Hello, I have a strange issue with my device SM-G9880. I could not get 5g to work on sim1. It works only on sim2 slot. The option is available on sim 1 but does not connect to 5g. Any thoughts would be appreciated.

Can confirm the same here with the sm-g9880 Hong Kong model. I have a Telstra Aussie Sim that supports band 78 5g. Will only work in second Sim tray. Very strange. I'm guessing this is some kind of bug?

It is a bug, and hopefully can be fixed by a software update

Just to let people know though. Once on the Hong Kong CSC , it doesn't support band 28 aggregation so won't do 4g plus . Another strange thing considering band 28 (700) works by itself.

It supports band 28 (700) but it doesn't pair with other bands for 4g plus like it normally should. Specifically band 1 and band 3 - they normally both pair with band 700 but they haven't been on this firmware.

were you able to get this to work? I want to order a G9860 Taiwan or hk model but won't if I can't use an sd card! Whatsapp and camera pics would rinse that internal storage straight away!
