Hi

my question is simple:
On SIM 1 is available only 2G Network and on SIM 2 is available 2G, 3G and 4G Networks

is normal?

if i detach SIM 2 is normal that SIM 1 Always have only 2G network available?

If i want to use 3G networks on SIM 1 i must change fisically the SIM?

Hi,

if you insert two sim cards, one can supports 2/3/4G network, then another one will be just able just support 2G network.
it is normal.
