Yeah that's a no go mate, I couldn't even do my job if I had a £100 phone it would end up being a cluster fuck as I need to constantly look at spreadsheets, and multiple email inboxes and work through a web Ui portal and none of that is gonna be a good experience on a phone at that price.
I've used enough of those cheap £100 phones be they new or second hand to know for someone who's actually using their phone to do work they are completely unsuitable.
Honestly Plex/Emby/Jellyfin whichever you prefer is a gamechanger because if you have a large library of content then it just cuts the cord from the subscription services.
I've always been happy to pay for them until I went on holiday last January and realised that none of my services were working due to going to a country that was out of the way and the only way to access them was to use a VPN.
So having my own Netflix is a great thing.
Tailscale while doing the above is also really cool
