Disabling roaming overall.

I just got a new FUZE and I'm already annoyed with an issue I'm having:
Halfway on the way home my phone kicks over to my neighbors to the north - Robbers Wireless. I live fairly close to the Canadian border and my FUZE seems to like Robbers more than it does the Deathstar, leading to roaming charges up the... you know.
Is there any way of disabling roaming of any kind, be it voice or data, preferably automatically? People suggest NoData.cab, but that is no good to me - I'll not notice myself hit the Rogers towers until the last second - hitting Home and seeing "Rogers Wireless" in my upper left corner. My phone never alerted me to data roaming yet it kept a data connection open the entire drive home and hopped to Rogers.
I kept trying to select networks from Start > Settings > Phone but it kept locking onto Rogers and didn't offer me a choice of AT&T at all.

Have you tried choosing your network manually instead of automatic?

Doesn't give me a choice if I'm looking where I should be.
Start > Settings > Phone > Network shows only 2 things:
"Current Network: AT&T"
and a [Find Network] button. No network selection or anything was offered to me.

Call AT&T and tell them to disable international roaming.

[Q] How do I prevent Samsung Galaxy S 4G from connecting to AT&T?

I have Samsung Galaxy S 4G with T-Mobile in San Francisco.
Whenever I go to an area without T-Mobile signal, the phone connects to AT&T. I called T-Mobile and they said that's because T-Mobile has roaming agreement with AT&T so my phone would connect.
The problem is, when my phone connects to AT&T, I can't make any calls. It says the phone's not registered. T-mobile says that's because I'm in an area that has T-Mobile coverage.
You'd think that the phone would be smart enough to figure out that only emergency calls can be made (which is what BlackBerry does and shows SOS sign). The real problem for me is that, I have WiFi calling enabled with cellular preference, and when I'm in the basement of my office building where there is no T-Mobile signal (but there is WiFi signal), my phone thinks it has cellular signal so it doesn't activate WiFi calling, yet no phone calls are coming in b/c it's not registered to AT&T's cellular network.
Is there a way for me to force my phone to only connect to T-Mobile? I know there isn't on the regular settings menu, but perhaps experts could tell me how to do so using those star-sharp keys listed here (http://forum.xda-developers.com/showthread.php?t=842134)?
Thank you!

Set wifi preferred instead of cellular.

Unfortunately, that doesn't work for me because I move around a lot, and Android WiFi calling feature doesn't have handover.
There's got to be a way to prevent this phone from connecting to AT&T at a low level somehow, no?

How do I do that? Have checked the manual but can't find location where explains how to select wi-fi preferred instead of cellular. Your kind advise will be appreciated

Open WiFi Calling and select settings. You'll see Preference. Select Cellular Preferred.

I think in setting then wireless and network, then mobile networks then network operators click the default settings.... select manual and wait for the carrier to pop up.
Will this solve your problem?

yep manual is exactly what OP should do.

if the settings for network operators are set to manual then u select the network u want and it sticks unless u manually select a different network provider. u are in select automatically mode so the phone can switch all on its own. this should solve your problem as other people have already mentioned

I have tried this many times and works as long you don't turn the phone off. After I forced the phone to manually select T-Mobile I checked many times the default setting and it remained in manual until the phone was turned off. When I switched it back on it was again in automatic mode and switching to ATT when signal is low.
Is there a way to prevent this? If not, well , first thing when phone is on in the morning is to check default setting.
5/24 I finally gave up and sold the phone. Samsung says they have not received any claims regarding this issue eventhough you see it frequently in the forums. I returned back to my HTC HD2 and will wait for the G2.

[Q] how to select network operator manually?

i am using AT&T's Samsung galaxy s2 skyrocket (unlocked), i am unable to select a network operator manually. As i keep going around different countries, i keep on purchasing local sim cards for calling home, so i need to select the network manually, otherwise it will select the network which has best signal strength and i may land up paying heavy charges for roaming.
when i go to wireless and network/ mobile networks/ network operators only thing which comes written is "DEFAULT SETUP" and that is greyed out. (when i tap on nothing happens).
also when i change back to my old AT&T sim, i am able to access that greyed out area, but when i put another sim "DEFAULT SETUP" is again inaccessible.
can someone please guide me through it..??

Are you using the stock ROM?

I have bought the phone just a weak ago... i have changed nothing except for SIM card....
actually i dont know any thing about ROMs and i m new to android also... i just guess that above written satisfies your question.

well thats your answer. You can not do that on stock att firmware

what modifications i have to do .... to achieve the desired results...??
and please tell HOW to do also....!!

You need to flush custom ROM that supports changing network operator settings.
Look at this post if you would like to use custom ROM:

SM-G920W8 | No Option To Connect to LTE

I bought an Unlocked Canadian S6 recently, and it just won't let me connect to the LTE network.
Model Numer : SM-G920W8
Android Version : 5.0.2
Baseband : G920W8VLU1AOCG
Connecting to the LTE is not even an option. When I go in the Network Options, I get the choice between :
-WDCMA/GSM (auto connect)
- WDCMA only
- GSM only
I know for a fact that I am in the coverage zone, so no need to ask that silly question
I've tried different SIM cards, played in the options a bit, and factory reset the phone about 5 times now, yet nothing seems to work.
Also, when I try to do the update, it just reboots and gives me an Android logo and a failed Icon
I've only seen one other post like this from a carrier's support website, but no solutions were found.
**Update : For a reason, after a recovery, it will connect to the LTE for a bit or until next boot, then go back to what it is now.

