Your Beeline app will pair your phone to your Beeline while you're setting up your Beeline and Beeline account for the first time.
If you later unpair your Beeline and then want to re-pair it, the easiest way to do this is to click on the Beeline icon that in the top right corner on the home screen of your Beeline app. Your phone will search for your Beeline and will ask you if you would like to pair to it:
Your phone will then ask you which Beeline you would like to pair to. Select yours.
If your Beeline is on the logo screen tap the top button to wake it up and you're good to go.
Tip: If you have more than one Beeline in your house and would like to check which Beeline to pair to, you can find out your Beeline's number by waking it up while it's unpaired and watching for the number to pop up on the screen.
