Sprint SERO users and phone as modem

I have not read or found anything on this before. So I thought that I would share what I just found. in the support section under sprint power vision it give a tutorial on to use your phone with the phone as modem and it make no mention of a charge for that service. So I asked a online chat rep. they said that it was included with power vision. So I said thanks disconnected started a new session asked again they said that it is not included. So I asked for a number to call they gave me a number for sprint employees as I have the SERO program, and apparently that is considered an employee account.
I called and asked them the same question to the live phone support person. She took a look at a few things and said yeah on the SERO program it is included but not on the power vision. So I asked her If there was anything I needed to do. She said nope I will add it onto your account. I once again verified that it was no charge she said that the SERO plans have it as a option for free but it is not by default turned on.
The number I called is 1-888-503-3078. It was given to me by the send online support person.
I am going to sparingly try it for a few days and then check it out the billing to be sure. I will let all you SERO users know for sure.

Hey i just called and asked the rep the same questions and what she told me was that sero is not covered under the phone as modem deal. She said it would cost 40 dollars a month for it so i decided that it didn't work for me. On the other hand i own the mogul and i asked her if i was unhappy with the performance of my phone because of it having crappy firmware update etc... she said i can call insurance and have them replace my phone with one of my choice for a 50 dollar deductable.

you should try these guys.
you pay a small fee one time till the exp of the license which should last a few years if i remember. just read the details of it. i have used it on sprint network with my treo 650. it works like a charm. you dont need to call sprint to ok this. just as long as you have a data plan on your cell phone. preferably the unlimited one as you will be on there for a while.
http://www.junefabrics.com/pdanet/index.php

personally, i could never get pdanet to work for me so i used usbmodem. after a while, i got lazy and just started using internet connection sharing and bluetooth.
oh yea, no charges for any data whatsoever

I just use Internet Sharing and bluetooth, I'm on the SERO plan, and it works *fantastically*. I get 60Kbps downloads w/out problems and have run VOIP over it.

I couldn't get ICS over bluetooth working correctly, it always drops the connection and shuts down bluetooth on the phone after about a minute, even with the latest ROM. WMWifirouter works great though, I'm getting around megabit/second in places with good coverage.

From primenall's posting in this thread:
There is one edit that should be done, that will eliminate a step in the connection process and will hide your tethering activity. Credit goes to Luv2Chill..... here's the Qoute
""""" OK I've poked into things a bit more and yes it seems Sprint is up to no good in regards to tethering. Those of you running Sprint ROMs should remove the following registry value:
[HKEY_LOCAL_MACHINE\Comm\InternetSharing]
"Extension"="rilphone.dll"
Usual caveats about editing the registry apply here--don't do this unless you know how."""""
Removing means Deleting that entry from the registry, (it doesn't delete rilphone.dll just the shortcut to it when you open I.S.)
Once done tethering is simple using the included Internet Sharing....
USB should only be plugged into PC at this point...
1. Open Internet Sharing and hit connect (it opens a data connection to Sprint)
2. Plug usb into phone, wait a minute for PC to set up and that's it.
Always hit "disconnect" in I.S. BEFORE removing USB, always.

I deleted the regkey and connected via Internet Sharing without issue.
Once you get that working, check out WMWifiRouter. Turn your PPC into a wireless modem/router.

That reg key removal worked just fine for me. Did a small test with it and seems to work just fine. Now the wait until next billing cycle!

keep us updated on the outcome of that bill!!

You should really try WMWifiRouter. The Sprint EVDO network is capable of much more than 60KB/s, but thats about the limit that you can achieve with bluetooth. WiFi on the other hand has much greater bandwidth and won't be a bottleneck like bluetooth. I don't use it much, but I can get around 130KB/s down using WMWifiRouter.

