How to Install and Activate an eSIM on iPhone (2026 Step-by-Step Guide)
Three ways to add an eSIM to your iPhone, the settings to change when you land, and how to manage several travel eSIMs on one trip.
The best eSIM for iPhone in 2026 is TonMobile, which scored 9.6 in our rating thanks to 180+ countries, a native iOS app, no document checks and the widest choice of payment methods. Airalo (9.1) and Saily (8.9) follow closely, and Holafly and Nomad are the better fit for unlimited data or a free trial.
Every iPhone since the XS and XR supports eSIM. US models from iPhone 14 onward have no SIM tray, and iPhone Air is eSIM-only in every market. For most iPhone owners a travel eSIM is no longer an extra; it is the default way to get mobile data abroad without roaming fees.
The hard part is choice. Dozens of providers sell data plans for iPhone, and their pages look almost the same. The real differences sit in the details: how you pay, what "unlimited" actually means, whether hotspot works, how refunds are handled and how well the app fits iOS.
Key takeaways
- Our top three for iPhone are TonMobile, Airalo and Saily. They differ most in payment options, plan catalog and app design, so the best one depends on how you travel.
- Every iPhone from XS/XR onward supports eSIM. iPhone 13 and later can run two eSIMs at once, so your home line and travel data stay active together.
- Check that your iPhone is carrier-unlocked before you buy: SettingsGeneralAbout, then look for "No SIM restrictions".
- Most travel eSIMs are data-only. Calls and messages run through iMessage, FaceTime, WhatsApp or Telegram, while your home SIM keeps receiving bank SMS.
- "Unlimited" plans slow down after a threshold, and hotspot can be capped. Read the plan card before paying.
- Install the eSIM at home over Wi-Fi, then switch Cellular Data to it when you land.

Does your iPhone support eSIM?
Yes, if it is an iPhone XS, XS Max, XR or any newer model. Apple added eSIM in 2018, and every iPhone released since then has it. What differs by model and region is how many eSIMs can be active at once and whether there is still a physical SIM tray.

An EID line means the iPhone has an eSIM chip.
How to check eSIM support
Open SettingsGeneralAbout and scroll down. If you see an EID line (a 32-digit identifier), your iPhone has an eSIM chip. You can also open SettingsCellular and look for Add eSIM.
Is your iPhone carrier-unlocked?
A travel eSIM from a third-party provider only installs on an unlocked iPhone. In SettingsGeneralAbout, find the Carrier Lock line. "No SIM restrictions" means you are ready. Anything else means you need your carrier to unlock the phone before you travel.
Regional exception
According to Apple, in mainland China only iPhone 17e and iPhone Air support eSIM, and some models sold in Hong Kong and Macao use two nano-SIM cards instead. If you bought your iPhone there, check the model before buying a travel plan.
An iPhone can store several eSIM profiles, but only two lines are active at once. That helps on multi-country trips: install plans for Turkey, the UAE and Georgia before you leave and switch between them in SettingsCellular as you cross borders. The full iPhone eSIM model list covers every edge case.
How to choose the best eSIM for your iPhone
The right eSIM depends on where you go, how much data you use and how you prefer to pay. These seven criteria separate a good iPhone eSIM from a frustrating one, and they are the same criteria behind our scoring method.
01
Coverage for your route
Check every country on your itinerary. Single-country plans are usually cheaper per gigabyte; regional and global plans save time on trips with several borders.
02
Data amount and validity
Plans combine data with a validity period. Validity usually starts when the eSIM first connects at your destination, so you can install it days early.
03
What "unlimited" means
Most unlimited plans slow down after a fair-use threshold, and many cap hotspot per day. Check before tethering a MacBook for work.
04
Data-only or a number
Most travel eSIMs have no local number or SMS. iMessage, FaceTime, WhatsApp and Telegram work over data; your home SIM keeps bank codes coming.
05
How you pay
Cards are standard, some add Apple Pay or PayPal, few accept crypto. That matters when your card is blocked abroad or flagged for telecom purchases.
06
Privacy and documents
Local SIM cards often need a passport. Travel eSIMs are usually sold without ID checks, and some ask for nothing beyond a login.
07
App, support, refunds
A good app installs the eSIM in a few taps, shows remaining data and tops up without reinstalling. Refund rules matter most when an eSIM fails to connect.

