[Q] US GSM Carrier Unlocked Sprint Touch Pro 2 - Data Issue

I unlocked my Sprint Touch Pro 2 and I am using an AT&T SIM card here in the United States successfully.
The first few times I used GSM mode, a menu would pop up and ask me which network settings I wanted to use (AT&T or T-Mobile).
Now, that menu is no longer popping up. So, I am unable to select the settings for AT&T. Data is now not working on GSM (the phone tries to dial #777 as if it is connected to Sprint).
How can I get that dialog box to pop back up and prompt me to pick the carrier settings? I'm assuming that is what will fix it.
Thanks for the help.

well, I got it working by manually defining the following parameters in a new gprs network connection:
Access Point Name wap.cingular
Username [email protected]
Password CINGULAR1
it works, but then when I go back to CDMA on Sprint, it tries to use this connection.
Is there an autoconfig program that I don't know about? It popped up on my screen when I first started switching between CDMA and GSM, but it hasn't come up again.....
How do I enable "auto-switching?" More importantly, why won't it just get this info from the AT&T SIM card? Why do I have to enter it for it to work now, when I didn't have to a few days ago?

Do you mind share the information how you unlocked your sprint pro2 (CDMA I assume)? I have same phone and want to use it in GSM oversea. Sprint customer Service told me it is not a global phone. can't unlock.
thanks in advance!

[Q] How to enable LTE by updating PRL settings, using a Rogers LTE s2 on Fido LTE?

I just purchased a used Galaxy S2 SGH-I727R skyrocket that was originally purchased from Rogers in Canada a year ago by the original owner. The phone was completely stock with stock Rogers firmware, most up to date version 4.0.4. The phone box shows LTE DUAL BAND 700MHz/AWS as the capable signal bands on this phone. I'm not sure if any of these are blocked on the Rogers custom firmware.
I unlocked the phone and tried to use it on Fido LTE network, which works on the same network as Rogers as it is part of the same parent company now. However, my phone will not pick up the LTE signal, no matter what. The SIM is brand new from Fido on their new LTE network that I got just 2 weeks ago. The SIM is properly provisioned for LTE as after installing sim in the phone, the apn settings window automatically populates with FIDO LTE settings (ltemobile.apn and ltedata.apn for tethering). I also have a full LTE and 4g data plan.
As LTE would not connect, I entered fido's regular 4g/3g settings as a separate apn and the phone connected right away to the 4G network (with very good speeds, DL up to 11MBps and uploads up to 2-3 MBps). I'm in the downtown Mississauga area right beside toronto and this area is fully covered with LTE. I tried using the 'data roaming' option to see if there was any difference, I tried to manually select fido in the 'network operators' section etc but playing around with these options generated zero success.
I looked up forums on Fido where even though this phone is not in their line up of supported devices, their helpdesk suggested that any Canadian LTE phone with proper fido lte data plan and proper lte sim should work on LTE. I even drove around in areas near my house where I've seen a friend use Fido's LTE signal on his Fido htc one device, but no success on my phone.
***Some people have activated proper LTE signal on their Google Nexus 4 American phones for use in Canada by dialing *#*#4636#*#* and then going into the following menu's 'phone information' section to select LTE or a different PRL option with LTE. I tried to do the same thing but when I enter this hidden menu's 'phone information' section, my screen blanks out, phone becomes unresponsive and after a minute or 2 I get a message that some android system file was closed etc. I tried de-activating the data connection and tried to enter the same menu option but same end result. I thought maybe rooting the phone will give me access to this menu but even after successful root, my phone blanks out when entering that 'phone information' menu.
Can anyone suggest something or help me figure this out please. I have a feeling the PRL or LTE option needs to be selected manually here and I need to access that menu. Since FIDO LTE network on Rogers existing LTE network was activated a year later, there may be some updates needed in this area (as the phone was originally set up for Rogers LTE from a year ago).
OR, should I just call FIDO support, and assuming they help me with a non-fido phone, try to get this sorted out with their techs?
Thanks

weird when you say the box says "aws", rogers doesnt support aws as far as i know, wind uses aws, i cant find my box to check
did you perferm a factory reset, which modem are you on
EDIT: phone does support aws, but cant see why it would state it on the box if its from rogers

Because the LTE networks are running on AWS and in some cases 2600 MHz frequencies by the big providers in Canada. Even thourgh only Wind/mobilicity use the new AWS for their regular 3G/4G networks, the LTE with Rogers/Bell/Telus is on AWS while their regular non-lte signals are still on their standard gsm bands.

