Mobile carriers crack down on tethering

Want to tether? Prepare to pay more or find an unauthorized alternative.

It’s most commonly associated with linking a laptop to a data-enabled phone so a user can take advantage of the phone’s Internet connection.

Tethering can have a significant impact on mobile networks since tethered computers tend to use up a lot more bandwidth than mobile phones. This was likely one of the reasons AT&T was so slow to allow the tethering functionality of the iPhone on their network (it appeared more than a year after Apple announced the iPhone’s tethering capabilities.) And when AT&T finally did open up their network for tethering, users had to pay $20 extra per month for the feature.

Now we’re seeing AT&T sending warning notices to users it suspects of using unauthorized tethering apps and Google allowing mobile carriers to block these kinds of apps from appearing in the Android store. While many have complained about these actions, it’s not surprising that the carriers would try to limit tethering to sanctioned apps and users who have opted to pay more for tethering functionality. Allowing jailbroken iPhones to tether or Android apps like PdaNet, Easy Tether, and InternetSharer that facilitate tethering without the carrier’s approval is seen by the carriers as taking money out of their pockets. (Google appears to be allowing carriers to filter the Android store to block these apps for their users, but the apps are still available and installable).

The cat-and-mouse game between carriers and unauthorized tethering is still going strong, however. For example, here’s a recent tweet from the folks behind PdaNet:

3.0 adds a feature to hide tether usage. Most users do not need to turn it on unless you have received a message from such as T-Mobile.less than a minute ago via web Favorite Retweet Reply

This really all boils down to the fact that “unlimited” has a unique meaning in terms of mobile data plans. Cellular carriers have long been criticized for liberally using that word in situations where the service isn’t truly unlimited, and their desire to make users pay more for tethering is another example of how that unlimited data plan you thought you had, really isn’t unlimited. Many have faulted AT&T for their network issues and how long it took them to officially allow tethering, but at least they’ve clarified their data plans and language — you won’t find the word “unlimited” in their rate plan descriptions anymore.

Where does this lead? Even though customers have made it clear they feel tethering charges are unfair, the carriers have made it equally clear they plan on monetizing this feature as much as possible. With both AT&T and Verizon clamping down on unauthorized tethering, the climate for people who want to tether for free will continue to get more restrictive. But it’s important to note that unlike the situation with AT&T and iOS devices, where you must jailbreak the device to get around the carrier’s tethering restrictions, on the more open Android platform there will likely always be free tethering options for those who are willing to go outside of the official store for apps and don’t mind breaking their carriers’ terms of service.

    Maybe you should change ‘Mobile Carriers’ to ‘ATT’ in your title? :^)

    Outside the US (aka “most of the smartphone market”) things aren’t so bad. In Canada, Rogers allows tethering (no extra fee) for any data plan 1 GB/month or higher (I pay $35/month for 6 GB, which I’ve never figured out how to use up even with tethering).

    If you own even a non-rooted Nexus One or Nexus S, you can tether even on a 512 GB/month data plan, since Rogers doesn’t control the software on those phones.

    Can someone tell me where I can buy an unlimited electricity plan please!

  • Bruce Stewart

    @MrF, I don’t think most people’s complaints about the carrier’s tethering policies are around their ending of the unlimited aspect of data plans, but more about them charging more for data that’s within the limits of an existing plan but used in a slightly different way. Sort of like if your electricity company charged you extra to use your electricity to recharge batteries or something like that.

  • Bruce Stewart

    @Sean, you’re right that AT&T has pretty much led the way in charging a lot and cracking down on tethering, but Verizon is doing the same thing. Unfortunately the rumors that Verizon would offer free tethering to iOS users when they finally got the iPhone, as a competitive advantage over AT&T, didn’t pan out and Verizon matched AT&T’s $20 monthly fee to make use of this feature.

    The cell companies may consider unauthorized tethering as taking money out of their pockets but do they really have the RIGHT to charge for tethering

    sure if you use their built in tethering app and go through their proxy server than they can charge you

    but morally and ethically (terms of service and other legal BS aside)

    does a cell phone company really have the right to charge for a hardware function of the phone that can be accessed with third party software that (DOES NOT USE THEIR TETHERING SERVICE) but rather sets the phone up like a router.

    so 3rd party tethering does not use hack or otherwise abuse the “”tethering service”” but rather uses a nat style routing system so in theory 3rd party tethers the phone is doing all the talking and routing not the computer hooked up to it.

    so when you think of it this way isn’t tethering nothing more than the biggest SCAM of all time.

    Ok, who’s had to deal with AT&T lately?  Last month I received a nastygram from them accusing me of tethering.  I called.  They ‘detected activity’ on me.  I filed with the FCC…

    According to Jean, office of the president, after talking to the billing office, they have determined that due to the AMOUNT of data used I must be tethering. No, I have an unlimited plan and listen to iheartradio and 5-0 radio around the clock.. (plus Facebook).  

    If I don’t immediately drop my use, they’ll switch me to a 2 gig tethering plan…  FCC didn’t do anything so far, where do I take it next?  Including class action
