Basics
Types of eSIM: carrier, travel, local, wearable and adapter
The types of eSIM: your carrier’s eSIM with your number, a travel eSIM for data, a local eSIM, eSIM in watches and tablets, and eSIM adapters. A comparison table and how to choose.
There are five types of eSIM by purpose: your carrier’s eSIM with your number, a travel eSIM for data on a trip, a local eSIM from a carrier in another country, eSIM in watches and tablets, and an eSIM adapter for phones without a built-in eSIM. Technically, they’re all the same digital profile on an eUICC chip. What differs is who issues it, what it gives you and where it works.
Types of eSIM at a glance: comparison table
All types of eSIM are easy to compare on three points: whether the profile gives you a number, where it works and where you get it.
| Type of eSIM | Number | Where it works | Where to get it | Who it’s for |
|---|---|---|---|---|
| Carrier eSIM | Yes, your number | At home; abroad on roaming | Carrier store, website or app | Anyone who wants their number without a plastic card |
| Travel eSIM | Usually no; some plans include a number | In the destination country or region | Online from travel eSIM sellers | Travelers who need mobile data |
| Local eSIM | Usually yes, a local one | In that country | From the country’s carrier; rules for foreigners vary | Long-stay visitors |
| eSIM in watches and tablets | Watch — linked to your number; tablet — its own plan | Wherever the issuing carrier works | From your carrier, as a separate service | Owners of devices with a cellular module |
| eSIM adapter | Depends on the loaded profile | Wherever the loaded profile works | From the adapter maker | Owners of phones without a built-in eSIM |
What is a carrier eSIM?
A carrier eSIM is your phone number stored on the phone’s chip instead of a plastic card. Calls, texts, your plan and bank codes work exactly as with a regular SIM. Each carrier issues eSIMs under its own rules, and the sign-up process differs from one to the next.
Abroad, a carrier eSIM runs on roaming on the same terms as a plastic SIM: going digital doesn’t make roaming cheaper or switch it off. If you live in or visit Russia, our guide to eSIM from Russian carriers covers how MTS, Beeline, MegaFon, T2 and Yota issue eSIMs and what happens to them on a trip.
What is a travel eSIM?
A travel eSIM is a mobile data plan for your destination country or region that you buy online and install with a QR code. It’s issued by sellers who work with carriers in different countries, and you install it as a second line: your home SIM stays in the phone.
- Most travel plans are data-only, with no local number. On the trip, you call through messaging apps.
- There are single-country plans, regional plans and global plans covering many countries.
- Plans come with a data cap or unlimited — read the fine print on unlimited plans.
- Some sellers offer plans with a phone number, but they’re more the exception than the rule.
The MoreSim catalog covers 200+ destinations. As of October 2026, every MoreSim plan is mobile data only — no phone number, calls or texts, no worldwide plans and no full-speed unlimited (daily plans slow down after the daily allowance) — and the data and validity choices for each country are on its catalog page. The QR code arrives in the chat in about 30 seconds, and the plan starts counting on first connection in the destination.
When do you need a local eSIM?
A local eSIM is a profile from a carrier in the country you’re visiting, with a local number and local rates. It’s useful for long stays or a move abroad, when you need a local number for deliveries, taxis or banks.
Buying a local eSIM as a tourist isn’t always easy. Some carriers sell it online to foreigners, others only in store with a passport, and some require a local address or residence document. SIM and eSIM registration rules differ between countries and change over time, so check the local carrier’s website before your trip.
How does eSIM work in smartwatches and tablets?
An eSIM in a watch or tablet is its own thing, not a copy of your phone’s profile. In a watch with a cellular module, eSIM usually connects as a service from your carrier linked to the same number, while in a tablet it’s a separate data plan.
- Watches: you need a cellular model and a carrier that supports the service. A phone’s travel plan usually can’t be moved to a watch.
- Tablets: if the tablet has eSIM, you can install a travel eSIM for data the same way as on a phone.
