Found a potential data unthrottle solution!!?!

First, a little bit about me that lead to how I came across this...
I work in the electronics department of a retail store, and when the days get slow I like to tether my G2 to the wifi enabled tv's and watch netflix with coworkers. I do this on almost a daily basis and burns through A LOT of data.
Of course after a few days I get the text message from T-Mobile after I get through my 5GB of (fake) unlimited data and will be slowed for the remainder of this billing cycle... This normally results in my downstream speeds going to a trickle of 7kb/s as apposed to my uncapped speeds of anywhere from 300kb/s to 1400kb/s.
So I have another job that I work on the days off sometimes and it's running deliveries. I use the navigation app to get to where ever it may be for work and sometimes my GPS doesn't like to locate me right away. When this happens at work, I start to panic (I don't know my way around town for sh*t) and try every solution on hand I can think of. I tried fixing permissions then network operator selections and eventually the GPS will locate me function just fine.
So I have never hit my cap while working my part time job doing deliveries, and have never really used the navigation app until I started working there and this is how I came across this uncapping of my data while trying to fix my gps, I went into wireless & network settings, then mobile networks, and select network operators, it does some searching for a bit then gives me the option for AT&T or T-Mobile, (I always just do select automatically) and after doing this, my data speeds return to normal... like I am still getting downloads at 600kb/s+.
According to the T-mobile "my account" app, I am at 7.26GB for this month.
(I will upload screens in a second for the naysayers)
Something about this network operator selection thing has the ability to unthrottle me everytime I go over my data. Not sure what actually happens behind the screens when I do this method but just thought I'd share in hopes that it may provide some help to others in a possible loop hole to the (fake) unlimited data issue a lot of us run into.
P.S. Noticed that the speedtest app always thinks I'm in Dallas TX every time I do the network operator unthrottle thing, when I actually live in the Chicago IL area.

Wow, this seems like a great find. finally we can maintain full speed over the month. Gonna definitely give this a try once my speed gets throttled. Thanks!

Just for safe measures before people start saying it's not working, I'd like to just make it known that I am currently running on CyanogenMod-7.1.0-RC1-vision and using 2.6.35.13-UmaroV1.06+ kernel. Radio-26.03.02.26_M. Dunno if that affects anything in this department lol.
Also one thing I've noticed and forgot to mention...If I connect to a wifi network, once I have disconnected from it, my speeds are throttled again but doing the operator selection unthrottles it. This is the only thing I've noticed that reactivates the throttle but is still fixed in a matter of minutes.

Ill test this once I finish download battlefield 3 though I dont think Ill hit 5gb once done. Probably need another 1GB or so.

BTW to save data from navigating, you can enable a feature in Google Maps 'labs' to allow caching map data. After enabling it, long press on a location and tell it to cache, it'll then download a 10 square mile radius of that point and save it to your SDcard (you can cache multiple areas). Then it won't cost you data next time you load that map
Anyways, interesting find! I wonder if its because it kinda... re-registers your phone on the network, and you get a new address / spot on the network? Idk... I've only hit my 5gb once and I wasn't capped so I can't really check this often.

My guess is that Tmobile servers learned your usage statistic including your location, amount of data consumed, most connected APNs nearby and usage schedule. They then use those factors to throttle/filter the APN you are connected to the most. But once you "refresh" the apn list or the cache on your phone by searching for network operators, your phone is no longer "blacklisted"
But that is just my theory.

Yes, I'm on T-Mobile. But I'm on CM7 like you are, and CM7 already includes the app. Is downloading it from the market the only way to get it to work?

I just downloaded it from market. Don't think it was there when I installed CM7.

Yeah, we known about this for a while. Same thing happens when you switch apns (wap.voicestream.com for example). It just changes your ip on the network and will last for several hours or until you reboot. Its temporary but works good enough. Too bad my old one doesn't work anymore. Its all controlled server side now.

In the build.prop in /system, with any text editor, you just need to change this:
ro.product.model=HTC Vision
ro.product.brand=vision (or whatever it says here)
to this:
ro.product.model=T-Mobile G2
ro.product.brand=tmobile
That's it. Reboot and it'll work just fine. I change it every time I update ROMs on CM.

The way I understood this: Once Throttled simply navigate to network operator settings and select your standard operator or reset your apn settings and you will at least for a certain limited time have unthrottled data?
At least as far as Berlin, Germany, network operator O2 goes: I cannot confirm that this actually works. (HTC Desire Z, latest Bulletproof MIUI rom).

