It all depends on the data volume and the latency requirements.
For lowish data and latency insensitive I would go with GPRS
if the mobile provider offers it. I certainly know of a similar application
that is rolled out to hundreds of sites using GPRS. The biggest
issue is radio coverage which is usually solved by using external
aerials.
As for the kit to use I know of two large projects that use SARIN
routers have a look at :

Also if its a large project the telco will usually give a good/fixed
rate on the data.
