I have gone thru 2 sim cards, 2 SM-N910A with similar results.

In settings, call, additional settings, it comes up with Network or SIM card error. AT&T has replaced two sim card, one a micro sim, one a nano sim with adapter.

From the keypad, **21*808551999# the error message as attach

The AT&T associate spent an hour with the advanced tech support to no avail.

I have a Nexus 6 and I can access all the above function, so my account is provisioned properly and I'm post paid
[AT&T Samsung Galaxy Note 4] scrtsqrrl:
Did you ever find a solution? I'm having the same problem.
[AT&T Samsung Galaxy Note 4] thanitos:
It's something to do with the phone, as you seem to be aware of, I had a customer come in who wanted to forward his note 4 to his gear s, the same issue happened, from what I can gather it seems to just be an issue with the call app itself, a fix I read but never go to try was taking a sim card from a known working phone that has call forwarding on and inserting it into the unworking phone.
[AT&T Samsung Galaxy Note 4] Blue Puma:
Try stopping the phone app and clear all data. I got a new sim card and then did that and my call forwarding worked. YMMV
[AT&T Samsung Galaxy Note 4] jrtireman:
I have the same problem. I called tech support today and the lady I talked to didn't even know that the gear app could auto forward you calls. She said she would set it up for me on her end. Not what I wanted. I want this 2 high end devices to perform the way they are suppose to before att got there hands on it.

So what I did was, I pulled out my Note 3. Updated to latest FireKat Rom and problem solved.

My note 4 and gear s worked perfectly when I first got them. THEN WE GOT AN UPDATE--------THE ONLY UPDATE.

That's when I first started having this problem.

Not only do we not have root, but now it isn't doing the cool things it should. I'm sorry for the long winded ***** but I shouldn't have to wait for the chance of a possible maybe sometime in the future if everything goes right update that may or may not correct this problem and could possibly inject more issues. I'm sure someone will correct me if I'm wrong.
[AT&T Samsung Galaxy Note 4] Elpidio:
I came across this post:

This is a problem with AT&T. I'm running 4.4.4 Android on a new Note 4 and discovered that Google Voice wouldn't run on the phone. I suspect the issue is tied to AT&T's implementation of their Visual Voicemail.

After spending a few calls with AT&T Tech Support, I was able to get my Google Voice to work by using the Call Forwarding Settings of "Forward When Busy", "Forward When Unavailable", and "Forward When Unreachable" to be set to my Google Voice number. The problem is that the Note 4 has the bug you mention. It's not possible for the user to access the settings on the phone without getting the "Network or SIM card error" message.

AT&T Tech Support can manually configure these settings, but this will only help if you don't change the settings often because a call to AT&T is required. I'm hoping they fix this bug in the Lollipop build.

Be careful when calling AT&T Tech Support, the first two times I called, the Tech Support Agent had no idea that this type of Call Forwarding Settings were configurable.

For the 3rd try at calling them, I got someone more knowledgeable who first reset my voicemail to "Basic Voicemail". This is done in the AT&T system, not on the individual phone. Once that had been done, I then had to "activate" the Basic Voicemail by configuring my box. As soon as that was done, the AT&T rep was able to go into the AT&T system and manually configure the three Call Forwarding options that I wanted.

It was a huge pain to go through, especially because all I wanted to do was use Google Voice which has worked on AT&T Samsung phones going back to my first Galaxy SII.

My phone still shows the "Network or SIM card Error" whenever I try to access the Call Forwarding Settings, but at least I was able to get the Call Forwarding configured for my Google Voice to work again.

I don't know if this info helps you out, but I wanted to pass it along.

Went back to AT&T yesterday, this time armed with my Nexus 6. Got a nano sim. Nexus 6 call forwarding function work. Working sim into Note 4. same crap happens.
[AT&T Samsung Galaxy Note 4] jrtireman:
I just check again this morning, and my Note 3 is working flawlessly. Gear app autofowards my calls as it should and advanced call settings does not show error message. I believe it's a problem with the Note 4 not able to register it's self with the network. If I use another phone it registers fine, call forwarding work as does tethering hot spot. If I try my Note 4 neither wants to work. When I call att they can fix my tethering hot spot but can't fix forwarding. My Note 3 just works by its self without having to do anything such as clear app data or anything with I have tried along with phone reset multiple times. I'm going to use my Note 3 for a while.
[AT&T Samsung Galaxy Note 4] jrtireman:
Used my Note 3 all day today. Everything worked flawlessly. Got home and started my tethering hotspot and no problems. I'm thinking that I'm getting tired of my Note 4. My Note 3 running Firekat is just as fast. The only thing is the camera and the screen is so good. I wish my Note 4 was as, we'll I'll stop there. Thinking about trading Note 4 in for the iPhone 6 plus. I'll still have my Note 3 that everything works perfectly on. I get bored and like to be able to switch up the experience so if I have android, Note 3 would be note 4 but, and the hated ios witch just works and that can be jailbroken with a lot more help because they are all the same device and dose not have individually locked boot loaders. ????? What to do???
[AT&T Samsung Galaxy Note 4] thanitos:
Tethering should work unless you have unlimited data, all mobile share plans from att include thethering, also you can pre-order the s6 on Friday, if I remember what our new Sammy rep was talking to me about, got to play with it for 30 seconds before a customer walked in, the ui is nice and smooth and the new octa exynos chip is suppose to run cooler and it seemed, just for ui scrolling, to sail through it all. I like the look and feel, I want it......

