On my huawei valiant, i have an icon named '4g hotspot' to one-click activate legal tether....
I no longer use this method- I pay the $5/month now since I use it all the time for work (can't have my internet drop in the middle of something).
While I was still taking it, I found the steps in this thread would screw up my phone if I toggled the app that came on my phone while this hack was active.
I can confirm that various settings toggled will get you free tethering (it'll connect). But without obfuscating your PC data somehow, MPCS will block the connections. If you do this enough times, they just might de-activate your phone from the network. Thats why I whole-heartedly recommend Tor on your phone. It can encrypt ALL your data ON your PHONE.
I'm taking it for granted that your phone is mobile and your PC(s) aren't. I prefer my hotspot to look like a normal router to my PCsthat connect.
I.e. no setup on PC side. Connect. Thats all.
This way, I just grab my phone and go. I have clients. I cannot change their settings. It just makes more sense for me.
Also, I underclock my phone while use as a hotspot. 700mhz is more than enough for a dumb router... lol
I get about 10hrs as hotspot for 3 PCs.
And since I started paying for it, my speeds jumped three fold. I used to top out on BitTorrent PC around 600kbits/s. Now I regularly max around 1.6mbits/s the whole month.
Side note: I am an avid BitTorrent user. I have a 5gig plan and use 15gig/month ish. Before paying for tether, my speed sucked no matter what. I now pay $70/month. I have not seen any speed drop (not caused by lack of signal) since upgrading.
I also have separate wifi @ home. So, 15gig ain't all my bit torrent activities, just when away from faster wifi.
The moment I upgraded my plan, my speed shot up. That was just about 1.5months ago.
I check this thread often, I'll update if my speeds drop back down....
It just might be worth the extra $5/month folks.... Just *might*.
