[Q] sch-i535 on t-mobile

So here is what I am looking for... i have a Verizon SCH-i535, and what I am looking for is someone who has flashed the stock tmobile rom and changed the bands within the phone its self using the hidden menu (netmonitor app) to see if they can get more than just edge data... I have it flashed to AT&T right now and am using a friends T-mobile sim card that we cut down to fit into the SCH-i535 GS3... it seemed to sync with the towers and get mms.. text.. calls... and internet... just not 3g... I would like to know if someone has found a fix to this issue...
Thanks for your time.

Why not just flash the Verizon Jellybean Rom (Cleanrom or Jellywiz) since global mode was enabled in that Rom? Then drop your tmo sim in.

You know I had not thought about using the global mode on verizon.. I will have to give that a try... do you know if that will allow for 3g on tmobile?

Useful thread so far, but I have a several questions.
I currently have a Verizon Galaxy S3 SGH-i535 with a T-Mobile prepaid sim card (unlimited everything), I can call and text, but cannot get any network access.
I'm currently running Clean Rom 5, settings on Global. Is there any way I can enable data, preferred 3G? [due to that T-Mobile will get 4G on Verizon phones next month).
On CM10, I get Edge and can receive text, but cannot send text. Tried APN settings, etc. Is there a fix for this?
I have tried everything, but no luck. Any suggestions is appreciative

So what I did is i unlocked the bootloader... rooted it... and then flashed the AT&T stock rom on it and then plugged in the TMO sim card and then changed the bands to GSM auto. and it picked up edge... I was able to get access to the network with data... but the only catch was that it was slow as hell... as it was only edge. I am still working on programming to get the i535 on the tmobile bands... thus far I have not been able to get the phone on 4g or even 3g yet... I will keep you updated though.

have you tried using the hidden menu in the dial pad at all??
There is an app out there that will get access to the menu and allow you to change everything in the phone... but be very careful with this app as it can and will brick your phone if you do not know what you are doing with the app..
Netmonitor --> look for this on the google play store
To change the bands to at least get data on the phone, follow the instructions below:
1. install Netmonitor on the S3
2. open the app
3. hit the menu button
4. select field test
5.select UMTS
6. Select DEBUG SCREEN
7. Select PHONE CONTROL
8. Select NETWORK CONTROL
9. select BAND SELECTION
10. Select either AUTOMATIC or GSM Band Preference
* if you choose automatic the phone will look at the sim card and go from there to get the phone on the network to get data on the phone.
11. Select GSM ALL
This is the thread that I am following at the moment to get the phone on HSPA+ or 3G.. If you have anymore questions then please let me know I will do my best to help you out.

I have not tried that yet, but just right now, I got successful on connecting with Data by changing my APN (http://forum.xda-developers.com/showthread.php?p=34632097#post34632097), but fairly still slow G speed. Hoping for HSPA+ or 3G too.

Changing APN's is another way to do what I just told you about... My way is a little easier.. lol .. let me know if you want/need any further help

Hmm, one more thing:
Is there anyway to make this work on CM10 or AOKP? Due to that global setting/APN setting is not available on these ROMs. =/

I have not messed with custom roms just yet I am working with stock roms and rooting and unlocking bootloaders right now... I will see if I can find them time to load a CM10 on my s3 that I am using for development and get back to you with the results here as soon as I have them... I am not for sure if I am going to be able to get to it this week as I have alot going on but I will try and get to it.

Thanks for your support.
In the mean time, I will see if the CM or AOKP team can implement these settings.

that would be great! If I can help in any other way let me know.. or if they have questions please give them a link to this thread. and I will be more than happy to talk to them.

hey guys sorry that it has taken awhile for me to get back to you.. so I flashed the TMO rom on the I5 and got the same results just edge. I think that I am going to try using bobloblaw1 suggestion and flash the verizon leaked jellybean rom and then use global mode to be able to see if I am going to be able to get more than edge...
Here is a guide if you do not know how to flash roms on your S3 here

greetings, all.
i have the same problem that you are describing. running CM 11 Nightly (but problem also existed on VZW stock & CM 10.2). i have read all the forum's about this topic, but as of yet there seems to be no SURE fix to get anything faster than Edge data from T-mobile.

[Q] Looking to update PRL on Sprint...

Looking for a way to update my own PRL running on the Sprint network. I have my MSL and already enabled the other LTE bands so I know that functions correctly. Thanks!

I am wanting to do this as well. Dial codes work but i cant find the one to write the prl. On samsung TW roms its ##DATA## but that dosnt work here. I tied *#*#data#*#* and that shows some menus but none to wright the prl

Seems like I remember seeing that there is a SprintHiddenMenu.apk that ships with the phone. Do you see it in /system/app? Not sure if it will have a PRL update option, but might be worth a look. I'll be using mine on Sprint too, so I'd be interested to know what you find.

I wouldn't be surprised if sprint hasn't had enough of your 00001 prl flashing.

Anyone figure out how to do this? We need diag mode, diag driver and probably a new version of qpst.
Sent from my Nexus 5 using Tapatalk

Definitely still looking...I saw they figured out how to do it with the LG G2 so since this phone is loosely similar I imagine the process should be close. The G2 has to have a diag mode enabled...I really think the key is figuring what dialer code this actually is.

