Yes and no. You cannot make a Voice call and send arbitrary data. You
can make a data call (so called CSD) and send arbitrary data. Trouble is
that this is clearly visible to the operator as the call is signaled
differently, so if you are trying to avoid data call costs, it's not
As a mental model, you can think of the Neo as an Linux/ARM based PDA
with an embedded GSM modem.
