[Q] Why doesn't my Roaming Toggle work?

I cannot get my T-Mobile One to stop roaming onto AT&T towers. As a result, the measly 50mb/month I'm alotted goes very quickly. The roaming toggle in mobile data settings literally has no effect at all. AT&T towers are correctly identified in pulldown shade, but data is active regardless of roaming toggle position and T-Mobile is dinging me for it.
History:
HTC One purchased from T-Mobile 4.1.2 with Root - Issue described above was present.
Same handset; EU 4.2.2 Stock rooted ROM - AT&T Towers showed up as T-Mobile in pulldown shade, but data not available regardless of Roaming Toggle position.
Same handset; DEV edition rooted 4.3 ROM and firmware - Original issue is back. AT&T towers are correctly identified in pulldown shade, but data is active regardless of roaming toggle position.
Anyone ever seen this?

The Roaming toggle is for use when you are overseas and then the phone can't see any of your service providers towers
It then can log on to a foreign tower and charge you a large amount of cash for each and every MB
You need to switch of Mobile Date to stop it using 3/4G data
Unless you have failed to state your issue clearly of course
Turning data roaming on or off
Connect to your mobile operator’s partner networks and access data services when
you’re out of your mobile operator’s coverage area.
Using data services while roaming may be costly. Check with your mobile operator
for data roaming rates before you use data roaming.
1. With two fingers, swipe down from the status bar to open Quick settings.
2. If Mobile data is off, tap the Mobile data tile to turn it on.
3. Tap . The Mobile network settings screen opens.
4. Select or clear the Data roaming option.
Select the Data roaming sound option if you’d like HTC One to play a sound so you’ll
know when it’s connecting to a roaming network.

Thanks. I could go on and on about the way the toggle performs on every other handset I've owned, the t-mobile HTC One of a local guy I talked to yesterday, blah blah blah.... As indicated by the HTC doc you referenced yourself, it has everything to do with "partner networks" and nothing to do with their geographic location. Oh, and I want to tear out my own eyeballs when I see "Unless you have failed to state your issue clearly of course" in response to a meticulously crafted post. Then again... it's been a few days since the OP so maybe I'm just butt hurt that no one cares about me :crying:
It occurred to me that I got a new SIM card at the same time I got my One, so I strolled into the local t-mobile store yesterday and had the card replaced. It's a long shot, but I will be in a roaming situation again in a couple days and will update this thread at that time.

New SIM card = no difference.
Swapped SIM with wife's phone. My SIM in her nexus 4 behaved correctly, her's in my One = same problem I had with my SIM.
So, my issue is isolated to the handset.
I don't know why, but I've always thought APN settings were stored on the SIM. I noticed the APN selection on our 2 devices (One LTE capable and one not) didn't change when I swapped the SIMs so I double checked the APN settings on my One. Looks normal to me - LTE works and everything else - but I did some digging and found slightly different settings that owners of unlocked AT&T LTE handsets are successfully using on TMO, so I've applied them and will maybe get lucky when I go roaming tonight.

So what if I'm the only one here?
Anyway, different APN settings changed things BUT not the behavior of the data roaming toggle. RUU'd the phone to TMO 4.1.2 factory new, then upgraded to TMO 4.3 - Same problem.
I finally made the dreaded call to TMO and the tech was actually really good. Much easier to get him to understand the issue than I thought it would be, even though (like everyone else on the planet) he has never seen it.
This issue combined with the better-known low light camera hue problem means I'll receive a replacement handset tomorrow. Will report back here if roaming issue persists with new hardware - if only to vent to myself!

[Q] Data Roaming setting (Off) not retained while Roaming

I hope this is in the proper forum and hopefully the question has not been answered yet. I did a search and have found some threads but not this exact question.
So anyway...I have a Rogers (Canada) HTC One M7 running 4.4.2 and HTC Sense 6.0,
Lately I have been roaming in the USA and have incurred roaming charges even though I set my Data Roaming setting to Off (no check mark). It seems to only happen when I am roaming. Basically this is what happens.
The Data Roaming Setting is set to Off all the time.
I go into the US and lose data connection as I start to roam. This is fine.
If I turn off Mobile Data and then later turn it back on, I get the "You are roaming and incur charges..." pop up box.
The only options are OK or Cancel
Choosing Cancel keeps the Mobile Data Off
Choosing OK turns ON Mobile Data and the Data Roaming setting is suddenly set to ON (there is a check mark where previously there wasn't) and I now incur charges.
Is this by design? Shouldn't the Data Roaming setting stay off, even if you turn on/off the Mobile Data? I am not sure if this is a Phone Issue, and Android issue (OS or corrupted OS) or a Rogers (cell provider) issue or a Roaming (cell provider) issue.
I am hoping someone can enlighten me on this behaviour.
Thanks in advance.

I guess i am having the reverse effect to your problem, my data roaming keeps switching off.
With data roaming enabled, and network selection on automatic. Whenever I am in a no signal area with my home network provider, the phone should automatically roam on a partner network for mobile network and data network. (I can confirm this works when tested on a few Samsung phones). However on my HTC, the mobile network roaming works (calls and text) but data roaming does not work. It connects momentarily then disconnects and stays disconnected and wont re-enable until a reboot. If i manually select a network (either home network or roaming network) and then restart the phone, the mobile data will stay enabled. But as soon as there is a switch between home or roaming network then the data disconnects and cant reconnect until the next reboot.
I was wondering if this could be a hardware limitation or software limitation.

