No cell reception at home. I have been using SMSFun to send txt/sms. It has been very, very reliable.
Recently they added a "Yes, add this to the live sms feed" option, and it is enabled by default. The smsfun live feed itself has been around longer. If you don't want to broadcast, you have to disable this every time (at least with the free service anyway). This does not bother me a great deal. But anyway, it is a good time to ask:
What other sms services are you using and why? : )
