Question Roaming symbol - Xiaomi Mix Fold 2

My carrier is Rogers (Canada) where I always have the HD (VoLTE) showing in the status bar and beside it the 4G or 5G symbol. When I use my phone in the United States it connects to AT&T as "preferred network", but the HD symbol disappears and although it says 5G, and I can connect to mobile data, I can't make voice calls. If I manually search for networks and choose T-Mobile, it connects and although I still don't get the HD symbol, I can place voice calls successfully. In place of the HD symbol I get either a small "R" above the signal bars, or a large R inside a circle in the status bar. I assume I am placing my voice calls over VoLTE, because all of the American carriers have shut down their 3G networks. Does anybody know why the HD symbol doesn't appear when the roaming symbol does, and also what is the difference between the two types of roaming symbols that I'm getting?

[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.

GPRS without phone service

I'm new to the Windows Mobile platform using GSM and I'm trying to understand the operation of GPRS connection. I have a PPC, HTC TyTn, and I use it to connect to the internet. Most of the time I get a good signal with the antenna and four or five bars next to it. I also get the E or G icon for the GPRS connection. Sometimes when I move into an area I get the antenna symbol with an "!" next to it and the "G" symbol. From my understanding the "!" means no service but I can still connect to the internet. My questions is, due you need phone voice service to get a GPRS connection.
Thanks
E
yes voice is the lowest common denominator
both gprs, edge, 3g, h use the same signals
and voice is the base
Thanks for your reply but I'm still confused. I understand gprs and voice use the same signal but my phone indicates "no service". I can't dial out or receive calls but I can connect to the gprs network and get on the internet. My understanding is "no service" means voice service or the phone could not register on the network. If this is true how can I get gprs service or connectivity .
2 reasons as i see it
1. i'm wrong
2 you are roaming on a network which for some reason only roam data

Simultaneous data and voice

Hi,
My connection is HSDPA(the letter H is shown).
I was trying to access the internet while making a voice call. Sometimes it works, but most of the time the icon changes to G or E and go to suspended!!!
After the voice call ends, it goes back to H!!!
Is anyone having this issue?
That happens to me a lot when I'm in an area with almost no 3G signal. I get the 3G and H with one or two signal bars until a call comes in and it shows E and shows 3 or 4 signal bars. Haven't had these issues inside a major metro area with strong 3G signal.

[Q] Data Roaming Symbol

I have an international D821 model. First time using data roaming in Japan. Enabled data roaming and all is good with surfing etc. However only the "R" symbol is indicated beside the signal strength...no "H", "3G" etc is displayed to show that data roaming is in use..This could lead to high charges incase I forget to turn off data roaming. Any ideas why the data roaming symbol is not displayed? Thanks.

Question Wifi calling icon in notification bar

Do you know how to enable the wifi calling icon in notification bar?
Is there an adb command for that?
I have a US version U1 Ultra and I have 2 providers. a) ATT and b) Freedom (canada).
While the notification icon appears for Freedom in the notification bar and the number 2 is shown (esim), for ATT the phone
does not show any icon. Both wifi calling are active and there is no problem.
I can see the wifi calling only if I go to the dialer and see the wifi calling icon
I have done this experiment with multiple providers and phone (visible, Mint, ATT, Fido, Freedom)
It seems Samsung does not enable the wifi calling for all US companies but it does enable it for all Canadian providers
I don't understand the reason behind that. I do believe having the icon in the notification bar is way
better way to notify the user
I was wondering if there is any adb command to enable the notification for a certain provider
Does it maybe only show for the main sim in use
I'm on tmoble and I don't have a wifi calling icon on my notification bar, only way I know i'm on wifi calling is to pull down the notification panel and see if the network at the bottom says t-mobile wifi calling.
It shows only for me sim2 which is my Canadian provider. I have tried 3 US providers and it never shows any icon. I have to go to the dialer just to see the green call button with the wifi indicator.
It seems Samsung has kept hidden the icon on all US providers for wifi calling
Samsung said all unlocked s22 ultras have the icon disabled for us carriers.
trying to get a answer from tmobile to if ANYONE in the call center has a s22u and has seen this icon is like talking to a brick wall.
the only two options I see for US carriers are to make your call then look at the call screen to see if the wifi calling icon is there ON THE CALL SCREEN or pull the status bar down and look at the bottom of the notification panel.
I have a ticket in with samsung about this being unacceptable and tmobile points the finger at samsung, samsung says since its a branded phone its their fault, so they each want me to go back and forth..
Honestly, my note 9 still works fine and has better battery life. If I could unload this s22 to pay it off at this point I would. The only think I like is dark mode and the camera, the rest of the stuff works better on the note 9 running oreo.
edit - your dial button shows if you're on wifi calling or network calling. it will either be the phone or the wifi calling phone.
I guess thats how they figure people will know. shrug
Samsung unlocked phones do not display the wifi calling or volte icons for US carriers, they never have. The locked versions do.
I don't understand the reason behind that the wifi calling icon is not shown in the notification bar for US providers?
It is really useful to know that you are in wifi mode without pulling down the notification bar or going to the dialer.
Also as mentioned neither the Volte is shown. I know for sure European models show the VoLTE icon on top of the signal
but let's say here in US all or almost all providers are shutting down the 3G networks and VoLTE would be the default so I will not miss it since I know the phone it will be in VoLTE anyways
