Depends where you live. MoreMins lets you buy a virtual phone number for about €4/mo if I remember right, which is wayy cheaper than anything physical you can get anything here in Australia.
Yes. Most modern phones are dual-sim. New Google Pixels, new iPhones, All Xiaomis afaik.
You can give them phone number A and then completely disable that sim out of work hours.
Edit: also you can have “virtual” phone numbers that you just use inside an app on your phone, but they don’t do as much as a normal mobile number so I personally wouldn’t take my chances.
Cancelled Disney+ when it nearly doubled in price, as we’d only bought it because it was only A$8/mo anyway. Also cancelled Kayo when they tripled the price over about a year without informing us that well.
Try slavart dot gamesdrive dot net (or use their server on divolt.xyz)
Their website lets you search for songs and download them, or their Divolt for using a bot that lets you type $dl link-to-song and it’ll send you a download link.
Also the Divolt bot supports Spotify, Qobuz, Tidal, Deezer, and if I remember correctly Apple Music links.
