I travel in the US.
Have bought Vietnam but it does not have WWAN card.
I really need it.
Do you guys know where in Vietnam to install WWAN cards?

Re: Upgrade WWAN Thinkpad P52

Does the Fibocom L850-GL WWAN card work outside the US? Is there a solution for those who travel a lot?

It will work outside the United States as long as the radio frequencies match the carrier in the foreign country.

LTE/4G Bands supported are:
LTE FDD - B1/B2/B3/B4/B5/B7/B8/B11/B12/B13/B17/B18/B19/B20/B21/B26/B30, B66, LTE TDD- B38/B39/B40/B41
