The residential SH3 is available now to new customers taking out a new contract.
If you are an existing customer and you phone up asking for one just because you want one, it’s unlikely you’ll get one. You can’t ask to buy one either, they are provided on loan only.
There are domestic SH3’s available for purchase on the likes of eBay, but they would undoubtedly be classed as grey market routers of questionable origin and if connected to BT, the serial numbers of those routers would become visible to BT and their systems would know that BT didn’t supply the router to you. Therefore, if you subsequently had issues and asked for help, BT could tell you to effectively do one.
The SH3 is a WiFi 6 router, the EE router is WiFi 7 capable and therefore backward compatible with other standards preceding it, whereas the SH3 isn’t WiFi 7 specced. A lot of items that connect to WiFi aren’t even WiFi 7 specced, it’ll be years down the line before everything is.