Mine works on CM7 without editing build.prop about 90% of the time. Kinda weird people seem to have different results.

That's what I've been doing and it works great. Might just be a loop in the T-Mobile networks but I thought I'd share in case it wasn't brought to anyone's attention

Just to be sure I went for the latest nightly and tried again.
Made sure that I got new ip's. But still nothing. I guess that o2 germany simply handles throttling differently.
Thanks for sharing though, would've been nice if it worked.

This didnt work for me. Im using MIUI Bulletproof ROM.
Although, right around the same time this thread was made, I went over the cap and still had full data speeds. It lasted 4-5 days I think.
I hit around 6.5 GB before I was finally throttled and that was around the end of Oct/beginning of Nov.

Mobile network not working - please help (Nexus 4)

I basically suffered the same issue for my first 2 days with a new Nexus 4. I discussed my issues in the Straight Talk thread (ST). After I exhausted all the possible solutions offered up via my Google searches, only then I went the route of contacting Straight Talk directly. I could have saved myself a boat load of grief, if I had simply contacted ST at the start. Give it a try. I went to the Facebook icon on the ST homepage. Then, I clicked the Support icon on the ST Facebook page. It asked about creating a Ticket. I said yes and entered a short description of the problem. There were a couple of email exchanges and finally about 12 hours after starting my communication with ST, they said to pull the battery and send myself a picture message. Of course, we cannot pull the battery, so I just sent myself a picture message. A miracle. As I sent the message, the phone internet/data connection opened and my first MMS was finally sent. Note, I checked my mobile data connection just prior to sending the MMS message and it was still "disconnected". I think ST must have done something from their end, to correct my problem. I only used the exact APN settings that were provided with the ST AT&T sim card activation kit. Save yourself some trouble and open a trouble ticket. I learned the hard way. I love my N4 and my ST AT&T signal strength and reliability is great in the NJ, DE, PA tri-state area.

Thank You for the info, I called ST and they said my ported number is not in their system yet(even though i can use the number), which will take 24 hours and then may be the data services will work. I have couple of more hours to verify

Rooting cannot break your phone's ability to access the network.

Any new info on this OP? I just got my N4 yesterday and am using a AT&T Straight Talk SIM, but I also can not connect to mobile data. I had my number ported over from Boost Mobile, so did waiting a day or two help?
EDIT: I also tried a million different APN settings to no avail.

Custom rom or a weird sim card I'm pretty sure. Mine says tmobile but you can change it with custom roms. I vaguely recall seeing this before and it was with the sim carrier.

Wouldn't be a custom ROM. Phone came straight from Google and I'm the first owner. Will check with sim provider and see if its that.

ok so this appears to be a phone related problem. as nexus obviously takes a micro sim i tried it with an adapter in an old n95 and after that in a mates galaxy s3 and they register on "EE" both on the home screen and when you search for a new network.
however mine still appears as in the first picture and as below searching for a network. so the nexus either isnt setup for ee/orange/tmob or it cant read the sim????
this is running the latest 4.2.2 jellybean and has made no difference even restoring the phone to factory once.
anyone else using a nexus 4 on ee/orange/t-mobile in the uk and got this problem?

Ive also contacted orange (my provider) and it was them who suggested trying in another mobile but they also ran a diagnostic and that didnt bring up any errors.
have i got a dodgy sim card? (seems unlikely as it works fine in other mobiles)
has the nexus 4 not been configured properly for my network? (also unlikely as there must be thousands of people with a nexus 4 and on the same network)
Or has the phone got a fault itself? (bloody well hope not as its only 4 days old!!)
anyone shed any light on this as its got me really confused

looks like you dont have a mobile data connection. since you dont have a mobile data connection, maybe it cant send the right data to your device, hense the @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@.

I doubt it since I'm on GiffGaff where you have to manually enter the APN settings but it always said giffgaff wherever it had the carrier label. Also, as you can see the other networks' names come up fine. @OP maybe you could try manually entering the APNs and connecting to mobile data to see if simms is right.

Mine is exactly the same. I'm on orange. My SGS2 showed it as EE like it should be. This nexus 4 has always had varying strings of the '@' symbol. Been like that since I got it in November. I just tell people I'm on an exclusive network not available to paupers.

I have the same issue, I got a panther orange sim and put it into the nexus 4 and 'Orange' was displayed for about 4 days. Then out of the blue it changed to @@@@@@@.
I reset the phone but nothing changed. I took out the sim card and with no sim in the phone, I searched for mobile networks and the phone lists Orange, EE and T-Mobile. But with the sim in the phone they are all listed as @@@@@@@@.
Sim works fine in every way as far as I can tell, its just the network name which is displayed incorrectly.