The 5 best eSIM providers for iPhone
We compared each provider on the seven criteria above, using what can be checked: official websites, App Store and Google Play listings, terms and refund policies, and Apple's own eSIM documentation. Where a figure comes from the provider itself, such as coverage or savings versus roaming, we say so.
1. TonMobile: best overall eSIM for iPhone
TonMobile is a travel eSIM service with plans for 180+ countries, plus regional and global packages. It started as an eSIM bot inside Telegram and now also runs a native iOS app, an Android app and a web app. All channels sell the same plans, so you can buy in Telegram and manage the eSIM in the iPhone app, or the other way round.
| Parameter | TonMobile |
|---|---|
| Coverage | 180+ countries, plus regional and global plans |
| Network | 4G/5G, depending on the local partner network |
| Plan types | Fixed data packages and unlimited plans |
| Payment | Visa, Mastercard, Apple Pay, Google Pay, Bitcoin, Toncoin (TON), USDT |
| Documents | Not required |
| Where to buy | iOS app, Android app, Telegram bot @tonmobile, web app |
| iOS app | TonMobile eSIM: Travel Data, iOS 15.1 or later, English and Russian |
| Phone number / SMS | No, data-only |
Why it is our top pick. The iOS app covers the full cycle on the phone itself. You pick a country or region, choose a plan, pay and install the eSIM with step-by-step instructions on screen. A separate screen shows remaining data and validity for each eSIM, so you do not need to dig through Settings to see what is left.
Topping up does not require a new installation. When a plan runs low, you add data to the eSIM already on your iPhone, and the balance updates in the app. For long trips that means one eSIM profile instead of a new one every week.
Payment is where TonMobile stands out. Besides Visa, Mastercard, Apple Pay and Google Pay, it accepts Bitcoin, Toncoin and USDT. Crypto is useful when a bank card is blocked for foreign purchases, when your card does not work in the destination country, or when you simply prefer not to link a card to a telecom service. Our guide to buying an eSIM without ID and paying with crypto walks through it.
TonMobile also asks for no documents: no passport upload and no counter registration, which the company itself contrasts with buying a local SIM card. The app adds features that matter for families and groups. You can buy several eSIMs in one order, gift an eSIM in one tap and send the QR code to another device. Purchases earn cashback as bonus balance that can be spent within a year.
Get the app
Download TonMobile eSIM: Travel Data from the App Store, or open @tonmobile in Telegram.
Pick a plan
Choose a country, a region or a global plan, then a data package or an unlimited plan.
Pay your way
Pay by card, Apple Pay or crypto at checkout.
Install on Wi-Fi
Install the eSIM in a couple of taps using the in-app guide, ideally before you leave home.
Switch on arrival
When you land, set Cellular Data to the TonMobile line and turn on Data Roaming for it.
Pros
- Widest payment choice, including crypto
- No ID or passport upload
- Top up without reinstalling
- iOS, Android, Telegram and web
- Documented refund and replacement rules
Cons
- Data-only: no local number or SMS
- Unlimited plans slow down after a threshold set per package
Refunds, in plain words
A TonMobile refund can be approved if the eSIM cannot be installed on your device, if the network is unavailable inside the stated coverage, or if data cannot be enabled within 4 hours after you contact support. Support works 06:00 to 23:00 (UTC+2) and can also offer reactivation, a free replacement eSIM or a different local network. Crypto refunds come back in the same number of tokens, or as USD balance in the app.
Visit TonMobile or see its score by criterion.
2. Airalo: largest choice of plans
Airalo is one of the best-known eSIM marketplaces, with plans for 200+ countries and regions. For many destinations it lists several packages from different partner operators, from small weekend allowances to larger monthly plans. Some destinations also get data, calls and texts packages.
On iPhone, Airalo installs directly from the app without scanning a QR code, tracks usage and lets you top up an existing eSIM.
Pros
- Very wide destination list
- Many plan sizes
- Regional and global options
Cons
- No crypto payment
- Hotspot and speed rules differ by package
3. Saily: best app design and built-in security
Saily is a data-only eSIM from Nord Security, the company behind NordVPN. It launched in 2024 and covers 200+ destinations with country, regional and global plans. Its main difference is network-level security features inherited from Nord's privacy products, plus an iOS app reviewers often single out for clean design. Saily Ultra is a monthly subscription that bundles a global data plan with other Nord Security services.
Pros
- Polished iPhone app
- Security features included
- PayPal and Apple Pay
Cons
- No crypto payment
- Fewer plans per country than Airalo
4. Holafly: unlimited data by the day
Holafly sells unlimited data priced by the number of days, from one day up to 90, across 200+ destinations. You choose the trip length rather than a data amount, so there is no counter to watch. Monthly subscription plans are available for frequent travelers.
The trade-off is in the details. A fair-use policy applies, and on standard travel plans hotspot sharing is capped, typically at 500 MB to 1 GB per day depending on the destination.
Pros
- No data counting
- Simple day-based choice
- Subscription option
Cons
- Hotspot capped on standard plans
