Yesterday, my phone was working fine. Today, I wake up and instead of showing H or E in my signal bar area, I just have the bars which are full.
I can send and receive texts, but no photos. No webpages are accessible, email won't sync etc. But I can still make and receive calls as well.
I'm running Neutrino V2.5. This morning I flashed the 36P radio (from 30P) in hopes that might help. Didn't change anything.
Not sure if any of this is needed but here it is anyway:
Signal Strength - 93dBm 10asu
Mobile Network Type - HSPA
Mobile Network State - Disconnected
Wifi is still working fine as well.
Any help is greatly appreciated!

I'm experiencing the same issue. Not sure what's going on. I went into settings to search for available networks and it's been "Searching" for like 15 minutes. Behind the "Searching" dialog I can see two options for AT&T and looks like one for T-Mobile. If I try to press back to cancel the search, it just takes me back to the last screen. I've also tried resetting APN. ugh.
Check the APNs configurations you might have to set them again.
I read over Atrix Dev that there's a weird bug in Neutrino ROM 2.5 that remove the APNs.
Settings -> Wireless & Networks -> Mobile Networks -> Access Point Names
Hope that helps
Note: Closed. Problem solved by flashing newer version of country radio.
Hey guys,
I am running PA 4.4Final with the stock kernel. The radio was working perfectly fine for 2 hours on roaming, but then randomly stopped working for the past 2 days. I am now back on my home city network and the issue remains.
The cell phone is receiving a healthy signal and even identifying available networks. But for some reason, any manually selected network isn't "available", and if I keep the setting to automatic selection, I get only emergency calls status. The service status is also "out of service" ?!
I'm attaching thumbnails for your benefit. WiFi and other wireless services are working fine. Is this a Samsung problem, or a software one?
Partial fix: I flashed the new Indian modem. Now I am getting signal and network. But I cannot hear anything on calls. =/
Hey guys, I have a T-Mobile branded Galaxy S5 (SM-G900T) that I'm using on Metro PCS and whenever I connect to wifi I can't receive mms messages. I will get the text and it will ask me to download the image but then I get a never ending progress bar. So then I'll turn off WiFi and I will have bars but the 4G LTE indicator will be gone and the only way to get it back is to reboot the phone. Any ideas as to what this could be? I have tried using both the T-Mobile & Metro PCS APN settings but the issue still happens no mattter which APN the phone is set to. Any help would be greatly appreciated. Thank you!

No ROM, it's stock.
wifi calling enabled and set to only make calls on wifi?
This will happen when you have wifi calling enabled. That is why you see the cell signal bars go gray or grayed out. Turn off wifi calling and you will see you signal bars come back, as long as you have cell signal (service) at your house.

Having WiFi calling enabled won't affect your data and messaging at all unless there is a connection issue with the router.

It sounds like a connectivity issue on the routers side if the APNs are correct. I would go back to Metro PCS APNs then check your signal strenth and link speed in the phones WiFi settings, then check to make sure WiFi calling does not display an error in the call settings. If all 3 are good then check your client list on router and make sure phones IP address and MAC id is there. If IP and MAC id are good run diag log on router and possibly change/test different wireless channels on your router.
I never have WiFi calling enabled so I don't see that as a cause, and I have tried both the MetroPCS and T-Mobile APN settings and it still happens. I'm still able to receive calls and send text messages but I can't receive MMS messages or access data. The only way to fix the issue is to turn on airplane mode for about 10 seconds and then turn it off and I get the 4GLTE signal indicator back along with full service. Its really weird because when this happens, I still have a signal indicator with 3-4 bars but the only the 4GLTE indicator disappears.

