You will definitely need to use a PCIe to M.2 B-Key adapter. Cell modems are all B key, M-key is only useful for storage as far as I know.
Can you provide info on your pigtails for the cell antennas?
I'm trying to get The RM500Q-GL working in an RB of some sort (wanted to use a wAP-G, but there isn't enough physical space for the length of the card, especially after the PCIe to M.2 adapter). I purchased a LtAP to try and see if it would fit and work; should show up tomorrow. Still don't have antenna connectors/pigtails/adapters for it, as it uses the smaller connector than the 4G-LTE standard Microtik designed around.
Thank you!
Apart from using M.2 SSDs in the RBM33G (and in PCs) I'm rather new to the M.2 word and the various standards, and also the relation to PCI-E.
Ok, then I'll get hold on such an adapter.
Can you point me towards one?
Will for instance this one do the trick?:

I ordered these pigtails:

Like you, from the start I did not pay attention to pigtails as I wrongly assumed the connectors were u.fl..
The world of RF connectors is not easy to get an overview of, as there are numerous new variants with slightly different dimensions. A few hours of googling learnt me that the right connector for the card comes under different names: Hirose W. FL, Amphenol AMMC and MHF4.
LtAP is a nice device with lots of possibilities, hope you get it running.
I'm going for RBM33G with aluminum (RB433-style) casing.
