Newer Huawei modems, like the E3276 or the ME906 won't support ^SYSINFO, and we
should instead use the newer ^SYSINFOEX. By default, use ^SYSINFOEX when
available, as it provides more information than the plain ^SYSINFO.
E.g.:
^SYSINFOEX:2,3,0,1,,3,"WCDMA",41,"HSPA+"
^SYSINFOEX:2,3,1,1,1,3,”WCDMA”,46,”DC-HSPA+”
