Data Throttleing Workaround

To all my friends with T-Mobile~ if you have a smartphone & a data plan, I've discovered a workaround for the data caps on the newer 4g plans. The newer phones come with a certain APN, or access point name, pre-programmed into them, kind of like a proxy that your phone goes through to connect to the internet. This specific APN allows the company to track your data usage. What I did was change it to a different APN that they don't keep an eye on. I've been testing this trick for about 6 weeks now & it definitely works. I've been purposely gobbling data like crazy all month just to see if they catch me(I'm at my 5gb limit already), but the T-Mo website only shows that I've used about 100 megs(which was only caught because I flashed a new ROM a couple weeks ago & forgot to change the APN till the next day). EDIT: As of this posting, my monthly allotment has rolled over, and despite using data all day long for several days, the meter on T-Mobile.com is still at 0mb :}

Step 1- if you have the T-Mobile "My Account" app on your phone- DELETE IT. Freeze it if you don't wanna delete it altogether, but either way get rid of it. I've been getting reports that this trick is not working for people with this app installed, and I think it's because it's measuring your data usage on the phone & then reporting your usage back to T-Mobile regardless of what APN you use. So kill it!!!

Step 2- on your phone, go to your settings. FYI- these settings might not be EXACTLY the same on every phone, but you should have the same basic information fields as the ones here. Open up wireless & networks, then mobile networks, then access point names. You should see T-Mobile US or something like it, and the APN should be epc.tmobile.com. This is the monitored APN. Create a new APN with the following settings(Settings>wireless & networks>mobile networks>access point names>menu key>new APN):

Name: whatever you want, I named mine T-Mobile 2

APN: internet2.voicestream.com

Proxy: leave blank

Port: leave blank

Username: leave blank

Password: leave blank

Server: leave blank

MMSC: http://mms.msg.eng.t-Mobile.com/mms/wapenc

MMS Proxy: leave blank

MMS Port: leave blank

MCC: 310

MNC: 260

Authentication type: leave blank

APN type: default,supl,mms (or internet + mms, if that's the setting your phone has)

APN protocol: IPv4 (if your phone doesn't have this, don't worry)

Once you input these settings, hit menu & then tap save. Go back to the APN screen, select the new APN, and enjoy your TRULY unlimited data. This APN will bypass the data tracking while still allowing you to enjoy full 4G speeds :3

FYI I've only tested this on an Android phone, but AFAIK it should work on any 4G T-Mobile phone that allows you to change the APN settings.

And FFS, keep your big fat mouth shut about this. Don't mention it to anyone at T-Mo, we don't want this getting out so they get wise to the loophole. Some might call this stealing, but we as customers PAY for unlimited data every month and its our right to get the services we pay for. Yes, the plans clearly state that you're paying for a limited amount of 4G, but I don't think that gives them the right to knock us down to sub-2G speeds once we use up our 4G allotment. If they just bumped us back down to 3G it wouldn't be a big deal, but it's total bull**** to cripple us with near-GPRS speeds.

Oh, and P.S.- if you've already hit your limit & have ALREADY been throttled... I've never been throttled so I haven't been able to test this on a throttled phone, so I have no idea if this will work to get you back up to speed(nyuk nyuk, I got jokes) but if you do it you won't have to worry about being capped next month.
