SMS arrive late

@Tawa

Both SIM cards are already using 2G/3G/4G and have 4G as the preferred network.

As far as I know only one of the SIM cards can use 3G or 4G at a time and the other one will be in 2G only. Also note:

@Johannes

this setting seems to follow the SIM around. To switch, you’ll need to set the SIM you don’t want to use 4G on anymore to 2G only first, and then the other one to 4G.
