Sim & Mobile Network issues - Xiaomi Poco F1 Questions & Answers

I am using POCO F1 mobile and have sim inserted in both slots. At times the second sim gives the notification as mobile is switched off when someone calls me. They call in my first sim and inform my second number is switched off. If I check my device I could see indication for full signal. I generally re-start my device and this activates the second sim and I get missed call notificaiton.
What could be reason for this. I feel I am missing some important calls as my second number is used for professional connects.

Phone Registers on Network but "No SIM detected"

I'm having a weird problem with my OneX+ where I can make and receive calls, send and receive texts, view SIM messages but when I go to the APN menu to add a new one a toast message pops up saying there's no SIM detected. Due to this, I can't turn on my mobile data
I've tried the tape behind the SIM fix and that didn't work (The SIM is being detected anyway).
Thoughts? Software or hardware related? Anything else I can try? I'm on the stock ROM, unrooted.

Jio sim "mobile network not available" please help me with this

Hello guys,
I am facing a real big issue after updating to the stable android pie release on my poco f1
I am using a jio sim. The incoming calls are not shown on the phone. Whenever a call comes to my number it never shows on the phone the caller will hear the dialer tone as normal
Also when I try to make a call it shows a message mobile network unavailable, mobile data and sms works fine all this time.
When I reboot the phone none of the issues are there for 15 to 20 minutes then it comes back.
There were no issues when i put the sim in the second sim slot but I need to have the same card.
I am really frustrated about this issue, I have missed many important calls as it never showed up on the phone
I cannot find any one else facing this issue. What could be the reason for this ? I hope it's some kind of software bug that can be fixed.
Please help me to fix this guys
Thank you

[Q] Quick question on a dual-SIM issue

If I am in a call on SIM1 and somebody else is calling me on SIM1 I can see the 2nd call and the caller also gets a notification if he is on the same network or some busy signal after some time if not.
However if I am in a call on SIM1 and somebody else is calling me on SIM2 there is no info on my side and the caller gets a message that I am not in the network or the phone is turned off. That is normally expected for dual-SIM dual-standby but all such dual-SIM phones that I have seen can (as long as you let them know the numbers of the 2 SIMs and you activate a specific option) do a small trick - right before you get into the 1st call (SIM1 above) the phone sets call forwarding from SIM2 to SIM1 and that way you get a call waiting when somebody else calls on SIM2 and he gets a busy signal or similar. At the end of the call any call forwarding added by the phone is of course removed.
The question is of course this - does Poco F1 has such an option and how do I activate it?!

Need help, dual SIM (standby) intermittent "no network connection"

Trying to solve a problem for a customer at work, dual SIM standby device (kazam trooper) experiencing problems on one SIM only, when trying to make outbound calls, only works roughly one in ten times. 90% of the time will get "not connected to network" error. Incoming calls are always fine, and inbound.amd outbound texts also working okay. No issues with mobile data. Previously worked fine for outbound calls. Nothing changed, SIMs still I'm same slots. Ran through SIM management and mobile network settings with a fine tooth comb. Unable to find anything obvious.
Out my.depth with dual.sim, please help. Could having mobile data enabled on SIM2 affect SIM1 ability to make calls?
Sometimes new upgraded sim card is a solution. Ask operator for replacement its free of charge.
