No Internet or BIS service needed
This is another great news! TringMe application works even if you do not have internet plan on your Blackberry. All operators offers both Email only or Email+Internet (BIS) plan for Blackberry. Many users does not opt for BIS and only uses Email only plan which is definitely cheaper. The downside of that is that most application will not run on Email only plan. If TringMe's application does not find any data connectivity, it uses Email channel to communicate and enables users to initiate calls even if they do not have internet plan.
