No phone signal yet can use mobile internet

I've got a strange problem that I cannot solve or find anyone else that has had the same problem.
I recently updated to Minco V4 and since my status bar has been showing no signal and mobile standby shows 100% without signal yet I have mobile data. I cannot make any phone calls but can browse the internet. No amount of rebooting, airplane mode on/off will work. I've also gone back to both stock ICS and JB where the problem still exists.
My network is T-Mobile and it won't let me manually connect to it but the phone will occasionally register when I select automatic although it doesn't correct the fault. Anyone have any ideas what has gone wrong with my phone?
UPDATE: It seems I can only get a phone signal when select 2g T-mobile network only or connecting to T-Mobile orange. If I untick 2g networks and it connects to t-mobile 3g I can't receive or make calls.

Does your Radio and baseband match?

I installed the linked radio from the MiNCO thread after flashing the rom and discovering this issue yet it made no difference.
I got a phone signal momentarily about 15 mins ago which allowed me to make a short phone call to test it. I then accepted the JB system update from Google and now have no phone signal, just data.

Missed calls not showing, and late SMS

I'm having issues when on WiFi and LTE Enabled, the phone does not get any phonecalls, missed phonecalls do not show and SMS arrive late (my carrier has the option to notify me missed calls, but yesterday the message got me 10 minutes after the call).
After searching, I've found out something similar happened to nexus 4-5, when WiFi is ON, LTE is ON, and the phone is in Sleep Mode but nothing on Zenfone 2. Have a friend with ZF2 that confirmed it happens sometimes but we doubt if it' s a phone issue or carrier issue.
Getting the network mode to 2G/3G seems to fix it, but it misses the LTE

try to restart the phone (?)

I reboot my phone every couple of days, but the bug sometimes appears in the phonecall right after rebooting

What messaging app are you using? I know I miss messages from my wife when I had textra in the "off" state with autostart manager. When I told it to start when the phone boots it started getting the text messages and mms's right away. Are you using a VPN or do you have weak signal and what firmware are you using?

make sure phone is allowed 2g/3g/4g all. If you restrict it to 4g only you will face such issues.

I usually reboot in the mornings. But I US Google voice so the issues never really show up.

Stock FW (was on 168, now I'm yesterday patched versopm) , Stock SMS, no VPN, and set to 2G/3G/4G
As I said, the problem is fixed when I'm on 2G/3G, but it kinda loses the point to have an LTE plan

can you test with 4g on and wifi off.What carrier are you on. Because carriers can use wifi and lte combo in case you have same carrier providing both facilities.

I'm on Uruguay Antel and it does not offer any combo whatsoever, voice calls are usually switched over to 3G when I'm on LTE, but somehow the network or my phone fails to switch sometimes

Dual Sim issues

Hello,
I'm using two swedish providers in my phone - 3 and Telenor. Both are capable of LTE/UMTS, I'm using 3 as the primary provider for all options in the Sim settings and the Telenor one only to receive calls.
So I recognized a problem where my data connection would drop when the 'open wifi'-notification popped, I tried to disable that and it seemed fine at first. However I'm still getting data connection drops when me phone swaps from LTE to UMTS(3G/H/H+), no errors are thrown and I'm only seeing it due to no data loading within apps or disconnects in-game, the display isn't dropping the coverage indicator nor the indicator for which network is being used(3G, H, H+, LTE, 4G+). After some time the data connection returns but keeps dropping rather frequently once this pattern starts.
Airplane mode restores connectivity for a while (I haven't clocked it) but eventually the connection stops receiving data and the disconnecting pattern returns.
Calls and SMS are working as far as I've noticed so far.
Any ideas?
Edit: I've restarted the phone multiple times.

Any one got similar issues or any fix :3?

network issues

Currently I am in stock room.
My phone suddenly drops the network (Wi-Fi and cell network) but it is not in airplane mode.
I won't be able to receive any calls, but the caller will hear busy tone.
During the whole time my network shows few bars, but it is probably fake network.
I am just missing many calls due to this problem, and when some one notifies over other phone I will get to know and I will put into airplane more and back, the network resets and works fine.
Can anyone know what is the problem ??
I have reset my phone also, but of no use.
Thanks in advance.

Question Phone Suddenly on Emergency Calls Only Until I Restarted It

When I woke up today, I saw that my phone was on No Service and it wasn't just flipping between full bars and no service for a second like it too often does (including dropping calls a couple of times). I tried to fix it by turning Airplane Mode on and back off, but it did nothing. I went to try to manually choose a tower to connect to mostly to see if the T-mobile tower near me was working or not, and there instead of a tower name it said "Emergency Calls Only". It did let me pick from the list and a disappearing pop-up said it connected, but it never changed to signal and stayed on Emergency Calls Only. So, I restarted my phone. Once it was back on, I had signal, but strangely I also got a Gmail notification about an e-mail that had arrived an hour prior, so I guess even my WiFi wasn't working! Bluetooth did connect fine to my Apollo Neuro anti-anxiety device, but the app was messed up showing it at 100% strength on two different settings instead of the strength they were saved at (and were sent to the device at), which was weird. Everything was fixed after the phone restart.
Anyone else had this happen? The signal issues on this phone are really starting to annoy me! Flipping to no service for a second too often, not connecting manually to any other tower (my plan includes unlimited roaming for talk and data) [I'm not sure if auto roaming works since I haven't been where it would be needed], dropping a couple of calls, not sending texts at times, Chat texting dots turning off often (usually fixed by going into Airplane Mode and back), and now this! I love the phone, but they need to fix it whether it is Samsung or T-mobile!

i thought i was the only one. suddenly no service to any calls but data intact. only way to fix is by cycle flight mode.

That sucks. They really need to fix this basic function of this phone!

I've had that issue when getting in areas where coverage is spotty, but never been able to see it go into Roaming..........just "emergency calls only".

It seems that is the issue, that the phone won't roam. That is a mega problem.
My phone was just sitting on the wireless charger all night, and I get full bars (occasionally minus one) here at home, so .