First question, who did you buy the phone from? Second, Is it second hand? By default, Wind mobile does not allow the LTE option to be displayed in system settings as they as a carrier don't have LTE. It is blocked by the CSC setting for the carrier. As for other carriers It should leave you the option to connect in settings where you say it is not. If it is a Wind phone, You would need to change the CSC to enable the LTE selection. There is a method to force LTE even without option in settings, but I think it is removed in the latest firmware. Try dialing *#2263# in the dialer. It may bring you to menu that will allow you to select LTE. This is not a permanent method though as it will need to be done every boot. The other way, (If you are in fact a Wind/Mobilicity phone) is to enter dialer and enter *#272*IMEI# with IMEI being your devices unique code. If at all possible, take a full nand and Titanium Backup before doing this and be sure to transfer everything off the phone to a PC. This method wipes everything and I mean everything off the phone buy is a surefire way to enable LTE.

Yes, it was second hand. I didn't ask who was his carrier simply because it was unlocked.
I'll try it tomorrow, thanks for the information

Here is the menu you will see when you type the *#272*imei# code into your dialer. The codes are the carrier names. Mine which is GLW is Wind, BMC is Bell, RWC is Rogers, etc.

Maybe there is no LTE in your area...

It would still be visible in the Settings/Mobile Networks/Network Mode menu which it is not. His problem is more than that.

Sweet! It works :good: Thanks man
Now, would you have any ideas on why the update won't work? I didn't get much into it yet, but I will soon.

I'm not sure why it wouldn't update, but now that you have changed the CSC you can download the update and flash with Odin. Pick your carrier and go to town. The guy running the following thread runs his own firmware host. He's got amazing DL speeds. Usually takes me 6 or so minutes to do the 1.6gb file. http://forum.xda-developers.com/showthread.php?t=3086387

I'm having the same issue.

Connected with someone selling a G920W8 version. LTE is disabled and the codes aren't working. Can you reaffirm which unlock code worked for you? I'm on Fido, what LTE network are you using?

hi BCSC
Thanks for the details. I searched complete net and read all articles but nothing set me up with the proper thing. i read your solution i dialled *#2263# and all i got is service mode and in that i went to band selection , LTE and the all ....... Yes and its showing LTE in mobile data. THanks so much.
But now another issue, network is showing perfect but no outgoing and incoming calls.
in incoming its showing busy and on outgoing its not connecting to another phone.
And, Lte is not showing in mobile networks, There only 3 options still are showing.
Mine is same Wind S6 but i had to use in India.
Let Me know
Thanks once again
Cheeerzzzzz
Varun

Picking LTE from the service mode will note make it visible from the settings menu. Its more of a workarpund instead of a way of permanently enabling it. As for the issue of no out/in calls, my best guess is that it could be due to which LTE bands are being used or are available in India. Unfortunatly I have no way to test that option. I only was successful in getting the Wind LTE option on Canadian carriers.

G920R7 GSM Unlock..... Feel like I'm close....

I'm on PD1 6.0.1 with a G920R7 nTelos. I rooted using CF-Auto root, flashed TWRP for the g920p, and installed the zip file from this thread... http://forum.xda-developers.com/showthread.php?t=2394689
After that I installed Phone INFO ★Samsung★ and used it to access the hidden menus. Went to the 2263 menu and set all band preferences to all and selected the LTE/GSM mode only, then went to the 4636 menu and set the radio to GSM/LTE (prl) auto. I've tried GSM only and it switches back to GSM/LTE (prl) auto on its own.
I now have access to a mess of options in the network mode selection screen in settings, and setting it to GSM only and 3g only still does not allow me to catch signal. In network operators it shows AT&T, yet if you try to manually select the network it never goes through. *#0011# still shows it switching through LTE bands and not staying on one or registering on the network. In the device info screen (4636 menu) it shows the correct phone number and AT&T for current network, but under cellinfo still shows it switching between LTE bands and under GSM disconnects it shows ======DATA======.
At this point I'm not quite sure what to try next. Please let me know if anyone has any ideas to try. Thank you.
EDIT: I've also tried the G920P domestic unlock and G920R4 unlock with a box, but no luck with either as expected.

i can do remotely if u want

I have a box but the device isn't supported, it's not locked I must just be missing something. Anyway you could private message me what I'm missing? I've been through all the settings messing with it and all, even flashed the CDMA to GSM zip floating around here. I know I'm missing something silly. Any help would be appreciated and I don't mind sending you a donation provided I can do this myself next time.

I just messaged him on Hangouts. I don't know if its something he can help with or not because I believe we have the same box and the g900r7 isn't supported. This isn't even answered on that Voldemort website.

Did you figure this one out? I'm also interested in GSM unlocking this phone.
Messing around with it I was able to get an ATT Sim card to pull 3g data but no call/text or lte.
