Is the Samsung S23 Plus eSIM compatible?

Yes, the Samsung Galaxy S23 Plus is eSIM compatible. All regional variants of the device support eSIM, and you can run dual SIM by pairing a physical nano-SIM with an eSIM, or by activating two eSIMs at the same time. The phone can store multiple eSIM profiles but only two lines—physical or eSIM—can be active simultaneously.

How to activate eSIM on Samsung S23 Plus?

Open Settings, tap Connections, then SIM manager, and select Add eSIM. Scan the QR code provided by your carrier, wait for the profile to download (about 60 seconds), and label the line. You can also enter an activation code manually if you don't have a QR code. Once installed, choose which line handles calls, texts, and data in SIM manager.

Does Samsung S23 have eSIM or physical SIM?

The Samsung Galaxy S23 series—including the S23, S23 Plus, and S23 Ultra—supports both eSIM and a physical nano-SIM. Each model has one nano-SIM slot and built-in eSIM capability, so you can use a physical SIM alone, an eSIM alone, or both together for dual SIM functionality. You can also activate two eSIMs if you prefer to go card-free.

How many eSIMs can S23 have?

The Samsung Galaxy S23 Plus can store multiple eSIM profiles (typically five or more), but only two SIM connections—physical or eSIM—can be active at once. For example, you might keep a home eSIM, a work eSIM, and a travel eSIM saved on the device, then switch between them in SIM manager depending on which two lines you need active at any given time.

Can I use dual eSIM on the Samsung Galaxy S23 Plus?

Yes, the Samsung Galaxy S23 Plus supports dual eSIM mode. You can activate two eSIMs simultaneously without inserting a physical SIM card, which is useful if you want a fully digital setup or travel frequently and prefer managing multiple carriers through software. Switch between saved eSIM profiles in Settings > Connections > SIM manager whenever you need a different combination of lines.

Does the Samsung Galaxy S23 Plus support eSIM?

Samsung Galaxy S23 Plus eSIM compatibility

Yes, the Samsung Galaxy S23 Plus supports eSIM. All variants of the device—regardless of region—include eSIM functionality built in. You can use the Samsung Galaxy S23 Plus with a dual SIM configuration: one physical nano-SIM in the tray plus one eSIM, or two eSIMs simultaneously if you prefer to go entirely SIM-card-free.

The phone supports multiple eSIM profiles stored on the device (up to five or more, depending on your carrier and software version), though you can only have two active lines at once—either one physical SIM and one eSIM, or two eSIMs. This flexibility makes the Samsung Galaxy S23 Plus ideal for separating work and personal numbers, or pairing your home carrier with a travel eSIM when you're abroad.

Dual SIM on the Samsung Galaxy S23 Plus

The Samsung Galaxy S23 Plus includes a single nano-SIM card slot on the side of the device. Unlike some older Samsung models that offered dual physical SIM trays in certain markets, the S23 Plus relies on eSIM for its second line. If you want two active numbers, you'll insert a physical nano-SIM and activate an eSIM, or activate two eSIMs and leave the SIM slot empty.

How to set up an eSIM on the Samsung Galaxy S23 Plus

Set up an eSIM in Settings

Installing an eSIM on your Samsung Galaxy S23 Plus takes about a minute once you have your QR code or activation details from your carrier. You'll need a Wi-Fi or mobile data connection to complete the download. Here's the step-by-step process:

Open Settings and tap Connections.
Tap SIM manager (or SIM card manager, depending on your software version).
Tap Add eSIM or Add mobile plan.
Choose Scan carrier QR code. Hold your phone steady over the QR code provided by your carrier or eSIM provider.
The Samsung Galaxy S23 Plus will download the eSIM profile. This usually takes 30–60 seconds.
Once installed, tap Done and give your eSIM line a label—like "Travel" or "Work"—so you can identify it easily.
In SIM manager, set your preferred line for calls, texts, and mobile data. You can switch these defaults anytime.

If your carrier provides an activation code (SM-DP+ address and activation code string) instead of a QR code, tap Enter activation code manually in step 4 and paste the details.

Activate eSIM on Samsung S23 Plus before you travel

You can install an eSIM profile while you're still at home—even before your trip. The line won't start billing or consume data until you activate it and enable mobile data for that profile. This means you can set everything up on Wi-Fi, test that the eSIM appears in SIM manager, and be ready to go the moment you land.

Using a travel eSIM on the Samsung Galaxy S23 Plus

Stay connected abroad without roaming fees

A travel eSIM is the simplest way to get mobile data when you're overseas. Instead of paying international roaming charges on your home carrier or hunting for a local SIM card at the airport, you install a data-only eSIM before you leave. When you arrive, turn on the eSIM line in SIM manager, enable data roaming for that profile, and you're online.

Because the Samsung Galaxy S23 Plus supports dual SIM, your home number stays active for calls and text messages (including two-factor authentication codes), while the travel eSIM handles all your data—maps, messaging apps, email, and web browsing. You control which line is used for data in Settings > Connections > SIM manager > Mobile data.

Travel eSIMs typically cover single countries or entire regions, with validity periods from a few days to a month. You can browse eSIM plans by destination, compare data allowances, and install the QR code in under a minute. No need to swap physical SIM cards or worry about losing the tiny tray ejector tool.

Tips & troubleshooting

Turn on data roaming for your eSIM line

Even though you've installed a local or regional travel eSIM, you still need to enable data roaming for that line. Go to Settings > Connections > Mobile networks, select your eSIM, and toggle Data roaming on. This sounds counterintuitive—roaming usually means extra fees—but for an eSIM that's already local to the country you're visiting, roaming is simply how the phone connects to the network. You won't be charged roaming rates by your home carrier because you're using a different profile.

Keep your home SIM active for calls and 2FA

Leave your physical home SIM (or home eSIM) turned on for voice calls and SMS, especially if you rely on text-message two-factor authentication for banking or work apps. In SIM manager, set your home line as the default for Calls and Messages, and set your travel eSIM as the default for Mobile data. This way you stay reachable on your regular number while your data traffic runs over the cheaper local eSIM.

Fix an eSIM that won't activate

If the QR code won't scan, make sure your screen brightness is turned up and there's no glare on the printed or displayed code. You can also ask your eSIM provider for the manual activation code (SM-DP+ address and activation code) and enter it by hand in Settings > Connections > SIM manager > Add eSIM > Enter activation code manually.

If the eSIM profile downloads but won't connect to the network, restart your Samsung Galaxy S23 Plus, then double-check that mobile data and data roaming are both enabled for the eSIM line. Some carriers require you to activate the eSIM within a specific time window or geographic region, so confirm the activation terms in your provider's email or app.

For general troubleshooting across different devices and carriers, you can find additional eSIM setup help or check another device's eSIM compatibility if you're considering a second phone or tablet.
