Because of the 160 character limit on sms my company communicates our outages by MMS which has a limit too but it is much higher I am thinking 400ish but this also includes text in the subject line. We had tested with Verizon reps for a solution for about a week and found that since not everyone has a bb(they can't receive emails per say on their devices) mms's would be the best solution. We haven't had a problem since.
