Internal wifi / 3g / 4g modem for a laptop (pci-e), does it exist in nature?

Question

Iron

I wanted to add the ability to work in mobile networks to my favorite laptop. I found on sale pci-e boards with gprs / 3g / 4g chips, but with them the ability to use wifi is lost. Question for those who know:
1. are there boards for pci-e connector on sale with support for the entire set of wifi / 3g / 4g (you need a link)
2. if there are no such boards, is it possible to plug in one pci-e and wifi and 3g / 4g
thank you board

1. Yes, I met. But it is very expensive and you need an additional special antenna for gsm. Hua Wei EM772, GTM671W.
In the harsh reality, you have to choose either LTE or 3G
2. No. Better look for the second one, he often hides near the RAM outside the hatch