I personally don't think it is a hardware issue, although it may be a software bug and an issue with the roaming provider. I believe that the data roaming setting gets "reset" once the phone mobile data setting is turned back on on a foreign network. I think that the HTC "sees" a foreign network and does not know what to do so it either gets the setting from the roaming provider or just defaults to a set setting.
In my case, I had lots of support calls with Rogers and according to them, my data roaming settings are probably resetting based on the roaming provider when the mobile data setting is turned back on. I actually video recorded what happens and sent it to Rogers when I was roaming. Once they saw it, they told me that any unintentional roaming charges will be credited back.
They did not tell me if it was a software issue or a roaming issue. However, I also tried the same setting using an old iPhone4S and a Samsung Galaxy S3 and both worked fine under the same conditions. That is, the settings were retained.

Exclamation signal icon

T mobile

First of all sorry for my bad English. For those people on T-Mobile network after install elix r v2.0.1 ROM I lose my data connection. So I change the ROM to see if works but still no data working, so decided to restore ( nandroid twrp) and the same results.. So I went to cellular network, then APN and I change the T-Mobile GPRS on APn protocol to ipv4/ipv6 and I got data working.... I know some people already knows this. But people like me (noob) needs some help ..

Good news that it started working! Good follow up by the way. I was about to ask for more information in the OP but it's not needed in this case

I thought I was the only one. I just encounter this issue today
Sent from my Nexus 6 using XDA Free mobile app

I deleted everything on my phone for nothing it was just the APN protocol.I really got pissed

On a side note does anyone know what the exclamation mark is for? I've seen it on both my WiFi and Mobile Data icons.

The exclamation on the signal bars means one of two things.
1. You are not getting a data connection. This may likely be because:
2. Cellular data is disabled.
I just called T-Mobile yesterday (well, two days ago now) to make an ass of myself because I had the exclamation on my signal bars and I wasn't getting data. Turns out I had somehow disabled my cell data. Pull down quicksettings shade, tap the mobile data icon, and check that the cellular data toggle is enabled.
However, I did run in to another issue a few nights before where data was enabled, but I really wasn't getting a data connection. My signal bars were full, and it showed HSPA, even though I usually have LTE in that area. I fixed it by attempting to select a different APN in the list. The APN I selected failed, it automatically went back to T-Mobile, and data came back after that.
Odd, indeed; hasn't happened since.

Ah ok. I only see it now and again to be fair.

WifI and 4g icon showing at the same time

Hello,
I have a teething problem with my P9, more of an annoyance than a problem i suppose.
I added a stock rom to my p9 (EVA-C900B136) to remove the vodafone splashscreen on start up. Since then when I am using WiFi the 4g icon has stayed visible. After checking the data usage, it does not appear to be using Data which is why its not really a problem just an annoyance.
Furthermore, if a turn off data and 4g, the icon remains put. Does anyone have any suggestions on how to stop this?
Many thanks
Rob

This is not a problem. Some of carriers sending the band information -forced- to the device. So this icon showing only; your device and base station using which band for connection.
When you are using the mobile data that icon's label will be Bigger, but when your not this label will be tiny...
I don't have an idea how to remove, but i can say; there are no problem. Only see the label is bigger or lighter.

I think this depends what firmware you are on. When I was on c636b152 my 4G icon always showed when on WiFi. Ever since I was on c432 I never saw that 4G icon on WiFi unless I was sending an MMS or using the Duo app.

4g & wifi sign at the same time.
Hi, yesterday i started to face with this problem for the first time.
I'm on EVA-L09C636B134 never rooted or had an system update. Yesterday suddenly when i restarted my phone, the 4g logo was there near the wifi logo. Even if i close the mobile data, the 4g sign is still there.
Any solutions?

i think i'v surfed all the web but find no solution. :-\

Go into ADB, launch shell and use the following command:
settings put system isShowNetworkType "0"
Restart your phone. You'll now not show the network type while on Wi-Fi.
NOTE: The isShowNetworkType is CaSe SenSitiVE!

See if you have active or not the button from "settings - developer options - mobile data always active".
If it is active, the 4G logo will stay above the wifi logo.

Stuck on verizon 3G, previously had LTE working.

Hello I'm having some issues getting LTE to work on my Nexus 6 running BenzoRom.
I am only able to get 3G, when I previously had LTE working for a very long time. I'm not exactly sure what happened but I tried clearing, dalvik cache, cache, restoring default APN settings, restarting my phone, flashing a new rom, putting in a different sim card (with LTE working) and nothing fixed the issue.
I'm guessing I should just flash stock rom but I'd rather not go through the hassle. I think it might be my APN settings since I vaguely remember messing with it but I restored back to default and LTE still did not show up.
What the heck happened?

Have you gone into the phone menu? If not, *#*#4636#*#* then select phone... And look at my screen shot; at the preferred network type and the turn off volte flag... Yours may say turn on. I reboot after selecting the network and turning on the volte flag
Then in settings/more/cellular networks there should be enhanced 4g/LTE mode, turn that on of it isn't already.
Ya, I'm a dope... Adding the screenshot I referenced.
