Hi everyone,
I just bought a used Note 4 N910C variant from market today. Phone is from Saudi Arabia.
I have noticed I can see a sim card icon or sim signals in notification bar while Sim card is not inserted. On left side in notification bar it says No sim card Emergency calls only.
The phone is on lollipop 5.0.1 stock rom. Phone is not rooted status is 0x0. I have checked the phone by phone info Samsung app it says phone is original.
When I insert sim card calls and 3g work fine signals drop and get stable just like in normal situations. And text No sim card Emergency calls only, get disappear.
Should not I see a round white circle when no sim card is inserted?
This is my first Samsung Android phone. Is it normal or I should be worried?
Im attaching snapshots. Pls reply fast as I have only 2 days warranty by shop keeper.

I guess it's present in all Lollipop build. I'm on 5.1.1 and also experiencing your problem although in a different way.
When I'm at my work area, it's in a building basement with no network signal (at least from my telco), I still get full bar signal but can only use for emergency calls because there is no actual network connection. My phone is getting the signal from another telco.
My temporary solution is to select manually my telco in Settings/Mobile Networks instead of automatic selection.
I still get full bars signal notification, but at the same time gets a warning on the notification bar that my manually selected telco is unavailable.

Its not a problem. Its emergency service. There is some EMERGENCY number that didnt need u to use any SIM. Like maybe Police or Fire department.
Just put it in flight mode

I aim this question at UK sgs owners, so if You are not one of them look away now ! !
I am on tmobile uk and just recently tried to connect to orange (i have terrible reception at workplace) but my phone returned message: your sim card does not allow for connection to network.
And yes i did register myself on signalfest when i received text from tmobile.
I even phoned customer service and they send me new sim card but i still have the same problem.
I google it and it turned out that there is more people out there with same issue. But i couldnt find any solution to this.
So did you have this problem and solved it? or still have? Any sugestions welcome..
Btw i am using darkys 3.0 rom..

I too cannot select Orange T-Mobile manually and get the same sim card error message.
But I did find that sometimes I've automatically connected to the Orange network and see the roaming signal bar icon, so the switch is happening but perhaps only if a T-Mobile signal is lost altogether.
Yeah i got that once or two as well but after conversation with tmobile customer service i know that it should be possible by choosing network manually. Btw what rom do u use? Stock or custom?

Have you got roaming turned on in your settings?
I admit i cannot select t-mobile manualy, however when i want to swap back from t-mobile to orange it lets me.
But most of the time it seems to switch between the two pretty seamlessly.

I'm on Orange and I can't select T-mobile network but it does change automatically. I get the error if I try to manually select T-mobile.
My friend that uses a HTC Desire and on a T-mobile contract can change networks with out his phone giving an error. So maybe it's to do with the Samsung Galaxy S?

I too was on darkys 3.0 rom at the time.
I'm sure I saw a post somewhere that said T-Mobile was adding support to their Galaxy S Froyo release that would handle roaming for the two networks.
I've got an unlocked phone so I do not know if I'll ever have this support.
The network sharing is 2G only at the moment. You have to switch to GSM Only in order to manually select the other network.
I find I have to force the phone to lose what little Orange single it gets around the house so it'll roam onto T-Mobile, and when it's done that I can manually select Orange T-Mobile from the list and it'll stick on that network instead of hopping back onto the terrible Orange signal if it gets a whiff.
Of course this is still a pain because when I go out, to get the best signal and make use of 3G, I have to select automatic and have to do the whole hide-in-a-cupboard-under-the-stairs thing when I get home.
Fun times.
im on orange have no problems selecting t-mobile manually as stated before it works only in 2g. data transfer can be used - edge. 3g and switch without disconnect call should be available early next year. my txt messages can take forever to deliver if im using t-mobile and reply sometimes are not deliverd till the next day.

Installed MM a couple days ago and ever since then I can only get ~1mbps for both dl and ul. Is there a permissions I need to toggle to get the right speeds or is this a known issue? Occasionally I have been getting more dropped signals when on GSM/LTE so I just use global now. Is anyone experiencing the same with t-mobile? Thanks in advance.

FYI, I already did the binge off on the TMO website. Maybe I'll wait 24hrs to see if that helps.

This user toggled it on the phone it appears..
http://forum.xda-developers.com/showpost.php?p=65740322&postcount=7
I already toggled it off since yesterday. But now I get slower speeds then before when on LP. Any users keep their settings on LTE/GSM/UMTS? I used to be on that fine but it seems that it's making me use Global because of frequent dropped signals...

Go to cellular Network Settings and create a new APN Name it T-Mobile US LTE, and only change the properties on these 3 options below, the rest leave as they are. it works for me. I've been getting up to 64Mbps download and 30Mbps speeds...
Name: T-Mobile US LTE
APN: fast.t-mobile.com
APN Protocol: Ivp4/Ivp6
and on Preffered Network type = Global

I have been losing service randomly on mine using T-Mobile. I look at my phone and there is no bars. So I switch back to GSM/lte and signal comes back.
same here. Reported at android central too. Nexus 6 has same problem and solution is flashing lollipop radio I believe
Can we flash lollipop radio for DT2 considering it's not rooted?:silly:
For me it is repeatable to disable and enable Binge and had data locked at 1mbps with it on and good speed off.
That is when I have a connection. Using my old G3 until I see a solution to the dropping cellular connection I'm getting since MM
So I'm not the only one experiencing this phenomenon. If I switch to LTE /GSM, it'll drop and ask to switch to Global. Toggling on/off airplane mode will help, but how will I know when u lose signal? I have friends calling and leaving VMs. I never get the miss call... Just the VM notification. This sucks MM!

