@NikiMax This is problem, which actually is not related this topic to watch Swisscom TV on move. The two mentioned links are just examples of free platforms that can also be used abroad (but they are not Swisscom related). Free platforms with english-speaking films for sure exist, but it is not clear if there are rights to watch the content worldwide due to licence regulations, so it not Swisscoms task to find out, what is possible and what is not possible. Blue TV itself contains the free platform Blue Play in german, french or italian -> blue TV (if you have the the appropriate subscription). Here you find a plenty of content of which you can switch the language to english (especially if the orginal language is english), an example you can see here:

If films or series contain the abbreviation “En” in the description under “Language”, then you can switch. And believe me, in the three language categories D, FR, IT, you will find tons of film you change the language to english.