k, but did you check which modem you are on
did you perform a reset.
u stated you entered this, *#*#4636#*#* you should of not received errors(but i tested on jb)
try this for band preference *#2263#
try a working rogers lte sim card and see what happens
are the fido apns the same as rogers
try the rogers apns, used to work for the 3g when i was on fido but that was b4 they offered lte
last resort but maybe your best option, flash stock w/odin, howto in my sig

Thanks again for your help. I realized later on that I got the non-LTE sim card from Fido, so I went back yesterday and got an LTE sim card and had it activated. However, I can never get LTE even though a person sitting beside me on her Rogers S3 with the exact same apn (as I realized rogers and Fido have the exact apn's for LTE network, ltemobile.apn) is getting LTE. I know Fido is the value brand, so they get secondary priority on LTE, which is ok but I realized the problem below:
WHEN I had the non-LTE sim and even with the LTE sim now, one option has never worked. In the mobile network screen, I'm supposed to have just the Ltemobile.apn (Fido and Rogers LTE) radion button selected and Ltedata.apn (for tether) as the default options. These are also built into the rogers stock rom and this phone is originally a rogers a phone. My friend's S3 has the same 2 apn's listed while she's connected to rogers LTE (her's is micro sim, I couldn't try it on mine). With these options, I CAN'T connect to ANY data network at all. I can only do calls, no data. I tried doing batter reset, restarts, change the LTE/HSPA and HSPA etc settings, no luck. The ONLY time I get data is when I manually enter the non-LTE apn settings as a separate apn (Fido-core-appl1.apn) and it connects to 4G. The speeds were good earlier but since changing to the LTE sim, the same 4G keeps disconnecting or it gives much much lower speeds.
As per your suggestion, I followed your thread to re-install the stock rogers ICS rom with odin. Even after that, no change at all. I tried using the *#2263# option to change LTE band to 7 or auto, but no luck as this phone's hardware is only for 700 MHZ or AWS, of which rogers uses the 2100 on pretty much all their devices. At this point, I don't know what to do. I've followed everything from Fido site with LTE phone, LTE apn, LTE sim and LTE data plan, but the phone doesn't even recognize the ltemobile.apn unless I enter the regular Fido apn.
Should I change the radio/modem on this phone to something else or try the JB roms? Do you think that may make a difference, or is this something else, where LTE apn is not even recognized for data. Someone please help, my first phone upgrade after 2.5 yrs has been a complete buzz kill lol.

theres is a method when using *#2263# in picking the lte settings, ill search for the posts as i cant remember the exact details
if you lived or work near me i could test it out for you, bolton or toronto near yorkdale, since its a second hand phone you cant rule out hw failure, but you would need to test it out with a rogers lte sim card.
did you try manually searching for available networks from mobile settings
edit:k i found it, its old and uses the rogers older apn, try with that one or whatever fido phones uses now which i think would be the "ltemobile" apn, if already set then just goto the "power off" phone part
-.go to settings/more/mobile networks/access point names
Now click bottom left haptic button followed by Add apn

Thanks Vincom. If there is a HW problem, that would really suck but it's hard to see that would be the case if everything else is working fine, inlcluding 4G. And it would be great to know how that band selection process works, as I don't wont to select the wrong option and be stuck with a non-working radio.
I'll give Fido tech support a call and see if they can figure this out, but it's unlikely unless there is something wrong with my plan (LTE plan not activated, unlikely).
Let's say even if I were to have to check the phone (driving to Yorkdale area is no big deal), what would you test on this anyway?
Thanks

Actually let me try out the options you later added in your post above

Thank you, it worked!

Thank you x 1,000,000 Sir, I owe you big time. I've spent last 3 days non-stop on this phone while my wife has been complaining I haven't left my phone since I got it. Now I can go home today and spend more time with her lol.
Here's how it worked: I just copied the ltemobile.apn default settings into a new apn, which I saved with a different name (so that I could keep the original default settings saved separately). As soon as I saved the new apn settings (did not enter anything in the 'apn type' field) and wala, LTE came on. For some reason, even with the same settings exact default settings, it wasn't recognizing the saved apn but the newly created one was picked up right away. Tried the speed test in square one area at work, 21Mbps down, 12Mbps up, wow (coming from my old 3G phone, this is amazing).
I didn't even have to go through the rest of the process with band selection etc., as this is a Rogers phone on their network, so those settings should'nt be changed anyway.
Thanks again. I think I saw some posts on fido forums with other people complaining about stuck with 4G on non-fido phones. I'll update those forums as well.
Happy new year to all

