What are the main benefits of TeamViewer Add-On Session Channel?

The TeamViewer Add-On Session Channel expands an existing Premium or Corporate subscription with one additional concurrent connection, letting a further technician run a remote session at the same time. It adds capacity only, so the remote control, file transfer, and unattended access of the base license stay unchanged.

Parallel Support - Lets another technician connect during peak load.
No Downtime - Avoids session limit reached rejection during busy hours.
Immediate Scaling - New channel activates instantly after the order.
Flexible Growth - Add any number of channels later.
Team Visibility - Channel usage view identifies who is connected.
Cost Control - Buy only the channels you actually need.

What is the TeamViewer Add-On Session Channel?

The add-on session channel adds one extra concurrent connection to an existing Premium or Corporate subscription, so one more technician can run a remote session simultaneously. A channel behaves like an open phone line: while it is in use, that slot is occupied until the session closes. It does not add software features, it only raises how many parallel sessions your account can hold. The extra channel becomes usable right after ordering, with no manual activation required from you.

Which TeamViewer licenses support add-on session channels?

Add-on channels apply to Premium and Corporate subscriptions, which can be expanded by any number of extra channels, while a single-channel Business license is not built to scale this way. A Premium license starts with one channel and Corporate starts with three, and each add-on channel increases that count by one. Only buy this add-on if you already hold an eligible Premium or Corporate plan, because a channel cannot run as a standalone license. If you are on Business and need parallel sessions, you upgrade the base plan rather than stack channels.

What is the difference between a channel and a session?

A channel is one concurrent connection slot, whereas a session is a single remote-control or meeting connection running inside it. One channel can hold several sessions opened as tabs from the same computer, but a second computer connecting at the same time consumes a separate channel. Corporate includes three channels, so three different computers can run sessions in parallel, and a fourth simultaneous computer would need an added channel. For teams supporting several customers at once, the channel count, not the session count, sets the real ceiling.

Does the add-on session channel include mobile device support or new features?

No, an add-on session channel does not include mobile device support or unlock extra features, and connecting to iOS or Android endpoints requires the separate Mobile Device Support add-on. The channel purely increases concurrency, so unattended access, file transfer, and remote control work exactly as on your base Premium or Corporate license. Buyers sometimes assume more channels mean more capabilities, but the only change is how many sessions can run at once. If you need to control phones or tablets, budget for the mobile add-on on top of any channels.

What happens when all channels are already in use?

When every channel is occupied, the next person attempting to connect receives a session limit reached message and is blocked until a channel frees up. A channel is released as soon as an active session is closed, so a forgotten open session keeps that slot busy. Administrators can set an inactive session time-out that ends idle sessions automatically to reduce these blocks. Adding a channel removes the bottleneck permanently for that extra simultaneous user instead of relying on colleagues to disconnect first.

How fast does a new channel become active?

A newly purchased channel is enabled immediately and works without any manual activation on your part. TeamViewer applies the change to your subscription, so the extra concurrent session is ready right after the order is processed. This matters for support teams that hit their limit mid-shift and cannot wait for a manual license update. You add and manage channels in the Customer Portal under Subscriptions, then Manage subscription.

Frequently asked questions about TeamViewer Add-On Session Channel

Can add-on channels be reserved for specific teams?

Yes. TeamViewer's Channel Groups feature lets administrators allocate channels to defined groups, so one team's work does not consume another team's connection slots. This is useful when support and sales share a Corporate subscription and each needs guaranteed availability.

Can you see which technician is holding a channel?

On Windows, open Help, then About TeamViewer, and click Channel Usage to see the TeamViewer IDs currently in a session. TeamViewer shows the device ID only, not a device alias or the signed-in user, and this view is not available on macOS or Linux. It helps you locate a forgotten open session that is blocking a channel.

Can two technicians connect to the same computer at once?

Yes, but each connection to that device consumes its own channel from your license pool. Two technicians viewing one machine together therefore use two channels, so plan channel counts around simultaneous connections rather than around the number of target devices.
