    Hi,
    Can anybody explain, how the LTE on the apple watch is working?
    Does phone calls come to the watch, because the esim has the same phone number?
    Or is it like the phone call feature of the wifi ipad?

    Would it work to have an only data esim on the watch without a „phone number“ and the calls from the iphone comes to the watch over lte while the phone is at home?

    Ok so it would be possible to use a prepaid esim card from an other carrier with ~250MB data?
    If any prepaid carrier would offer esim cards.

    Yes phone calls come to the watch independently of the phone when signed up for LTE service. In fact, if you have your phone, it should ring both on your watch and iphone. Most companies are using some kind of number syncing software, so you need to have a "phone number"

    If you decide to not sign up for LTE, then it will work like the ipad on wifi.

    AT&T has a little bit of explanation on their site: https://www.att.com/esupport/article.html#!/wireless/KM1223159?gsi=LPjJmB0

    No it would not work. The eSIM stands for electronic SIM, as in on the circuit board and not a separate SIM card. The watch only works with the same carrier as the paired iPhone and must also on the same post-paid billing account.