I just make a new son ltemobile.apn and it sticks even on reboots

[Q] Samsung Gravity Smart troubles

Hey all
First of All i'm not thoses kind of people who post question without searching and reading, i already did it, so maybe i didn't search enough or didn't get what was explained, so the less that you can do is to give me link who explain my problem.
So how everything start:
My brother got a new phone "Samsung Galaxy Q", but trouble began when he tryed to connect on 3G network. It's Always connect on "E" (Edge) when mine (Samsung galaxy mini GT-s5570) connect on 3G and then on "H"So here's the first trouble.
I tryed the " *#*#4636#*#* " and make it in "WCDMA only" nothing is happening, when i try " *#2263# and make it to "WCDMA All" network disapear, even if i try other wcdma frequency. so it refuse wcdma at all.
So i started to search and planned to flash with the original stock ROM.
But here apaear a new problem: when i searched the firmware on samfirware.com i whrited "SGH-T589R" as it was apearing on the starting screen of the phone (With Fibo). I saw that there was another version of this phone "Samsung gravity smart" (SGH-T589) wich is apearing on samfirmware with T-mobile, so i just wanted to check what's this phone and typed the name on google Images. And maybe it's not a great discovery, but the phone that i've got, have "T-Mobile" writing on top of the phone when Samsung logo is on the bottom, but it's not the case with "samsung galaxy Q". So i was a but confused. The "menu/back/search" keys are visible and white with gravity smart but not with galaxy Q.
The phone that i've got looks like "samsung gravity Smart" (T-mobile on top, and 'menu/back/search" keys whith and visible) but when it's booting it shows "Samsung galaxy Q sgh-t589r". So i decided to download the "samsung gravity smart" firmware and install it.
I already did that with the "sgh-t589r" with Odin firmware and it done successfully, but when i tryed to install the "T-Mobile" firmware with Odin, flashing finish correctly, but when it comes to the Boot screen (Samsung gravity smart exclusivly for Tmobile) it sucks there and nothing is happening
So here's the problems, and now my questions are:
- Do i need to change stock firmware to 'T-mobile' one and leave "Fibo"'s one?
- Is the 3G network trouble (always on E even if i make the right APN settings) comming from stock firmware?
- The Android version is Froyo 2.2, do i have to update it to fix this?

I have a answer for the first question in that you should go to the fibo one as that booted fine for you and is most likely the firmware for your phone. But it might have screwed your phone up when you flash the t-mobile firmware because you never should flash firmware not meant for your phone it might hard brick it. Try flashing with Odin back to the fibo one and if it doesn't work you might have bricked your phone.

Thanks WidlfireDEV, i'm back on Fibo firmware since T-Mobile one blocked on Screen boot when i tryed it, But 3G network is still sucking (Always on "E"), it's my main problem.
So Could anyone help me with that?

If it is not fibo try adding the apns for your carrier. Then it might work properly.

So, the forum is my last chance.

Are you sure that the phone in question has the right bands to handle 3G from your carrier maybe your phone although it could be a 3G phone doesn't have the required bands to have 3G from your carrier and therefore can only get edge.

Here's what i found when i wanted to see my "Samsung gravity smart" specification in phonearena website:
GSM : 850, 900, 1800, 1900 MHz
UMTS: 1700/2100 MHz
Data : HSDPA 3.6 Mbit/s, UMTS, EDGE
Global Roaming : Yes
I tryed to change 3G settings using code *#*#4636#*#*, and there are 5 GSM/UMTS band available when i select "select Band"
Euro Band (doesn't work when i choose it, no transmission)
USA Band (idem)
Japan Band (failed)
AUS Band (doesnt work)
AUS2 Band( dosent work)
it only work when i make it to "Automatic"
I tryed also the *#2263# code, and choosed in the "WCDMA Band preference", "Wcdma all" after that, the "E" disapear to let no network at all, making me to come back to automatic or gsm band.

Ithink I know where comes troubles from:
when i dial *#06# it shown "000000..." as IMEI number, and when i used Root explorer i didn't find /efs folder.
I didn't know that it exist so, i'm not sure i'm the one who deletet it with flash or it was already erased with the "fake" rom installed on it.
Anyway, here's the fact: i've an smartphone with no "EFS" folder, with "0000000..." as IMEI number, and i read somwhere that this folder not only containt IMEI number's files, but also some important files who may have relation with 3G network.
Now i've to look for a solution to my new problem.

Unlocked Z3 D6616. No data on AT&T Help!

I just bought a Z3 D6616 off of eBay that was listed as "Unlocked". To me unlocked means that it will work on other networks, so I did not worry that I was going to use the phone on AT&T. I got the phone today and took it down to get a NanoSim for it (my old phone used a MicroSim). The guy at the AT&T set it up and got the sim installed, and the phone can receive calls, but it has no data service at all. I mean none!. I looking through every article I can find online and they all say that the D6166 is locked to T-Mobile and cannot be configured to receive data on the AT&T network.
Is this true? I really like this phone. Is there any hope of fixing this problem? Please!

