sms sending times out too early?

I have now tested SMS failures on the Huawei E367 and the D-Link
DWM-156, but am unable to make any of them fail in the same way as the
MC7710. Both devices return a "failure" status much faster.

But using a SIM card with no subscription I can make the DWM-156 time
out in 13 seconds, which still seems to be too much for MM:

Note that this is not reproducible with the E367, which will return an
immediate 'NotRegistered' status in this case.


I guess I should look more at *why* the MC7710 fails.  I assume this is
related to SMS sending on LTE, which I know absolutely nothing
about. Will look at it when time allows...
