I have seen that problem several times but it was always on T-Mobile and it was always a switching problem. I don't know if Metro using the same setup or not. You could check in settings and make sure you are using the preferred network.

Yup on preferred network,frustrating I can't figure it out.

Mobile Data Randomly Being Disabled

I have recently switched from Straight Talk to an AT&T 10 GB Mobile Share Plan. Since then my mobile data will randomly be turned off when i'm connected to wifi. It wont turn back on when i disconnect, nor when my device receives (or attempts to receive) an MMS message. Is there some setting i may have accidentally accessed since the activation? I don't have any programs that are capable of changing my device status like that (nor is my phone rooted).
Dont get me wrong, i'm glad something is trying to help me conserve battery haha, but it does get annoying since i only notice it when i get a notification that my device is unable to send/receive a picture message, or that i have no data once i leave the wifi network.
Its just weird since it has only started happening since switching to AT&T Postpaid.

Which ROM are you running? That is strange. It could be something with the APN as well. Are you on LTE or stuck on 3g? Maybe your phone is stuck in one and tries to switch from LTE to H or vice versa? I know when my phone chooses H instead of LTE (I use Cricket, but same towers) it takes quite a few seconds to get a data connection to load, but LTE is pretty quick to load.
It doesn't actually save battery to have data off when using WiFi since that is already happening behind the scenes. Not sure why yours is toggling the setting on its own but perhaps a factory reset would fix it.

Everything is stock. I had a APN automatically assigned from AT&T that caused me to constantly switch from HSPA+ to LTE. I found a better one online and now get LTE most of the time. I never really gets "stuck".Its not that the data isn't loading, its that it is literally set to "mobile data off" on my device, and i have to manually turn it back on in the settings. I wasn't aware an APN setting could change other settings on a phone?

VOLTE on rooted device?

Anyone know how to get VOLte working on their Note 5 while rooted?
It worked on my Note 4 using stock kernel, or an older version of Emotion kernel,
but haven't been able to use it yet with rooted Note 5. The call always fails before connecting.
VoLTE worked fine on my rooted N5 using 2 different kernels. Unfotunetly I get dropped calls when driving by certain parts of my area so I have is disabled.

Are you sure it was actually using lte for voice? The only reason I ask is that when I place a call with the 'use VoLTE when available' option checked, my phone always switches to 4g before connecting the call.
If I try making a call while in "Lte Only" network mode the call just ends instantly, as soon as I hit send.

With VoLTE enabled my phone stays on LTE when making a call (when LTE is available). With VoLTE disabled my phone will always switch to 4G when making a call & will switch back to LTE as soon as the call has ended.
VoLTE works fine for me if I'm stationary but when I'm driving through certain areas where LTE service is spotty I get dropped calls. I don't have that issue with it turned off.
This is exactly what I experienced before my phone was rooted also.

Note Edge 915T Wont let me call while on LTE - Help needed :(

Hello all..
I have this issue with my Note Edge 915T (T-Mobile Variant). It is unlocked and I use it in Venezuela with Digitel (LTE BAND 3: 1800) and the phone DOES connect to LTE with no issues (I get the 4G/LTE icon), and I can browse with no problems, but no one can call me, nor can I make any calls or text. In other phones, when I call, data drops and I can call and when I finish, data comes back up. HEre, LTE stays up and my call does not get through. Then after some tries, it drops to EDGE and won't pick up LTE until I reboot or something.
If I try a different operator, it goes to HDSPA (3.5G) and I get voice and data (data drops while calling, but it ir normal), but I want to use my operator with LTE.
Im running MM and I deactivated VoLTE as my carrier does not support it, but is there something else I'm missing?
This may sound stupid, but have you set your APNs? You can also try resetting your network. Dial ##72786#. Also Does your carrier require any certain apps. Example FreedomPop requires a specific app for getting/making calls, as they are mainly VOIP MVNO...

Hi! thank you but yes, the APNs are perfect, I can use Data, the issue is that I cant call as the data signal stays in 4G/LTE and with my carrier, when calling, it drops data signal and it calls, here I can't. Im starting to think it has to do with CSC being with TMO, and I should use another one either from my country or a general One (BTU) for example. Will try to flash a rom from a different carrier to see if it works.
The only other option might be *#BAND# (2263),which could be dangerous, if you do not note original settings. Sometimes a complete ODIN can restore.
I normally use Nova Launcher - Widget- Activities- Somewhere under phone or settings. Shortcut Called PhoneInfo or DeviceInfo, which is much safer&consistently works! The app w/ same name no longer works. It took me forever & I always export my desktop, so I have that shortcut. The last option is an app called Samsung Phone Info+, but is paid or free if u know.... I really hate paid apps. It has under menu secret codes as well.

How to enable VoLTE for LG V50 (Korean U+)

How to enable VoLTE on the korean U+? I've checked with my carrier and they confirmed that VoLTE service is active on my SIM. However I can't find any option to enable VoLTE in phone settings. I've only seen a VoLTE call quality option in phone settings - not sure if this means that it's already active. The status bag logo also shows just LTE when mobile data is enabled - no indication of VoLTE.
If you have mobile data showing LTE and it does not change to 3G (or something else) when you make or receive a call, then you are on VoLTE. That is my general understanding of it.

Ah ok. It seems you are not on VoLTE then. Sorry, I don't know how to activate it though.
i have the sprint version but am currently on tmobile network which (was switching me to 3g) during voice call or txt msg.
now that tmobile has been taking down 3g (and they are working on a tower in my area) i do not even see 3g symbol in notifications anymore. i can complete the call and there is no lte symbol or 3g symbol but call completes but can not use data still.
when i hang up i see lte and can use data (browse the web)
the funny thing is before i went to tmobile i had metro pcs in this area which uses tmobile network and i never had a volte problem so you know this is software and they just want us to buy more phones.
this exact phone worked on metropcs with volte no problem.

Question Switch mobile data automatically during call

In pixel 7 pro, Can we Switch mobile data automatically during call so that data is active during call.
This was available in oneplus
Hmm, I anyways lost connectivity with my OnePlus phones are well when in call...
What country are you in? Possibly carrier-related. With US Verizon this isn't an issue. When I was roaming in another country this issue popped up.
Interesting. I'm in Greece. There used to be a time that connection didn't go down but I never figured out the specifics of why.

Are you sure that you're not referring to VoLTE?
If 3G is shut off on your network and you don't have VoLTE then you call with 2G
2G doesn't permit data session with a call going on
Really not sure. All providers here support VoLTE but not sure how to check it. I think there used to be an OOS version that showed an indication for such calls but I then lost it.

All you need to do is to go to Network and Internet - SIMs - VoLTE (turn it on) & Preferred network type ( set it to LTE or 5G).
