, it’s just a list. It’s more reliable to vet the seller yourself: does your phone support eSIM, is your country in the plan, when does the clock start, how do they take payment and how fast does support reply.

How to pay for an eSIM: card, SBP and Telegram Stars

Payment options depend on the seller, so check them before you pick a plan. MoreSim takes payment in Telegram Stars from any country, right in the bot @moresim_bot, while bank card and SBP payments, on the website and in the bot, currently work with cards issued in Russia. Travelers paying from Russia will find the details, and what to do if a payment fails, in our separate guide.

To avoid overpaying, choose a plan for how you’ll actually use your phone rather than with a huge safety margin. If you run out of data early, you can top up a MoreSim plan without a new eSIM: use “Top up data” on the eSIM card in your account or in the bot’s app, if top-ups are available for that plan.

“Activated eSIM” and “eSIM with a number”: what they really mean

There’s no need to hunt for an “already activated” travel eSIM: you get a QR code, install the profile yourself, and a MoreSim plan starts working on first connection in the destination. Secondhand offers of “activated eSIMs” usually mean someone else’s profile or QR code, so treat them with caution.

A travel eSIM gives you data, and a phone number is a separate product. MoreSim plans are mobile data only, with no phone number; the data and validity for each country are on its catalog page. You can call over messaging apps where they aren’t restricted, and bank texts keep arriving on your home SIM. A number from your home country on an eSIM comes from your own carrier.

What mistakes should you avoid when buying an eSIM?

Two mistakes come up more than any others: buying a secondhand QR code and deleting the profile before the trip is over. Either way, the profile usually can’t be installed again from the same QR code.

If something goes wrong after you buy, MoreSim support is available via /support in the Telegram bot @moresim_bot, a ticket in your account and email. Send your phone model and a screenshot of your cellular settings to get it sorted faster.
