App Enables Surfing Over SMS/MMS Through T-Mobile 149

Posted by Soulskill from the wonder-how-long-this'll-last dept.
MrSeb writes "An ingenious browsing hack has emerged: if you have an Android smartphone and a T-Mobile (US) unlimited messaging plan, you can now use an app called Smozzy to surf the web... for free. Smozzy is just a wrapper around the standard Android browser, but instead of requiring a data connection, everything is funneled through SMS and MMS. Whenever you click a link, instead of firing off a packet to a remote web server, a web request is instead sent to Smozzy's intermediate server via SMS. Smozzy forwards the request, downloads the web page you're trying to visit, and then sends it along to your phone as MMS messages — and both SMS and MMS are completely free with T-Mobile's unlimited messaging plan."

        If you do this right, it's just another transport layer. At which point, it's just a variation of "IP over Avian Carrier". Just like any layer you treat as an unreliable datagram, you build the higher level stuff on top of it.

Yes, this would be painfully slow and inefficient, but it is a work around nonetheless.

    • The guy who made Smozzy replied to a bunch of questions on HN [ycombinator.com] There is no encryption between the phone and his service (yet)

      • It's also explicitly noted in the app's Options:

        Confirm HTTPS Requests (checked by default)

        Prompt for confirmation before sending HTTPS requests (recommended as HTTPS requests sent through Smozzy are not secure)

      SMS might be over the control channel, but it's also the lowest possible priority over said channel. In short, not only will the latency be ridiculous and the bandwidth tiny, you'll also experience constantly high rates of dropped packets. It's a neat little project in a 'just to see if you can do it' kind of way, but I highly doubt it was ever meant to be practical.

      Not before T-mo suffers a worse fate than AT&T in dropped calls and such.

      People think AT&T's atrocious dropped call rate is because of lousy signal - that's one reason to get a dropped call, but for AT&T, it's not. It's not even tower congestion (another reason, when the tower simply says it's full and you're just out of reach of the old tower).

      It's control-channel congestion. A phone like the iPhone makes and breaks data connections very frequently (maintaining a data context takes power, so if you only establish, do your tranfer, and tear down ASAP, you can extend the battery life significantly). However, doing so means a lot of control channel congestion as stuff like websurfing will establish a connection to do the HTTP transfer, then tear down while the user browses. Now get a bunch of phones doing that and if a new phone comes in, it literally can't get a word in edgewise to associate with the new tower. And the tower sits there with plenty of channels to offer up bandwidth for voice and data, but a full control channel.

      It happened to T-mo as well - there was an Android IM app that presumably managed to open a data connection right after Android shut it down, causing congestion from the bringup and teardown operations.

      One reason it really only happened recently is the rise of texting. Texting in Europe and Asia is huge, and the carriers had the same problems, but they adapted with control channels that can expand in bandwidth as required. Texting in North America was basically non-existent until the turn of the millennium. So carriers pretty much got stuck with the problem and since it didn't hurt things too badly, they let things be.

      Then the iPhone came about with its reckless (but power efficient) use of the control channel and AT&T suffered big time with control channel congestion. Places with the highest density of phone usage had the highest droped call rates.

      It's why Europe and Asia didn't see the iPhone meltdown that AT&T did, why AT&T can have the fastest network despite the dropped call rates (having spare channel capacity is meaningless if phones can't get at them because the control channel is full).

      Also, MMS isn't sent through the control channel - it's notified via the control channel and the phone's MMS client then establishes a regular data connection to download the attachments via the faster data interface.

    • Wow I flubbed that one and missed a closing tag
    • Its more expensive if you pay per message. Since this plan is unlimited messaging, it's cost per month / bits so the more you send/receive, the cheaper each bit is.

    • SMS is more expensive than Hubble data if you pay per message to send/receive them. However, every major provider offers an unlimited option, usually for around $10 per line. Although if this were to become popular those plans wouldn't last long. Really, this system has problems everywhere except cost: bad latency, horrible bandwidth, best effort transmission, delayed and lost messages just to name a few.

    Not 'too' slow. No, not speedy. But it works. SSL is an issue, so I suspect this is not useful to do any banking with.

    BUT...

    One important item. TMO and everyone else expects you to have a data plan with your smartphone. So this does not get you out of a data plan. It does, however, make that 200MB plan with TMO a lot more useful. By limiting your use of that to say HTTPS and anything SMOZZY doesn't handle, and using SMOZZY to fully exploit your SMS plan, you'll avoid overages (caps and throttling) and incidentally fully leverage your SMS plan.

    Since SMS was always a clever use of signalling, it will be the carriers' response to re-prioritize any excess SMS traffic to ensure network signalling gets through. as far as I recall, they never even promise SMS will be delivered, so if SMOZZY gets out of hand, they could respond as if it were SMS spam. And TMO might, though they might hold off longer than, say, VZW, which I predict would boil your firstborn if you tried this on their network. AT&T would attend the buffet. Sprint would probably quietly block them and deny all knowledge.