- Laptops with a cellular module and routers can also have eSIM, but support for travel profiles depends on the device.
For details on watches, see our article on eSIM in Apple Watch and Galaxy Watch; for tablets, see our guide to eSIM on a tablet.
What is an eSIM adapter, or “physical eSIM”?
An eSIM adapter is a plastic SIM card with a rewritable chip that you load eSIM profiles onto. It goes into the regular SIM slot of a phone without built-in eSIM, and you switch profiles through the adapter maker’s app.
An adapter is a compromise: it takes up a SIM slot, loading profiles requires an app, and not every eSIM profile will work on it. Our separate article on eSIM adapters explains how they work and how to choose one.
Virtual eSIM vs virtual number: don’t mix them up
“Virtual eSIM” is a casual name for a regular eSIM: there’s no plastic, but there is a carrier, a network and a profile on the chip. A virtual number is something else entirely: a number in an app or online service for receiving calls and texts over the internet, and it doesn’t give you a mobile network.
The confusion often comes up with searches like “buy virtual eSIM”. If you need mobile data on a trip, look for a travel eSIM. If you need a number for sign-ups without a SIM card, that’s a virtual number, and it has nothing to do with eSIM.
Which type of eSIM is right for you?
Which type of eSIM you need depends on what you’re after: a number, data or both. For most trips, a two-line setup does the job.
- Check whether your phone supports eSIM: look for an EID after dialing *#06#, or use the compatibility check in the @moresim_bot Telegram bot.
- Decide whether you need your home number on the trip. If you do, keep it on your plastic SIM or carrier eSIM.
- For data on the trip, choose a travel eSIM for a country, a region or a global plan.
- If you’re staying a long time and need a local number, look up the local carrier’s eSIM terms.
- If your phone has no eSIM, consider an adapter or other ways to get connected.
You can buy a MoreSim travel eSIM on the website or in the @moresim_bot Telegram bot, which speaks 40 languages. Pay with Telegram Stars from any country, right in the bot; bank card and SBP payments currently work with cards issued in Russia.

FAQ
What are the different types of eSIM?
By purpose, there are five types of eSIM: your carrier’s eSIM with your number, a travel eSIM for data on a trip, a local eSIM from a carrier in another country, eSIM in watches and tablets, and an eSIM adapter for phones without a built-in eSIM. Technically they’re all the same kind of digital profile; what differs is who issues it and what it gives you.
What is a virtual eSIM?
“Virtual eSIM” is just another name for an eSIM itself: a SIM profile that downloads onto the phone’s chip without a plastic card. It isn’t a virtual number: an eSIM has a carrier and a network, just like a regular SIM. A virtual number for receiving texts in an app is a separate service with nothing to do with eSIM.
How is a local eSIM different from a travel eSIM?
A local eSIM is a profile from a carrier in the country you’re visiting, with a local number and local rates, sold under that country’s rules and often only with a passport. A travel eSIM is bought online before you fly and in most cases gives you data only. A local eSIM suits a long stay where you need a local number; a travel eSIM suits a trip where data is all you need.
What’s the difference between a travel eSIM and a carrier eSIM?
Your carrier’s eSIM is your number in digital form, with calls, texts and your plan, and abroad it works on roaming. A travel eSIM is bought for a trip and in most cases gives you data only in the destination. People usually use them together: your number stays on one line and data runs through the other.
Which eSIM should I choose for travel?
For mobile data on a trip, most people pick a travel eSIM for a country or region: you can buy it online in advance and install it at home. A local eSIM can work for a long stay if the country’s carrier sells it to foreigners. Your home carrier’s roaming is handy when your number matters, but check its terms in advance.
Can one phone hold different types of eSIM?
Yes. A phone stores several eSIM profiles, so your carrier’s eSIM, a travel eSIM and a local eSIM can all sit on it at once. Usually two lines can be active at the same time; the exact number depends on the model.
