I paid how much for SMSes?

My latest mobile phone bill informs me that I sent 907 local SMSes in the last billing cycle. That works out to about 30 messages a day, which is not inconceivable considering that sometimes one message may spill over into several 160-character SMSes.

Nonetheless, 907 is a lot considering that I averaged 500-600 SMSes a month last year. Plus it added about $20 to my monthly bill ($0.05 per SMS, which is also a lot considering that the cost of zipping all that data around is negligible with all the paid-up mobile phone infrastructure in place).

Hmmm ... more WhatsApp, less SMSing.
