This issue probably requires Developer actions to be solved … anyway I’m posting on General section cause it’s not a properly developer thread …

Since Android 4.1.2 there’s a problem in tethering for all people that has a carrier plan that doesn’t include Tethering. I’m on Vodafone Italy with “mobile internet” plan (2GB/month). I have never had problem with tethering my data connection from my phone to a laptop or tablet but starting from Android 4.1.2 upgrade I noticed that when I activate built in wifi hotspot the APN is automatically and secretly changed from the default one (mobile.vodafone.it) to a new one (web.omnitel.it) that charges my bill with additional costs … It happened to me in the past using branded phone with branded firmware, but after rooting and switching to CyanogeMod firmware the problem was solved … now I’m on an unlocked Galaxy Nexus with CM or others custom ROM …

On 4.1.2 I bypassed this problem using dedicated app “Wifi Tether for Root”, but now on 4.2.1 also this app doesn’t work anymore (ok this is another issue, here you can find more details).

Well … rather bad … I did a lot of research on the web, and here is the most interesting thing I found:

A person working for Roger carrier stated this (see original thread and full post here ):
Android 4.1.2 introduced that ability (and requirement) for Android devices to properly flag when data is for tethering purposes. This is the first time this has been used in a vanilla release of Android.
...
For everyone frustrated by this update to Android: Android respecting a carrier's request to know if data is for a tethered device IS NOT A BUG. IT IS A FEATURE. It's not a feature for users like you and me, it's a feature for manufacturers like Samsung and HTC, so they can in turn build devices that carriers can have more control over.

So, to be clear, THIS IS NOT A BUG. Google INTENDED to respect carrier tethering rules.


So, can someone confirm this behavior? Is there some Developer that can intercept the section of Android OS code that apply this flag to the data download and find the way to avoid this annoying issue??
I want to tether again without pay additional money! I’m paying for 2GB/month! What do you care, Vodafone, how I use it??

Thanks in advance!

EDIT: SOLVED!
After some time someone found a solution, at least for all users with ROOT:
Here is the solution script
Here is a method to setup the script on boot

Hm, never had this happen when I tether my N7 to my GNex, and i'm on a prepaid-card (where something like this would be more likely to occur than on a contract).

I have Verizon and I don't have a tethering plan. I'm on 4.2.1 and I've been able to use the built in tether.

I don't know, AT&T doesn't do this for me.

Can you manually change the APN when the hotspot is turned on?

I can't edit the APN cause I can't see it! After few minutes I'm tethering I get an SMS from Vodafone that says: we remember you that your plan doesn't include data connection using APN web.omnitel.it ... And then if I check my bill detail I can verify a row reporting connection with this APN and additional amount and connection time

Install Chrome or Firefox on your PC, download the User Agent Switcher add-on for it. and change your user agent to googlebot or ipad. That's what I do to bypass Tmobile.

I really don't think it's a user agent issue, I get same problem also connecting an Android tablet independently from the browser ...

I'm on Verizon and running 4.2.1. I tried to tether to a tablet the other day using Open Garden, WiFi Tether for Root, and Barnacle and I kept getting errors on each app and then they'd FC.

Have you tried also the built in tether?

About "Wifi Tether for Root" on Android 4.2 according to some post on the discussion I lnked in the OP:
The application will attempt to mount the file system /system write (rw) to copy the binary file but with Android 4.2 does not work anymore the command "mount -o remount, rw / system"

I don't know if this information can help some developer here to suggest a solution to "Wifi Tether for Root" developers ...

I thought the FCC already ruled that Verizon cannot charge extra for tethering (unless you go over your data limit of course).

Can you tell me how you are doing this please? Is root required on your Gnex? The fact that you are on 4.2.1 may answer that question. My non-rooted gnex is only on 4.1.1 and doesn't seem to have an update available.

I don't pay for tethering on my T-mobile US plan but tethering never stopped working since 4.0 versions all the way now to 4.2.1 takju.
I have a pre-pay plan, so the carrier is not able to charge me anything extra, all they could do is shut off my data plan or tethering, which they never did.

Edit: I'm not rooted in version 4.2.1. I was rooted in some of the previous versions, but can't remember which ones.

Does the built in tether report to Verizon? I'm not trying to get hit with any more fees than they already charge.

No.

^^This guy pays attention. Gold Star.

Ciao Furius!
I think I'm in the same situation as you with Vodafone Italy :silly:

I'm running CyanogenMod 10.1 (so Android 4.1.2) with a Samsung Galaxy S2 and can't get the wi-fi thetering work: all seems ok, other devices can see and connect to the hot-spot, but can't get any data from it...

I thought it was some problems with the nightly builds of CM, but other people are reporting that wi-fi tethering is correctly working.

Now I read your message while searching some information about the Galaxy Nexus (my Galaxy S2 developed a faulty loudspeaker, and I'm considering to get it repaired under warranty then sell it and buy a Galaxy Nexus, I've found it at 269€) and maybe we have the same problem, but I've got Vodafone to lock the web.omnitel.it APN, to prevent costly surprises...

I think problems arise with operators that make distinctions between different kinds of APN (like Vodafone Italy with web.omnitel.it and mobile.vodafone.it) and not with the ones that don't care about the APN you use (to my knowledge, TIM Italy doesn't care about the APN you use)

I'll keep an eye on this topic and let you know if I find some news!

With Vodafone Italy, even if you force the "mobile.vodafone.it" APN, the one for the mobile phone navigation, you will be charged for tethering, using the 4.2.1 native tethering.

See this post for more detail.

BTW, we have to find where google added the "flagging" feature, in the native tethering application.

Do someone have any idea where to find it?

OK ...
It seems that we ( Italian Vodafone users) are the only "sfigati" affected by this issue! Really sad ...

    So did anybody ever make a script?
    What us everybody doing for tethering?

    I'm using "Script Manager - SManager" app:
    - Create a txt file with any text editor (I used Jota, my favorite txt editor), enter the correct script and save the file on your sdcard.
    - Then open SManager, long tap on your script file and select "open as" --> "script/executable".
    - Now add "Su" and "Boot" options, save and you are ok. Your script will run with SU permission at every reboot.

    Enjoy your tethering!

    Excellent news for those getting this issue!

    Type this command from terminal emulator (root required):

    su -c "iptables -tnat -A natctrl_nat_POSTROUTING -s 192.168.0.0/16 -o rmnet0 -j MASQUERADE"

    Found solution here:
