Guys help. Noob here.

Hey guys, i just received my Sony Ericson Xperia Arc S from japan (docomo). I just boot it, everything is fine until I insert the sim card, Im from Philippines and I'm new to android phones so i can't tell if this phone is unlock to all sim. I tried to scan the network and it detects all of the carrier in my country but i always prompted to this after i choose my carrier "your sim card does not allow connection to this network".
Your response will be much appreciated.

try with some other carrier sim cards on your phone...

Your phone does not have to be rooted to be unlocked. A carrier unlock is totally different. it allows you to use any sim card in your device. Rooting gives you access to the hidden file system that actually runs the phone.

I think you should contact your cell provider to replace the sim.

first try it with a different carrier's sim. if its working then ask your provider for a sim replacement. if its not working then your phone is probably carrier locked. (of course if reception is fine at your location)

No service in israel ...

i have sm-n910v and now i am in Israel , when i insert the sim i get (sim card is not from Verizon)and no service i have the (N910VVRU1BOAF ) on 5.0.1 is there any solution to get this phone work please i try to use Debloater TO STOP the sim verification but i get this error (your device dose not support block mode) any solution
i am thinking to downgrade it back to 4.4.4 as i know this baseband can be downgrade ,,, any solution before ????
i don't have Verizon sim to activate ....
not :- i have checked that the band of phone work on the provider (golan telecom )

Should work fine just make sure you chose lte/umts /gsm
Also Debloater works well regardless of the warning message.. You still can use it to block the sim activation wizard

Use Verizon note 4 on AT&T

I got Verizon Note 4.
Verified that it is unlocked. Not stolen. No contract binded from Verizon store and through phone (Clean phone)
Android Version : 5.0.1
Location: Las Vegas
Insert AT&T sim card. No signal.
Change APN setting following the information on AT&T website. Still not working. No signal.
At&t store rep. said I need to l unlock the phone ( I already check with Verizon via phone and store)
Verizon rep. on phone said: I should be able to use the phone with At&t sim card
Verizon Rep. in store said : Galaxy note 4 won't work on AT&T. It needs to be rooted by an expert. Only Galaxy S5 or later version will work.
I searched websites and many say that they are using Verizon Note 4 on AT&T network (At&t sim card)
I just need to use phone and text message. No data needed.
Anybody can help me?

I was able to use SIM from AT&T before yesterday, but after trying to update the firmware using Software Upgrade Assistant tool on Windows 10, it's now stuck at 'searching for service'.

Did you change the network settings from global to lte/GSM?

I am reading this. Maybe a solution.

Did you try to insert a different carrier sim card and entering the unlock code?

After reading post i see you have a att sim sim on verizon phone. This could be a problem as verizon and att dont play nice. Stupid question is did you actually pay for service?

Yeah. Me either.

Did you do a factory reset after software update. Usually helps. Also mess with APN settings. Reboot after changing APN.

Problem solved.
Changing APN settings and reboot did not work. I just inserted the Verizon SIM came with the phone and made a phone call. Of course it's not activated, so I hang up when it reached Verizon automated system. Guess what, now SIM from Lycomobile works. H2O Wireless SIM also works. It means that it now can work with AT&T and T-Mobile network.

I'm in a similar boat as you (4.4.4 on Cricket Wireless, wanting to upgrade to 5.1.1). I just want to make sure I understand what you did to restore service:
1. You had phone working on AT&T with an older Android version (KK?)
2. You upgraded to a newer version via the Verizon upgrade tool (I assume 5.0.1 since 5.1.1 is not yet available via the tool)
3. You lost AT&T service after upgrade
4. You were able to restore AT&T service by using an inactive Verizon SIM and making a phone call
Is this correct? TIA

Mostly, except that I tried to upgrade from 5.0.1 to 5.1.1, but found that 5.1.1 was not yet available via the tool, but the process of installing the software on windows 10 and maybe I also used the Verizon SIM during the process which might have messed something up. I updated the firmware to 5.1.1 by downloading the zip file in a thread here and flashed it through recovery. The network connection problem was then solved by making a phone call with the SIM came with the phone.

