eSIM QR Code: How to Get, Scan, and Fix Yours

Your eSIM QR code comes from your mobile carrier — Verizon, AT&T, T-Mobile, or whoever you pay each month — and it's tied to your specific line. This guide shows how to get that code, scan it on an iPhone or Android, and fix it when it won't activate. Nothing to download, nothing to sign up for.

The basics

What Is an eSIM QR Code?

An eSIM is a SIM card built right into your phone. Instead of popping in a physical chip, your carrier sends you a digital SIM profile — and the eSIM QR code is how that profile lands on your device.

Here's what the code actually holds: an address for your carrier's activation server (the technical name is SM-DP+) plus a one-time activation code. When you scan it, your phone reads those two things, connects to the carrier, and downloads the profile for that line. The code is really just a pointer that says “go here, use this key, set up this number.”

Two things matter most. First, the code comes from your carrier and is tied to your account — so a third-party QR code generator can't make a working one, and neither can we (more on that at the bottom). Second, it's essentially single-use: once the eSIM installs, that same code usually won't work again. If you lose it or it gets used up, your carrier simply issues a fresh one.

Verizon

How to Get Your Verizon eSIM QR Code

If you're on Verizon, there are four reliable ways to get your eSIM QR code. All of them pull the code that's tied to your line — pick whichever is easiest for you.

My Verizon app

Open the app and follow the prompts for your device. Usually the fastest route, since it already knows your account and line.

My Verizon website

Sign in and head to the Bring Your Own Device (BYOD) page or the Add a Line page. Both walk you through eSIM setup and hand you the code.

A Verizon store

Stop by a Verizon retail store and a rep can pull up your QR code and help you activate on the spot.

Call Verizon

Dial 800-922-0204 (8AM–7PM Mon–Sat, 8AM–5PM Sun) and support can get your code sorted over the phone.

Lost or already used it? Because the code is single-use, one you already scanned — or canceled halfway through — usually won't work again. Contact Verizon through the app or the support line and they'll re-provision your eSIM and send a fresh code tied to your profile.

Verizon lists eSIM support on iPhone X, 11, 12 and newer, Google Pixel, Motorola, Samsung phones and tablets, and some Windows laptops. Want the official steps? See Verizon's eSIM activation instructions. One tip: you can't scan a code with the same phone that's displaying it, so pull it up on a computer or second screen and scan from there.

T-Mobile

How to Get Your T-Mobile eSIM QR Code

T-Mobile builds most of eSIM setup right into its app, so you often won't need to handle a QR code at all. Here's how to get yours.

  • In the T-Life app: connect to the T-Mobile network first, then go to the Manage tab, choose your line, tap “SIM transfer or activation,” and hit “Get Started.” The app handles the profile for you.
  • From your T-Mobile account: sign in on the app or website, go to your line or device, and look for “Switch to eSIM” or “Get eSIM.”

If your device specifically asks you for a QR code rather than setting things up automatically, contact T-Mobile — they can email the QR code straight to you. For the official walkthrough, see T-Mobile's SIM and eSIM support page.

AT&T

How to Get Your AT&T eSIM QR Code

On AT&T, you get your eSIM QR code through the app or the website, and support can step in if the eSIM isn't cooperating.

  • myAT&T app or att.com/esim: open the myAT&T app or go to att.com/esim to reach the eSIM activation section. AT&T generates your QR code and either emails it to you or shows it right on the activation page.
  • Call AT&T support: dial 800.331.0500 if you hit a wall. They can check that your device is eligible, reset the eSIM profile, or provision the eSIM manually when it isn't showing up.

For the official rundown, see AT&T's eSIM guide.

Prepaid, an MVNO, or travel? Metro by T-Mobile, Mint Mobile, Visible, US Mobile, Google Fi, and travel eSIM apps like Airalo all work the same way: you get the QR code from that provider's app, website, or a confirmation email. Once you have it, the steps below for scanning and troubleshooting apply no matter who your provider is.

Scan it

How to Scan an eSIM QR Code on iPhone & Android

Once you've got your code, adding it takes about a minute. Menus move around a little depending on your phone and its software version, so if a label doesn't match exactly, look for the closest wording. Get on Wi-Fi first — your phone downloads the profile over the internet.

On iPhone

  1. 1Open Settings, then tap Cellular (it may say Mobile Data or Mobile Service in some regions).
  2. 2Tap Add eSIM or Add Cellular Plan.
  3. 3Choose Use QR Code.
  4. 4Point the camera at the code and follow the on-screen steps.

On Android

  1. 1Open Settings, then Network & internet (it's Connections on Samsung).
  2. 2Tap SIMs or Mobile network — on Samsung, go to SIM manager.
  3. 3Tap Add, +, or Download a SIM instead? (on Samsung, Add eSIM).
  4. 4Scan the QR code and follow the prompts.

Manual entry (no scanning). Every Add eSIM screen has an option like “Enter Details Manually” (iPhone) or “Enter Code Manually” (Android). Type in the SM-DP+ address and activation code — the exact information the QR code holds — which saves you when a code won't scan or you only got the details as text.

iPhone eSIM Quick Transfer. Upgrading from one iPhone to another? Newer iPhones can move an eSIM straight over from your old iPhone via Bluetooth — no QR code needed. Apple calls this eSIM Quick Transfer, and it's often the simplest path when both phones are nearby.

Troubleshooting

eSIM QR Code Not Working? How to Fix It

If your eSIM QR code won't scan or won't activate, it's almost always one of a handful of things. Work down this list in order and you'll usually be up and running fast.

It's already been used

The code is single-use, and even canceling partway through setup can burn it. Have your carrier re-issue a fresh one.

No internet connection

Your phone downloads the profile over Wi-Fi or data, even though the QR itself is local. Get on stable Wi-Fi and try again.

Your phone is carrier-locked

A phone locked to another carrier won't accept the new eSIM. It has to be unlocked first.

Your device isn't supported

Confirm your model actually supports eSIM and appears on your carrier's compatible list.

Camera or scan trouble

Clean the lens, add light, and raise screen brightness if you're scanning off another screen. Or skip it and use manual entry.

Wrong date and time

Set your phone's date and time to automatic, then retry.

Give it a restart

Power the phone off and back on, then try the code again.

Outdated software

Update to the latest iOS or Android and scan once more.

Still stuck?

Enter the details manually, or contact your carrier for a brand-new code tied to your line.

One quick note on who we are

QRKIT is a free QR code generator for things like links, Wi-Fi networks, business cards, and payments. eSIM activation codes aren't in that group — those come from your carrier, tied to your account, and only your carrier can issue them. If you need a real QR code for a link or your Wi-Fi, you can make one free in a couple of taps.
