Ofono modem hardware support?

Hello everybody,

Which modems are supported well by ofono, in your experience?

We are currently evaluating modems, and we would like to know which 
modems cooperate well with ofono. We are interested in modems which 
support a GPRS/UMTS data connection, and voice calls and SMS messaging 
for some use cases; dual-SIM support would also be useful.

We are integrating the modems into our hardware, in various use cases in 
an automotive context, and we use modem modules with integrated RF 
support, so I'm not so much interested about USB sticks or PCI cards. 
But feel free to share your observations anyway!

Many thanks & greetings          August

Cinterion EHS6 is working well for us with data. I can't speak to
voice/SMS at present but this is on my roadmap and I'd be interested in
putting any needed time in to prove this out. Historically we've found
the module itself pretty reliable and the support from Cinterion/Gemalto
excellent.

Regards,

Alex

Thanks for your first answer! I would like to add that we are currently 
using the Telit HE910 module with ofono, as you can see from the emails 
from my colleagues to this list, and we are basically happy with it; 
aside from some occasional minor glitches, it's working well for us, 
especially with newer firmwares. We had the UC864 previously, but there 
were problems mainly with the digital voice interface on our hardware.

Of course, use in a car is kind of a hardcore use case, with constant 
cell handovers, changing signal reception levels and connection 
losses/reconnects, roaming and so on. But on the other hand, this is not 
really different from use in a mobile phone.

Many thanks & greetings     August