I just updated via the Verizon tool (BPA1 finally showed up) and it was, surprisingly, perfectly fine. I first backed up as much as I can (via Smart Switch and Helium app), then pulled my mSD card, left my SIM card in the phone, and proceeded to update. After the first boot stuff (app optimization, etc.) I soon saw the AT&T sign in the notification bar, and I was able to make a phone call without doing anything else. With all the reports of SIM card locking after updating I was worried that I might run into the same issue, but was pleasantly surprised that I didn't. I had to re-enter the APN setting as the upgrade seemed to have removed it, but after re-adding Cricket's APN I was able to get cellular data as well.
Thanks again for your help

You need to access the hidden menu and change your radio and modem protocols. There's a forum on XDA called domestic and internation sim or network unlock for spring but should work the same on verizon

fyi, i got my note 4 working on gsm using 2 different freedompop sims-the at&t lte sim gets lte via band 4.
the global sim based on t-mobile did get hpsda+
just change the apn

I need help on samsung note 4 N910v

My friend brought an original refurbish Samsung N910v android version 5.01 which was working with GSM 2G if not 3G until when I tried to update to new version android v6.0.1. In the menu>setting>about when I checked first before anything it showed me N910 F v5.01 but in boot mode Odin it was N910v.The problem started when I just typed *#9090# the phone immediately started reboot loop. I have managed to unlock the boot loader and root the phone installed custom rom version 6.0.1 by Paul Pizz rom VRU2CPJ2.r-1 but still can not have 2G or 3G GSM network. Please help to revive the phone again whether it meant to go back to 5.0.1 that would work with gsm cause am full stack now.

Have you checked to ensure you have the APN information in place? I have a Galaxy Note 4 N910V now (just got it a few days ago) and when I put my T-Mobile SIM in it from the very first time I have to manually put in the APN data - on custom ROMs it's usually picked up and there automagically but not always so, my suggestion is that you check to make sure your APN information is currently there as it should be.
Settings - More - Cellular networks - Access Point Names - make sure the one you need to be using is selected and if it's not then you'll have to put that info in manually and save it.
As for the actual model number, take the battery out and see what the model number is on the sticker in the battery compartment area - if the sticker isn't there then it could be a device that someone has done some experimenting with because that info can be changed. The sticker should be there, of course, but sometimes people take 'em out when they're mucking around with stuff, who knows.

The APN will be your network. Are trying to use Verizon? If so, you should have a spot to tic the VZWINTERNET. If not, then you have a sim card issue.

ziggy the how do i sort out the sim card issue ,Since phone says this sim card is not from verizon

Is the sim from verizon? If you have a good account go to a corporate store and have them give you a new one. It's free.
Also, what are your APN settings and I will compare to mine. Everything works on mine.

the fone I have came from china ,am in Africa and remember I told you it was working woth N910f firmware version 5.0.1.All am asking is there anyway I could make this fone work again on Gsm network, cause all it says after re flash is the card is not from verizon

I now rooted this n910v android version 5.1.1 still no network, am in Africa where there is 2G&3G GSM network, how would I make this fone to work again with the gsm network now that I rooted. On the network bar I get a circle with a cross ,how to make this work

- N910VVRU2CPJ2_FullFirmware_NoAboot<--- Full Framework with no aboot so you will not re-lock bootloader, but will unroot and restore back to 100% stock. once your on the full stock check if your connections are working fine, if they are then install custom rom, otherwise change the sim card

go in settings, connections and select network mode to global, should be fine

Question SIM not working after EU V3.23 Update

Hey guys,
yesterday my phone got updated to the 3.23 Version. Since then my phone is getting no signal to my provider nor mobile network.
I tried WIPE USER DATA which also doesnt work. The sim works fine in my iphone xs...
I also tried to manually apply APN settings.
After i plug in the SIM card it asks for my pin. I enter the pin and it unlocks the SIM but no signal.
I only get a Question Mark at the Status Bar.
Do you guys have any similar problems?
Greetings from Germany

then maybe EU problem... any EU users here?

I updated yesterday & have signal (in Poland).
I suggest that you try to manually switch the network type in settings, to 4G/3G/2G.