Edit: keep in mind that you'll be in the same position you are now as far as root and unlocked bootloader, if you want these things wait to see who sells the phone unlocked then buy it at full retail and use it on your account. I work for att, I know even the nexus 6, the most close to stock phone we sell has bloat ware and is locked down tight. If I get the s6 it's out right and unlocked.
[AT&T Samsung Galaxy Note 4] jrtireman:
Yes I agree. It should work. If I switch my sim to another phone it works just fine. Everything works as it should, but if I put my sim back in my Note 4 in phone settings advanced settings I get an simcard or network error and call forwarding does not work. Also tethering will fail telling me to call 611 or visit website to register device for tethering. Gear app will fail to forward calls also and I have had problems with network data. If you Google this problem it is a problem with note 4. Some people on the att forums are just hoping for an update soon. That's is not acceptable to me. It worked when I bought the phone then there was an update that was pushed to my phone and now my phone is turned off and I'm using my Note 3. So by the time this gets resolved and I can enjoy my phone it will be old in the world of phone technology. So why should I keep it, hoping it will be updated sometime in the near future which keeps getting pushed back for some unknown to me reason. Don't get me wrong. I love my Note 4 but I want it to work now.

I updated to 5.01, still has the same issue. This is quite possibly the last Samsung phone I'll ever buy
[AT&T Samsung Galaxy Note 4] icexshinigami:
force stop the phone app and it should fix your issue.
[AT&T Samsung Galaxy Note 4] Elpidio:
thanks for the tip, I force stop all three phone apps to no avail.
[AT&T Samsung Galaxy Note 4] icexshinigami:
I know you tried , the dialer codes.

always call forward setting , **21*808551999# (did you make sure it is 10digits? should be , **21*1808551999# if you are in the us. it might be worth a try.

conditional call forwarding **004*1808551999# (busy, rejected, missed calls)
[AT&T Samsung Galaxy Note 4] Elpidio:
sorry, there's one digit missing in my original post

should have been +18085519959

There's definitely something wrong with how AT&T network supporting this phone. I have no problem with my Nexus 6. It's very frustrating but it's something I have to live with if I want to keep using this phone.

Anyways, thanks for trying to help.
[AT&T Samsung Galaxy Note 4] scrtsqrrl:
The upgrade fixed the problem for me. I didn't change anything else besides the OTA update.
[AT&T Samsung Galaxy Note 4] Elpidio:
only thing I have not done is "wipe data/factory reset" from the recovery mode. I'll see if I can back up my data on ODIN
[AT&T Samsung Galaxy Note 4] icexshinigami:
Weird that would have been one of the first things I did.. Assumed you already went that way.. If after all this it doesn't work it seems you may have a defective device and should bring it up with samsung or att for an exchange...
[AT&T Samsung Galaxy Note 4] Elpidio:
I did the "wipe data/factory reset" from recovery and its still the same. You maybe right that the device is defective and since its more than 30 days, either I'll call Samsung for a replacement or claim insurance, however, by looking at AT&T community forum thread, I read that it all worked with N910AUCU1ANIE firmware, when AT&T updated that firmware, all hell broke loose. I'll see if I can have Samsung replace it.

Fix?

I have 5.0.1 on AT&T and was able to solve this by disabling Enhanced LTE Services under Connection>more networks>mobile data. Then checking Call forwarding worked without the Sim error. The odd thing is that I wanted to test that it was a repeatable fix so I re-enable eLTE and call forwarding still worked. I wonder if this fix somehow set a bit that permanently fixed the problem.
[AT&T Samsung Galaxy Note 4] a40dayflud818:
Glad it worked for you. Unfortunately this didn't work for me. Did you reboot the phone after you disabled the Enhanced LTE?
[AT&T Samsung Galaxy Note 4] 53735:
That stinks.... I just went straight to the settings and it all started working.

