Hi guys, I put a nanosim into the 2nd sim card slot in my Huawei p8 but it did not recognise the card. I cut the card myself to a nano sim so that may have been the issue. But now I canno't actually get the sim card to eject using my sim ejector. Is there anyway to get it out?
I tried ringing technical support but they just said take it to a phone repair shop so I guess my warranty does not cover it.
Another question is can I put a nano sim into the first slot instead of a micro sd?

Just updated my Samsung Galaxy S8+ dual sim edition to Android 9.0 Pie.
I have a tiny sim card extension fitted on my SD card so both my primary sim card and my travel-sim card can be active simultaneously.
the second sim card is thus on the outside of the phone inside a waterproof case.
When booting up I get the following error message before I can unlock my primary sim card:
SIM card tray slot problem
There seems to be something in your SIM
card tray slot that doesn't belong there. Check
it and try again.
If I slide the secondary sim card out of the adapter I can proceed, but there is no option to bypass this.
Hope to reach other dual sim users before they update.
Update, I am late for the party: https://forum.xda-developers.com/galaxy-s9/help/dual-sim-card-sd-card-problem-t3809073/
Best solution in this case is just to find another company for my next device, Sony does have some option to allow Sailfish OS on some of their dualsim devices, so that may be a route to take.
Hello,
Why it is not possible to hack a android phone to store the SIM Card data from the SIM directly in the phone?
I mean somthing like "E SIM" for poor ones. On devices with port for two SIM or one SIM and one Micro SD card that would be a great
solution to use dualsim and SD Card simultaneously. I heared that SIM cards have some sort of "Number" who can not be copied, is that the problem why that does not work?
