Take the 2-minute tour ×  We run a remote system and would like
the servers to be able to alert us to their status via SMS. Is
it possible to setup our own SMS gateway (or our own GSM
network) so we DO NOT have to pay for an SMS provider?  Is this
possible? if so, please let us know what are the required
hardwares and how we get started..  I'm sure this is possible,
because when the operator A want to send an SMS to the operator
B, it do not pay any cent to the operator B. also, there are ton
of online services like: Atompark.com, clickatell, ...etc
please Note: we know how to build an sms gateway using Linux
system, a Modem GSM and a valid SIM, but we are looking a way
that we do not have to pay any cent for sending sms messages...