---------- Post added at 02:01 PM ---------- Previous post was at 01:39 PM ----------

The fix didn't stick for me.

I spent several hours setting up Google voice as my voicemail provider last night and the fix worked fine. I just went back in to Call Forwarding and I now get the error again and I confirmed that the eLTE was still off.

I don't know what's going on.

I'm not sure how I'm supposed to use my phone as a business phone without this functionality.
[AT&T Samsung Galaxy Note 4] i3atUr8raiNz:
Seems the issue is mainly with ATT. maybe ATT should fix their firmwares and roll out their updates. Samsung does not have anything to do with the added features of the carriers. Frankly this has been a problem since before march and ATT doesnt seem to care about their own mess ups.

If you call Samsung about this issue, they will tell you to check your settings to make sure call forwarding is turned on, anything else - call your carrier.

---------- Post added at 04:45 AM ---------- Previous post was at 04:41 AM ----------

So google owns an operating system and the carriers add their own features to it and its Samsungs fault? lol

Samsung is the HP to windows. The hardware has nothing to do with derpy carrier features and its not their obligation to fix it.
[AT&T Samsung Galaxy Note 4] bshrum:
Was this problem ever resolved? It's November now and I'm experiencing this exact problem.
[AT&T Samsung Galaxy Note 4] bshrum:
This solution worked for me. I am currently experiencing the same issue when I enable "Enhanced LTE Services" as described. However, if I disable the enchanced services, I am able to insert the correct forwarding information and it functions as anticipated. A couple of caveats, however: first, I can only change the forwarding information for the "Forward when Unanswered" section. When I attempt to change the others conditions (Forward when busy or Forward when Unreachable, it inserts my AT&T voicemail number). Second, unlike the poster's experience, when I switch "Enhanced" back on, everything reverts back to "turned off."

My question is this, is HD Voice all I am giving up when I turn off Enhanced LTE Services? From the research I've conducted, it seems that all other LTE services are still available? Second question, when the *@#$ is AT&T/Samsung/whoever going to fix this problem? I'm on Lollipop and it seems its been going on forever.
[AT&T Samsung Galaxy Note 4] norbarb:
I had this problem too. I go to AT&T store and tell them about problem. They give me new sim card but this did not help. They get some higher level tech on line and after like 45-60 min everything starts working like should. This is problem on AT&T end.

This could in fact improve the battery status for many people, and if so congrats on an awesome find.

However I do not have a data plan (being the poor college student that I am), therefore do not use push email. My battery life is similar to yours and I can stretch to maybe near 48hrs if there is very very little use of my wizard....

But I am glad we are on the right track :)

[8125, K-JAM, P4300, MDA Vario ROM Development] ND4SPD:
This might be it

I never thought of that. You just sparked something though. On both my HTC Wizard and my old MPx200, which has a full size SD card slot, I remember when I let the power completely drain out that one of the first things I couldn't access was the SD Card slot. I remember being surprised when I couldn't find it.

Nice Job! I'm willing to test with you but I will have to wait for two more weeks. I'm a freshman in high school and have final exams.
[8125, K-JAM, P4300, MDA Vario ROM Development] k2e15:
Good Looks

Good find, I went to do this and it turns out that I had it already set to that :) . Also, when not using your phone turn the screen off and while you are in call turn the screen off by pressing the power button up top. Also, changing the brightness of the screen has really helped my battery out and the fact that I had a bad extended rom. with all that said and your finding my battery has been great. and AHHH finals week here for me.. I feel for you guys.. Mine start tomorrow! BOOOO
[8125, K-JAM, P4300, MDA Vario ROM Development] GldRush98:
You mean you ever made it more then 24 hours?

My Wizard needs charged every night. It's usually chirping by the time I get home from work :(

I do have push email set up though so I attributed that to Push.

Battery life is a bit of a bummer on these devices, but that's why I have a charger at home, in the car, and at my office, haha
[8125, K-JAM, P4300, MDA Vario ROM Development] vettejock99:
Push definitely hurts battery life a bit, and that should be expected, but I have been using that for about a year and I really suspect that it is the combination of the original batteries getting "old" at 1 year and this SD card issue that is causing the accelerated decline. I am still optimistic, and my drain is still not too bad, so hopefully I can just learn to live with "fetching" my attachments to SD only when I need to see them (vs. having Messaging pull all of them automatically) to reclaim several hours to a day of battery life.
[8125, K-JAM, P4300, MDA Vario ROM Development] k2e15:
I can make it 24 hours. Usually at the end of the day say 10 or 11 my battery life is till about 50%. I tested it that night and didnt have to recharge till around 4pm the next day.
[8125, K-JAM, P4300, MDA Vario ROM Development] mattk_r:
I'm sure that vettejock99 is on the right track for some users. My mail program (Xpress Mail) doesn't use the SD, so this wasn't an issue for me - only GPRS usage. When I use the card / applications that access the card, my consumption goes way up. I can see where an app that always runs in the bg and constantly reading/writing to the SD could have a huge effect on battery life, in addition to hardware that's left on - such as Wifi or beam.

