Sony LIV subscription allows a user to log in on up to 5 different devices with a single account. However, simultaneous streaming is limited to 2 devices at the same time for the Premium plan. For the Mobile Only plan, streaming is allowed on only one device at a time, though login on up to 5 devices is possible. Here is a summary of device usage limits by plan:
- Premium Plan: Login on up to 5 devices, simultaneous streaming on 2 devices.
- Mobile Only Plan: Login on up to 5 devices, streaming on only 1 device at a time.
Thus, the number of devices you can register with your Sony LIV subscription is 5, but you can only watch on 1 or 2 devices concurrently depending on your plan.
