Calls and text not working on AT&T? - G3 Q&A, Help & Troubleshooting

Hey guys so I woke up this morning and noticed that I can't make calls or send texts. I can't even run those codes through my dialer to check on my data. Which is weird since my data is working perfectly fine.
At first I thought it was my apn settings that got all wonky but I put my Sim in my Optimus G Pro which is complete stock and I get the same results. It's currently Sunday and the AT&T store is closed. Do you guy's think it's a problem on their end or would it possibly be my Sim card that might have gotten damaged? I almost never took my Sim card out, it's stayed in my g3 for most of its life. I haven't taken it out for maybe 5 months now and everything was working perfectly yesterday.
I would just like to hear your opinions on this please.
Edit: All working now, guess it was a tower issue.

att sms no longer working

somehow...my gnxs no longer plays nice with att sms-outbound. after an hour with att help desk i got nowhere. they want i reset smsc # but i can't find where ics has the setting buried. when running *#*#4636#*#* it is clearly missing the number but i guess i'm incapable of getting the number to stick. i'm told to set the att sms call through # to 13123149810.
funny that since day one running my existing sim in the phone i have been sending texts no problem. do not know if related but bounce-back sms started after i flashed a new bake of Ir4 and also loaded up Widgetsoid2.x over the last 12-hours or so
any suggestions?
Put your sim back in your previous phone that AT&T saw you have last. like when this happened to me the last phone they knew I had was a iPhone 3G... since I bought the N1 outright and then went to the Nexus S and then f'ed up the settings on my own... I placed my sim card back into my iPhone 3G since i still had it and sent a test message and got a message back and then went back and put my sim back into my Nexus S at the time and I was fine again... f'ed up a little but it worked... try that...

good solution. worked. fired up an old Tilt 2 and re-set smsc # which provisioned the att server and then replaced sim in gnxs and i can send sms again. it is amazing that att level 2 android help desk couldn't figure this out. thanks!

[Q] Very Weird Issue

My wife and I have an ATT OGP. Starting yesterday, she was not able to get any kind of connection on her phone. The phone would not register on a network or anything. I put my SIM in her phone and everything was fine, so we assumed her SIM was bad. She went to the store this morning and they found that her SIM worked fine in other OGPs in the store as well as the guy that was helping her. Their test SIMS and several other SIMS they used worked in her phone. Long story short, her SIM will work in it seems any other phone but her OGP, and everyone's SIM will work just fine in her phone. Why would the OGP not take that specific SIM, but every other phone will?
They are replacing it, but I was just wandering if anyone has seen anything like this.
That's a first of hearing that!

Cannot connect to wind!?

Hey guys, I have a Galaxy S3 from Wind (T999V) It worked perfectly fine for over a year. After the warranty was up, I decided to root since I didn't really have much to lose. I flashed everything from, CM to Illuzions ROM. Everything worked great. One night I was on the phone with my girlfriend, we got off around 12. I put my phone on charge and then the next morning I woke up around 6:30, checked my phone and all was still good. Then after taking my dog for a walk, I checked once again at 7:30, and I was not connected to wind anymore. I turned airplane on and off, hard resets, unroot and back to stock. I have actually tried everything. Spent hours upon hours with wind tech support, and they even gave me a new sim. Went to a warranty center to pick up the sim and even with the new sim my phone wouldn't work. While there, I asked if they could try the sim in a different phone, and it worked in the other phone, so I'm pretty much certain its a hardware issue now, though it worked perfect for over a year,
Can someone please help me, PLEASE?!?!?!?!??!?!?!!?!!?!?!?!?!?!?!?!?!???!!??!!??!!??!?!?!?!?!?!?!
P.S. Already tried to manually select a network, All it will find is Wind Away. I put in my friends SIM from bell and it got bars, connected to the network, just wouldnt let me place calls because it is locked to wind.
Sounds more like an account issue to me. Find someone with a wind phone, and try their SIM in your phone. The way it sounds to me after testing with the Rogers SIM, is that the device is fine. If it were hardware your friends SIM would have done nothing more than yours.

Yea, but when I went to the wind store to get my new SIM, they tested it out on another device so I know the SIM is working, so wouldn't testing his SIM on mine be the same as testing my SIM on any other wind phone?
No idea. All I know is you mentioned that when you tried a Rogers SIM it seemed like it worked, or would if unlocked. Only way to know is to try another SIM on your phone. Could be an account issue. But if it appeared to work as expected with his SIM, that tells me it's probably not hardware.
Maybe a wind tower is having problems....

