My ISP has no problem on phones. They use a 10.*.*.* address. ISP Natting. From their point of view, that is not a problem.
My phone's IPv4 address is 192.0.0.4, which is used for 464XLAT.
Mine is 10.190.*.*, after disabling the WiFi.
Plays havoc when I have to tether my laptop and use gmail with it - google thinks I suddenly moved 800Km north or 300 west abd blocks my account.
Surely that is something else? otherwise people would always have trouble when travelling.
It is a consequence of ISP grade NAT. I get the external IPv4 address of their CGN gateway, sometimes Barcelona, sometimes Granada. Geolocation based on IP address breaks, so google thinks it is some hacker accessing my account from those cities, and blocks the access.
I have travelled to 4 different countries, 2000km apart, since beginning of the year, never had that problem, whether on a local wifi or occasionally with data roaming.
With one of my three google accounts, I get it every time I travel. With the other three, occasionally. It is considered a feature. just google "when I travel I get a gmail security alert" One example: <https://www.reddit.com/r/GMail/comments/b7w0vc/how_can_i_avoid_critical_security_alert_when/> +++.................. I use IMAP to access my gmail account (via Thunderbird) and I have the following problem: whenever I connect from a "new" location, gmail blocks my access, and requires me to then log in via the gmail web interface and go into the security page to let it know the connection was by me. I also receive an email that says: "Sign-in attempt was blocked for your linked Google Account - Someone just used your password to try to sign in to your account. Google blocked them, but you should check what happened." I travel often, and every time I connect from a different hotel wifi network this happens, which is very annoying. Is there any way of telling gmail to disable this check? I should be allowed to connect from whatever IP address I want without gmail blocking me every time. ..................++-
And of course, getting a 10... address means people can not connect to me. VoIp might not be possible, I have not tried. Gaming...
VoIP works just fine. I have had people in home office with Linksys SPA phones hooked up to our Asterisk, since 2008 or 2009. Works very well, even back in the days with limited bandwidth.
With Carrier Grade NAT? I thought you were using IPv6. If your phone gets a 10.*.*.* address, you are on CGN. I guess you aren't. I am.
Gaming also works just fine - ask my son. He even ran his own Minecraft server for a while :-)
The vast majority of people are still on private IPv4 addresses, behind a NAT'ing router/firewall. If gaming and VoIP was a real problem, we would have heard about it :-)
