I've recently started using thinkpad laptops. There are a lot more hardware support options on these tanks!
I've never used a wwan card on a laptop before
[x] is there a wwan card that supports LTE on both CDMA and GSM
for google fi purposes, I'll only need LTE on GSM
[x] do any wwan cards support SIMs?
the wwan cards plug into the device motherboard, and then the motherboard separately provides a SIM socket. On the thinkpad, the SIM socket is available behind the external/removable battery.
both t-mobile and project fi (from google) are offering pretty decently priced LTE data plans
[x] does project fi data only sim take advantage of both the sprint and t-mobile networks as the nexus phones do?