Note 3 Missing Calls/Delayed Texts

I've searched around but i can't seem to find a solution. My note 3 is missing calls, and not notifying me. When someone calls it rings on their end but my note 3 doesn't seem to be getting the signal, but i get their voice-mail a few seconds later. This is just ridiculous, how can a $700 phone fail to complete the most basic function of a phone.
Now, let me just say that I have excellent coverage in my area, and my previous phone did not have this issue, i'v also tried factory resetting and even exchanged the phone! if anyone else is having this issue, please share.
Again, this is my second note 3! i exchanged the first one for the same issue, but its happening again after the exchange! This is really frustrating.
Yup. I get delayed and duplicate texts (at times) from the sender. Also, 1/4 of my texts don't go through. This is also my second device and I don't see a solution. Sucks when you rely on your cell phone for work.
I'm heated

Even though you have good signal, it still might be a service issue. For about a month, I was having the same issue with my s4. It went away on its own, so I'm assuming it was service related. It also wouldn't hurt to try a new sim card.

I read that some people resolve the issue by changing to WCDMA from the defaulted LTE

I'm with Towle in that it's probably a service issue. For the last three weeks, I've been going back and forth with T-Mobile because suddenly two of my kids can't send texts or get caller ID on their S3s. And when I first received my Note 3, I didn't receive any mobile data for a week. They've had me swap SIMs, rebooted countless times, had the engineers 'reset the rate plan' a few times, and we're still having problems. I'm in the NE Illinois region, if that's any help.
I haven't rooted my SM-N900T yet but I have noticed that (in my case) wifi seems to be related to this issue. When I activate wifi calling or turn wifi off completely I'll get a stream of messages.
I have been having the same problem. Glad to see its not just me but hope we find a fix. I also have a issue keeping LTE although im less than 1/2 mile from a tower. If I toggle wifi I get it back but loose it within a couple of hours and then repeat the process.

Try going into settings, wifi, hit menu, advanced, and uncheck Auto network switch. This will keep it locked to your signal rather than switching back and forth needlessly. This resolved my similar issue. I also unchecked Always allow scanning.
I understand what your saying about the network itself affecting the signal, but this just happened when i switched to the note 3. Everything was fine on my previous phone.
It seems like its happening less frequently now, but i do still miss calls and i have to constantly check my voice mail to check.
I've had the issue with missed calls, but it has mostly happened at my office where it's spotty coverage. Also, the duplicate text issue is super annoying. However the issues are very minimal now on second phone with the new ISIS SIM (comes with phone).
I actually posted about this last week... I thought I was the only one http://forum.xda-developers.com/showthread.php?t=2547762
Here's a copy and paste of that post along with update:
So I switched from Sprint to T-Mobile about 2 months ago...
Ever since I switched, I have been having massive issues.
The first issue happened while on the stock ROM 3 weeks in. For 2 hours, my phone didnt ring or receive any texts. When I made a phone call after those 2 hours, I got a dozen texts in and a few voicemails all in the span of 1 minute. My friends had been trying to call and SMS me for those 2 hours and my phone only received them when I "woke" it up with that phone call.
Then last Friday, I had 3 different people tell me they had SMS'd me and I hadn't received those texts.
Then today, I sent a simple MMS text to about 20 people wishing them happy Thanksgiving. Everyone on T-Mobile got them. On AT&T and Verizon phones, most of my friends got blank texts. I tried to resend it, but they either received a tiny version of the image or another blank text.
On top of ALL this, I am getting duplicate texts from people randomly.
It can't be the phone, as I had to replace it under insurance a week ago (when i accidentally cracked the screen). And it can't be the ROM, as this has happened to me under stock ROM, DarthStalker, and Wicked.
I called T-Mobile and entered a ticket last night about this. This is a HUGE issue. While I love my phone and the fast data speeds, missing SMS (and phone calls) is a game ender.. On the first night I had this happen, I had a date waiting in my lobby for over an hour thinking I stood her up when I didnt respond to her texts. I've gotten in similar trouble with other missing texts.
Update:
So on Friday, I called T-Mobile to tell them about further issues. They told me my ticket had been closed. I immediately told them to re-open the ticket as they hadn't actually fixed anything. On Monday, three of my incoming calls were randomly dropped (with full signal showing on my phone).
Today, I got a call from T-Mobile. He said there had been an issue on Thanksgiving with the network, which is why my MMS didnt go out. But for the dropped calls and missing SMS, after telling him these problems are happening even with WiFi off, he said I should go to the T-Mobile store and have my SIM chip replaced.
This is REALLY frustrating.

