eSIM has been mainstream since 2018 and most phones sold today support it. But a lot of people still default to a physical SIM at the airport out of habit or because the information online is confusing. Here is a plain comparison based on what actually matters for a FIFA World Cup 2026 trip.
Side by Side Comparison
| Factor | eSIM | Physical SIM |
|---|---|---|
| Where you buy it | Online before departure | Airport kiosk or local store after arrival |
| Time to get connected | Instant: scan QR code, activate | 15 to 60 min including travel to store |
| Multi-country coverage | One plan for all 3 host nations | Usually one SIM per country |
| Keep your home number | Yes, home SIM stays in your phone | No, you remove the home SIM |
| Local phone number | Data-only (no local number) | Yes, includes local number |
| Security | Cannot be physically stolen | Can be removed or lost |
| Phone requirement | Must be eSIM-compatible and unlocked | Works in any unlocked phone |
| Long single-country stay (14+ days) | Comparable cost | Often slightly cheaper locally |
Which Phones Support eSIM
iPhone
- eSIM works on iPhone XR and iPhone XS (2018) and all models since
- iPhone 14 and later sold in the USA have no physical SIM tray at all. They are eSIM-only. International iPhone 14+ models keep a physical SIM slot.
- iPhones sold in mainland China do not support eSIM on any model
- To check: Settings > General > About > Available SIM. If you see "Add eSIM" you are good.
Samsung Galaxy
- eSIM works on Galaxy S20 (2020) and all S-series, Z Flip, Z Fold, and Note 20 models since
- Some US carrier-branded Samsung models ship with eSIM disabled. Unlocked models bought directly from Samsung have it enabled.
- Samsung models sold in China, Hong Kong, and Taiwan generally do not support eSIM even if the model number is the same elsewhere
Google Pixel
- eSIM works on Pixel 3 (2018) and all models since
- Pixel 7 and later support dual eSIM, meaning two eSIM profiles can be active simultaneously with no physical SIM needed at all
The Case for eSIM on a FIFA World Cup Trip
The FIFA tournament is a specific travel scenario where eSIM's advantages stack up clearly:
- You land in a new country with no local connectivity. An eSIM is already installed and activates automatically when you leave the plane. You are on a local network before you reach baggage claim. With a physical SIM, you are hunting for a kiosk or a carrier store.
- Your trip may cross three countries. A North America regional plan covers the USA, Mexico, and Canada on one eSIM. With physical SIMs, you are buying three separate plans and swapping cards at each border.
- Your home number matters. Banking 2FA codes, employer calls, family messages: your home SIM stays active in your phone while the eSIM handles your travel data. Nothing goes offline.
- Digital tickets need data before the gate. If your FIFA ticket app fails to load at the stadium entrance, you need a working data connection immediately. An installed eSIM removes that risk.
When a Physical SIM Still Makes Sense
eSIM is not right for every situation:
- Your phone does not support eSIM (pre-2018 models or certain regional variants)
- Your phone is carrier-locked and you have not unlocked it yet
- You need a local phone number for taxi apps or restaurant bookings in Mexico
- You are staying in one country for more than 3 weeks; local prepaid SIMs in Mexico and Canada can be marginally cheaper for extended stays
Carrier Lock: The Thing That Trips People Up
If you bought your phone on an installment plan from Verizon, AT&T, or T-Mobile, it may be carrier-locked. A locked phone will not work with another carrier's eSIM or SIM card.
- T-Mobile typically unlocks after 40 days of active service
- AT&T typically unlocks after 60 days
- Verizon unlocks after the device is paid in full
To unlock: contact your carrier with your IMEI number (dial *#06# on any phone) and request an unlock. It takes a few hours to 2 days. Do this before your trip.
Canadian phones are different: federal regulations since December 2017 require all phones sold in Canada to be sold unlocked. If you have a Canadian phone, there is nothing to check.
Four Myths About eSIM
eSIM is data-only and cannot make phone calls.
A carrier-issued eSIM (from Verizon, Telcel, Rogers, etc.) supports full voice calls and SMS. Travel eSIMs from third-party retailers like eSpeedz are data-only by design and price, not by technical limitation. You keep voice calls on your home SIM.
You can only store one eSIM at a time.
Most modern phones can store 8 to 15 eSIM profiles. iPhone 15 and later can store up to 8. The limit is on how many can be active simultaneously (typically 2), not how many are stored. You can keep your home carrier eSIM and your travel eSIM on the phone at the same time.
eSIM is always more expensive than buying a local SIM.
For a single-country stay of 14+ days, local SIMs can be slightly cheaper. But for multi-country trips or stays under two weeks, an eSIM regional plan is usually comparable in cost and saves you the time and hassle of finding a carrier store.
Removing your home SIM card is the only way to use a travel eSIM.
On any dual-SIM phone with eSIM support (which includes virtually all phones from 2018 onwards), your home SIM and your travel eSIM run simultaneously. You do not touch the physical SIM card at all.
USA, Mexico, Canada, North America (all 3 countries), or Global (120+ countries). Plans from $9.99. Scan the QR code when you land and you are connected.