I took my Note 4 and a hammer into the garden today...........

I took my SM N910L Note 4 and a hammer into the garden today because no matter what I've tried
(and I've tried everything http://forum.xda-developers.com/note-4/general/im-bonkers-ill-pay-50-dollars-to-fix-t3169748)
I just can't get it to work. I put the Note 4 on the grass and I raised the hammer above my head - but I just couldn't do it....... it's not the money......it's the waste.............
So, I'm upping my offer. If you can tell me what to do to get my NOTE 4 receiving and sending DATA again (basically connecting to my carrier) I'll send you 100 dollars. The first person to to show/tell me something that allows me to make a skype call or receive even 1 email through my DATA connection gets the money. INSTANTLY!!!!!
Please read the thread above, all the info is in there except this. I have been trying to flash a different custom ROM in the hope that that will fix it but none of the ROMs I have downloaded will flash thru TWRP (even though I can backup and restore thru TWRP). I get an error message saying unable o open zip. Anyway, if anyone has any ideas please post.
A very big thank you again to all those who have tried to help me already.
I have a hundred dollars pinned on the wall in front of me .................. I'll be sooooooo happy to see it go !
P.S. I know that you are not helping me just for the money, I know you are helping just to help me out (and I have had so much help already), but I just want to make it worth your while too.

Is it the modem? Perhaps try installing the official docomo 4.4.4 rom for the note 4 via Odin. See if that fixes it?
I'm a noob but it's all I can think of. I hope it helps somewhat and if not then just return the phone?

I think it is the modem too, but I've re-installed 4.4.4 and 5.01 many many times. I flashed individual modems too. Nothing seems to sort it out. Can't return the phone - bought on Amazon from Korea, seller sucks, Amazon unhelpful, that's a dead end - I need to fix it.
Thanks anyway (I'm a noob too )

Might sound stupid, but have you tried a different SIM card?

load stock rom on it for the 910L with all stock CSC, do a complete reset, turn off carrier data in settings, select carrier network manually then turn on wifi carrier data bluetooth. make sure smart network switch is off. disconnect wifi and try it out.
and if that doesnt work ship me the phone instead of using a hammer on it lol.

Have you called your carrier to make sure it's not some sort of problem with how they have your account set up?

Yup I have 2 sim cards now with two different carriers and have spent hours and hours on the phone with them both trying to work out why it is not getting data. My only glimmer of hope is that although they are different carriers I have found out that they both use the same network (dohhh) so maybe it is specific to that network - DOCOMO.
thanks for your help.

If yes, you probably have some sort of APN issue with Docomo. If not, you may be boned.
IF YES:
Go to Settings -> More Networks -> Mobile networks -> Access Point Names
Press the plus symbol on the top right, set the name to DOCOMO, set the APN to mopera.net, set the MCC to 440 and MNC to 10.
If this doesn't work, use 0120.mopera.ne.jp as your APN instead.
If that still doesn't work, have you tried a b-mobile SIM? I had this issue once when I was in Japan for some time - Docomo doesn't like people using unlocked, imported devices on their networks for some reason.

Talked to Samsung Japan today. They wont fix try to fix it even if I offer to pay - has to go back to Korea. The company I bought it from said it is user negligence, Amazon says it was working for 7 weeks so it is not there problem.
So, seems I'm left with a very pretty, extremely useful Samsung iPod. No phone though.........................

Seriously considering saying yes
At this point I'd consider human sacrifices, voodoo dolls, or crystals too.

Are you sure that SM 910L is your local Note 4 variant? There might be hardware differences in different variants that only accepts certain signal bandwidth for a specific carrier.

