Can somebody please help me regarding this should i have to do some tweaking for this have anyone faced this issue
Same situation ^^^^^^^^^^
It seems as though Ive found my twin on XDA lol......I just purchased an Unlocked Tmous tab froma friend and it's details are as follows:
Model: Gt-P1000
Baseband: t849uvjjb
Kernal: 2.6.32.9 ([email protected] #190)
Build number: Overcome v1.6.3
I want to be able to have calling work as well, (exact same symtoms as OP..)calling starts then "Call Ended" and as of right now, my text messaging and internet (edge network for both of coarse) are working fine. Hell, I even my wireless hotspot, "Mobile AP" in Galaxy speak, works fine. I work for an At&t retailer, and Im rocking a TMO tab lol...wish I could have both 3g data and voice :/..... Where do I start?
Found this in general section - http://forum.xda-developers.com/showthread.php?t=838250
Thanks !!! but i didn't resolve my issue.... any more inputs please i have overcome 2.01 rom as well on galaxy tab i can browse using at&t and make calls with t mobile but i am getting a login page once i try to browse with t mobile
Have you checked your Apn settings? I just got my calling to work on at&t finally, and my sms and data are working great..only on edge data though until I score an at&t tab someday. I merely needed modem file that I found here on xda...ill find the link. (and also thank the appropriate user)
Sent from my GT-P1000 using XDA App
Yup got it worked but same only on edge trying to make roto's modem switcher to make it work
Sent from my SAMSUNG-SGH-I897 using XDA App
At&t and t-mobile don't share the same hardware so they don't get 3g on the others network.
Hello guys! I've been reading these forums for a long time, amazing what you guys do in here
Here is my problem: I live in México, and I traveled to USA for summer vacation, my mexican mobile phone carrier uses 850mhz (TELCEL) and when I went to USA it was using ATT's network.
So everything was working fine, but when I returned just before I was about to cross the border, it stoped working!
It has a message that says ''Emergency calls only'' where it's supposed to say ''TELCEL GSM'', so no internet, no calls, no messages.
I was using Froyo on my phone, and thought of doing a reset to restore factory settings on the phone, but it did not work :/
Then I updated my phone to Darky's Rom 10.2 (Gingerbread) and it's still not working!
When I go to Settings>Wireless and network>Mobile networks>Network operators I can see that my carrier is available to select, but when I try to, it gives me a ''Unable to connect. Try later'' msg.
It is really frustrating because I depend on my phone so much, mainly because I share my 3G connection to my laptop for school's work and stuff.
There's one weird thing though, I unlocked my phone, and placed a MOVISTAR(1900mhz) SIM card on it, AND IT WORKS!!!
But the thing is that I don't have internet on that SIM card(is prepaid and it's EDGE, not 3G), and on my TELCEL SIM card I have a contract to complete (still a year to go).
When I put my SIM card on someone else's phone, it works like a charm, but if I try to put a TELCEL (850mhz) SIM on my galaxy; just says ''Only emergency calls''
What do you guys think happened to my phone? I would really appreciate your help.
flash a new modem... one that contains more frequencies enabled.. any bell or telus will do.
UGKC1 modem should fix your problem.
It did not work, should I keep trying with other modems?
you can.. jk4 or jl2 are other modems with 850 and 1900 enabled... maybe your problem is different then I thought... but it sounds like your modem... maybe try unlocking your phone? if you can connect to wifi download sgs unlocker pro (paid app) in the market to unlock, your phone also needs to be rooted. are you using the i9000T? that may be different problem altogether...
edit: sorry I see you said it is unlocked... just doesn't sound like it...
a) modem related (ugkc1) should have fixed that
b) SIM carrier not compatible to phone (unlock phone to fix)
c) Busted SIM card, check in other phone
d) make sure phone option is set to Automatic CDMA/GSM
sounds like you checked everything I would check....
does your 3G work... make sure your VPN is setup to your carrier
maybe imei got blocked...? only way around that is to get provider/samsung to unblock
Hey have you solved this, I have the same problem

Hi does anyone else have disappearing calls when connected to LTE using a tmobile based s6?
This issue only occurs when LTE is active.
An incoming call will ring once or twice and go straight to voice-mail even though I have full bars

