Here is another log with a lot of roaming.

There are many OUWCTI withouth OCTI OSSYSI updates. It toggles between 
UMTS and HSPA. connman_netreg_status_notify is called very seldom 
because there is no CREG. So this approach doesn't work good enough.

I think at least updates on OUWCTI should immediately use 
connman_netreg_status_notify.

What about having a separate connman_netreg_tech_notify call? This would 
make the code here much simpler? And Huawei modems could also use the 
same function for tech updates.
