Why is my Mint Mobile eSIM not working?
A Mint Mobile eSIM usually stops working for one of five reasons — your phone doesn’t support eSIM technology or is locked to another carrier, your number transfer isn’t finished, the eSIM profile has downloaded incorrectly, your phone’s software is outdated, or the Mint line is switched off in your settings.
Because Mint Mobile uses T-Mobile’s US network, weak indoor coverage or a local outage can sometimes look like an eSIM problem even when the profile itself is fine. Most issues are quick to identify once you know what to check.
Below is a quick-scan table to help you find and fix the issue.
Symptom | Likely cause | First fix to try |
|---|
eSIM stuck on “Activating” | The Mint line is switched off, number transfer is incomplete, or activation didn’t complete properly. | Make sure “Turn on this line” is enabled, then restart the phone.
|
|---|
“No SIM” or “Invalid SIM” | The eSIM profile hasn’t been installed correctly, or the phone isn’t recognizing it. | Check that the Mint eSIM appears and is selected in your cellular or SIM settings. |
|---|
SOS or SOS only in status bar | The phone is carrier locked, the Mint line hasn’t been selected correctly, or there’s a network/coverage issue. | Turn the Mint eSIM off and back on, then make sure it’s selected for cellular service. |
|---|
QR code won’t scan
| The QR code is blurry or distorted, screen brightness is interfering, or the camera can’t read it. | Adjust the screen brightness and clean the camera lens — if that fails, install the eSIM manually using Mint’s activation details. |
|---|
Data works, calls fail | Voice settings, Wi-Fi calling, network configuration, or coverage may be causing the problem. | Restart the phone and check that the Mint line has been selected for voice calls — then review Wi-Fi calling settings. |
|---|
Nothing works abroad | Minternational Pass isn’t active, international roaming is off, or the destination isn’t covered. | Confirm your Minternational Pass is active and your destination is eligible, then turn on data roaming. |
|---|
💡 Good to know: Many of these problems are common across providers, so it may be helpful to check out Saily’s post on why an eSIM might not be working for more general information.
If you’re traveling and can’t get your Mint eSIM working abroad, Saily is an alternative eSIM that gets you online without QR codes or activation codes. The prepaid travel eSIM covers 200+ destinations and can be set up directly in the Saily eSIM app.
Why is my Mint Mobile showing no service?
Mint Mobile may show “No service” when your phone can’t register on the T-Mobile network, usually because the Mint line is switched off, your device is carrier locked, your plan isn’t active, or you’re outside the coverage area. Try these fixes in order:
Toggle airplane mode on and off. Turn it on for about 30 seconds, then switch it back off and give your phone a moment to reconnect.
Check your Mint line. Make sure the eSIM is enabled and selected as the line for cellular data. On some Android phones, you’ll find it under “Settings” > “Connections” > “SIM manager,” and on an iPhone, look under “Settings” > “Cellular.”
Confirm your plan is active. Open the Mint Mobile app and check that your account and mobile plan are in good standing.
Check for carrier settings updates. On an iPhone, go to “Settings” > “General” > “About” and install an update if prompted. On Android, carrier updates usually come bundled with system updates — look for “Software update” in your “Settings.”
Reset network settings. Save this option for last because it removes saved Wi-Fi networks, passwords, and other network settings.
If you see “No service” while traveling outside the US, check that you have an active Minternational Pass, that Mint covers your destination, and that data roaming is enabled before assuming the problem is with the eSIM.
How do I fix Mint Mobile eSIM activation problems?
To fix Mint Mobile eSIM activation problems, first confirm that your phone supports eSIM technology and is carrier unlocked, connect to stable Wi-Fi, and make sure any number transfer is complete before trying to install the eSIM again. Mint recommends working through these checks before requesting a replacement eSIM.
Check eSIM compatibility. Dial *#06# and look for an EID, then confirm that your specific phone model is eSIM compatible with Mint Mobile. Most phones released in recent years support eSIM technology, but compatibility still varies by model and carrier. You can also check Saily’s list of eSIM-supported devices to confirm whether your model supports the technology.
Make sure your phone is carrier unlocked. Check its carrier-lock status in your phone settings or contact your previous carrier if you’re unsure.
Connect to stable Wi-Fi. A reliable internet connection is needed to download and activate the eSIM.
Finish your number transfer first. If you’re bringing an existing number to Mint, wait until the transfer is complete before installing the eSIM.
Update your phone. Install the latest available version of iOS or Android before trying activation again.
Temporarily disable other SIMs. If your phone doesn’t support multiple active SIMs, remove or switch off an old physical SIM or other eSIM during activation.
Restart your phone. A restart may fix temporary connection or activation problems.
Try the eSIM installation again. Verify that the Mint eSIM appears correctly in your cellular settings — if necessary, follow Mint’s instructions for installing or requesting a replacement eSIM.
