If you are operating under multiple carriers, make sure your carrier information is always up-to-date in the ONE20 F-ELD app. For more information on how to manage your carrier information in the ONE20 F-ELD app, go here: Managing Your Form Header.
If you are operating under multiple carriers in one day, ONE20 recommends that you ask each carrier for your logs before leaving the carrier so you have them in electronic form. You can also choose to email your logs to yourself. For information on how to email your logs to yourself, go here: Emailing Your Logs.
