When working with T-Mobile SIMs, it's important to keep in mind that these SIMs come with an expiration date. The expiration date is 2 years after the SIM was produced, and will typically be printed on the SIM card itself.

Expiration dates are unique to T-Mobile and are not something that AT&T has.

When a SIM card has expired, it can no longer be activated with a new subscription. However, please note that the expiration date does not affect a SIM card that has already been activated.

If you have expired SIMs in your inventory, it is important to replace them with active ones. Remember, an expired SIM cannot be activated.

If someone attempts to activate an expired SIM, their subscription will be stuck in a pending state.

Gigs is currently working on an update that will enable you to identify expired SIMs within the Gigs dashboard. This article will be updated once the change has been implemented.

Until then, you can identify expired SIMs in the following ways:

• By looking at the expiration date on the SIM card

• By calculating 2 years from when you received the SIM

Moving forward, Gigs will be retiring expired SIMs. This means a few things:

• Retired SIMs can no longer be used or activated

• Any subscriptions that are stuck in pending due to an expired SIM will be canceled

• The SIM will show "Retired" as its status in Gigs

If someone attempts to activate a retired SIM, the error message in Connect will display the following:

When they click on the "Customer Service" button, they will be directed to your support.