On some Android phones, you may also need to enter Mint Mobile’s APN (access point name) settings manually before mobile data will work.
If you’ve tried installing the eSIM more than once and activation still fails, stop reinstalling it and contact the Mint Mobile Line for help.
Why is my Mint Mobile eSIM transfer or QR code not working?
A Mint Mobile eSIM transfer or QR code may fail if your number transfer information is incorrect, your phone is locked to another carrier, or the eSIM hasn’t been installed properly on the new device. If you’re bringing your existing number to Mint, these are some of the most common transfer blockers:
A wrong account number. Check the account number provided by your previous carrier rather than assuming it’s the same phone number.
A wrong or expired transfer PIN. Request the correct PIN or number transfer PIN from your old carrier before trying again.
Billing information that doesn’t match. Make sure the billing ZIP code you enter corresponds to the information your old carrier has on file.
A carrier-locked phone. Contact your previous carrier to unlock the device before attempting Mint activation.
If your QR code won’t scan, check that the image is clear, clean your camera lens, and adjust the brightness of the screen displaying the code. You can also enter the SM-DP+ address and activation code manually. If you’re moving existing Mint service to a new phone, Mint recommends requesting and installing the replacement eSIM through the Mint Mobile app.
Switching between iPhones? Mint supports eSIM Quick Transfer on iOS 18. Keep both phones nearby and connected to Wi-Fi, turn on Bluetooth, and select “Settings” > “Cellular” > “Add eSIM” > “Transfer from nearby iPhone” on the new device. Note that the naming can vary slightly by device.
For travelers who want to avoid QR codes altogether, Saily’s standard setup installs the travel eSIM directly through the Saily app without requiring a QR code or manual activation code.
Do Mint Mobile eSIMs work abroad?
Mint Mobile eSIMs only work abroad in eligible destinations with an active Minternational Pass — so “No service” after landing may mean you don’t have international coverage, not that your eSIM is broken. Before troubleshooting the eSIM itself, check that your destination is covered, your pass is active, and data roaming is turned on.
Mint works like a traditional home-carrier eSIM abroad — your phone connects to a roaming partner’s network, and available speeds and coverage depend on that local network. A travel eSIM takes a different approach, giving you prepaid mobile data specifically for your destination or region.
Mint Mobile’s strength is its affordable US service and simple app-based account management. International travel comes with a trade-off, though. Its data-enabled Minternational Passes cost extra and include fixed amounts of high-speed data, ranging from 1 GB on the one-day pass to 10 GB on the 10-day pass.
An alternative to Mint Mobile — Saily
Travelers who want a separate data option can use a travel eSIM such as Saily. Saily offers built-in security features such as web protection that helps block malicious sites and trackers, an ad blocker that reduces the number of ads you get, and a virtual location that lets you choose from more than 115 locations.
Saily offers prepaid data in 200+ destinations, installs directly through the app without a QR or manual activation code, and provides 24/7 live chat and ticket support. It currently has a 4.7 Trustpilot rating from more than 30,000 reviews.
For travelers who also need traditional calls and texts, Saily offers an optional voice and SMS add-on with a US-based phone number. It supports local calls rather than international calling — with a Global plan, however, you can make calls while traveling in any supported country included in the plan.
How to prep your phone before you travel
A second eSIM can be useful insurance against activation problems when you arrive at your destination. Before you leave:
Check device compatibility first. Dial *#06# and look for an EID, which indicates that your phone supports eSIM technology.
Unlock your phone before the trip. A carrier-locked phone may prevent you from installing an eSIM from another provider.
Install the eSIM before departure. Download and set up your travel eSIM while you still have reliable Wi-Fi at home, then use it when you reach your destination.
Keep two eSIM lines. On a dual-SIM phone, if your Mint line has service at your destination, you can keep it as your primary SIM for calls and SMS codes while using a travel eSIM for mobile data.
Save support information offline. Screenshot your plan details and support instructions so you can access them even if you can’t get online.
Budget your data. Around 1 GB per day can be a reasonable starting estimate for maps, messaging, and light browsing, but streaming and video calls will use considerably more. Not sure how much data you’ll need? Check out Saily’s data usage calculator for a more accurate estimate.
Have a backup ready. You can buy Saily eSIM data plans with data coverage in 200+ destinations through the app before you travel. Saily also includes a virtual location changer, an ad blocker, and web protection for added privacy and security while you’re connected abroad. If you run into setup issues with your Saily eSIM activation process, see the Saily eSIM troubleshooting guide.
💡 Good to know: If you use your travel eSIM as a hotspot, connected devices draw from the same mobile data allowance. Tethering a laptop or tablet can use data faster, so it helps to understand how hotspot data works before choosing a plan.