When I place a call I get a popup saying:
"Call remain in cellular network. Voice and data charges will apply."
Does anyone know what this is?
I have the AT&T S7 on Cricket.
I only get this when I have WiFi on, so I was thinking something to do with WiFi calling, however I do not think that AT&T even have WiFi calling for the S7 and if they do I have no idea how to turn it off.

Yes I get it on every call. Same as you, I'm using AT&T s7 edge on cricket. I'm curious what it is also.
Same thing is happening on my wife's Galaxy S7 (not edge) on Cricket. But it isn't happening on my Galaxy S7 (also on Cricket).
Do you have wifi calling enabled? Maybe this is letting you know it is not using wifi for the call. Just a guess

I think it's this enhanced lte services, but I'm not sure, I'll test out in a sec
Edit::
Nvm, that's not it either. Turned it off and still saying it
I'm not in the US myself so I don't know much about AT&T. However, after some research the best I can find is with AT&T Dual-Mode Mobile Voice. Is it possible this could be the cause of this message?

So essentially Wi-Fi calling. I know they enabled it for iPhone last year. Possible maybe they are doing testing with the s7/s7 edge
If it is WiFi calling I just want to know how to turn it off.
This popup is annoying and in the way of the buttons.
I get the same thing when placing a call on my s7 AT&T
I have both the S7 and the S7 Edge and get the notification whenever I place a call on either of them while I have WiFi on.
did anyone figure this out .. have the same issue .. def gets in the way
I'm talking to Samsung right now. I'll post if I figure it out.
This is the response I got from Samsung.
It only happens to me when wifi is on but very weak. Probably a holdover from the wifi calling routine that doesn't get disabled when wifi calling is off.
Hi forreros!
First off, my appologies if this has been asked/answered. I've searched the forum for 4g/data connection/mobile data, etc but haven't found anything on it.
My A1 won't connect to 4G networks. I've had it a week and it's hit and miss. It updated to 8.0 last night. Now it's worse. It won't connect at all.
It's the global version. I'm in the UK. I use a Vodafone UK SIM and a Spanish Vodafone SIM. I use the Spanish SIM for data. Roaming is enabled (the APNs that the Vodafone SIM configures automatically for network connections are airtelnet.es and airtelwap.es)
I've done some troubleshooting...
I've found that when I make a phone call while the A1 is connected to a 4g signal the data connection starts working and, for example, Whatsapp messages enter while the call is live or web pages load. But, when I hang up the call the data connection is lost.
I've changed the Preferred Network Type to 3G on the Cellular Network Settings page. Data connection works fine when I tell the phone to only connect to 3G.
But, I switch it back to 4G and the connection is lost. A little "x" appears in the bottom right corner of the network data strength icons in the upper status bar. The little arrows that appear next to the icons also don't work... only the ^ (up) arrow appears. The down (download) arrow stops appearing.
I've also read online that by dialing *#*#4636#* #* you can change the Preferred Network Type. I've tried 3 different ones (the original one chosen was TD-SCDMA/CDMA/UMTS) and none of them fix the problem.
There are some screenshots attached. Can this be fixed? I want to make a decision ASAP. If it can't be easily fixed, I need to notify GearBest and get it replaced/return it.
Thank you.
Ray

Hello biggun3791,
any update on this? I've recently bought 3 Xiaomi A1 phones and on one of them there is same issue you faced. Please let me know your findings.
I got the same issue, asked help for it before but no real help was given.
The most annoying part is that even if you get it working again, that service menu's settings don't stick, it will revert at a random point in time. Planning on selling this phone and just moving on to a more reliable one.
reboot seems the only temporary fix for this...
Decided to go to Canada for the weekend. Seems I randomly lose service, and need to reboot to get a signal again. Everything under Phone Info appears fine, and says I'm not roaming. Anyone else had this issue?
I'm in Verizon in Washington state and my phone has started doing the same thing today. Happed 5 or 6 times today while using YouTube, YouTube TV, Amazon app, and chrome. I was using 1.1.1.1 DNS will change that to see if it makes a difference. Has your problem continued?

I've had the same issues periodically. swapping sim slots has worked for me. give it a shot.
So it turns out my VZW plan was so old, it wasn't giving me the option to roam on other networks (travel pass).
I recently went to Germany and had the issue of having service, but sometimes no data. There's an option that sometimes appears when roaming called Network Operators under Settings > Wi-Fi & internet > Sim & Network > SIM 1 (or SIM 2) that'll manually let you choose which network to connect to. I'm my case my phone automatically connected to "o2 -de" network, and I had to manually choose "telekom.de" network to get calls and data. Unfortunately, I didn't take screenshots while abroad, but this is what it looks like at home...
