Activation Issues
Activation issues can be frustrating, especially if you're eager to start using your Mint Mobile SIM. If your eSIM is stuck on "Activating" for more than a few minutes, confirm the number transfer finished and check for any ports still in progress.
To resolve this issue, toggle the line on your iPhone or Android device, and remove any old SIM profiles you're not using. Restarting your device and retrying the activation process can also help.
If you're experiencing "No Service / SOS / Searching" after activation, start by powering off your device, waiting 30 seconds, and powering back on. This simple step can often resolve the issue.

Why Activations Fail & How to Prevent Them
Activations can fail for various reasons, but many of these issues are avoidable with a little preparation.
Don't cancel your old service yet. Keep your current line active until Mint completes your transfer, as canceling early can cause your number to disappear from the donor carrier's system and the port gets rejected.
To prevent activation fails, it's essential to collect transfer details first. You'll need three items exactly as on the old account: account number, transfer PIN (or port-out PIN), and billing ZIP. Have them ready before you begin.

A carrier-locked device won't register a Mint SIM, so confirm your phone is unlocked and compatible. Check lock status in your phone settings and unlock with the previous provider if needed.
Some retail units lock to the first SIM inserted under "Reseller Flex" policies, even if they're labeled as "unlocked." This can auto-lock after first use with another carrier.
Using Wi-Fi for the activation process helps the app complete setup and avoids partial downloads or timeouts.
Here are some common reasons why activations fail and how to resolve them:
* eSIM stuck on "Activating"
+ Confirm the number transfer finished
+ Toggle the line
+ Remove old SIM profiles
+ Restart the device and retry
* Browser/App stuck during web activation
+ Switch to the Mint Mobile app on a solid Wi-Fi connection
+ Open an incognito/private window, disable extensions/content blockers
+ Update Google Play services and Carrier Services (on Android)
+ Check for iOS and carrier updates (on iPhone)
+ Sign out/in or reinstall the app
* Phone says "Carrier Locked"
+ Check the carrier lock status in your phone settings
+ Contact the previous carrier to unlock (on iPhone)
+ Check the wording on Android devices, as the language may vary

Here are some key things to keep in mind when porting your number:
- Your old account will be dead once you complete your port, and you'll need to settle up with your previous carrier.
- Most transfers complete in a few hours, but if your information is submitted incorrectly, your phone number could take up to 48 hours to complete, and landlines can take up to 5 business days.
- If you have any questions regarding your transfer, call customer support at 800-683-7392 or chat with us at mintmobile.com/chat.
By following these steps and being patient, you should be able to successfully port your existing phone number to Mint Mobile.
