Common QR code issues during eSIM activation: troubleshooting solutions

During the manual installation of the eSIM using the SM-DP+ address and activation code, similar or identical issues may arise. Therefore, it is crucial to examine the common problems encountered with QR codes during eSIM activation.

"eSIM Error - Invalid QR Code"

The error message "Invalid Code" typically means that the QR code used to install the eSIM has already been used or has expired, provided it was scanned correctly. It's important to understand that in most cases, each QR code can only be used once. Even if the activation/installation of the eSIM is canceled during the process, it's likely that the QR code becomes unusable. This is a security measure to prevent unauthorized use or replication of the same eSIM profile.

It is strongly advised not to delete an already installed eSIM unless certain that it is no longer needed. There is no immediate solution to this issue. In such a situation, you need to contact the service provider who issued the QR code and request a new one, keeping in mind that the ability to issue a new code often depends on their specific policies and service conditions.

Inaccuracy: "Adding cellular plans from this provider is not possible."

When the above message is displayed, and you encounter difficulties setting up an eSIM (adding a cellular plan is not possible), it generally suggests that your iPhone (or iPad) may be carrier-locked.

What is subject to carrier restriction?

When a device such as an iPhone or iPad is subjected to carrier restriction, it means that it is closely tied to a specific mobile network operator, typically the one that sold the device. In this setup, the device can only be used with the services of that specific operator unless it is unlocked beforehand.

For instance, if you acquire an iPhone under AT&T's carrier restriction, it implies that the device can only function with an AT&T SIM card or eSIM. Any attempt to use a SIM card or eSIM from another carrier, such as T-Mobile, Verizon, or any other, would be unsuccessful.

How to check if your iPhone is carrier-locked:

1. Open your iPhone settings.
2. Go to "General."
3. Select "About."
4. Look for "Carrier Lock." If it says "No SIM restrictions," it's unlocked. Otherwise, it might be tied to a specific carrier.

How to Unlock

Unlocking an iPhone (or iPad) is a process solely within the purview of the carrier to which the device is tied. Therefore, the initial step involves reaching out to the respective carrier and submitting a request for unlocking. It's important to note that this administrative procedure may take a few days to complete.

However, it's crucial to keep in mind that certain carriers impose a mandatory waiting period post the device's purchase before authorizing its unlocking. Once this waiting period has elapsed, the unlocking request can be submitted.

Additionally, there are third-party services that offer phone unlocking for a fee. Nevertheless, exercising caution is paramount when considering these services, as they come with potential risks. It is generally not recommended unless thorough research has been conducted on the service provider, a clear understanding of the associated risks has been gained, and there is complete confidence in the credibility and reliability of the service in question.