I was wondering... If you have unlimited data plan and setup your phone to act as a modem via the USB connection how can they stop you from using your phone as a modem? Shouldnt we get the full bandwith of Sprints network just doing it that way?

im using that WMWifiRouter thingy, and at first I was doing PAM conneciton (didn't realized it till I knew), then i started getting remote disconnected error. I assume Sprint stopped it on their end. Now I'm using PCS Vision. I really doubt I'm gunna get charged for tethering with the PCS Vision connection, I didnt even do any registry mod/delete.
My question is... Will I get charged for those time I was PAMing? I just wanted to seperate my usage charges to know if I'm getting charged for either both PCS Vision connection and PAM, or just PAM.
I get download speeds of 95 to 150kbps using rapidshare, btw

Sure, if your WM hardware uses BT1.2. If it uses BT2.0, then no
BT2.0 is gonna give you 3mbit/sec on the link, vs .721mb/sec
The 3mbit should be faster then any EVDO network you can find
Power drain should be significantly lower on the phone as well.

t-mobile US USB tethering (not wifi)

Tried getting an answer on t-mobile's forums but it seems mostly people *****ing or having no clue about anything so couldn't get a straight answer and thought someone might know here.
I heard someone say wifi tethering is fine, but if you USB tethering and use more than 100mb they charge an insane per mb fee, does anyone know if that's true?
I just would rather be able to use USB because i've noticed the wifi on it (at least with the t-mobile US rom) is horrible and has issues holding a connection often even when a foot away from the computer connecting and I also noticed while HTC's wifi router is running the phone itself has no internet access and won't download emails, etc which is very annoying, but window mobile's internet sharing tool doesn't have that issue.

I use USB tether on a daily basis, and have been for at least the past six months. I just started using the feature on my Leo, but I've been with T-Mobile for over a year now and been tethering on a MT3G and Nexus One. I'm 100% certain that I've gone waaaay over 100MB, but I have never seen any additional charges on my bill because of data usage.
Edit: Actually, after thinking about it...each Leo ROM is over 100mb soo...

great! thanks, tethering has been my biggest concern switching to t-mobile with them lacking any official tethering plan, I don't mind paying for it if they offered it and did on at&t, just so long as I can do it averaged 4gb on at&t.
now if only the radios on the stock rom weren't so bad, and I'm kind off leary on the whole rom flashing thing.

I wouldn't be too leary on flashing. I was a bit when I first did it with my first phone. But I did a lot of reading, double/tripple checking. With the HD2, I'm just giving it enough bake time so people work out any kinks in flashing first.

id be really interested in how they could tell the difference.

With an unlimited data plan, almost all US carriers kind of turn a blind eye to tethering (or suspected tethering) as long as you stay under the technical data cap (~3-5GB for the US carriers, I think 5GB for TMo).
I've tethered my MT3G with T-Mo for a long time, using nearly 1GB in a day as a wifi router for friends in an apartment, and heard absolutely nothing from TMo.

Well I did try once with my Fuze unsucessfully and worried to try it and brick my HD2 because i've found the instructions i've seen on here not very clear, like I know there was one program it said to flash before flashing rom's but it was only for certain roms and none of the roms seemed to indicate which was the proper way to flash that specific rom :/

Well I know when I had my HTC Fuze on AT&T when I would tether the phone it showed 2 different active data connection, I belive one was called internet and one data, though I don't see that on T-mobile, just have internet so maybe they can't, just kind of want to be sure and not get some crazy bill.

I'm also not worried about a limit or being charged for it, but was hoping for faster connection speed with TMo. Averaging 800kbps 2 days after receiving my HD2, about equal to my omnia with verizon.
Havent readup on it much yet, but is the 7mbps a TMo rarity?
And I too plan on flashing a ROM, trying to wait...

Anyone have a cab to add the USB internet sharing to the menu that pops up when I connect to USB on my computer? It only shows 2 options, and on custom roms it shows internet sharing. Also has anyone found a cab to add the WIFI Router to the Sense Wireless Settings menu? Thanks

I have been tethering for almost 7 years with T-Mobile.
The OP stated 100MB may refer the original web2go thing. The truth is: you'll be upgraded to smartphone data once you go over 100MB, but it's never enforced.
To tether with HD2, you need to use internet sharing in tools sub-menu. T-Mobile Data or Internet doesn't really matter.
It's said there's a 10GB softcap and you're throttled thereafter till the next billing cycle, but I don't hear anybody (including myself) got hit yet.
You can tether, just use it sparingly. It's not your home internet replacement.

