To sign up and use Sideline, you have to have an active carrier plan on the device you're using since calls route through your carrier number.
iPads don't have calling services associated with them and are not considered a 'mobile' device, hence the reason why we don't offer the Sideline app for your iPad.
However, if you have an existing Sideline account and wish to use Sideline on your iPad or tablet for texting only:
- Visit Sideline Web (messages.sideline.com) on your browser
