what is Tri-band?
More Coverage with Tri-band technology Tri-band technology in your phone allows you to enjoy Cricket service in several coverage areas without needing to use national roaming minutes. Look for this symbol on the back of your Cricket phone to see if your device is tri-band compatible.
If you have a Cricket phone with a "tri-band" symbol on the back:
This means that your phone is compatible with the new technology and that you can use your phone in all Cricket coverage areas.