I will get the same issue as stated above. When you have bars present with no data icon, its because your phone is latching on to another network when MetroPCS is not to be found. At my office, T-Mobile service is the pits, yet i get bars present. I usually open the dialer and type *#0011# and it will show what band your phone is picking up, from there you can tell if you are really on MetroPCS or someone elses network.
Can anyone out there see if they get the same behavior as me?
I'm in a band 12 area, with a 4 bar LTE signal.
Wifi calling is enabled but CELLULAR PREFERRED, I'm connected to the T-Mobile ASUS router on Verizon FiOS (2.4, 5ghz, doesn't matter).
Long press 1 to get into your voicemail. What you expect to hear:
"You have no new messages in your mailbox..." is chopped off and what I hear is:
"mailbox..."
If I turn off wifi, the issue goes away. If I turn off wifi calling, the issue goes away. If I change the wifi calling setting so that it uses wifi preferred or always (so the call is an actual wifi call), the issue goes away. If I force the phone to use HSPA, the issue goes away.
So even though the call isn't a wifi call, something about wifi calling and wifi, even though the call goes through VoLTE, is causing the start of a call be be chopped off.
At this point I have disabled wifi calling on my phone.

I have the same set up, I'll turn off WiFi and report back, as I've noticed the same issues...

Seems better... I'll keep it like this and see...

My theory on what's happening here is this:
While you're telling the system too use VoLTE and setting cellular preferred, it's starting the call on Wi-Fi calling and handing off to VoLTE.
The reasoning it's simple...when on Wi-Fi, cellular data is deactivated. VoLTE depends on cellular data. When you start a call, it establishes it via Wi-Fi calling, and establishes the cellular data connection. Once that connection it's up, handover occurs, but this causes a few seconds of Audio loss because it has to set that back up.
You can see the delay yourself by turning off Wi-Fi, then turn off mobile data. Turn mobile data back on and you'll see the delay between enabling and being reconnected too the LTE network.
Hope this helps explain the issue. It's a handoff delay caused by having to reconnect mobile data and LTE, and you likely wouldn't notice for normal calls, but VM answers immediately.

I understand what you're saying and thanks for the explanation. And I realize that when wifi is on, data is going through wifi and would have to switch to LTE for a call. So this does make sense to some extent. But.... if wifi is on but wifi calling is not, the calls happen quickly and are not chopped off. But the same holds true - the data is going through wifi and would have to switch to LTE. Your reasoning explains it for wifi calls always and wifi calls never.

That's because with wifi calling ON, the call is initially set up through wifi calling, and has to hand over once the mobile data connection is up, LTE is negotiated, and VoLTE is negotiated. If wifi calling is OFF, the call is established via GSM, then (optionally, but not usually) handed over to VoLTE once LTE is up and VoLTE is negotiated.
I've done work in the industry with VoLTE, and my day job involves VoIP, so it's not as simple as one might think. Believe it or not, GSM to VoLTE handoff is much easier than WiFI calling to VoLTE. It still explains it, believe it or not, it's just a matter of which path. It's also harder to hand off from VoLTE to GSM when you roam out of a VoLTE area... which is the primary cause for VoLTE call drops.

Why haven't they implemented that then? That hurts them in the rootmetrics etc. scores where they'd test phone calls.
For example, band 12. You make a VoLTE call, drive to out of range of LTE and the call drops to HSPA or Edge. It nevers goes back to LTE. So when they're doing their tests, if the call switches away from LTE, then they drive to an area that is band 12, when the HSPA signal gets weak, the call gets dropped even though there's a great band 12 signal.

That's actually a great question...and unfortunately one I can't answer or even begin to speculate on...

Back to my original point though - what I'm hearing is that this isn't unique to the V10. I'm wondering why this isn't all over the internet where people are noticing that the start of their phone call is missing when wifi calling is enabled but they've set it to cellular preferred (which is NOT the default BTW).
Hello all!
I have a Samsung A01 (SM-a015AZ) unlocked from Cricket, being used in Pakistan. Internet over LTE works perfectly, however the phone does not support VolTE and so it is only possible to send sms or call over 2g/3g. There's no problem when making a call as the phone automatically drops from LTE to 3g, however that does not happen when someone else tries to call me. The phone does not drop from LTE, nor do I even get any missed calls/sms notifications, but to the person calling me it seems like my phone is unreachable.
There are 3 options present in the preferred network mode (LTE, 3g, 2g) If I set it to 3g, all calls work fine, but with really really bad internet (EDGE). I have even tried to see if any settings in the advanced network configuration menu (By dialing *#*#4636#*#*) would make a difference, however I've had no luck so far. I would really appreciate it if someone can help me with this.
tl;dr Samsung A01 drops from LTE to 3g to make calls, however does not drop when someone else is calling and so does not receive any calls.
