Do I have to buy a TV Guide Data Service subscription for each Tablo unit?

Tablo's TV Guide Data Service subscriptions are tied to your account, not a specific Tablo device.

In the event that you need to replace or decide to upgrade your Tablo, you can swap the unit attached to your subscription using the REPLACE DEVICE button in the Tablo account portal at https://account.tablotv.com/.

Please note that if you decide to use multiple Tablo units at the same time, each DVR will require a separate subscription.
