Question [Q] How to get a Sony Xperia VL to support all frequency bands

Hello to the community!

Looking for help regarding a Japanese KDDI AU Xperia VL.
The phone is unlocked and rooted but would not support 3G or LTE data services (in Germany) so far...
Technically the phone should be capable of it (as the V or the AX version) but seems to be limited to the KDDI frequency bands so far. How can I get rid of this limitation?

Flashing an Xperia AX ROM?

Thanx a lot!!

Don't they use CDMA based networks in Japan and not GSM based networks as in the rest of the world?
Wouldn't surprise me, if they didn't include GSM compatible hardware

In Korea and Japan they use different systems. That's easier than saying: Nokia and Motorola are not permitted to sell here.
