This is a legacy article. 4th Generation Tablo DVRs do not need or use a subscription service. If you are making the switch from a legacy to a 4th-generation device, you may cancel your services tied to your legacy Tablo device.
Legacy Tablo TV Guide Data Service subscriptions are tied to your account, not a specific Tablo device.
If you need to replace your legacy Tablo with another legacy model, 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 legacy Tablo DVR will require a separate subscription.
