I want to check if my sgt 7.7 is in fact locked. I've tried all the possible secret codes for the galaxy tab 7, but they do not work for the 7.7 When I put my sim card in the device it will not connect to the network I need.
Every time is says "your sim card does not allow a connection to this network"
I don't know anyone I can switch sim cards with so I could test. I am a foreigner in Korea. Thanks for the help
How can thw Tab be locket when it'a not available at any network provider yet? Maybe just your SIM is broken... Did you ty he card in a diferent device or a different SIM in your Tab?

Which band and protocols does you P6800 support?, look on the box if it says GSM, WCDMA, CDMA etc... if your network provider does not support the bands and protocols avalible in you P6800 you might need to find another subscription.

Well it says your sim card not your Device so the prob is on your sim card
Hey guys,
So I recently purchased a N900W8 (canadian version) from the internet and it doesnt seem to register to the Bell network. They said it was with the Bell network, but the sim does not work. I also tried a Rogers sim, and it still doesnt register. For both sims, the network bars show up, the voicemail notification icon even shows up, but when I try to make calls it says "Not registered on network". I also just rooted the phone.
So my question is.. if it is SIM locked... how come the sim lock window isnt popping up for either of the sim cards? Since that is not popping up, is there another issue here? The phone is rooted, so would flashing a stock bell rom revert it somehow?
I am stuck.. thanks for all help.

-I have the exact same problem with n9005 version
-check your IMEI by dialling *#06# then pull you battery your find IMEI number......they wont be the same
I think the problem is here
Its possibly a stolen phone?
If it has been reported stolen it won't work on any network in the country it was reported stolen...
Following an Odin upgrade on my i9505 to the official 4.4.2 release my S4 was working fine but, when I rebooted later, mobile data was disabled and when I tried to enable it a message appeared saying “Insert SIM card to access network services”. I rebooted several times and finally I was able to access mobile data without the message appearing.
My SIM card is locked with a PIN and I noticed during the multiple reboots that when the phone first boots up to the SIM unlock screen up it was showing a phone signal, and when I entered the PIN the phone signal disappeared briefly and then came back. I figured this might be the point that 4G is lost, so after I managed to get mobile data working again after a reboot I was able to disable the SIM lock (when I lost mobile data the SIM lock option in security settings was greyed out). Since I've disabled the SIM lock I've booted multiple times without issue. When I re-enabled the SIM lock the problem came back straight away.
Can anyone suggest what the problem might be, and how I can re-enable my SIM lock without losing 3/4G connectivity after most boots.
TIA
samsung s4 9505
samsung s4 i9505
my 3g is not working
no issues with wifi
what could be the problem
2g is working fine(GSM Only)
i am on kot49h rom
I'm having the same problem! I've disabled SIM Card Lock, will let you know how I get on.
Same here
unbranded i9505 using on EE 4GEE
updated and soon after lost mobile data - tried reset & new sim card - nothing. EE are now fully blaming the update and pointing Samsung and HTC customer to manufacturers.
After changing sim it seemed to be ok for a while but now comes and goes. What i have noticed is that my phone will be fine until a restart/power down and sometimes flight mode will fix. Original sim was normal micro sim new is NFC micro sim just for info
this is such BS and samsung are dragging the heels with a fix.
Hmm. I'm with EE 4G as well. I have found that with the SIM security PIN disabled it's more or less OK the majority of the time.
Sorry forgot to mention this was a OTA update
Also noticed that phone will not connect to kies correctly and show phone number as all zero when is connected
can anyone else confirm that?
Hey everyone,
Last night I bought an S7 Edge from a woman on craigslist. It's the AT&T model (SM-G935A). It worked great last night. Phone calls worked, cellular data worked. All was right in the universe. This morning I went to stream a podcast and notice the network was down and there is a circle with a line through it in the status bar. Wifi works but cell data doesn't. I can't make calls or send texts. When I pop the sim in and out it shows that I have 7 new voicemails but that's all. Sim works in other phones. I've tried hard resetting and nothing. The IMEI number is not showing as blacklisted. What can I do? I really hope I'm not out $500...

Sounds like the sim card isn't being read inside the device. You've reset you said? Like factory reset or just turned on/off the phone?

Thank you for your reply. Yes I have factory reset. When I take the sim card out it gives mt the "unable to detect a sim card" message.

Have you tried inserting another sim card from a friend/family member to see of the phone works in reading that sim card?
I'm in cricket myself and use the at&t model but I'm using the unlocked firmware.
I just "upgraded" to Android 7.0 today. My carrier is Verizon.
I'm not sure what's up with it or how to troubleshoot it, however I need my phone back up as soon as possible.
Any help would be greatly appreciated! This is kind of a big deal for me.
Under Dual Sim Settings->Network mode it says the following:
Card 1: LTE/WCDMA/GSM
Card 2: missing or error
However, it's not connected to Verizon's network at all.
I've tried popping the sim in and out, along with restarting the device.
edit:
A SOLUTION HAS BEEN FOUND

I managed to get a hold of a friend's active AT&T phone. Put his sim into slot 1, rebooted and put the Verizon sim back into slot 1 once the AT&T sim was recognized.
This resolved my issue. I just did it so I don't know if it's a permanent fix or not.

