James said that the ISP provider must provide an IPv6 address when the use CGNAT, but mine doesn't.
You are presumably still looking at the Android example.
This is on interest because I use the phone to tether my laptop when needed, so my laptop gets a CGNAT address as well, not an IPv6.
Hmm, I don't think so. When you set up your phone as a hotspot, you usually configure a dhcp range, your laptop will just get a 192.168.1.x address, I expect. and most likely an LL too :-)
No, I don't configure anything, it is on automatic. I just tell the phone to provide an access point. Ah, yes, I assign the password and name. Yes, it is true the laptop gets a LAN address. But the "external" IP is another NAT address, this time the CGNAT. And this carrier LAN has its own gateway that conducts to the true external, public, IP. Everybody on the provider getting a single external IP, or a small pool of them. They never give me an IPv6, as they should. I have seen some providers in Spain that do, I forget which. Some lesser ISP. Not Telefónica, they have a lot of IPv4 addresses to use with their landline clients. No issues. No plans at all to even provide optional IPv6. When asked, they answer with evasive tactics. Other providers use CGNAT even on landline.
I have another machine on a GSM router on a lesser ISP, also on CGNAT. I have not used it in a month, but I fear it will not work at all because the 3G network is being decommissioned. Even my secondary phone, which is my previous mobile, does not get an IP at all
Does telephony work?
On the old mobile, Yes. On the (new) GSM router, it doesn't have a telephone. It can send SMS messages, but as the contract is data only, it can't send SMS. I still have to go there and check things properly. The router itself is 4G, but the provider is a secondary ISP and most of them were using the cheaper 3G network. <https://www.pccomponentes.com/tp-link-tl-mr6400-v530-router-4g-lte-300mbps> TP-Link TL-MR6400 V5.30 Router 4G LTE 300Mbps I have to go and see. -- Cheers / Saludos, Carlos E.