When I went into the store an got my HD2 at launch, The sales rep and I were talking about tethering...he said that he tethers all the time on his rooted Nexus and now on his demo HD2 that he was given. He said that he has never run into a problem and has never heard of any customers having an issue with billing. He said that he uses anywhere up to 3-4gigs a month and personally I have never even come close to that. As the quoted poster put it "It's not your home internet replacement" so don't use it as such...
...he did say that they know when you do it though which is a bit concerning...and if you call customer care with a problem concerning tethering, they will not assist you.
...the first rule about tethering, you don't talk about tethering...

lmao!
and I gotta remember my days of 14.4kbps tethering with sprint (tarred and feathered for talking about it back then) and be dang happy with 800kbps!... its stupid FIOS in our home making me think 7mbps is subpar.

I asked Customer care and they were quite helpful. I have the legacy data plan for all windows mobile phones. The plan is 19.99, but is grandfathered into the newer data plans that are going at 34.99. Now, for my plan at least, they told me I have a 10GB bandwidth limit and can use the 3G network as well as tethering is supported. I consider myself absolutely lucky with that data plan. And from what I heard, if you hit your limit, you will be dropped off the 3G network and will run on the EDGE until your limit gets resetted.

Thanks, but I was looking for the Manila Settings Tab - Wireless, where it shows the Wifi Sharing. It's probably cooked in some roms that I used in the past...

I did a search for HD2 tether, and came up with this thread. I don't see my question answered in it though, although I may have missed it, or somewhere else.
My question has nothing to do with whether T-Mobile allows it or not. I have tethered for years on T-Mo (with other phones), with no problem.
My question is simple and basic--How to tether on the HD2?
Since this thread is about USB tethering, my question here could simply be about how to USB tether, although I would also like to find out the best way to Bluetooth tether. (I read something about wi-fi tether in this thread, and have no idea what is meant by that.)
For USB tethering, I assume a driver is needed, for the computer to see the phone connected via USB as a modem. In fact, I probably have an HTC USB driver from previous HTC phones I had, like the MDA (and even the Audiovox SMT5600), but I don't know if there is a newer driver more suited for the HD2. Where does one get the USB modem driver for this phone?
For BT tethering, I think there are two ways-Dial-Up-Networking, and a newer way, I think ICS. I have only used DUN before. I think I might have read that the other way is better though. Is there a thread I missed, with a guide to BT tethering with the HD2?
Thank you for your input.

And it has indeed replaced my home internet. Pings suck for games, but other than that, it's completely serviceable.
The way if was explained to me by TMO folks, is you essentially have an uncapped bandwidth limit. However, once they see you hit 5gigs for the month, they will throttle you down somewhat.

As far as tethering goes, TMO is probably one of the friendliest towards it in the US. Just don't call into 611 asking for support or how to tether, they wont throw you under the bus and start billing you extra, but they just don't officially support it, you might get a rep in a good mood and willing to help though
I've been tethering for at least 6 years on TMO, started with a seirra wireless GPRS aircard then upgraded to an EDGE card. I would swap my SIM out of my phone when using the card. technically not tethering i guess, but then I got a Samsung phone that supported bluetooth and always tethered with it to my laptop and winmobile PDA

will i be able to share 3g (since no 4g in boston until 4th quarter)

i have been reading about this 30 dollars extra a month to share my 4g connection with laptop, computer and anything that uses wifi...but my questions is, will i have to pay the 30 to share my 3g connetion since boston will not have 4g until 4th quarter 2010??? i currently have a touch pro 2 stock sprint and run xdi wifi sharing on it and anything can pick it up. since the evo is android, will there be a program that i can run out the box to share my wifi? please elaborate as far as the internet sharing abilities of the phone...