Go to your Phone App settings and turn off Wifi calling and VoLTE.
I'm sorry I have already disabled WiFi calling, and the problem persists but also - I don't have a separate 'VolTE' setting to toggle. Is it because it only appears if I have a T-mobile sim card inserted?
Thanks for your help!
EDIT for anyone who may run in to this issue: I fixed this by flashing Emporia Rom by iB4STiD, it seems to disable whatever t-mobile left over sorcery that was messing with AT&T calling because the rom is not based on t-mobile firmware
Now the calls come through 99% of the time but sometimes takes about 5 rings to connect to me. . arrr

happens to me on even international firmware too. only works well right when i reboot the phone.
I have this issue also with a tmobile s6 on att. What method did you use to unlock the phone? I used the metro pcs firmware to unlock the phone and when I updated to 5.1.1 is when all the issues started. On 5.0.2 I used the tmobile unlock app and everything worked perfect. I receive one in every 3 incoming calls, like you said it rings twice and mine doesn't even go my voicemail, it just says "the wireless number you are trying to contact is unavailable then hangs up", out going calls take 30 seconds to a minute to connect, very annoying. Talked with att on the phone for hours about this problem and they cant seem to get it fixed on their end.
Same...I disabled lte and just use 4g, seems to work fine.
Hi.
For those who don't know, Freedom Mobile (formerly Wind) is a T-Mobile equivalent network here in Canada, but until recently they launch a new LTE network and their site says I can use my N900A. I used their phone compatibility checker to confirm (see attachment)
However, I bought their sim to test, I get LTE data and works fast, but I can't make phone calls. It just sits there doing nothing and finally hangs. I checked the simcard on another phone and it works, so it's not the sim.
I'm using the lollipop OC1 firmware stock only. What could be the issue here? I appreciate any input.
EDIT:
My phone is unlocked (RegionLockAway) a while ago.
My *#2263# is set to Automatic.
Do calls work on the Bell, Telus, or Rogers network?
Since there have been a few posts about people wanting to get their non-AT&T S9 working on AT&T with all the advanced features, I figured I'd post some tips since I have 2 S9s that have been successfully converted.
1. You must come from a U1 firmware to the AT&T U Firmware.
2. Make sure your Sim Card is fairly new. I have had sim cards work in an older phone but not a newer one.
3. Have AT&T hard set the IMEI of a AT&T branded phone(that supports wifi calling). Do this by putting your sim card into the AT&T branded phone and call AT&T customer service and say your Wifi calling and HD Voice are not working.
4. Make sure Wifi Calling was active on the AT&T branded phone before moving the sim card to the S9.
Also make sure you have ATT csc installed. There are a few required apks that are in the odm folder. I was able to get it working on a SM-G965F
I wonder what else could be tried?
I have done all of the above coming off a brand new unlocked U1, flashed the U FirmWare with ATT User data file. I can actually setup WiFi calling on the new handset (it doesn't really work ,however) and about 10 minutes later I get a provisioning failed message.

The other phone you have with wifi calling provisions just fine on the same wifi network?

Funny you should ask this. Up until last night I could swap the SIM into the old phone and WIFi calling would provision and work. I tried this morning and the old phone is now giving me the same "ooops... we cannot provision..." message. I was thinking bad SIM card again? It's 10 days old though.
EDIT: Chatted ATT and verified they have the old IMEI set from the old phone that had working wifi calling.

I've had provisioning fail on certain wifi networks, do you have somewhere with stable wifi where you could try again?

I will be at work tomorrow which is located near the ATT store also and at work I have access to a fiber fed service with WiFi for "Non Work" use that is great and I will try that. I have Gigabit CATV internet at home wired thru a Ubiquiti Router and POE Switch and using a MU-MIMO (UAP HD Nano) access point which gives me a 433mbps wifi link to my S9. At home, I also have a 1st GEN At&t Micro-cell which I have left unplugged in case that could be an issue.
If WIfi calling doesn't activate on the work wi-fi then I will grab another SIM card at the at&t store and try again.

Sounds like a plan. I wish I knew why wifi calling is such a pain, I could never get it to provision on my old AT&T uverse internet. I ended up provisioning my Dad's Galaxy S9 wifi calling via the hotspot my S9. If anyone you know would be able to hotspot their At&t phone that might let you provision wifi calling.
1. ATT must have a Samsung Branded ATT Phone's IMEI in the system, so that the features are allowed on your phone.
2. If you have U1, you need to use the U CSC, the U1 CSC breaks wifi calling and all other features that AT&T gives you.
3. If you are able to get root, and can see the system apps,
Under App Folder you need to have
UnifiedWFC
Vsimservice
Under Priv-App You Need to have
NSDSWebApp
WfcServiceV2
3. When you are trying to enable Wifi Calling Service, what happens when you click the wifi calling quick toggle.

Could not provision on my work wifi or my AT&T iPad hot spot wifi.
I went to the AT&T store and got another new SIM card. I then chatted 5 or 6 AT&T Cust Svc. agents and got one that re-provisioned the IMS features and set my IMEI from the S7. They now work on my ATT branded S7, but not on the unlocked S9.
Within 3 second of toggling the WIFI calling feature I get the "ooooops we cant turn on wifi calling, please have an authorized person call.........."
I flashed the HOME CSC when coming from U1 to U. Can I just flash the U CSC as is, or would it be better to flash back to u1 and then back to U with the proper CSC.?
It would appear I had several obstacles to getting this enabled.

