I have n9005 rooted TouchWiz stock on 5.0,
when my phone is on LTE mode i'am unable to make/receive calls.
Kindly help me solve this problem.
Is the phone set to LTE only? If it is, does the carrier support VoLTE?

LTE/4G is a Data-Only network. To make calls over it your carrier needs to support Voice Over LTE, or VoLTE for short. Which is the mobile equivalent of VoIP.\
If your carrier does not support VoLTE, and your device is only allowed to access LTE, you can't make calls. Change to 'LTE/WCDMA (Auto)' (4G/3G) or 'LTE/WCDMA/GSM (Auto)' (4G/3G/2G) mode so the phone can automatically change to a network that supports voice codecs.

How about switching to wcdma/gsm or wcdma only?

Something appears to be preventing the automatic switch from LTE to 3G/2G. Did you do something in the Servce menu?

My device didn't had the LTE option first so i did something which i don't remember now, what it was, i did it when i never used LTE, but as now i'm using LTE and came accross this problem. also i have installed a network type toggle app.
Sorry for being such a nub but where do I go to change the mode? Option > network operation? Thanks

Not receiving incoming calls on AIRTEL 4G LTE
Iam facing peculiar problem with the phone. Need help with the problem.
I am using samsung note 3 LTE. When ever some one tries to call me, my mobile is Not reachable or out of coverage area even when my mobile is in my hand , perfectly working with the second sim. outgoing calls are working fine. Again, when I am in call, then if any one tries calling me, then I get call waiting. So incoming call waiting is working for me. But incoming calls are not able to connect. LTE data is working fine though incoming calls are not working.
Tried the following but no luck. Problem still persists:
1. Reset phone and erase all data
2. Hard reset phone (volume down + poweroff and clear all data in drive)
3. Tried changing SIM to second slot
When I switch the sim back to 3G mode or 2g mode , incoming calls are working perfectly fine . I googled it and found that most people had same issue and was resolved on switching back to 3G or 2g .
But I need to use 4g . Please tell me a solution.
I had that same issue until I took my note 3 to Rogers and they said that the note 3 doesn't support Lte
Your rom must support VoLTE.
I would unroot and go back to stock firmware, and see if problem still happens,? if it does ,its most likely the sim card.sd card reader slot, (flex cable),my Galaxy s4 had the similar symptoms , but LTE would work with a custom rom, but not if I used stock firmware, replacing sim card reader flex , just google your mak and model and search ebay. mine cost a few pounds for a decent quality part, so dont go rushing to buy the cheapest. No problems since replacing that part, even after resetting phone 3 times to see if it was a fluke. I know its a bit late for a reply, but this actually worked , I am 99% sure it would work for anyone else who has this problem with lte not connecting when 3G, and 2g do connect. If you have tried swapping sim cards, putting sim in another phone,, etc,etc. this part mentioned(sim card/sd card reader) is your culprit. Took me just over 5 hours of testing to find the solution. thanks and fair well android users

For many people having issues with LTE not connecting and diverting to voicemail on android, I am here to offer a solution to your woes. I have a Samsung Galaxy S4, GT-I9505, and recently in in 2018 in July, I had the same problem, phone calls connected on Gsm, Wdcma, BUT when I tried LTe mode, NOTHING, WENT STRAIGHT TO VOICEMAIL.Anyway I tried almost everything mentioned on certain websites and forums, with some luck, Changing LTE mode to GSM worked, and I could receive and hear phone calls. So I investigated further, I tried re flashing stock firmware, factory resetting phone.(nothing worked). I then rooted my phone and flashed a custom rom (do not try this) as it could damage your device if flashed wrongly. Yeah, so I flashed a custom rom, and low and behold problem disappeared, so I used my phone on LTE for 2 days, with no problems, I then decided to go bacjk to stock firmware, ...problem came back, not connecting to LTE mode..........being as patient as I can be, never gave up, and had a spare phone which was dead, just laying in the drawer, ..so ,I took phone apart and thought, it must be where simcard contact make contact with sim card reader contacts ( broken sim card /sd card reader part, and was I wrong, no, it actually was the sim card reader part which coonects with th motherboard, Voila, I am 99% sure if anyone else has this problem with any android that has LTE capabilities, and you know its not the sim card, then try this fix first, MAKING SURE YOU GET SOMEONE YOU KNOW TO HELP YOU , IF YOU ARE UNSURE OF WHERE TO BUY AD HOW TO FIT. hope this has helped,and I know it is a long thread, but hopefully it will be a solution that works for whoever reads and trie this, over and out. yours in sincerity, Tech82, from Surrey, England.

