Well I bought a Samsung Galaxy note 4 Verizon about 1 month ago. While i was using the phone it had kitkat 4.4.4 and i decided to upgrade it to Lollipop 5.0.1 three days ago. Yesterday i started to have a problem, in the notifications Menu it says "No Service" "Selected network (Movistar) not available" but then i look for networks and I do get Movistar but can only use my data on it not make calls or text messages. Can someone help me? My first post...

Its a unlocked TMobile samsung galaxy S2 (SGH - T989) from US which I am trying to use in India. I had bought it from t-mobile as part of a 2 year contract. After completing my two years contract, I got the phone unlocked from t-mobile before coming to India. The phone worked fine for first 15 days here in India but stopped working since then. I have tried many different SIM cards from different Indian mobile service providers. These SIM cards work perfectly fine on other handsets . *#06# shows correct IMEI which matches with what is printed on the back side. Phone shows signal towers with varying signal strength. I could see the signal towers even after disabling Wifi and location services but when i try to make a call, it says "Not registered on network". Wifi, if enabled, works fine though. When I try to select a network operator from Mobile networks menu, it does say registered to network occasionally but mostly it fails to connect to any network (i have tried both manual and automatic selection) but even if it says registered to network, when i try to make call, it says not registered on network so I am not able to make any calls at all. I have tried factory reset and upgraded to JB 4.1.2 (radio: UVMC6) but problem still stays. Please help me.
Did you try entering the correct apn ? Similar thing happened to me but i took it to the sim card company and they entered the apn manually and it worked.

I did try APN but I believe that is for GPRS/EDGE and 3D and these will take effect once cell network is established.
Last night my AT&T branded SGH-I317 phone, which I've been using on Straight Talk for a long time now without problems, decided to do an OTA update. It looks like it put 4.4.2 Kit Kat Build number KOT49H.I317UCUCNE5 on there with Baseband version I317UCUCNE5. When I woke up and this update was complete, I had no mobile data. No amount of fiddling with my APN settings brings it back. Device status states that my service state is "In service" and my mobile network state is "Disconnected."
I'm really not sure what happened, but if I had to guess, the new radio firmware killed my sim unlock that I did a long time ago to get this phone to work on Straight Talk. I can still make calls though, so not sure.
Is this a known issue? I've been searching for hours and haven't come up with anything significant. Anybody have an idea how I can get mobile data back?
This is my first post,so please bear with me.My T-Mobile S3 lost all its calling,texting,data connection 3 weeks ago.My 4GLTE symbol disappeared and the signal strength bars constantly go from 3-4 bars to no service(circle with a slash through it) It was a T-Mobile phone that I swapped over to Straight Talk about 2 months ago.I called ST and they said that T-Mobile had put an IMEI block on it,so I called T-Mobile and they checked and said no such block was in effect for my phone.I called ST back and they said my SIM card was the problem and they shipped me a new SIM.I got it today and called and activated it.I can receive calls every now and then,i cant ever dial out because it says not registered on network. I noticed that even n ow with the new SIM installed,I still don't have 4G/LTE symbol ever. My phone is rooted with Root66 and has a TWRP recovery.Can someone please help me???
Not registered on network usually means that it has been blocked. Try a sim from T-Mobile if you can, to see if it will pick up service
Hi guys can you please help me with this?
I bought my note 5 off craigslist and it was currently on G920AUCU1AOJ1
This security notice wouldn't stop notifying me ect common error I guess when they first came out. Solved by getting app disabler.
I really wanted to get the marshmallow update, I tried OTA says it was fully updated.
I then flashed it too N920AUCU2APB2 Then I noticed it was saying emergency calls only when I tried to call someone. I just continued to flashing to marshmallow.
Now I can't even find a downgrade firmware back to my original state to get the phone to even work again! everything else works but when I looked in to about my phone
SIM card status it says Network Unknown, signal strength -113 dBm 0 asu. Mobile network UMTS, Service state out of service, Roaming Not roaming, mobile network state Disconnected.
I believe the guy I bought it from knew all this and that's why he took it back to a stock firmware.
Can someone please help me out with this? I can't even find the stockware to take my phone back! Either I would and the links broken or its for a different carrier.
I have an unlocked at&t note 4 being used with t-mobile. Recently the internet connection drops as soon as a call comes in and comes right back when done. i checked with t-mobile and they say on their end their service supports talk and surf at the same time.
Is there an update or setting that got switched on? running stock 5.1.1
