I have a Galaxy Note 3 with a problem. When i put my sim card in, it asks for SIM PIN and I type it. Then I get "Emergency Calls Only" or "No service. It wont connect to my SIM CARD NETWORK.*
I have tried/Things I know
-Checking Network Operator and select network from there. Tried also "Select Automatically" still nothing happend. It pops out " Registred on network" but it is not.
- I have changed Network Mode from "LTE/WCDMA/GSM" to "WCDMA/GSM", then!! My network comes up in 5 seconds and go to normal again "Emergency Calls only"*
- My IMEI is not blacklisted! It comes up on screen when typing *#06#.
- MY PHONE connects to the 4G perfectly! I get internet to surf from my SIM CARD! It means the phone is actually connected to the phone. BUT why dont it connect to the operator so I can call?
- Also I have saved contacts on my sim card and then sync to the phone, that means that the SIM is connected to the phone.
This is not a hardware problem, I changed the antenna, but still the same problem happend. I believe this is a software problem.
Everything I change between Network Modes, my NetworkOperator came up in the top corner left in 5 seconds and then went to "No service/Emergency calls only"
I have also factory reseted and installed stock firmware from my country.

Is it possible that mobile network signal happen to be poor at the spot where you are?
Hope anyone others below will help you. Anyway, good luck to you.
The signal is full.

Moto X Play dual SIM. Both SIMs are original (not cut) nano SIMs from two different GSM operators. The phone is not rooted, flashed / reflashed, everything is stock. Both signals bars are full but I am unable to make outgoing calls. I dial a number but no any sound coming from the earpiece - no tones or other party’s voice, nothing, just absolute silence. After some time I hear short “beep”, the line is automatically disconnected and the phone returns to standby. Same happens for both SIMs. I can temporary fix that problem by the phone OFF / ON and then it is possible to make calls. As far as I understand during OFF / ON the phone signs-out / signs-in into GSM networks and that fixes the problem. But after some time it returns again. I several times cleared cache partition and made one hard reset via Settings > Backup & Reset > Factory Data Reset. But that did not help. I also tried various settings for Preferred Network Type (4G, 3G) but that did not help as well.
Please assist.

Thank everybody. Trying to fix “unable to call” problem I was playing with various settings in *#*#4636#*#* menu and did the same mistake as in bablu048's link - I clicked USA band and had no network on SIM 1 (( Having checked I found only one solution – to reflash original ROM. Since I was unable to reflash myself I yesterday gave the phone to service shop and it is now not with me. Once the shop do not fix my phone I shall follow bablu048 advice and let you know the outcome.
I got the phone from the service and it is now working well. They did not tell me what they did, just took the money So, I do not know whether they reflashed complete official ROM of the radio only or somehow reset the radio etc. But GSM network on SIM 1 is back and no "unable to call" problem so far. Once I am again unable to call I will try what bablu048 suggested
Unfortunately "unable to call" is back I shall try bablu048 advice as soon as I can but once somebody have any other suggestions please advise ASAP.
Have you tried with 1 sim card only?
Sent from my XT1562 using XDA-Developers mobile app
No, I have not tried with one SIM only. Actually, that problem is intermittent and it is quite difficult to troubleshoot it. What seems to me is that I am usually unable to make calls when GSM mobile data is turned ON. At least, I cannot recall that I was unable to call when I was in the office or home where Wi-Fi was available.
Is that possible that 3G GSM data somehow prevents voice calls?
Troubleshooting the issue I noticed the following: "unable to call" problem is here when SIM 1 is used for mobile data. If I set SIM 2 as preferred SIM for mobile data the problem disappears. Before I always used SIM 1 for mobile data and faced the problem quite often. But after I turned mobile data on SIM 1 OFF and switched it ON on SIM 2 the phone is OK. Does anybody have an idea why this may happen? Can it be SIM 1 operator-related issue? Can something be wrong with the SIM card itself? Or there is a problem with the device software or hardware?
Sorry to inundate you with messages but I came across exactly the same situation on a Meizu forum. One user there was also unable to make / receive voice calls on two Meizu phones if he enables mobile data on SIM No. 1.
His first post was:
Hello guys. I am using a Meizu MX5 with 4.5.2.7A firmware. My carrier is Orange Romania and I have a problem.
Whenever I activate my data, especially 4G after about 30-45 minutes or so I cannot make/receive a phone call. When I try to place a call the phone sits in the dialing screen without any response, and when I try to call my phone it says that the client cannot be reached. The other functions of the phone work just fine during this time.
To resolve this issue I have to turn the mobile data off and wait for about 15 minutes, or reset the device.
And finally he found the following solution:
Well after a few days with “testing” it appears that (with your help) I have solved the problem.
When you use two SIM cards on your phone, it would be best if the main SIM (voice + data) would be used in the SIM 2 slot because the problems did not appear again. The 1’st SIM slot appears to be able only to handle calls, without data, at the same time. A bit weird if you ask me, but hey…
I was able to keep my data on for days and could place calls or send SMS just fine without any trouble. Swapped SIM cards in my father’s phone also, and the problem disappeared.
So, it seems that SIM slot No. 1 of my Moto X Play is also unable to provide both voice and data. Any idea how to fix that?

