Senator Herb Kohl, Chairman of the Anti-Trust Subcommittee of the Senate Judiciary Committee sent a letter this month to the four major wireless carriers, AT&T, Sprint, Verizon, and T-Mobile asking them to explain the increase.

Carriers limit the number of characters in a text message to 160. Assuming a maximum of 140bytes stored per message, that means that if you were charged the same per-byte rate to download a 4MB song, you would pay about $6000. Nothing has changed particularly in the cost of providing the service, however, companies have the right to charge whatever they can get away with.

The odd thing is that math. We have a phone where text messages are 20 cents each, yet megabytes of downloaded data are 1.99 each. If we want to use Instant Messenging applications provided on our phone, they use text messages as opposed to using data time so they can charge more(We’re Verizon customers, in the interest of disclosure).

Kohl has asked for a response by October 6th. Some experts feel the increases may be a reflection of the decrease in competition as the four major players absorb smaller regional providers.

We look forward to hearing the response from the providers and hope it sparks some sort of change. The current system is ridiculous.
