This Fritzbox receives the phone number of the inserted SIM card, provided it supports mobile telephony including VoLTE (Voice over LTE). It also receives incoming calls to the configured VOIP number(s). For example, from services such as netvoip.ch, sipgate.ch etc. All these numbers can then be received on one or more DECT phones according to the configuration.

According to my research, there is no technical difference between the two versions. It is the same device. The only difference is the scope of delivery and the default settings for the international version for several languages and regions, in short, you can use both, I would choose the cheaper one.

As far as I can tell, that’s not the case. IMHO, it would work as a router for an other cable/dsl modem ( this is going to be my case) but not as an ADSL router

Depends on the mobile phone provider. Quite fast with 5G. But other manufacturers are faster. But Fritz.box has many good features.

Yes, according to our information, the only difference is the power supply unit.

I wouldn't know how to answer your question because I've sold it, Crd.

this is only available at digitec and not in germany Other countries do not necessarily have nationwide router freedom. Since the standards were not necessarily uniformly defined either, AVM developed a so-called "international version" for various countries (except Germany), which harmonises with the Internet connections abroad. Since an international version needs considerably more adaptation than a German version, updates have also taken longer. But now it was decided to combine the standards from the German and international markets. With the current FRITZ! lab version, there will be only one version for all models in the future - a worldwide FRITZ!Box. This will eliminate the difference between international and German. However, the update supply is to be continued. The other country standards are now so far advanced that the adjustments in the future will probably be of a lesser nature. 20849818 is the international AVM FRITZ!Box 6850 5G, International 20002928

I don't know, Just buy, try and return if necessary. 100 days return 😊

Yes, you can use any data SIM in it to access the internet, the ones from Swisscom also work, of course. Or e.g. those from Digital Republic, but the download would not be higher than 300 Mbps. It is simply important to place this type of device as close to a window as possible, but since the WLAN signal is then actually emitted in the wrong place, I would think about switching off the WLAN on this router and working with an alternative mesh WiFi solution, for example. Of course, you could also use WLAN mesh hardware from Fritzbox, but these are usually more expensive than the solution from Xiaomi, which offers a very good WLAN mesh system with WiFi 6 with the AX3000 system. Maybe that would be something? The kit contains two WiFi mesh routers that can manage up to 256 devices, and could also be expanded with additional mesh routers if required. Each router also has an integrated 3 port Gbit switch. Xiaomi AX3000

According to AVM, the SMA sockets are for the supplied antennas, which are responsible for mobile phone reception. However, these can be optionally replaced with external antennas.

No, there are no technical differences between the two articles.

Thank you very much for the message and please excuse the late feedback. According to our information, this is an error. It would effectively be the 5G router. Regarding your query about the price, we set the prices based on various factors, including the purchase price from the suppliers. If two products from the same product range have to be supplied by different suppliers, this can lead to major price differences.