If you have unlocked bootloader try these codes
fastboot erase modemst1
fastboot erase modemst2
fastboot erase cache
fastboot reboot
hope it works
The problem continues and I have some update: I have two SIMs, one SIM from Operator 1 and another from Operator 2. If I enable data on SIM from Operator 1 everything is OK with voice and data. And if I go to *#*#4636#*#* in Phone info I see “preferred network type LTE/GSM Auto (PRL)”.
But when I enable data on SIM from Operator 2 after some time I cannot make phone calls as I described earlier. And if I go to *#*#4636#*#* in Phone info I see “preferred network type GSM Only”. And I am unable to manually change that “GSM Only” to “LTE/GSM Auto (PRL)”. It always stays “GSM Only” and does not change.
However Operator 2 is similar to Operator 1, it is also a 3G operator.
Why preferred network type for Operator 1 is displayed as “LTE/GSM Auto (PRL)” but for Operator 2 “GSM Only”?
And why for Operator 2 I cannot change “GSM Only” to “LTE/GSM Auto (PRL)”? Why it is stuck to “GSM Only” when data is enabled on SIM from Operator 2?
More updates… Yesterday (when preferred network type of Operator 2 was “GSM Only” and I was unable to change that type) SIM of Operator 2 was in slot no 2. Today I swapped SIM cards – I fitted SIM of Operator 2 in slot no 1 and SIM of Operator 1 in slot no 2. And now all is OK with preferred network type for Operator 2 – it is displayed as “LTE/GSM Auto (PRL)”. So it seems that network type for slot no 2 of Moto X Play dual SIM can only be “GSM Only” and it is impossible to change it.
Any comments?
I am facing an uncommon issue from past few days on my nexus 6p.
One day all of a sudden phone stopped recognizing my Vodafone sim card, when I tried searching for network manually it gave me only 3 options Reliance, Jio 4G, Airtel.
I tried multiple Vodafone sims, none works. (All of them works in other mobile phones!!)
Strangely Jio sim actually gets detected and lte data works!! (can't confirm calling as nexus 6p does not support VoLte)
Airtel sim also gets detected but can't place calls.
Gave it for repair but after 10 days they suggested there is no issue in sim tray, we have to change mother board!!
Which is very costly. They were not able to detect actual problem.
Can anyone help me if having any idea on what could be issue.
PS: Device Running latest 7.1.2, tried factory reset, flashing couple of ROM (lineage and Pure nexus) without any success in sim detection.
Dude..I'm also having the exact same problem. ..
In my case the signal comes and goes in every 10-15 minutes or so automatically. But after the signal loss it sometimes shows "No Service|Jio4G" and sometimes "emergency calls only" in the Network Tile in Quick settings.. But reboot/ toggling airplane mode temporarily fixes it. Did you also had the same problem or was it a permanent signal loss in your case ( I mean even no reboot/airplane mode fixed it) ??? And also while there is signal I'm not able to make/get any calls or messages from my telenor and jio sim but in airtel I get signal for more long time than the others(max 1hr) and also I can make/get calls most of the times.
God knows what's happening. ..I'm really frustrated. ... Did you find any fix yet? Ive heard some got fixed by repairing their ic by technician in local mobile repair shop.
Thanks!