[8125, K-JAM, P4300, MDA Vario ROM Development] danik_iceman:
I don't know what u guys are talking about here. I use the Faria Vanilla ROM and my battery lasts for 96 hours, it's amazing! But when used other roms I never had my battery last less than 48 hours.

One more suggestion about the battry life: always close all active programs. They really drain the battery. I tested it luanching 15 applications at a time, and guess what happened? The battery lost 50% in 15 minutes. So, that might be one of the other factors...

Oh, and here is one last thing. The battery drain is also high when the phone network is unavailable. If u leave your phone somewhere where there is no network signal it will automatically try to search the network every n minutes. So, that also causes huge power drain.
[8125, K-JAM, P4300, MDA Vario ROM Development] anichillus:
I wonder if this little SD card thing affecting the battery drain isn't noticed when surfing the net. I set the temp folder on the sd card for IE...just a thought
[8125, K-JAM, P4300, MDA Vario ROM Development] vettejock99:
I dunno, maybe (as was speculated some time ago) the power management is turned on/off by one activity such as surfing w/cache to SD and handled differently when writing attachments......
[8125, K-JAM, P4300, MDA Vario ROM Development] vettejock99:
By way of an update, I ALMOST added earlier today that my consumption was creeping back up again, though it still seemed to be about 20% lower (better) than before. I decided to uninstall TodayAgenda and BatteryStatus from the Molski ROM (the versions integrated into it), even though that would make it less desirable to use. The drain still seemed to be creeping up. I was troubled. Then I realized I had installed Today Commander earlier today to ensure I had an extended rom, which I did in fact have (check that box). Well, I installed it to the SD card - so I uninstalled it. And I removed my SD card. And once again, it appears that my consumption is back down. I have used 1% in the last hour, and that is something I have been unable to accomplish in some time. So.....I could be wrong, but I really think this SD card thing has something to do with it.

I remain hopeful this is it, and there is a way we can fix it, or that I can ultimately leave the SD card in at least, and install apps to memory (as there is plenty of room for my needs) and only pull attachments to SD as needed.

[8125, K-JAM, P4300, MDA Vario ROM Development] Pastamancer:
I thought I remembered seeing a registry hack, or something to that effect, which turned off the polling of the SD slot. I think it was supposed to dramatically improve battery drain times. I'll take a look around for the hack, maybe I'm just dreaming though.
[8125, K-JAM, P4300, MDA Vario ROM Development] vettejock99:
You did, it's out there. Didn't help mine, though. I think that is because the polling does represent some drain, but it appears the actual writing/reading drain is the substantial part.

That is a cause, but as I said, I had an extended rom, not corrupted, and still saw the drain, as have others. So folks need to ensure they have an uncorrupted extended rom, and they need to fix the SD issue in some way or they will likely have battery drain with many ROMs.

Battery problem

I have a very strange problem with my battery. I have 2 cards from different operators. When I use one card my phone work perfect with any radio rom (I leave phone without use and my phone was turned on for more then 5 days). When I use card from second operator, for only one night I loose 30% of battery and I have a lot of missed calls (phone without use was off after less then 2 days). I use uptime meter for stats. Signal strength is similar on both operators.

[8125, K-JAM, P4300, MDA Vario ROM Development] WizardGuy:
I think you've got something....

I just did a test. I've got my system set to deliver both mail and attachments to the SD card. With that set, I pull 122mA. When I changed my system up to deliver to main memory, that dropped to 73mA. That's a 40% gain in power efficiency. To me that's HUGE. I wonder if this varies from card to card. Also did anyone have any luck finding the SD card polling setting.

I'm gonna back off of my statement earlier...I've been watching my MDA all night. And something else must have been running in the backgroud. Ever send I added back attachements to the SD card, the mA hasn't moved from 76. Even with the CPU is being OCed to 260.....more testing to come.
[8125, K-JAM, P4300, MDA Vario ROM Development] vettejock99:
I understand what you are saying. What I am saying is that the corrupted extended rom problem is fairly well known now and yes, that will cause the problem. Some STILL had the problem after fixing the ext. rom, though. I have now told you how to fix it completely. Mine often shows 24-57 mA of usage and lasts almost 2 days with a good deal of use on a 15 month old battery. If yours is fine, great. This is for others that still need to know why some of them have the battery drain.