LOL Failed again!!!
Flashed U firmware and ATT User Data file. Nothing works. Same message.
What is "...Also make sure you have ATT csc installed......?" I have not been able to find any FW that is AT&T for the U. Every other carrier, yes. but no AT&T.
SO I have flashed back and forth a few times this evening. I did not locate a specific "ATT" CSC file. I did find the ATT USerData file that places the WiFi calling option in the menu like always. So it looks like you can use IMS features on ATT as long as you have the ATT U Version or a Carrier U version variant.
However, If you have the U1 version then it is not possible to use these IMS features on ATT.
I think you can just flash straight to U make sure your sim card is in the phone. If it doesn't work, try factory reset and then flash U CSC
I forget are you able to root to see what system files you have?
You could probably update the phone to the newest U1 buold, but switch out the csc with the U.

All U CSC's include att CSC.
Not rooted yet. Looking forward to it. I'm on U FW now. I couldn't get the IMS features working but I strongly suspect its AT&T. If AT&T
Disabled and enables my IMS on their end then my S7 wifi
Calling works. So into my S9 the SIM goes, it allows me
To check my 911 address and begins to provision but usually
Fails within 10 minutes.
Then, from there on I get the standard "Oops we cant provision" error message on subsequent attempts. Which requires lengthy calls to ATT to disable & enable IMS again. This makes me believe that my S9 IMEI is getting checked and flagged, then IMS is disabled.
Out of the blue I got a forced ATT OTA update today that updated my FW to ARBI, now I see another pending software update waiting. For the new boot loader I assume.
I did try my MINT Mobile SIM and even on the ATT FW I got the IMS features to work, and toggle in the "secret" device info.
I thought I'd give it a go w/o rooting.
My auto-update OFF was overridden and I got pushed the G960USQS2ARF4 to my handset last night.......
US OR US1? Well you can flash the arf4 U CSC right?
So they have you with an ATT S7 ? PM me or telegram me at @Psyscope I'll give you an imei for s8 that will make sure you should have wifi calling provisioned for your account.
These three apps are needed do you have them when you go to Apps?

Sounds like you are running the latest AT&T firmware. If you put your sim into the S7 and call AT&T Customer service and report that Wifi calling isn't working(make sure they hard set the IMEI of the S7 to your account), then re-activate wifi calling on your S7 and then move your sim card into the S9, and try to activate wifi calling.

Could one of you kind folks upload the above mentioned files from an S9 device for me .......... I am experimenting with an S9 port on my S7 Edge and can get WiFi Calling to provision but it still doesn't seem to work on the Phone app itself.
I get all of the activation responses and can even modify my Emergency Location dialog etc. , but no work with WiFi only or poor cellular area.
My CSC Flash and device doesn't have WFCServiceV2 ( just WFCService) and I don't have UnifiedWFC in the app folder
I can get WiFi Calling on Nougat and finally today on Oreo --- but I'd really like to run the Sac23 Port --- it seems the smoothest
Thank you !!!!!

Question --- This is kinda what I've done in the past to get calling features on ATT but I do it by going to my AT&T Business portal (I'm a business customer) and changing the IMEI there. That has worked for me in the past by using an IMEI from a branded store model phone - lol
But I have had some issues ---- when the IMEI that I put in the billing portal doesn't match my actual phone that I'm using then When I go to Phone > Settings > More Settings > Call Forwarding I often get errors or can't set the provisional forwarding numbers (I used Youmail for Voicemail in the past and currently I have been (when Busy, Unreachable , or Unanswered) forwarding to my Google Voice phone number that now has a Google Voice over WiFi Beta program. The other issue is that setting the IMEI to another number messes up Call Forwarding with things like Samsung Gear (AT&T numberSync) ???
What exactly did you get the AT&T Customer Support to do when you called ? maybe its different than what I'm doing in my Business Portal
A different imei has no effect on forwarding, that's related to your sim card. The IMEi if it is an AT&T branded one you call them and tell then to update it to one that's linked to an att branded Samsung phone that is wifi calling capable.
In regards to the s7 edge you would need to extract the csc files from an odin. Then find a custom rom and move the files around. Are you using the an unlocked S7 edge u or F? Because ttkg has a CSC selector.

You know call forwarding rarely works that way. There is the feature
Where you manually setup forwarding.
Dial **21*, followed by the 10-digit number you wish to forward the calls to, then dial #. For example, **21*1235556789# forwards your call to 123.555.6789.
