Problem with dual SIM - Huawei P30 Pro Questions & Answers

My phone is having issue with detecting sim in slot 2. I have an ee and a virgin sim which both work in slot one fine. I also do not see Sim manager in the settings anywhere. I'm guessing it's a software problem as phone is brand new and its probably a tick box that I can't get to. Any ideas?

VOG-L09 singlesim variant ?
if so second slot is meant/restricted for nimcard only.

Dual SIM Note 8 Poor Network connection

I've got my phone setup with a Fido (Canada) data SIM and MTN (Nigeria) SIM for roaming in the second slot. I am using a sim adapter so a 128gb Samsung memory card is also hooked in. For some reason the MTN roaming SIM will not receive calls, most callers to that SIM card are told the number isn't available. However, if I switch off the second data SIM, the First SIM will then be able to receive calls without any problems. I've taken out the sim adapter and memory card, but this still persists.
Has anyone experienced this before or know a way to fix this?

So the phone is not a dual-SIM phone, it is only with the "adapter"?
It is a dual SIM phone alright. These hybrid dual SIM can either take two SIM cards or one SIM card and a memory card. If you want all 3, then you need to use an adapter to achieve that.

LTE VolTE problem.

I have a Huawei Mate 20 lite model using 2 sim cards. The problem I am having is that I can only have one sim card with LTE and VolTE option active. I need to make the other sim to have both LTE and VolTE option active too. Please any advise on how to fix this is welcome.
I did check if this is a sim card problem and I installed this sim card that cannot get active the LTE/VolTE in another cell phone and in that cell phone I was able to actived the LTE/VolTE. So this tell me if not a sim card problem and it is pointing to a device problem.
If this option LTE/VolTE can be active only in one the sim card, then I would like to know how can I make this change to the sim card I want to hace this option. I tried to swap the sim card and did not solve this problem. Please if anyone have any suggestion please let me know. Thanks.
If you have active LTE on that card and the option is not visible, ask the operator if this model is supported.
Also you can check in the developer options if you can select "lte on two SIM cards",
