What's up With Text

Actual Text Message costs are divided between the receiver and the sender

pass-through costs are about 2cents a message once you get to scale

No systems deliver to low-costs carriers ( i.e. MetroPCS )

Obtaining your own short code is expensive and can take months to apply for

Twilio/Tropo can scale for building SMS/voice apps

costs may not be comparable

require a developer to build services on top of the API

Carrier and tech fragmentation is scary/closed system; are open alternatives on the horizon

Sending SMS or having a short code allows people to pull money from the users phone bill to their account, i.e. short code donations.

With smartphones there alternative ways of sending and receiving messages, which can decrease costs

FreedomPhone is a distribution of Android to improve security; IMEI number may be the same regardless.

OpenBTS is based on GNU Radio project and lets you build your own cellphone tower for act $2K-used at burning man or in disaster recovery scenarios
