if it's only used to send text messages, it's probably better to get one
of those pre-paid simcards with no subscription.  we have a monitoring
system set up with with nagios and gammu and some bottom-of-the-barrel
nokia phone which sends out sms's for the more critical alerts. i
don't think we pay much more than $50 a year for sim card recharges.
