Network and device compatibility
SmartLess Mobile is on the T-Mobile 5G Network, so we’ll need to make sure your device has what it needs.
Key factors for network compatibility
To get the best experience with SmartLess Mobile, your device needs to meet a few basic requirements:
-
Network and frequency band support: At a minimum, your device must support LTE Band 71 and Band 12. For 5G access, your device will need to support n71 and n41 5G bands
-
VoLTE support: Required for voice calls over your LTE or 5G connection, including emergency calls
-
Note: If your device relies primarily on 3G for connectivity, you may not have the ability to make voice calls on SmartLess Mobile, including emergency calls
-
- SIM type: Our service works with both physical Sim cards and eSIMs.
- Carrier unlock status: If your device is locked to another carrier, you’ll need to unlock it before using it with SmartLess Mobile.

Keep your device up to date
To get the best performance and avoid network issues, always keep your phone’s software up to date. Many compatibility and connectivity issues can be resolved with a quick update.
Troubleshooting network issues
If you're having trouble connecting to the network, or you’ve lost signal in an area you know is covered, try these steps:
- Restart your device (or toggle Airplane Mode in your device settings)
We know, we know, but we wouldn’t recommend it if it didn’t work.
- Ensure that Cellular Data is enabled in your device settings.
If you’re able to call but can’t access the internet, make sure your data connection is turned on.
- Confirm your account is in good standing.
If your payment method’s expired or you’ve missed a payment, your services might just be suspended – log into MyAccount and make sure you’re up-to-date.
- Update your device software and carrier settings.
Generally good practice that fixes and network improvements are often included in updates.
