Go to reply no.
with major Sg telecom discontinued 3G network, my mi note cant have 2 simcard turned on at same time (even with manual network search)

i can only enable the simcard which connected to "internet" & another will be in "no service" status.

Any solution as I keep missing my calls...

Mi note can only operate under 4g+2g for dual sim. Since 2g has been discontinued, you can't use dual sim. Please upgrade to 4g+3g compatible newer phones.

My Redmi Note 3 also has a similar problem since May. Dual SIM (4G Singtel + 2G China Unicom) can't register to cellular networks at the same time after upgrading to MIUI 8.2.1.0. If I want to receive calls/SMS from one SIM, I have to set that SIM as default for Dial & Internet.

The telco websites say 2G SIM still can be used as long as it is in a 3G+ handset. This is correct, because my 2G SIM still can receive SMS when set to default in Redmi Note 3. However, it can't connect to network when not set to default.
