It's relatively easy to disable data roaming on an Android device in the "Wireless & networks" settings section, but the phone still tries to connect to other services via roaming like voice and SMS. Is there a way to disable ALL roaming whatsoever? I know about airplane mode, but that completely disables all connectivity, and it's also annoying to have to remember to keep turning airplane mode off and on again when I enter/leave the vicinity of this network. I'd like to be able to connect to my network but not allow any roaming.
Why disable? Becuase the network offering the roaming isn't one I trust, as I think it may be intercepting and recording my data. So I don't want my phone to use it.
It seems Windows Mobile has a relatively straightforward to do this by selecting "Don't roam". If Android doesn't have any option to do this (no, not Airplane mode - that disables ALL comms!), then that is a rather annoying lack of a feature!
This might not be the answer you are looking for but your operator should provide some means to prevent roaming completely; your phone then would not be able to access any other network for any service apart from emergency call.
Anyone knows the settings for using WI-FI for downloads at home instead of the cell network?
you simply turn on Wifi, and give it your network password so it can connect, and as long as it is connected to WiFi it should not use the cellular network other than to notify you of texts or incoming calls
Hi to all, i have a question about architecture of android OS, and i would have an answer before i start develop my custom android OS.
I would like to know wich "component" of android OS take decision about which network interface use for sending and receive data. As we know, if our system has a 4g network active and is connected to a wifi network too, all network data goes through wifi connection.
I would like to know which is the portion of os that "take" this decision, and if is possible to modify it for manage network connections and traffic forwarding in different way as default (for example send automatically an email with 3g network also if a wifi network is active).
Hello,
I currently use the Samsung Galaxy S9 + with the Android version 8.0.0 Oreo. Currently I'm using a mobile phone card in the network of German Telekom, so I can make calls in the LTE network via VoLTE. I have learned that it should be possible to activate the VoLTE icon by modifying the file "Customer.xml" as soon as I am logged into the LTE network. This change I have also made, but this icon does not appear with me, what can this be? The Wi-Fi Call icon will be displayed as soon as I'm on a Wi-Fi network and mobile coverage is too low. As a network mode, I have also set "LTE only", so that the device can only log in the LTE network. I would therefore be grateful for helpful information. Do I have to change another file? Have I changed too often the entry from "<EnableVoLTEindicator> false </ EnableVoLTEindicator>" to "<EnableVoLTEindicator> true </ EnableVoLTEindicator>", because in my Customer.xml this entry appears for every net (Telekom.de, Vodafone. de and O2.de) and I changed everything from "false" to "true". In addition, I would be grateful if you could tell me whether in the current Android 9.0.0 Pie Beta this icon can also be activated.
Many many thanks,
greeting
You shouldn't need to modify anything for the VoLTE icon to appear. It should appear by default. It does this for ALL devices and OSes.
If you have the Wi-Fi Calling icon appearing then at least you know that VoLTE is actually enabled and working. But I'm not sure why the icon doesn't appear.
You do realise the icon doesn't show when you are connected to a wireless network, right? It only shows when you are not connected to wifi.

I have no reception at work, so I have another phone (with a different company's sim that does get reception,) set up to be a hotspot for my main phone.
I want to use wifi calling so I can make and receive calls with my own number, but it says "not registered on network" when I try. Wifi calling DOES work on my regular home router so I know that it's the hotspot's fault.
I spoke to my carrier and they said I should make sure certain ports are open through the router - the hotspot phone is rooted if that helps.
