eSIM vs physical SIM card: a side-by-side comparison

Side-by-side comparison table

What is an eSIM?

An eSIM (embedded SIM) is a chip soldered into your phone at the factory. It works exactly like a traditional SIM card but does not need a physical slot. You download a carrier profile onto the chip by scanning a QR code or tapping a link. The phone activates the plan within minutes.

Modern iPhones (XR and newer), Google Pixels (3 and newer), and Samsung Galaxy phones (S20 and newer) all support eSIM. The iPhone 14 US model and later have no physical SIM slot at all. Apple went eSIM-only.

When a physical SIM still wins

Physical SIMs work in older phones that do not support eSIM. If your phone was made before 2018, it likely has no eSIM capability. Physical SIMs are also available at airport kiosks and convenience stores in most countries, which helps travelers who did not plan ahead.

In a few countries, local physical SIMs come with a local phone number for receiving calls from local contacts. Travel eSIMs are data-only, so they do not provide a local number.

When an eSIM is the better choice

If your phone supports eSIM, the setup is faster and cheaper. You buy it before your flight, install it at home on WiFi, and land with data already working. No language barriers at a shop, no risk of getting an incompatible SIM size, and no losing the tiny plastic card. See what carrier roaming costs without an eSIM.

• You can store multiple eSIMs for different countries on one phone
• Your home carrier SIM stays active for calls and texts
• No physical card to lose, damage, or have stolen
• Install from anywhere. No shop visit required

Dual SIM setup: running physical SIM and eSIM together

Most travelers use a dual SIM setup: their carrier on the physical SIM (or primary eSIM), and a travel eSIM for data. This gives you the best of both. Your home number stays active for calls and texts while the travel eSIM handles all data traffic at local rates.

Here is how to configure dual SIM on each platform:

• iPhone: Go to Settings > Cellular > Cellular Data. Select the travel eSIM as the data line. Your carrier SIM stays default for calls and texts
• Samsung Galaxy: Go to Settings > Connections > SIM manager. Set the travel eSIM as the mobile data SIM. Your physical SIM handles voice
• Google Pixel: Go to Settings > Network & internet > SIMs. Tap the travel eSIM and toggle Mobile data on. Set your carrier SIM for calls

One important step: turn off data roaming on your carrier SIM after setting up dual SIM. If you skip this, your carrier may still route some data through its roaming connection and charge you. See the step-by-step guide to disabling roaming.

Prepaid SIM vs eSIM for travel: a cost and convenience comparison

A prepaid physical SIM card from a local shop and a travel eSIM both give you local data at local rates. The difference is convenience, time, and total cost.

A local prepaid SIM can cost less than a travel eSIM. The eSIM wins on buying before you land and on keeping your home number active. The Italy prices in the cost section below show both sides for one trip.

eSIM security: why carriers and banks prefer eSIM

Physical SIM cards are the weakest link in phone security. SIM-swap attacks, where a criminal convinces your carrier to transfer your number to a new SIM, are a known fraud against physical SIM cards. Once a criminal has your number, they can bypass SMS-based two-factor authentication and access your bank accounts, email, and crypto wallets.

An eSIM is harder to steal. It is soldered into the phone and protected by the device's passcode and biometric lock. A criminal cannot walk into a carrier store and request a new eSIM without your phone.

For travelers, the physical security matters too. A pickpocket who steals your physical SIM can insert it in another phone and intercept your calls and texts. An eSIM remains locked inside your device.

eSIM-only phones leave the eSIM as the travel option

Apple removed the physical SIM tray from US-sold iPhones starting with the iPhone 14 in September 2022. All iPhone 14, 15, and 16 models sold in the United States are eSIM-only. Google followed with the Pixel 9 in 2024, also eSIM-only in the US market.

For travelers with eSIM-only phones, the choice is already made. You cannot buy a local physical SIM at an airport kiosk. A travel eSIM is the only option for mobile data abroad (besides carrier roaming). The good news: eSIM-only phones support multiple stored eSIM profiles. An iPhone 15 stores up to 8 eSIM profiles at once, with 2 active simultaneously.

If you plan to travel with an eSIM-only phone, install your travel eSIM at home on WiFi before you fly. You cannot install an eSIM without an internet connection, and airport WiFi is often slow or requires a sign-up.

Italy for 7 days: day pass, eSIM and local SIM priced

One trip, three prices. For 7 days in Italy, AT&T's $12 day pass costs $84, the cheapest 20 GB Italy eSIM in this site's price file costs $25.49, and the gap is $58.

The physical SIM is the third price. An Italian airport SIM costs $10-25 for 20-50GB / 30 days. A local prepaid SIM in town costs $8-20 for 20-100GB / 30 days. At the low end, a local SIM costs less than the eSIM. The eSIM wins on the day-pass gap, on buying before you land, and on keeping your home number active, since a physical SIM swap takes your home line offline.

HelloRoam, an eSIM platform, lists Iliad, TIM and Wind as its Italy networks. HelloRoam refunds an unactivated eSIM for 180 days.

How to get started with an eSIM

1. Confirm your phone supports eSIM (Settings > Cellular on iPhone).
2. Pick an eSIM provider based on your destination and data needs.
3. Purchase a plan and receive a QR code via email.
4. Scan the QR code in your phone's settings to install.
5. Activate the eSIM when you arrive, or set it to activate automatically.

Frequently asked questions

Can I use eSIM and physical SIM at the same time?

Yes. Most modern phones support dual SIM — one physical and one eSIM running simultaneously. Keep your home number on the physical SIM and add a travel eSIM for cheap data abroad.

Is eSIM more secure than a physical SIM?

Yes. An eSIM cannot be physically stolen or swapped without your phone's passcode. This protects against SIM-swap attacks that target physical cards. Saily adds an extra layer with built-in VPN from the NordVPN team.

Which phones support eSIM?

iPhone XR and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and most flagship Android phones from 2020 onward. The iPhone 14 in the US is eSIM-only with no physical SIM slot.

Can I transfer an eSIM to a new phone?

Each travel eSIM provider sets its own rule for moving an eSIM to a new phone. Ask the provider before you switch phones mid-trip, and install the travel eSIM on the phone you will carry.