Nexus 6p no longer works on verizon after using with vodaphone sim card on a trip

Hi all,
My 6p that used to work great on verizon can now no longer make or receive voice calls, even though 4G data works!
I have been using my 6p on a verizon prepaid plan for months, and it has worked flawlessly. I popped a sim into an S4 to activate, then put the sim in the 6p, and everything worked great.
I recently went out of the US for a week. Verizon prepaid doesn't work at all in Europe, so I bought a tourist SIM with some data to be able to use my phone while traveling. Again, this worked great.
When I got home, I put my old verizon sim back in my 6p, expecting to go right back to where I left off. The problem is that can't make or receive any voice calls on the 6p. Whenever I try to make a call, I get a verizon message asking me to enter the 10-digit number again. Incoming calls are going right to voicemail. SMS works fine though, and 4G LTE works fine -- just no voice.
Verizon tech support is no help. They say that if I use the device on anything other than verizon's network, it has been flashed and will never work again fully on the verizon network, which is obviously BS.
I have tried putting the sim card back in an old S4, and voice calls work fine there, so I know it's something with the 6P.
Any ideas on a setting that I might need to change on the 6P to make it work again? The Vodaphone person took my phone for a second and may have made a change or two that I didn't see to the settings? :/
Any help is appreciated! I use this phone for work, and if I can't get this resolved soon then I guess I'll just have to switch to tmobile ASAP.

I recently went out of the US for a week. Verizon prepaid doesn't work at all in Europe, so I bought a tourist SIM with some data to be able to use my phone while traveling. Again, this worked great.
When I got home, I put my old verizon sim back in my 6p, expecting to go right back to where I left off. The problem is that can't make or receive any voice calls on the 6p. Whenever I try to make a call, I get a verizon message asking me to enter the 10-digit number again. Incoming calls are going right to voicemail. SMS works fine though, and 4G LTE works fine -- just no voice.
Verizon tech support is no help. They say that if I use the device on anything other than verizon's network, it has been flashed and will never work again fully on the verizon network, which is obviously BS.
I have tried putting the sim card back in an old S4, and voice calls work fine there, so I know it's something with the 6P.
Any ideas on a setting that I might need to change on the 6P to make it work again? The Vodaphone person took my phone for a second and may have made a change or two that I didn't see to the settings? :/
Any help is appreciated! I use this phone for work, and if I can't get this resolved soon then I guess I'll just have to switch to tmobile ASAP.

Same as yours, unfortunately. Should there be another verizon APN for voice?

Dial *#*#4636#*#* and see if your settings match mine in this screen shot.

The format is a little different. I have Verizon Wireless as the current network, but Voice Service says:emergency calls only. Voice Network Type is Unknown.

I'm on Verizon and Every time I use a project fi sim in my Nexus and then go back to the verizon sim...the verizon sim doesn't work any more. I have to get a new sim every time. I think it's just the way Verizon does sim card management on their phones.

Thats where your problems at. At the bottom mine says LTE/CDMA auto prl does yours say the same? If not you need to change it. If that doesn't help you can hit the 3 dot menu on the top right and click on band 6. It's possible your network band was changed. I had this problem after mistakenly changing mine to USA band.

I actually went to verizon and got a new sim and still no luck. Verizon is crazy. I'm about to just switch carriers.

I changed it to LTE/CDMA, but it couldn't find any service at all under that option.
On the three dot menu, weirdly I only have US, Cellular 800, PCS, and Class 10 (800mhz secondary), but no class 6.

It sounds to me like your radio bands were modified. You can try flashing your radio again in fast boot or install a custom ROM like chroma that has a lot of extra bands to choose from. A while back I saw a thread in this section where someone had made a zip you can flash for this same problem also.

I had a similar problem with Sprint. Text and data worked fine but no calls. Might be a CDMA related problem.
Mine was caused by me changing the band the "USA" in the phone info (*#*#4636#*#*) menu. I had no way of getting it back because whatever ROM I flashed I never had the "Auto" band option. The Vodafone guy may have changed your phone's banding to Europe and for some reason it's a pain to change it back. I ended up complaining to Google and they allowed me to RMA the device.
However, I saw this thread later which may help fix your problem. Flash the ROM from that thread and go to the info menu and click "Auto".
Good luck.
Edit: Found another thread here describing the same or similar problem and the above fix worked.

I started having the same problem today, with my wife's 6P and my daughters 5X, it turns out the HD Voice feature from Verizon was my problem, since that was the only thing I had modify before they lost phone call capabilities, I went back to the Verizon website and under "My Products and Apps" you are able to disable or remove that feature, I then rebooted each phone and they are able to make calls again. Hope this helps someone.

Sorry to bump an old thread... I've run into this exact same issue. I've tried the rom in the post above - had lots of errors of services stopping but eventually managed to set it to automatic... nothing helped. I tried another purenexus 6.0 rom and while that works better as far as rom goes, it still doesn't let me place voice data calls.
The only thing that halfway works is enabling HD voice - and VoLTE on the phone. This means I can make phones when and where I have LTE but still nothing over the normal cellular voice network.
Anyone find any way of fixing this?
