I have an X1 Yoga 20FQ with Windows 10 Enterprise 64-bit and a Sierra Wireless EM7455 WAN card that came with the unit from Lenovo and an AT&T micro SIM card (also in the unit when it came from Lenovo). I also have the latest Lenovo software for the Sierra Wireless card (v. 7.47.4743.0105) from the Lenovo web site. The WAN card will connect to HPSA on AT&T (using the "default APN" and "broadband" in the Win 10 settings) but it will not connect to AT&T LTE. The AT&T web site at https://www.att.com/esupport/article.html#!/wireless/KM1218316 says to use NXTGENPHONE as the APN, but when I input that as the APN the card does not see it at all. I know that NXTGENPHONE is the LTE APN because that is the APN that my cell phone uses for its LTE data connection. AT&T tech support told me I the Windows 10 and NXTGENPHONE APN settings are correct and the AT&T diagnostics show I an LTE connection is available to me.
I realize that there can be sources for this problem (Win 10 or AT&T) but I thought I would ask here to see whether anyone has experienced the problem or has a solution.
