Samsung S21 FE 5G Network setting issues

[Kishan_Patel_CSE]

We couldn't select both preferred network mode to 5G/4G/3G/2G.

If i set SIM 1 for Data Usage, then i couldn't set up network mode to 5G/4G/3G/2G on 2nd sim even the first SIM have 4G/3G/2G mode set.

Samsung should have to fix this issue in the next update.

Bro, this isn't an issue particularly, after all, the s21 fe doesn't support dual 5g standby. Whichever sim you're using for data this sim only supports 5G even though you're using 4g on that sim and the second one stays in 4G and below.

Hello

I got the same problem

Only one sim card can be set to work on 5G, then the other would Automatically change to LTE and below.

I can not set both on 5G at the same time.

I even can not set 4G on the other sim and it seem doesn't support that. The other can be set to LTE and below

Unfortunatly VERY disappointing.
