Bypass 3G, 4G LTE USB Tethering detection on Android

Your carrier may offer you unlimited 3G, LTE data service as long as its used on the phone, but the moment you try tethering it your PC / laptop, they start charging for it or worse, limit the data.

Koushik dutta, a developer, has figured out a way to bypass this Tether detection used by AT&T, sprint, and others. He released an app which offers user “undetectable tethering” and the app is called  ClockworkMod Tether Alpha.

ClockworkMod Tether doesn’t need your Android phone to be rooted, and allows Windows, Mac and Linux users to utilize the 3G or 4G LTE connection of an Android as if it were a proxy, as opposed to a Wifi/ usb access point router. Technically, it actually spoof carriers checking for the TTL (Time To Live) data coming from a desktop, which is unique for every OS. It modifies the IP packets transferring from PC and changes the TTL values in the TCP/IP header.

The computer app installs a virtual connection which understands how to communicate with the proxy on the phone.

However, app will self-destruct on 7th January 2012 in order to encourage users to purchase the paid the version. Bluetooth tethering is also in the pipeline.

Go ahead and try the Alpha version from here on Google+ post.

  1. I tested this app on Three mobile network, they still detect the tethering. No where in the description of this app on the play store does it say it actually bypasses detection, which it does not.

    • You obviously didn’t bother reading Koush’s Google+ post that was linked to from this article.

      “Tether should work with any carrier and phone, and is not blockable or detectable by carriers[1].

      [1] It functions as a proxy, and not as a NAT/masquerade solution that other tether solutions use. Though carriers can still check for http user agent string, but I have an idea to work around that. They typically check the TTL for desktop values. All usual carrier data charges and quotas will apply, but you will not need a separate tethering plan.”