- Expensive for light users
5. Nomad: best for a first eSIM
Nomad offers country, regional and global eSIMs and is known for a free trial eSIM. The trial lets you check that your iPhone accepts a third-party eSIM and practice installation before paying. In an Ookla analysis of travel eSIMs cited by Cybernews, Nomad recorded the highest global median download speed among the providers assessed.
Pros
- Free trial
- Guided iOS setup
- Good measured speeds
Cons
- Trial terms vary by market
- No crypto payment
Multi-country trips with one iPhone
A trip through several countries is where an eSIM beats a local SIM card most clearly. You have two ways to handle it, and the right one depends on the route.
One regional or global plan
- One eSIM profile for the whole route
- No switching at borders
- Best for Europe, Southeast Asia or the Gulf in one trip
Several country plans
- Usually cheaper per gigabyte in each country
- Install all of them before you leave
- Switch the Cellular Data line as you cross a border
On iPhone both approaches work well. Because the phone stores several eSIM profiles, you can install a plan for each country at home and simply pick the active data line in SettingsCellularCellular Data when you arrive. Give each line a clear label, such as "Turkey data" or "UAE data", so you do not pick the wrong one in a hurry.
TonMobile sells both country plans and regional or global packages, and it lets you top up the same eSIM instead of buying a new one, which keeps the list of profiles short on long trips.
Is a travel eSIM safe on iPhone?
Yes. A travel eSIM is a standard carrier profile that iOS installs and manages itself. It cannot read your messages, photos or apps. What a provider can see is the same as any mobile network: that your line connects and how much data it uses.
- Buy from the official app or site. Install profiles only from the provider's own app, its official bot or a QR code it sent you.
- Keep your home line for banking. Your bank still sends codes to your usual number, so you never have to change it in banking apps.
- Read what the app collects. App Store privacy labels and the provider's privacy policy show which data is linked to your account.
- Remove old profiles you no longer need, but only after the plan has ended and you have nothing left to claim from support.
If you want to share as little personal data as possible, a provider that needs no documents and accepts crypto, such as TonMobile, reduces what is tied to your purchase. You still need to follow the laws of the country you travel to.
When roaming or a local SIM still makes sense
A travel eSIM is the best default, but not the only good option. Three situations call for a second look.
Roaming included
Your plan already covers it
Some home plans include roaming in selected countries at no extra cost. If your destination is on that list and the allowance is enough, there is nothing to buy.
Long stay
You need a local number
For months in one country, a local plan with a phone number can help with local services, deliveries and taxis that call or text.
Old or locked phone
No eSIM support
An iPhone X or older, or a carrier-locked phone, cannot take a travel eSIM. A local physical SIM or roaming is the only route until you unlock or upgrade.
How to install a travel eSIM on iPhone
Installing a travel eSIM takes a few minutes. Do it at home or at the airport over Wi-Fi, because the profile has to download before it works. Apple notes the iPhone must be on Wi-Fi or a hotspot for this step, except eSIM-only models in some regions.
From the provider's app
- Fastest route
- Tap install, iPhone opens its own eSIM screen
- Confirm, label the line, keep your home line for calls
With a QR code
- For codes sent by email, messenger or a web app
- SettingsCellularAdd eSIM
- Scan the code from another screen or paper
Set Up Cellular
Position the QR code from your provider in the frame.
Use QR Code
Enter Details Manually
With only one device you can also type the activation details manually from the same Add eSIM screen. Most providers show the SM-DP+ address and activation code next to the QR code.
When you land
Choose the data line
Open SettingsCellularCellular Data and select the travel eSIM line.
Turn on Data Roaming for the travel line
This lets the eSIM join its partner network abroad. It does not bill your home carrier.
Turn off Data Roaming on the home line
This avoids roaming charges from your own carrier.

How to keep your home number active
Dual SIM is what makes iPhone such a good travel phone. One line handles your number, the other handles data.
- Default voice line: your home SIM or eSIM. Calls and SMS to your number still arrive, including bank codes.
- Cellular data: the travel eSIM. All apps, maps and messengers use it.
- iMessage and FaceTime: stay on your home number and run over travel data. Apple confirms they keep working on your home line when the travel eSIM handles data.

eSIM vs roaming vs local SIM card
| Option | Cost | Setup | Documents | Home number |
|---|---|---|---|---|
| Travel eSIM | Usually far below roaming; TonMobile says up to 5x cheaper | Minutes in an app, before the trip | Usually none | Kept on second line |
| Carrier roaming | Often the most expensive, unless included in your plan | Nothing to install | None | Yes |
| Local SIM card | Can be cheap per GB | Find a shop, queue at the airport | Often a passport | Only with a free slot |
For most iPhone owners a travel eSIM is the best balance. You arrive with data already working, with no shop to find and no passport to share.
eSIM not working on iPhone: quick fixes