Check you APN info.
Settings > more > mobile networks > Access point names
Then press the plus sign and enter the details for your carrier. That was how I got mine working.
You mentioned AT&T, I'm going to guess in America and a quick google search gave me these details

Thanks, but I tried that first thing and it did not work. I spent hours on the phone with AT&T and they gave me all the settings over the phone and it did nothing. Do you have the Z3 model D6616 or the D6603? The D6603 can be used with AT&T, but so far I have found no way to get the D6616 to work and nobody else that has either.

I have the international D6616 version with an unlocked bootloader. Changing the apn was what worked for mine. I am connecting to a German provider, so maybe it is an At&t issue.

It's very possible that the area you are in does not have the supported ATT LTE band that is compatible with your phone. Since the D6616 was designed for T-mobile, it will only have Bands 2, 4, and 12. ATT's primary LTE data band is Band 17, and that is not supported by your phone. ATT also supports band 2, 4, and 5 as well, but there is a good chance that those bands are not in your area by ATT

[Completed] Help! Tmobile Samsung S7 locked only on 1800 mhz band. Already rooted

Hi everyone.
Last time i was in xda forums was when i try to mod my windows mobile CE 5.0 lol
This is my sad story:
I bought in the US a samsung s7 with T-Mobile SM-G930T, i paid a guy who 'unlocked' it in there. After that i brought it to Colombia, in here i run the T-mobile unlock app which succeded and erased itself after that. Then the cellphone started working with all the mobile companies in my country except for one that operates over 1800 mhz, other companies do work fine. When i insert a simcard of this company it just says that 'Not registered in network' and wont do nothing. I already tried to put the APN settings correctly (Actually it automatically loaded every company settings detected).
After that i tried to root with a modded Odin with a custom ROM and it succeeded and i got the SuperSU application, tho the cellphone its a little laggy now, but neither that way it worked. Anyone knows how where should i start looking?
I went to this company support and they sent me to Samsung support, which redirected me back to this company, lol
Thanks in advance guys

Then the cellphone started working with all the mobile companies in my country except for one that operates over 1800 mhz, other companies do work fine. When i insert a simcard of this company it just says that 'Not registered in network' and wont do nothing. I already tried to put the APN settings correctly (Actually it automatically loaded every company settings detected).
After that i tried to root with a modded Odin with a custom ROM and it succeeded and i got the SuperSU application, tho the cellphone its a little laggy now, but neither that way it worked. Anyone knows how where should i start looking?
I went to this company support and they sent me to Samsung support, which redirected me back to this company, lol
Thanks in advance guys

Hi,
It seems your phone is region locked due to which you are locked onto a particular mhz network frequency...
yes the first step would be to try to a custom rom to see if this over rides this situation or you could try below situation below... this is ideally for s6.... or atlast google search...

Ok, since now we have root, many users wanted to know if they can lock onto certain LTE frequency bands using Samsung's ServiceMode. So here is a quick guide.
ServiceMode is Samsung's proprietary Engineering Mode, built within the TouchWiz framework, readily available on International variants, and some domestic like T-Mobile. It allows us to observe the RF connection, change certain RF related settings, and lock our phones onto specific technologies and frequencies. Sadly, Verizon has been blocking user access to Engineering Mode for years now.
So in order to enable access to ServiceMode on Verizon GS6/Edge you'll need to:
- Download Root Explorer
- Navigate to /efs/carrier/HiddenMenu
- Use TextEdit to open it (not text viewer)
- Change the value to ON (upper case), Save and Exit
- Restart the phone
Once restarted you can dial:
*#0011# to observe the connection
If you want to lock your device onto a specific LTE band (13, 4, 2):
*#27663368378#
- UE Settings & Info
- Settings
- Protocol
- NAS
- Network Control
- Band Selection
- LTE Band Selection
Here you can force your phone onto a specific Verizon LTE Band (13, 4, 2), or use LTE ALL if you have VoLTE (Advanced Calling) enabled as this will eliminate the need for CDMA radios.
To go back to default, go through the same process but at Band Selection make sure to chose AUTOMATIC.
There are a lot more settings here, you can enable AMR WB on UMTS if you use T-Mobile so you can get HD Voice on their UMTS layer, etc... Carrier Aggregation has already been enabled, so no need to tweak that.
If you aren't sure what certain settings and values correspond to, it's better to avoid tinkering. You're responsible for your own actions.
