I'm looking for any reliable ideas for remote pi's using cellular. I started using the free option from freedom pop but they're unreliable. I'm working on a remote solar project and looking for any ideas. This could be a useful thread.

I'd originally suggested gsm modules though that's a bit too low level and the pi is capable of higher level usb modem integration.

You could probably get one of those usb 3g dongles working :)

I found something that may be of interest: https://github.com/jusic/psendurance

Most USB dongles work with enough banging of head against wall.
Sakis3g is quite a useful tool here (although the main repository is a bit up and down over the last few months).
Some of the newer dongles also pretend to be ethernet interfaces, and thus can just started with dhclient on the appropriate interface.

Of course you'll need something like OpenVPN to actually reach through the layers of carrrier grade NAT to be able to SSH into the the thing remotely, but it is certainly all do-able.

I would recommend a 3.8 kernel with the split_fiq patch applied for maximum chance of success.
