Did anyone tried to use Yes on japan telco based xperia? Like those docomo and softbank one.
I got a softbank xperia x performance, flash global totally no signal, flash original japan softbank rom got Yes 4G signal, but ridiculously the signal went off when everytime want to turn on data.

Seller didn't state for Yes 4G so have no idea. I already did a through checking b4 ask

Checked, it should be limited by hardware.
I exchanged my softbank unit with my dad's docomo unit, which Docomo website states support all band, but seems like the phone is not unlocked by Docomo for overseas use, so no hope also :|
It looks like something is preventing the software from connecting the tower. Tower signal is strong.
Band 38 40 is not blocked in OS. It should be blocked by the internal modem.
Afterwards, asked the seller, seller say need to get AU unit in order for Yes to work. (wow you don't expect me to buy another unit!)
Nevertheless, now I switched to celcom's yoodo instead. No incompatible lte bands and 4g only frustrations. Merdeka promotion 62GB rm38. Cheap cheap. No tethering restrictions and no throttling.
