During the explicit access technology check, the plugin would request specific 2G (OCTI) and 3G (OWCTI) technologies explicitly. Some devices (like Nozomi) don't support the AT_OWCTI command, which leaves us with only AT_OSSYS for determining whether the device is registered with the 3G network or the 2G network. So like the unsolicited mode change handling code, when requesting access technology explicitly, ask for generic 2G/3G tech first, and then get the specific tech. If the device doesn't support explicit 3G tech then at least we have the generic 3G tech from OSSYS to use.
