Regarding your questions:

1) I personally use it and it's really good, as I don't want to use additional USB modem or WWAN wireless router.

2) Can't say, as I don't use Fedora.

3) There's a dedicated port for this module. Please make sure, that you have an antenna connectors for module and adapter for a SIM card. Moreover, instead of WWAN module, you can install there a m.2 2242 SSD disk.

4) Both can be enabled and connected, but application will use one at time.

5) I have an extended battery, so it's hard to tell. I guess it have a simmilar power usage as WLAN module (basing on Windows power utilization). Can't say about Fedora.

6) It you don't want to have a problem with whitelist (it prevent system from booting, when unauthorized module is installed), then I look for module on eBay. Make sure, that photos explictly show FRU PN: 04X6014 on module's label. Models without it will not work.

1. the answer depends on your mobile Internet access demands, laptop usage profile

2. use network manager as it supports MBIM network mode

3. actually, x250 might have 3 x m.2 slots. I assume the slot you mean is for both 2242 cache SSD or wwan card

5. power consumption is less than USB wwan modem.
