Where Does an eSIM QR Code Come From?

Only the company selling you the plan can issue an eSIM QR code. It is generated against your specific order, delivered by email or in their app, and it is not something you can create, find in a settings menu, or obtain from anywhere else.

For a travel plan that means the provider you bought from; for your own number it means your carrier. Both normally issue within minutes of payment clearing.

Delivery varies by provider, and knowing which of these to expect saves a lot of inbox searching:

• An email with the code as an image, usually within a few minutes of purchase.
• A code inside the provider’s own app, under an orders or my-eSIMs section. Increasingly the default, and often the only place it lives.
• The SM-DP+ address and activation code as text, with no image at all. Those two carry everything a phone needs, and they are the fields the GSMA’s SGP.22 specification actually requires, so a text version installs exactly the same way.
• A plain link rather than a code, which iOS 17.4 and later opens straight into the install sheet.
• Nothing to scan, because the purchase installs the profile directly from the app. Increasingly common and perfectly normal — Apple supports installing from a carrier or provider app as a first-class route alongside the camera.

Before contacting anybody, three checks account for most missing codes:

1. 1Look in spam and in promotions or updates tabs. Order emails with an embedded image land there routinely.
2. 2Check the address you actually used at checkout, especially if you paid through a wallet that supplies a relay address.
3. 3Open the provider’s app and look under orders. Many issue there first and email second, or not at all.

If none of those turns it up, the likely cause is a payment held for review rather than a lost email. Support can confirm in a message, and reissue if needed. What counts as a normal wait is worth knowing before you chase it.

Converting an existing line to eSIM is a carrier operation, not something the phone can do alone. Google says the same in its Pixel instructions: if you did not buy the phone from your carrier, contact them to check they support eSIM at all. Most large carriers now offer it free in their app, and issue a QR code — or complete it on-device with no code involved.

That is a different job from adding a travel plan alongside your existing SIM, and worth not confusing: converting your main line touches the number you rely on, while a travel eSIM leaves it untouched.

It is a bearer credential: whoever installs it first gets the plan, and it works exactly once.

Keep the email or a screenshot until the plan is installed and connecting. After that the code is spent and worth deleting.

How a provider delivers the code is a small thing next to what the plan costs, but both are worth knowing before you pay. We rank on price per GB by destination — and installing before you fly leaves time for a reissue if anything goes wrong.