PDANet, and once it is rooted you will have more options...free options.
I certainly wouldnt pay the 30 for wifi hotspot... you can get it for less using other software....but its up to you..ya know

Yeah there are a bunch of options once the Evo is rooted, which hopefully will come soon before most people have a chance at it (this is why i think Google gave them out at the developer conference). But the $30 a month is not worth it. wait then root it and have it for free.

i've played with it in google i/o and u can enable tethering even on 3g, now the wifi was so freaking congested there i didn't get the chance to try connecting to it, but chances are good that it works

Still need the $30 plan.

darn it...i guess i will just wait for the phone to be rooted to get a free wifi sharing program. at least the 3g will be unlimited to tether unlike 3g now where they only give you 5gb...(even tho it didnt matter on my touch pro 2 under xda wifi sharing) because it went in as internet usage! lol

I'm more hopeful that once the phone is rooted we will able to use the included wifi hotpsot program without paying the $30.mo. I betcha the hotpost program now sends out something at loin and only ESns with that permission can use it. Every Sprint Windows Mobile and Palm phone I've had in the past could be hacked so that the built in tethering app worked without the need to upgrade my account

isnt the wifi hotspot program the same as allowing other devices to connect to your phone via wifi? is so, when its rooter there will be a program allowing u to do this..unless sprint completely and uterly somehow with alien technology blocked it on teh phone.

Yes there are other programs but from what I've seen the built in program is truly built into the software including an on/off widget.

tethering and router - Tethering Now Possible

please make making a tethering app and wifi router a first priority in for the wp7... developers
MOD EDIT: Tethering instructions at post 11 onwards

The chances of this happening without 3rd party socket support is extremely low if not impossible. Until Microsoft allows sockets tethering will have to come from Microsoft themselves.

i though that that the phone would be capable , but that there would be no support or apps unless the cell service requested

That rumor turned out to be false. At launch WP7 will not tether but I'm sure we will see an update within the next couple of months that will add it. Since updates come from Microsoft directly I don't think carriers can block it.

I wouldn't say that carriers can't block it. If you look at the iPhone, it was blocked in the carrier settings on the phone.

Also, the carriers has a way detect you are using the phone as tethering or web-browsing, if your data plan doesn't include tethering, the tethering feature means nothing.

Doing some research to upgrade from my dumb ass x10 (was my in between phone) and found on Optus Australia site that Omnia 7 can be used as a tether, so I'm guessing that they are not blocking it.
But hey who knows till I get this next week bundled with an Xbox Kinect - woot.

There's a 99% chance that the site is wrong. WP7 does not support tethering of any kind right now.

I tether occasionally with my ATT Tilt running WM6.5.
I am about to receive my Focus this week, and I am confident that there will be the ability to tether this phone soon. History is on my side. In the meantime, I will pop my sim card into the Tilt if I need to tether.
The iPhone was a locked OS at first, the jailbreaks came soon, as did tethering.
As far as ATT being able to detect when it tethers, I doubt it.
In the past, the theory was they could detect the user agent string for the web browser as "not a mobile browser" but since the WP7 browser is a full browser, I see it as a simple matter for the tethering app to replace the user agent string on the fly, so the data stream appears to be for the bundled browser and not a desktop browser. Your laptop will browser will give you a normal experience on each page.
ATT has a money clamp on the data usage anyway, so I doubt they really care that much since as you would hit the 5 GB limit of the laptop tethering plan, you would have paid $65 ($25 for 2GB+$10 for 1GB+$10 for 1GB+$10 for 1GB). They have lost nothing.

Awesome news, if it works. Can anyone who has tested this confirm that it's working and also if you are still able to use the phone to receive texts/calls/etc? Thanks, and good find!

Can someone who's done this post the usb drivers that get downloaded? I'm running on windows server 2008 R2 and suspect that it's not pulling them down because of this. I switched the phone to tethering mode, but when it connects and tries to add the driver it doesn't pull anything down.

T-mobile Blocking all forms of Tethering.

I was just using PDANet on my friend's laptop and I got two texts from T-Mobile saying the following: "Free T-Mobile Msg: Phone Tethering & Wi-Fi Sharing access has been blocked. Please add a Phone Tethering & Wi-Fi Sharing plan available at my.t-mobile.com"
Now I ignored it until the browser sent me to a signup page. I've tried WiFi Tether, Bluetooth, and Barnacle and it blocks each one. Anyone else get this?

