It's mostly because mobile networks can't get the size of address blocks they'd need to give every customer an IP address. They all run CGNAT, but that's a pain

It's mostly because mobile networks can't get the size of address blocks they'd need to give every customer an IP address. They all run CGNAT, but that's a pain too. Both Google and Apple require your apps to work on IPv6-only networks IIRC, or they won't be approved for the app stores. Fun fact: Your website loads faster on cellphones if it supports IPv6, because the CGNAT gateway detour adds measurable latency.
