The speed is strongly dependent on the reception you have and the subscription. Go with your mobile phone exactly where the router will be and do a speed test there (with the corresponding SIM card in the mobile phone). This will give you an approximate value. To be on the safe side, subtract 20% from this; you will always lose some speed over wifi.

I have a Sunrise 5G sim card in it, I know the router is only 4G capable. I am totally dissatisfied with Sunrise (reception & speed) and will cancel my subscription.

I fully agree with Czerwy and also recommend reading this article. It's not meant to stop you from buying, but you just have to be aware of it:

My experience with this router. It is in my holiday home and runs with a Sunrise subscription, which is limited to 2MBit. However, this limit is often not reached, but I see the problem with the poor coverage by Sunrise at the destination and not with the router, because there are definitely phases where these 2MBit are reached. However, I have yet to check with Sunrise, as this can only be done on site and so far I haven't had the time during the holidays. But I think 2MBit is probably not exactly what you have in mind.
Otherwise, this device works very reliably. Availability has always been 100% so far (no failures, no resets or powerdowns necessary, etc.).

Hi All thank you for the great responses! i have bought the better model that supports 4G+
and have added there my experience
