Topic: Is there a general cause to the various different mobile-data bugs with 10 iii devices?
Some details about the topic:
Mobile data tested before and after device flashing on Talkmobile (UK). Mobile data lost at some point afterwards (after reboot? - difficult to be precise as I WFH with wifi. Mobile data on the same sim still works fine on my old XA2 Plus running 4.4.0.64.
Pv4 and IPv6 mobile data connection works as expected on Xperia X (F5121), SFOS 4.4.0.64, with the same SIM card and same APN settings.
No IPv4 mobile data connection with MNO Telekom Deutschland possible.
If you have a mobile data connection with IPv6-only, the mobile data connection remains if a IPv4-only WLAN connection with internet access is established.
The IPv6 default gateway and the name server entry are also retained.
This means that the mobile data connection is still used when an IPv6 address is resolved.
