Flash a second imei to a dual sim phone

Hi guys,
On surfing the web I found a pretty interesting article Chinamobiles - unfortunately only in German according to it, it is possible to flash a second Imei number to a dual sim phone with only one Imei.
Now, I have flashed my single SIM Huawei p9 lite to become dual SIM with a tool from here on xda-developers. Thus I only have one Imei, whereas the original p9 lite dual sim phones have two.
I've found tools here to change the Imei of a phone, but nothing, also not on the web, on how to add an Imei. - Only that it's possible.
Does anyone know a tool to do that?
Has anybody done it or has experience with it?
Thanks in advance for your answers,
Seth

Hi Guy,

First off, your NA Oneplus 9 Pro is the global ROM(unless you have a T-Mobile version). Second, Global ROM does not support dual SIM yet.

Also, check your sim card tray. On NA version, the 2nd tray has a black bar on it preventing you from even inserting a 2nd sim.

i think even you buy a dual sim tray for oneplus 9 pro, the dual sim is still locked in the software side.

N9750U Dual Sim !

anyone try to put dual sim tray (hybird one) and change the software to any oneUi from other notes 10 + versions which support dual sim ?
