Short answer
You may be able to set up one access on several devices and still be allowed to use only one stream at a time. Your content provider sets the rules. TELOS profiles, app activation and the source connection limit each serve a different purpose.
Device
Is the app available and set up on this exact device?
Source
Does the plan allow the intended simultaneous playbacks?
Household
Are the network and controls adequate at both TVs?
A decision aid for your own access; not a measured device list or a promise of extra streams.
Check simultaneous streams in your household
Compare simultaneous viewers with the number of streams allowed by your TV provider. Each viewer is counted here as one separate stream. People watching together on the same screen share one stream. A TELOS profile is not an extra provider stream and does not expand your subscription.

Three questions behind adding a second TV
Perhaps you want to move from the living room to the bedroom in the evening. Perhaps two people want to watch different programmes at the same time. Or you want the same channel on both screens. These plans differ technically and contractually. First describe which one your household actually needs.
For switching from one device to another, one permitted stream may be enough: stop playback on the first device, then start it on the next. Two independent simultaneous streams require permission from your content provider. The same channel on two devices can also mean two requests. What matters is how the provider counts use, not only how many different programmes are playing.
TELOS provides the player. The app does not sell channel packages or extend the rights attached to your M3U or Xtream source. Buying the app therefore does not prove that two TVs may watch the same access at once.
Registered devices do not promise parallel streams
Separate the terms in your agreement: how many devices may you add or register, and how many playbacks are allowed at once? Are there household, location or device-change rules? A provider may limit these differently. Do not assume another service’s terms apply just because its app runs on the same TV.
Before paying, ask about unclear wording directly: “Can the living-room and bedroom TVs play different content at the same time through my plan in an external player?” If you also want to use a phone away from home, mention that case too. Keep the answer, plan and date private.
A regular streaming-service login is not automatically an access source for TELOS. You need a source type that is explicitly supported. The M3U and Xtream guides explain the required details. A second device does not make a closed provider app an externally usable source.
TELOS profiles separate household selections
On supported TELOS versions, personal profiles help separate favourites and other personal areas. The Apple app describes up to five profiles per Xtream account. That number means personal spaces, not five extra content contracts or a promise of five simultaneous streams.
Check the exact scope under Profiles and child profiles (in German) and on the page for your device. On Apple TV, profiles stay local to that device. Do not assume that favourites or history from the living room will appear on another Apple TV or iPhone.
For children, set up a separate approval of content choices. A profile name alone does not check content. Keep personal areas, PIN protection and the provider’s connection limit as separate items on your list. This prevents a working child profile from being mistaken for permission to add another stream.
Choose the actual app route for each TV
For each screen, note where TELOS will run: directly on the TV or on an HDMI-connected player. Use the official download overview and the relevant product page. In the current TELOS status, native Samsung and LG versions are still under store review; Android TV and Google TV are in preparation. A phone release does not confirm a TV store route.
For a compatible Fire TV device, check the Fire TV requirements. Fire OS 6, 7 or 8 are listed; Fire OS 5, Vega OS and Fire tablets are unsupported. Apple TV has its own tvOS app and setup guide, with tvOS 17 or later listed as the minimum.
An Apple TV app inside a smart TV is not the same as an Apple TV device. Also check app activation and purchase terms for each route you actually use. Activation or another player licence does not change your content provider’s stream limit.
Set up each device separately, then check permitted concurrency
Start on the first device with a familiar channel and confirm that picture and sound work. Explicitly stop playback. Then check the same access on the second device. This first shows whether each device can open the source, without a second connection affecting the comparison.
If both individual tests work and your plan permits concurrent use, start the intended simultaneous playback. Do not change other settings during this test. Record whether the second picture fails to start, the first playback stops, or both begin buffering later. These observations help with the next step but do not diagnose the cause by themselves.
If each device works alone and only shared use fails, ask about the connection limit and how active sessions are counted. Do not rely only on a black TV screen: an attached player may have a different state from the television. Check playback status and use the stop controls provided by that device version.
If both streams are allowed, check the shared network
Two permitted streams also need enough bandwidth together, in addition to updates, downloads and other network use. The bandwidth guide for 50, 100 and 250 Mbps shows how to estimate demand from your sources. A larger plan does not bypass a connection limit.
If only the farther TV buffers, compare its network path first. Good Wi-Fi in the living room does not confirm the connection in the bedroom. Where supported, compare Ethernet without changing the source or player at the same time. For repeated interruptions, use the buffering guide.
To finish, record each device’s app route and result, along with the explicitly permitted number of simultaneous streams. Keep full playlist links and passwords private. This guide reports no in-house multi-device tests and sets no general TELOS device limit; your provider and device version must answer the questions specific to them.
Frequently asked questions
Do five TELOS profiles mean five simultaneous streams?
No. Profiles separate personal areas. The content provider sets the permitted connection limit for your source.
Can I switch between two TVs with one stream?
That may be possible if the device permissions allow it. Stop playback on the first device, then start it on the second. The terms of your source still apply.
Does the same channel on two devices count only once?
Do not assume that. Two devices may create two independent requests. Ask your provider how your plan counts them.
Why do both TVs work separately but not together?
First check the permitted number of parallel connections. If simultaneous use is allowed, examine shared network load and each device connection separately.
Does another TELOS activation raise the provider limit?
No. Player activation and the content source’s usage rights are separate services.