The wife and I are having the exact same issue. We both got the note 3 last week. Interesting enough it only happens when wifi is on. I tried with and without wifi calling.

I took off Wifi calling because it seemed like it was causing issues for me with calls/texts. I haven't gotten a duplicate text in a few days now. But I definitely had similar issues to everyone on thread. We definitely are not crazy.
I know right, I called tmobile, they said the usual...but then the issues stoped? Wierd

[Q] Unable to detect sim card

I bought my note 4 on launch day. Ever since then I've had an "unable to detect sim card please restart phone" error. At first it only showed up once every few days, but now it is getting more and more frequent and is happening multiple times a day. After reading starting the phone works fine for a while. I've done everything I can think of (pulling the battery, pulling and re inserting the sim, cleaning the sim), but nothing helps. Anyone else having this issue, or know of a solution? Thank you.

I am having the same issue. Not sure of a fix yet but it is getting more and more frequent which worries me.
Same here. :sadface:
Same here! Anybody contact Samsung or Sprint about it?
Same here!!!
Just got my note 4 from Amazon.com. I had been reading about the lte to 3g call drop issue, and someone posted using there sim the card from the phone they were replacing fix this issue. So I put mine in from my s4 before i even turn it on for the first time. The phone worked, but was unable to connet to the 4g (lte / spark ) network. 3g worked fine. I got the message you all are getting (no sim, restart device....). It would happen like every 10 minutes. Once I put the sim that came with the phone in , all my problems went away. Long story short, you need another sim card.
I just called sprint and they are sending me another SIM card. It happens from time to time, but they did tell me if it continues, I can get it replaced for no charge.

This happened after my sim card swap. It would say "network did not respond in time" then "could not detect sim" then phone would reboot. It did it three different times. Then connection became stable and has not done it again. Not sure if these issues are the same as whats happening here. Just posting my experiences.
I actually bought 2 N910P. I planned on making a little extra money by selling 1 of them, but didn't count on the N910P being so easy to get, so I've held onto the other one for a back up until I found a ROM that I wanted to run on it. Well, I found a awesome ROM & booted up my 2nd N910P & got the message you have all mentioned. I thought it was strange, so I rebooted & got the same message again. After doing this a few times, I thought why not take my SIM card from the 1st N910P & put it in the 2nd N910P. I still got the same message after doing this, so I swapped them back before it messed up my primary SIM card. @Yoshi1221, please keep me/us updated if the new SIM card works for you. Has anybody else got a new SIM card? Also, after installing the 2nd ROM that I was trying out, the fingerprint scanner stopped working. I went back to stock & it still doesn't work, so I made sure that I did a full NANDROID backup on my 2nd N910P in hopes that once I get it working & the fingerprint scanner stops working, I can go back. Anyone else had this trouble?
Edit: I tried to activate my new GN4, but the DEC & HEX numbers were not recoginzed by Sprint.com. So I went into chat & they informed me that it had been turned over to technical support & to contact them again after 24 hours, so we'll see where it goes from there.
Update: Chatted with Sprint & the lady activated the SIM card after giving her the number. Hope this will help out. Just go to Sprint.com & click on the chat button.
Looks like new SIM card is working, but just got it today, seriously had to give up an arm and leg in order for sprint to send me one, but so far it looks like it is working, but just got it today, lol

Cool, glad it work out for you.
Also found out from a supervisor in the U.S that sprint is now selling GSM phones now. If you take out the SIM card and only receive 3G, you have a GSM phone, if you take out the SIM card and have spark/LTE, you have a CDMA phone

I had this problem. Sprint sent me a new sim. Fixed the problem for a few weeks but it has returned. Anyone ever get this figured out?
Sim card not found
I had forgetten about this error. Saw that someone suggested a piece of paper between the sim and case cover. I had this happen with a phone I got off a forum. Sent it back and got a replacement. The paper, no matter how thin or thick may or maynot work, and only for a short time. Changing the sim might not work either. You may just need a new phone. I went through all with a s4. Now my note 4 is doing it. I thought it was my recently deceased (July 4) mother was messing with me. One more errand to add to my list for today.
same here?
help plz
