Can't able to attach 5G Module Telit FN990A40/FN980

Hello Team,
I am tring to insert Telit FN990A40 module to modem slot, but its not fitting and size of the slot on board is comparitively little small.
Could not able to move any further.. Is there any list of modem that only support/fits to our board? if yes please forward the details.
And how can we able to insert the sim if the above problem resolved..
I have attached the picture of our modem
Please provide the resolution as soon as possible, hope team understands..

Thanks,
Navodaya.
