"This code is no longer valid" — what it means

"This code is no longer valid" means your eSIM activation code has already been consumed. Either because the QR was scanned successfully on a different device, the install completed silently and you didn't notice, or a previous failed install attempt registered as a consumption on the server side. The fix is straightforward: email support@eflexsim.com with your order number and ask for a fresh QR. We re-issue within 4 hours at no charge.

Below: why activation codes are single-use, the most common scenarios for accidental consumption, and how to recover.

Why activation codes are single-use

The Eflexsim QR contains a one-time activation token. Once a phone successfully reaches the activation server with that token, the server marks it consumed and won't accept it again. This is standard across the eSIM industry. Every major provider (Airalo, Holafly, Truphone) does the same thing.

Why single-use:

• Prevents fraud. If QRs were reusable, anyone with a screenshot could install your paid eSIM on their device.
• Prevents double-billing confusion. A consumed QR means one device gets the plan. Without that lock, two devices could install the same plan and the provider couldn't bill correctly.
• Standard telecom protocol. The underlying eSIM standard (GSMA SGP.21/22) defines single-use activation as the default model.

The implication for you: if you have one Eflexsim plan, you can install on exactly one device. Trying to install on a second device after the first install fails with "This code is no longer valid."

Common scenarios for accidental consumption

A few patterns we see often:

1. The first device install succeeded silently. You scanned the QR on your iPhone, the install completed in 30 seconds, and the line appears in your Cellular settings. But maybe you didn't notice, or you didn't realize the profile downloaded successfully. Then you tried to install on your iPad or a backup phone and saw the error. The first install used the QR; the second fails.

To check: Settings → Cellular on iPhone (or Settings → SIM manager on Android) → look for an Eflexsim line. If it's there, the install succeeded on that device. The QR was consumed correctly.

2. A family member or roommate scanned it first. If you forwarded the activation email to someone (or someone else has access to your email), they might have installed the eSIM on their phone without telling you. The QR is consumed by their install.

To check: ask anyone with access to your email account. If nobody admits installing, email support. We can check which device the install registered to.

3. A failed install consumed the code. Occasionally an install fails partway through but the activation server still marks the code as consumed. The phone shows "Activation failed" but the server thinks it succeeded.

To check: if your phone shows no Eflexsim line and you're confident no other device used the QR, this is probably what happened. Email support and we'll verify on the server side.

4. You scanned the QR multiple times in rapid succession. Tapping "Install" twice on iPhone before the first install completed can sometimes cause this. The second tap registers as a separate activation attempt that fails because the first one already consumed the code.

To check: look at your iPhone's Cellular settings. If a line exists, the first install worked. Ignore the error. If no line exists, treat as scenario #3 and email support.

How to get a fresh QR

The recovery flow is the same regardless of which scenario applies:

1. Email support@eflexsim.com from the email address tied to your Eflexsim account.
2. Subject line: "Need fresh QR. Code marked invalid" (or anything similar).
3. Include your order number.
4. Brief description of what happened. E.g., "Tried to install on iPhone, got 'This code is no longer valid.' Don't see the Eflexsim line in my Cellular settings."
5. We respond within 4 hours. If we can confirm the original install didn't actually take effect, we re-issue the QR.

If the original install DID succeed on some device (a family member's phone, an old phone of yours, etc.), we can't re-issue. The plan is already in use. The path forward in that case is to either move the eSIM to the device you want (via eSIM Quick Transfer on iPhone if both devices support it), or to buy a new plan.

Preventing this from happening again

A few habits that avoid the issue:

• Install on one device, scan once. Don't experiment with the same QR on multiple devices.
• Don't share the activation email unless you specifically want someone else to install your plan.
• Wait for the install to fully complete before tapping anything else. The "Activating" stage takes 30-60 seconds. Don't interrupt it.
• Check Settings → Cellular after install to confirm the line appeared. If it did, the QR worked even if the on-screen prompt was confusing.
• Don't keep screenshots of QR codes in shared photo albums. If you back up photos to a family iCloud account, a relative could accidentally install your eSIM.

For related install errors, see "Unable to activate cellular service" for cases where the install itself fails, "Cellular Plans From This Carrier Cannot be Added" for carrier-lock issues, and QR code won't scan for camera-related scan failures.