Not just you.

That would suck. Would this apply to USB tethering as well, or just WiFi?

PDANet IS usb tethering.
:O
oh... and someone at the Vibrant forums is having the same issue... which is why I'm here.
:X

I am tethering from my G2 (USB tether) to post this message. It works fine, though TMO might be rolling this block out.
Edit: I am posting this via Wifi tether, so that seems to be working for me currently.

I just checked PDANet and WiFi hotspot and they both worked, so I guess they're "rolling" this out.
Makes me wonder...some of us never got the OTA rollout. I wonder if perhaps I'll never get this rollout either.

I think they can affect PDANet and Easytether since they are market apps. Wireless Tether for Android and Wired Tether for Android aren't market apps so im pretty sure those are beyond T-Mobile's grip.

Might have something to do with the G2 not being rooted and trying to tether. I think after its rooted it should work without a problem. At least thats what a tmo rep told me.

When I read all this on the xda app, i went ahead and hooked up to wifi tether. thats how i'm writing this msg. I am rooted and do have the largest plan tmo offers which includes the unlimited data. idk. we shall see. oh yea, no tmo msg as of yet.

I'm unrooted and used wifi tether this morning for 3 hours with no problems. I just don't understand how they can detect us using it.

There are various techniques they could use to do this; if we know exactly what they're doing, we can probably bypass it.
Probably one of the simplest techniques would be user agent sniffing; if they see desktop user agents from the same device, they'd know something funky was going on.
I'd be interested to know whether the OP can work around this situation by changing his user agent string on his desktop browser. I'd also be interested to know whether the phone browser continues to work properly even after he's been caught, and if so, whether changing the user agent string on the phone causes it to report the block message as well.
Another test for whether they're sniffing user agents is to try to make an ssl connection instead of http from the desktop browser. Assuming that the phone browser still works, SSL on the desktop browser should also still work, if all they're doing is user agent sniffing.

In an HD2 thread one guy was saying that he was downloaded a movie to his phone, but wasn't tethering when he got the text. Perhaps they're determining by the amount of data used in a specific amount of time. If that's the case it supports the theory of TMO seeing all data as data.

That's actually good, then. If they're using such a naive detection method, it's sure to result in a ton of false positives from people legitimately using a lot of data with their phones, and consumer complaints should result in them disabling it before too long.

If this works like any of T-Mobile's other services then they prorate the add-ons so you can add it when you need it, then cancel it when you don't and you would only pay a fraction of that $15. I do this with the hotspot feature all the time - enable it for a trip when I'll spend a lot of time in a hotel (or airports, etc.) where they offer wireless and then cancel it at the end of the trip and I pay less than a single day of wifi at a major hotel.
(disclosure - I snatched this post off the T-mobile.com forum but I was going to say the same thing!)
I need to confirm this "add it when you need it". Not good for everybody but for those of us that need tethering a few times a month it's not so bad, 50 cents for one day. Tried via the chat on T-Mobile.com to confirm this but they are useless!

When I first applied the OTA and started playing with the built in tethering, I noticed some log entries from DataConnectionTracker whenever I turned tethering on or off. When I enabled temp root with Visionary and tried using the stand alone Wireless and Wired tether for root apps, these entries did not appear.
I haven't had time to play with it much, but it might be useful to run logcat with a filter for only DataConnectionTracker activity while trying a variety of tethering techniques under root and non-root circumstances.
Of course the experience reported by the HD2 user does not line up with this theory, but there may be multiple things going on. If T-Mo really is blocking based on data volume, it will completely blow up on them as people start intentionally doing data intensive things without tethering.

I sure as hell hope they don't do this to the grandfathered plans... cause if they do, I'm gonna go on a *****-storm.
Edit: I'm tethering on the WiFi hotspot app and I didn't get any notice. Everything is as it has been since I've had this app. If not, I have Wireless Tether for Root Users. I refuse to pay $15 extra bucks a month when I paid for an unlimited plan a couple of years back.