I had to remove both my SIMs, put my GSM (T-Mobile) SIM in slot 1...wait for the phone to recognize the SIM...then reboot a few times...then turn it off...put my Verizon and T-Mobile SIMs in slot 1 and 2 respectively...and then reboot. It's worked fine ever since. An old, inactive GSM SIM or a friend's will work fine for this procedure.
But yeah lots of people are having this issue with Verizon SIMs after the update. Really annoying...but it does seem fixable in most cases.

Thanks, I have a friend with a GSM sim. I'll try this out tomorrow night.
@flyer_andy has helped me too with this problem. I had to buy a straight talk sim from Walmart for $50 to get this thing working. I had to do it because i updated on the way to work. Once got to work i had no phone :crying: lol
I had to use my sisters sim card. I turned off the phone, put hers in, once it saw T-Mobile, I took the SIM out while the phone was on, swapped and was good to go. Boots just fine with Verizon data.

Just had a similar issue, running dual SIM. My T Mobile SIM which I use for the mobile data lost its data connection and would not reconnect, showed full Signal but no data. I eventually had to swap the 1 and 2 positions and now it is working.

I hope a phone came with it for that price.
I picked up a SimpleMobile (T-Mobile MVNO) SIM at Family Dollar for $1.
I also had the unexplained automatic reboots after installing B15 last night. It also wasn't recognizing the SIM. It wasn't even recognizing the GSM SIM. I did a couple factory resets and reboots with the GSM installed. I t looks like it needed the radio reset like back in the old A20 days. It eventually recognized the GSM SIM. I then switched out the PagePlus SIM, and added the Tracfone APN.
Everything I looked at seems to be working. Speedtest is showing 5.46 mbps down, but only 100 kpbs up. I think that's about normal for me.

I wrote too soon. I'm back to no service. I'm not sure when service disappeared
I tried putting in the GSM SIM and rebooting a few times.
I put my PagePlus SIM in my old Galaxy S4 to try to have that recognized on the network.
I powered off the Axon and replaced the SIM with the PagePlus one.
It starts up and shows No SIM card, then No Service, then Verizon Wireless for a few seconds, then back to No Service.
It looks like the problem I had when going to A29, but the solution to fix it then isn't working.
Edit:
I did a factory reset with the PagePlus SIM inserted. It came up with phone service. I had to add the TRACFONE.VZWENTP APN.
It then showed an LTE connection. I shut off Wifi, and it started to load a web page. It then stopped loading, and went back to No Service at the top.

Do you have a Verizon phone that you can stick your PP SIM into, to verify that the SIM correctly works?
i'm having similar data connectivity issues with my Axon 7 and at&t after the Nougat update. Axon 7 is rooted with B15, using 1-sim and a microSD, here's my issue description
-
day 1-3: 4G/LTE connection working, no data issues
day 3: 4G/LTE connection working, can connect to web pages, but could not connect to Google Play, Youtube,Google News and none of my 3 Exchange email accounts. Switch to Wifi and no issues connecting to any Google Play, Youtube,Google News and none of my 3 Exchange email accounts
day 4: Same issues as day 3, factory reset manually reinstall all apps, email accounts, etc. after a couple of reboots, could not connect to Google Play, Youtube,Google News and none of my 3 Exchange email accounts. tried Lineage OS and 4 hours after fully setup, problem is back. with Lineage OS, signal bars showed no signal with each connection attempt and after 30 seconds, connection timed out and signal bars would return.
Troubleshooting:
- swapped sims from two working devices into the Axon 7 and same no-connection/time-out connectivity issues with Google Play, Youtube,Google News and my 3 Exchange email accounts
- all 3 sims tested work in every device except the Axon 7
- at&t re-provisioned my account and confirmed there are not issues on their end.
i'm stumped. any suggestions would be appreciated. otherwise, i'm in my 14-day window and my have to return the device. thanks.
When the verizon sim is installed, is global mode an option under settings, network settings (not the 4636 menu)? If so, try that.

I should have been clearer. The PP SIM works fine with my old Galaxy S4. I miss a lot of incoming calls with it, but that isn't configuration related. It's always done that.
Thank you for the reply.
Can't recognize ATT sim either..
Pull the sim and factory reset, reset network settings also. Then put the sim in and keep factory resetting until it's recognized. Took 3 tries on my phone and 5 on my friends.

Are you all able to use HD Voice & video calling with the native dialer on the Verizon network? Some phones have an option under settings called 'Advanced Calling'. This is where you can turn on HD Voice & Video Calling for Verizon.
