Galaxy Z Flip3 eSIM: Check Compatibility & Set It Up

Yes, the Samsung Galaxy Z Flip3 supports eSIM, and you can check compatibility and set it up in about five minutes. This guide walks you through checking if your specific model and carrier support eSIM, then shows you exactly how to activate it on your phone.

What Is eSIM and Why Use It on the Z Flip3

An eSIM (embedded SIM) is a digital SIM card built into your phone. Instead of inserting a physical nano-SIM, you download a carrier profile over Wi-Fi or mobile data. On the Z Flip3, this means you can have two active phone numbers—one on the physical SIM and one on the eSIM—without opening the SIM tray. Benefits include easier switching between carriers for travel, using a local data plan while abroad, and freeing up the SIM slot for a second number.

Check if Your Z Flip3 Model Supports eSIM

Not every Z Flip3 variant has eSIM enabled. The feature depends on the model number and the region it was sold in. To check your model, go to Settings > About Phone > Status and look at the model number. The following models are generally eSIM-capable:

• SM-F711B (international, most regions)
• SM-F711U (US, carrier-unlocked and most carrier versions)
• SM-F711U1 (US, factory-unlocked)
• SM-F711W (Canada)

If your model is SM-F7110 (China, Hong Kong) or a carrier-locked US model from a carrier that doesn’t support eSIM, it may not have the option. The simplest way to confirm: open Settings > Connections > SIM Card Manager. If you see “Add eSIMâ€� or “Add mobile plan,â€� your phone supports it. If not, your model or carrier has disabled it.

Carrier Compatibility and eSIM Activation Methods

Even if your phone supports eSIM, your carrier must offer eSIM activation for the Z Flip3. Most major US carriers (AT&T, T-Mobile, Verizon) support it, as do many international carriers. There are two common ways to activate:

1. QR code from carrier: Your carrier emails you a QR code or provides it in their app. You scan it with your phone’s camera.
2. Carrier app or website: Some carriers let you download the eSIM profile directly through their app, which then sends the profile to your phone.

If you’re not sure your carrier supports eSIM for the Z Flip3, check their website or contact customer support. You can also try the “Add eSIM� option in Settings—if your carrier doesn’t support it, you’ll get an error.

Step-by-Step: How to Set Up eSIM on Your Z Flip3

Once you’ve confirmed compatibility and have the QR code or activation info from your carrier, follow these steps:

1. Go to Settings > Connections > SIM Card Manager.
2. Tap Add eSIM (or “Add mobile plan�).
3. Choose Scan QR code from the carrier or Enter activation code if you have one.
4. Scan the QR code using the camera, or type in the code manually.
5. Wait for the profile to download. This usually takes under a minute.
6. Once downloaded, you’ll see it listed under “eSIM plans.� Tap it to set it as your default for data, calls, or both.
7. If you want to use both SIMs, assign which SIM is for calls, texts, and data. You can also enable “Dual SIM always on� to receive calls on both.

If you don’t have a QR code, some carriers allow you to tap “Add eSIM� and then “Download a SIM from your carrier instead�—this opens a carrier page where you log in and activate.

Common Problems and How to Fix Them

Users often hit a few snags during setup. Here are the most frequent issues and their fixes:

• “No eSIM option in Settingsâ€�: Your model may be region-locked or carrier-locked. Try inserting a physical SIM from a supported carrier, then check again. If still missing, your carrier may not have enabled eSIM for your account.
• QR code won’t scan: Clean the camera lens, ensure good lighting, and hold the phone steady. If it fails, ask your carrier for a manual activation code (a long string of numbers).
• “Network not availableâ€� after activation: Restart your phone. If that doesn’t work, go to Settings > Connections > Mobile Networks > Network Operators and select your carrier manually.
• eSIM profile disappeared: Go to SIM Card Manager, tap the eSIM, and choose “Activate.â€� If it’s gone entirely, contact your carrier to re-send the profile.
• Data not working on eSIM while physical SIM is active: In SIM Card Manager, tap “Mobile dataâ€� and select the eSIM. Also check that your data plan is active.

How to Switch Between Physical SIM and eSIM

After setup, you can switch which SIM is used for calls, texts, and data at any time. Go to Settings > Connections > SIM Card Manager. Under “Preferred SIM for,� tap each category (voice, text, data) and choose the SIM you want. You can also set “Dual SIM always on� to keep both active. To temporarily disable the eSIM, toggle it off—you won’t lose the profile, just turn it off.

Frequently Asked Questions

Does the Z Flip3 have a physical SIM slot too?

Yes, the Z Flip3 has a single nano-SIM slot. You can use one physical SIM and one eSIM simultaneously, giving you two active numbers.

Can I use eSIM on a carrier-locked Z Flip3?

It depends on the carrier. Some carriers allow eSIM on locked phones, others don’t. Check with your carrier. If the phone is locked to a carrier that supports eSIM, it usually works.

How do I remove an eSIM profile?

Go to Settings > Connections > SIM Card Manager, tap the eSIM, and choose “Remove.� This deletes the profile from your phone. You can re-add it later with the same QR code or by contacting your carrier.

Will eSIM work while traveling internationally?

Yes, if your carrier supports international roaming or you add a local eSIM data plan. Many travel eSIM providers offer plans that work on the Z Flip3. Just add the new eSIM profile and select it for data.

Can I have two eSIMs on the Z Flip3?

No, the Z Flip3 supports only one eSIM profile at a time, plus one physical SIM. You can have multiple profiles stored, but only one eSIM can be active at a time.

Does eSIM drain the battery faster?

No, eSIM uses the same modem as a physical SIM and has no noticeable impact on battery life. If you have both SIMs active, you may see slightly higher battery usage due to maintaining two connections.