Looking forward to this too. LTE keeps breaking after 30 seconds or so, not that the speeds are any good in Chicago anyway. Can't wait to do some Verizon roaming. Being stuck on Sprint 3g is not ideal.

Yeah but the problem is the LG G2 does not have the same software. This phone isn't only built for Sprint so I have a feeling it will be more difficult.
Sent from my Nexus 5 using Tapatalk

It is built for Sprint. That's why it works on Sprint. It's capable of running on every network short done lte stuff with Verizon. It won't run Verizon as a primary but does roam there. I'm sure there is a way just weather or not you will have to use cdma tool to do it.
Sent from my Nexus 5 using XDA Premium HD app

Has there been any new info on this? My girl is almost about to activate her Nexus 5 (once the sim card arrives). But really need to be able to force roam or at least use 00001 prl.

Bumpity Bump. You guys figured anything out yet? Would love to use the corporate PRL for actual 3G roaming.

Bump :X
Hoping someone finds something soon. I always roam on Verizon at my house but my plan only lets me use 1x... Need dat 3G xD.

Manual PRL Flashing

So I have seen this mentioned in a few threads but I wanted to strart a thread totally dedicated to this...
Sprint and other CDMA provider require a PRL (Preferred Roaming List) to identify which towers to connect to, including towers to roam on. They release various PRLs based on type of account, business or personal. Business accounts generally have more towers set up for VZW and allow users to roam more freely. I'm not looking to abuse this but it definitely helps in situations where I can't get a Sprint signal. Before the Sprint bashing starts, I know the coverage sucks right now.
On many touchwiz Roms I have been able to manually write a PRL file by renaming the PRL file to test.PRL and calling the write PRL function of the dailer by accessing a ## menu and clicking the write PRL button.
I have looked in all of the known dialer codes and menus and can't find a way to flash a PRL manually. Can any developers / hackers figure this one out? I will be glad to help in any way I can and would even be willing to pay a few of bucks for the app if app development is required. Thanks!

I am currently taking a look through the data/data/com.android.provider databaseses to see if I can edit the PRL manually as with how I needed to add the "dun_tether_required" to bypass carrier blocking of Hotspot....

I understand the concept of PRL lists, but why do GSM carriers not use something like this?

It would also be nice to force Verizon roaming. Any one find a way to do this?

This is how I got tethering to work on lollipop. Might be what you need..
$ adb shell settings put global tether_dun_required 0
https://pmf.silvrback.com/fixing-tethering-on-android-kitkat

Just to clarify, I still use the tether fun required 0 entry in Global under settings.db
But originally I was looking for a way to sideload "PRLs"
Initially LTE (4g) was lacking in my area and better 3g (Evdo Rev A) could be obtained based on PRL. But LTE coverage has improved and I no longer need to worry about a PRL to improve 3g performance.
On Sprint I have been using Hangouts Dialer to do simultaneous voice and calling by using data and/or WiFi for phone calls. Allowing me to still browse/use data at the same time.

Have you tried this method?

Cannot get LTE on my AT&T LG G2 only 4G

I'm running 4.4.2 on my LG G2 for AT&T
My wife just got the same phone and her phone shows 4G/LTE Mine shows only 4G
I checked our APN settings for both and they're the same
I checked through the 4636 code through the phone and it shows only the HSPA letters where hers shows up once again with LTE
ANY advice would be great

Try turning data off then on again, it will force it to search for the network.

i tried that one...and i tried the 4646 code and theres no option to change the NETWORK type...this friggin sux...no LTE on this phone and only "4G"...been tryng to figure this one out..
any advice much appreciated.

Maybe replace it?
If this is a new phone that you haven't tampered with, I suggest that you exchange it. New phones don't need any change in settings to connect to LTE out of the box.
Maybe it's a hardware problem. Did this problem just appear out of nowhere? (maybe after the update)?

Like the poster above if its stock return it otherwise reflash to stock to confirm the issue is still there, here's another thread dealing with the same issue http://forum.xda-developers.com/showthread.php?t=2702386

you might be 'ROAMING'
this happens to me. i think theres no att tower near me, i think they use someone elses lte tower, but half of the android phones ive used need roaming enabled to connect to lte in my area. try that it might work.. its in the normal settings app under networks enable all roaming. never had any extra charges. att covers the nation and doesnt count local roaming.
BUT i agree with this guy if my suggestion doesnt work

how to unlock AWS

Sprint note 5 unlock full , is there a way to get tmobile 4glte on this ? I was told that sprint lock that from there phones so I have to enable aws

The Sprint Note 5 variant contains the LTE bands to support Tmobile's B4 and B12 LTE network. If its unlocked you don't have to do anything but just pop in a Tmobile sim card. Not sure what is the confusion is. In addition you have to set your Network mode to be Automatic in Mobile Networks settings.

My note 5 is unlocked by sprint. And i do not get LTE from tmobile, only 3g. When i switch to automatic, it stops working and i get a "!"

Yup but it does have 4glte capabilities, also I was suggested to try verizon but they don't have unlimited plan, at least know I get my clients photos and respond don't have to hang up and all that

I get lte on mine but texts only work on 3g unless I use my google voice number