Almost same thing,For me in case of Vodafone signal comes every 15-20 min and goes, can't make any calls even when it comes. For me jio is working perfectly from last one month. no signal loss.
I am not able to find any fix for it. given to a local shop as well no luck. Will update if I find something.

Hmm.. ... In my case I've tried Airtel jio telenor and none of them are stable... Sad to hear you didn't get it fix even in the repair shop... Maybe that technician was not professional/experienced.

I've got a very weird issue with my Galaxy S8 (SM-G950FD)
After working fine for about 1.5 years on the network it suddenly wasn't able to make and receive calls anymore on the Lebara (Vodafone) network in Australia.
The issue spontaneously disappeared a few hours after it first surfaced but reappeared and has not gone away since.
Internet and Txt/MMS are working normally. But when someone calls me it goes straight to voicemail and when I call nothing happens for a minute or so and then it "disconnects" but no tone
When I go into the phone app and try to retrieve settings like caller ID and/or forwarding it gives the following error:
Failed to read data
Something went wrong. Check your
Sim Card or network connection,
then try again
When I insert the sim into an S7 it's working. When I insert the sim from the S7 into the S8 (Optus network) the S8 works as well.
I've performed a factory reset (without restoring the settings)
I've gotten a new sim and Lebara has ported the number to it but that didn't help
Being a dual sim I've tried using the shared sd/sim slot but same issue.. data/mms/txt working no voice.
I've tried copying the apn settings the S7 displays with the Lebara sim to the S8 but that didn't help either.
I've now used Odin to flash the phone back to the Oreo version with the December 2018 security update and that didn't help either.
Any other ideas?
Thanks
I've managed to narrow down the issue a bit.
Also went out to purchase a Vodafone Pre-paid sim. That one didn't work either at first but after some troubleshooting with support of Vodafone we've found out that the S8 doesn't connect to the 3G network of Vodafone Australia.
When I have the SIM of another provider in there and limited the network mode to 2G/3G autoconnect the phone just finds the 2 other networks on 3G (AFAIK 2G has been phased out).
I've tried to get into the advanced service mode but this doesn't seem to be possible anymore.
Is there a way to try to see which bands are active on the S8 and better yet enable them all?
Guys,
I need help with my network reception issue in OnePlus 6T.
To brief you about its history,
I believe this started from OS Update 9.0.17 where below change-log was introduced,
Re-activated the calling function after the network has been reset.
At present my device is with 10.3.0 OS which is Android 10 based.
In issue description,
1. In some cases I receive network but it will not at all working (like in-out call & SMS). For inbound calls, my device shows out of coverage and for outbound calls it just keep on trying connecting and then get disconnected.
2. In some cases I will not receive network reception itself.
3. Issue reported with BSNL Network only. I tried with 3 different BSNL SIM and issue remain same for all.
4. No other network is affected (irrespective of 2G/3G). I tested with Airtel & Vodafone, where its working with 2G & 3G both.
Troubleshooting steps,
1. Tried flashing device completely (From OS & Recovery Both) - No Solution
2. Tried downgrading OS to 9.0.4 - No Solution
3. Tried selecting 2G network manually - It throws error as selected network is not available.
4. Tried changing Network Reception Scope to GSM/WCDMA only for BSNL Network slot (SIM2) - No Solution
5. Tried using BSNL only in SIM1 slot (keeping SIM2 empty) - No Solution
6. These same SIM Cards (JIO & BSNL) are working fine presently in my another OnePlus 5 device.
7. Tried disabling DSDS (Dual SIM Dual Standby) from *#*#4636#*#* but its not getting deactivated & remained active always.
I verified with Network Cell Info Tool where this BSNL network is showing greyed out (I dont know what does that mean) but I believe its representing internal root cause of this issue.
In app, neighboring cell is also losing connectivity randomly and not steady for BSNL network only.
It seems I've hit the same issue with my OnePlus 6 since the last couple of days. Happened after I did a 'reset network settings'. No solution yet. I have changed to a new BSNL 4G SIM and had factory reset of the phone.
Now the phone is with the service centre.
How did you resolve this issue?