In fairness post might be useful to some .
Where it is actually the sim holder .
But 99% of the problems are not the sim holder .
Though very odd that S4 user makes only one post and that's on a Note 3 forum not his phones forum .
i am facing the problem with my LGF180
This is Note 3 forum not your phone .

That's expected because JIO is a 4G only Mobile service.
Any Dual SIM device can have High Speed Network on any 1 of the 2 SIM slots and the other one will always remain on 2G. So whenever you are enabling 4G on Idea's SIM Slot, JIO's SIM Slot is being changed to 2G only and JIO can't receive a Signal in 2G mode. I am not sure but I have heard that in few Cities in South India JIO has partnered with BSNL to use it's(BSNL) network on 2G mode but I don't see how it's gonna work or even if it's true or just a rumer.
So, if you want to use JIO you need to have 4G enabled in it's SIM slot and make another one 2G.
Hope I was able to make your confusion clear. Feel free to ask back if you have any more questions.

Sir ,
I am using Jio 4G sim card in my Note 4 , but if i change and insert any other oprater sim then its showing network but i cant make a call and send a massage or use Internet. I was inform to customer service then they told me that your have used Jio Sim so nothing any options to recover it. So please anybody please guide me properly . Help me please .
You can use any sim. When you change your jio sim, makeep sure that you have selected auto in network mode instead of lte only at the same time you have to select the correct apn in Internet settings. Jio sim will not lock lock your phone to that network. .. using jio on note 4, j7 2016, j2...without any issues
Has anybody tried the G950FD on T-Mobile and AT&T in the US? Ideally Tmo on SIM1 and ATT on sim2.
I know the S7 couldn't switch well between the two networks as a dual sim phone.
Also is WiFi calling working? B12? Is SIM2 3G on AT&T or still just 2G?
Thanks!

I've done some more searching so let me clean this up for future searchers...
Q1. At&t will not work well on SIM2 since they killed their 2g network. There does seem to be a 3g antenna in SIM2, but for some reason still requires a 2G network. Tmo works fine in SIM2.
2) Tmo WiFi calling is not working. Though there is hope that this will work in the future (with root). Not much hope for a native solution.
3). Volte (b12) does seem to work with certain country modems. But as of today, its not clear which countries.

thanks for info
I have international S8 SM-G950F.
Recently, I switched to Ultra Mobile and contacted them about using VOLTE because they advertised it.
Ultra Mobile is a MVNO of T-Mobile. The reason I contacted them is because you need to have a SIM that is provisioned for WiFi Calling before it will work. I tested this by going into Connections, then Data Usage, and finally Mobile data. (Turn switch off and then try using the phone or sending MMS. Mine worked. But remember I contacted the carrier after they advertised that they have WiFi Calling....

There could be 3 possible ways.
1) Software bug
2) sim slot pin breakage
3) sim card chip problem
Identify the root cause at first.

2nd and 3rd not possible. Since data and messages are working.
Can you provide more information.
Are you on 4g network.
What type of error do you get.
Your circle.
Have you changed your network settings using *#*#4636#*#*?
Have you tried calling using 3g and 2g only?
If not choose WCDMA only (use above code). Also try with GSM only.

Same problem here. Solution for now is to change to 2G network, at least for me. When I try to call with 4G preferred sometimes it work, but when it works they can't hear me and I have to scream. This Pie update have so many bugs it is ridiculous. I can't believe they put such ****ty update to the masses it seems like BETA version. In Oreo when making call phone switches from 4G to 3G instantly now in Pie switches worry slow if it even switch and the signal is so bad that the call drops and that is in places where the signal is perfect
Hi, since last 4 days i am facing same ptoblem cellular SIM in slot 1 not working for incoming and outgoing calls and outgoing sms but internet and sms service (invoming) is working perfect on 4G

I am using poco x3 nfc
I anyone have solution plz tell me
