Very interesting hack.

I've been trying to access the voice settings to modem-dial for a while, but I didn't think to (ab)use SMS this way.

Why T-Mobile only, though? In theory, you should be able to use this to talk to any SMS gateway, but you're going to end up paying on the gateway side ;(

So, I looked at this list: http://en.wikipedia.org/wiki/List_of_SMS_gateways

Of the four major US providers, T-Mobile and Verizon are the only ones with MMS gateways (I use MMS to send the responses) that don't require a sign in by a customer (I only have T-Mobile myself). I tested Verizon's MMS gateway with my friend who has Verizon cell service, but it didn't seem to work for some reason.

One of these days, the network providers are going to stop putting arbitrary labels on their data, as though "voice", "text" and "data" are not all travelling through the same towers and pipes.

Well if you look at it, unless you use "text" for "surfing" like in this app, it actually does not cost much to the providers. You can not type all day, can you? So by "unlimited" text all they are saying is that you will tire yourself texting say about X SMS and thats it per day.

1000 SMS * 160 chars * 2 bytes each (arbitrary) = 320000 bytes. Thats just 320KB. Thats cheap isn't it? Can you type more than that per day?

Great. Now we need a way to send IP packets over a mobile voice call (using the same principles used by old-fashioned modems).

That's surprisingly hard to do ;( Neither android nor iPhone give access to the voice stream.

HP Labs India has created similar (same?) technology called SiteonMobile some time before. http://www.siteonmobile.com/ http://www.readwriteweb.com/archives/hp_launches_siteonmobil...

I saw this when I was googling around to see if anyone had already done this, but I was kind of confused by what exactly it is. I don't think it's the same thing.

Good to know.

Do you use compression at all or is it straight uncompressed HTTP via SMS? Or something else entirely? This is wonderful for it's creative (mis)use of texting...

The requests (which are just URLs, and any postdata/cookies if applicable) are sent to my server via SMS. The responses are sent back to the phone via MMS, in up to 5 (I think?) segments. I download the webpage along with all resources (stylesheets, images, etc.) and put everything in a zip file. I encode the zip file as a PNG (each RGB pixel is 3 bytes of the zip file) and send the PNG in the MMS.

That's even more horribly wonderful than I expected! I suspect you'd get a 4.0 if you went for a degree in Southern Engineering.
