[REQ] Can I stop data when roaming?

Hi all,
I know this is probably a strange request and so I'll have to give a bit of background. Recently I changed my mobile provider to 3. 3 have their own telephone coverage in certain areas and if you are outside those areas you go on roaming with Telstra. The issue is 3 charges huge $$ when roaming on Telstras network for data (voice and SMS is fine).
My question is that my TP obviously knows when I'm roaming as it displays the service provider as 'Roaming'. Is there a program that will stop my data (and only data) use when I change over to the 'Roaming' service and activate again when I am in the 3 network?
Thanks for you help!

Hi, another aussie 3 user here...
I agree with the TS as this is one of the major problem we as 3mobile user face, is there any kind soul out there that could help us with this as my knowledge on PDA is limited.. Thanks for any1 who is willing to help in advance.

With the Sprint TP, I can go to
Settings>Phone>Services>Roaming
and set an option called "Data roam guard" that allows me to choose whether or not data connections will be allowed while roaming. I'm not sure if this option is available for you, but give it a try.

I myself would like to have an automated function for this. Until then I will have to manually switch to my dummy data connection.

Normally it doesn't connect on roaming.
and if it will, it asks first.
isn't this the case with you?

I have an app called NoData
Works really well and lets you enable/disable any data connections

I know about the NoData. However, you still have to enable/disable data connection manually. I'd like to have it automatically disabled when I am roaming.
For example my IM client (QIP) does not ask me whether it should connect or not. So it is very easy to have an "accident" with data connection :-(

I'm another Three user in Australia, looking for something like this as well. I often use my phone while on a tram and it might switch from 3G to Roaming while I'm browsing the web. I'd like for it to warn me so I don't download heaps while roaming (I think it's $1.65 per MB or something crazy like that).

Hi, another 3 Australia user here...and yes, I've been waiting on this sort of function for years now.
Part of the problem here is that 3's "roaming" is not actual roaming in the traditional sense. Normally, the phone detects a roaming signal when on a foreign network and displays a roaming indicator (looks like a little triangle) at the top of the screen. You'll find this is the case if you ever take your phone overseas and use International Roaming. Telstra's network does not give you this signal, and hence even the few roaming aware apps we have (e.g. pocket outlook) don't detect when you're on Telstra's network and turn off their automatic schedules.
The best way I could think of to do this automatically is with an app that detects either Telstra's network ID values (the phone detects these and translates them to the text "Roaming" at the top right of today, much as it translates the real value "3Telstra" to plain old "3" - 3 and Telstra share the 2100MHz network in a joint venture, much as Vodafone and Optus share theirs...you will see the real value if ever you use a non-3 rom) or the network connection type and then runs that NoData app (I haven't seen that before...credit to the guy who posted it).
I've often though some sort of even responder app would be useful. Something like Gyrator, except that read network status instead of physical hardware status. Anyone know of anything like this?
Then you could set up something like:
* On detect EDGE/GSM switch off data connections
* On detect HSDPA/3G switch on data connections
OR
* On detect network ID of Telstra's GSM network switch off data
* On detect network ID of 3's/Telstra's 2100MHz 3G network switch on data

Look at phoneAlarm.

My HTC TP says 'H' up the top when I'm in 3 coverage and 'E' when I'm roaming. Just near the top it says '3' when I'm in a Three area or 'Roaming' when I'm not...
Don't you have the same phone? What does yours say?

I think that perhaps paying 15+ pounds (around AU$40) just to switch off a data connection is a bit steep...any other suggestions around?

My point exactly. You will not see the real roaming indicator in Australia as you never actually roam here. While three call it "roaming" when your phone is on Telstra, the way they have set it up prevents the phone from knowing this is the case so the few roaming aware programs will not be able to adjust for it.
The phone shows G/E when on Telstra as Telstra provide a GSM/EDGE network. It shows 3G/H when on Three's network as Three are providing a 3G/HSDPA network. Hence, you can work out if you're roaming by looking at this even though it's not actually a roaming indicator.
If you look at your home screen though you will see either a "3" in the top right corner of the clock or "Roaming". That's what I was talking about before. It's not a roaming indicator either; it simply shows the network name (with a translation applied from the actual network ID in this case).

thanks caeci11ius, I'm glad you could explain this is better detail then my original statement. I am presuming that this form of roaming and charge to customers is quite rare.

You wanted a program which can automatically switch band when roaming.
This is the only program I know which can do that.

This is Exactly What I need Also. I have looked everywhere? I Dont believe anyone else has come across this issue before and has written something to fix it.
Need a program to detect when the Phone is in 3 or H area (displayed at top) and disable DATA ONLY when G or E is displayed. My work around at the moment is to select HSDPA only connection but this makes the Voice Calls dropout whenever I cannot recieve Three's Network. Can anyone help. There is many people who would be in this same boat.

[Q] Carrier network auto-select does not work

Hi everyone,
I'm new to Android on Polaris, and while I substantially succeeded in having a good-working system (incubus rls16 + radio 1.59) I still have some minor problems.
One of the biggest is that auto-switching between carriers doesn't seem to work. I'm on Three-IT, and usually this carrier relies on roaming carrier TIM where it has no coverage of its own. Now I find that when I leave Three coverage, the telephone "sticks" with the last cell information (e.g., it goes on displaying previous signal strength, the one it had under Three) and does not perform any carrier auto-switch.
This results in an unreliable strength status: I see good coverage where in fact I have none, and have to manually check for my default roaming operator.
Switching to "plane mode" and back always does the trick, as it forces radio to perform a new search while re-enabling.
Does someone of you have some advice to solve this annoying problem?
Thanks in advance!

[Q] No data transfer on UMTS

Hello all,
Been using this phone for ~6 weeks now.
Familiar with all 3G/H and no network issues - been there, done that...
Yet, I find it odd that while my phone is sometimes steady on UMTS, it has no actual data connection (Ping fails and also other tools), while calls can be carried out!
Also, at times, while network signal is showing as working, I'm actually w/o network connection (phone calls) at all.
And last, in several occurrences a day, while I'm not in a call and probably also not in 2G (I restricted my connection to WCDMA only), I get Network signal yet no data signal in the notification bar (WIFI is off).
I tried re-flashing 1.78 EU RUU (for my unbranded phone) with no change.
I tried rooting and putting Lee's ROM with no change.
I switched microsim from my provider with no change.
Is my only solution is sending it back to HTC for repair? or there is another solution to that frustrating (!!!) situation?
Many thanks for any response!

Seem to have lost 3G data after factory reset (4.1.2)

I've been running a flashed 'official' 4.1.2 (Singaporean origin ROM?) for over a year now but recently have been experiencing performace niggles. Therefore I decided to do a 'factory data reset' from the settings menu to clean the tab up. It was never actually wiped before as even when I went direct from 3.2 to 4.1.2, all the applications were kept in place, so I figured it could do with a good internal flushing.
After reinstalling my apps, everything is indeed running smoother and with no real performance complaints. However, I seem to have lost my ability to use the inbuilt 3G modem for data. It still registers with the network provider as per the SIM card (in this case, o2 UK) and I can send txt messages to the number so it really is on the network and working to some degree.
Despite this, I don't have a network connection via 3G nor do the indicators of network data connectivity show on the bottom status line irrespective of whether nor not I enable 'Mobile Data' (i.e. I can't see the little 3G/HSDPA indicator or the up/down arrows). All I see is the reception strength indicator, whichever way I set 'Mobile Data'.
WiFi is still fine (subject to the 2.4GHz only restriction of the ROM).
Anyone have any ideas what I should do?

Just to follow up - the problem was more basic than an issue with the tablet hardware or flashed OS. It was an APN configuration issue. Basically the auto installed APNs were wrong and I had to manually configure a suitable APN for my pre pay mobile broadband.

Is it solved? Please update main title to SOLVED

[SOLVED] 3G consumes more battery than LTE, how this happens?

Hello XDA Community!
When my new phone (Huawei P9 Lite Mini) is on 3G/2G auto network mode, it consumes more battery than LTE/3G/2G auto mode even mobile data off.
I do not understand how this happens? For example, while 3G consumption at overnight is %10-15; LTE is only %2-3. This problem is the same in daytime too. Mobile data is off, unneccesary services/apps disabled, and no extra application installed while this happens. I tried all "wipe/factory reset/update firmware/factory reset/wipe/no app install" procedures, enabling all battery saving options, but it did not work. This is a problem for me when I'm in non-LTE areas.
This problem occurs the same result in different locations. There was no problem with my previous phone and I use same nano sim card.
I tried the following but it did not work:
- Wipe cache, factory reset, wipe cache,
- Wipe data/factory reset over recovery menu,
- Update latest firmware, wipe data etc. again.
How this happens and where am I doing wrong? Thank you for your help, best regards!
EDIT: PROBLEM SOLVED!
I changed my mobile carrier (provider) and the problem is gone. This is very interesting! I worked for hours and days to solve the problem, but this problem is neither caused by the phone nor by the software...

WCDMA (aka 3G with support for 2G/Edge) is in always-on mode on most phones, because that's how you receive and emit phone calls and, for most phones, SMS (in some more recent phones, LTE takes care of sending and receiving SMS/MMS), so if you're in an area where 3G/2G reception is poor, your phone has trouble locking on a cell with enough power to maintain contact, hence the battery drain.
4G/LTE only works for data, and voice if you have VoLTE (Voice over LTE) enabled, but works on a on-demand mode, even with cellular data constantly enabled. In other words, the 4G modem on your phone will memorize the latest position and IP address the nearest 4G tower/cell allocated it, and connect to it using the memorized settings when you need it to.
Not so with 3G, where DHCP doesn't exist, at least not the way it does in 4G: it uses PPP (Point-to-Point Protocol), where an ad-hoc IP address is attributed to each new connection, based on a pool of existing addresses allocated to the tower and its owner (carrier) by the authorities.

Thank you for your reply!
When I googled about 3G vs. LTE battery consumption, everyone says that LTE will consume more batteries. That's make sense on first thought. So what I've been through is very interesting to me.
I think about is there a problem with my phone's 3G antenna. (footnote: I don't know about that 3g and LTE antennas are same or seperate?)
But I understand that you say this is normal, right?
Edit: I found a forum that this problem may be due to the operator (carrier). I'm still investigating...

3G and 4G operate on basically the same principle: receiving and sending "information" via radio waves.
The difference lies in the frequencies each standard uses, the way the data sent over them is modulated and demodulated, and how handsets make and maintain connection, so if you stay in the same location, and set your phone to 3G-only, then switch Airplane mode on then off, it'll take your phone longer to reconnect to the 3G cell/tower with the strongest signal (not necessarily the closest to you), because it'll have to go through the whole getting-acquainted process again, whereas in 4G, it'll go straight to the "Hey, how do you do? Long time, no see".
Now, if your phone antenna has a problem, you could be standing a few feet from the tower, in line of sight, and still get a crappy to non-existent signal. How many bars are showing on your screen is just an indication of how well your phone is receiving the signal from the tower; it doesn't mean that this signal is consistent and steady, hence the bars coming and going in real time.
If I were you, I'd download and install the Hidden Settings app from the Play Store, and run it; there, you go to RadioInfo, and you'll get a lot of information about how your phone modem actually works. It's a bit technical, but it would give you an indication.

I will try and looking for a new carrier. Thank you again. See you.
