Need some help.
When installing the SIM card of Kazakh operators no longer connect to Wi-Fi. Why is this a problem? Only hard reset helps.
Because you cannot access multiple data connections at once. Even phones do this. If you go to wifi, 3G gets disabled.
If turn off 3g or remove the SIM card, Wi-Fi does not work anymore. Helps only hard-reset

When wifi don't work anymore, does it show enabled or disabled and are you able to change it to enable.
if it is enabled, disable reboot, then enable and reboot.
if it is enabled..? will it disable or uncheck..?
Wi-Fi enabled, and after a reboot is enabled, but when installing SIM card will no longer see Wi-Fi network.
At Motorola Atrix is solved by some script blocking line settings.db wifi_country_code US.
Anybody can do this for the A501?
Normal behaviour on my A501 is this:
When I switch WiFi on 3G automatically disables, when I switch WiFi off 3G enables again.
Are you running a custom ROM? if not, and you're still on stock you might have either a problem with your SIM card or a hardware issue.
Have you tried someone elses SIM in your Iconia?
Wait... You're not trying to insert the SIM with the device turned ON, are you?
Silverblade.nz, I tried the stock firmware and taboonai and from fguy. Set 3 SIM cards from different operators.
FloatingFatMan, Yes, i insert the SIM with the device turned ON. Tablet requested reboot. After rebooting, sees only the 3d
Somewhere on the internet i read that if insert a sim anoher country, wi-fi is enabled again. but i dont have sim another country (

Bad idea. There's a REALLY good reason why almost all phones have the SIM socket under the battery, to stop you inserting your SIM with the device powered on. Try turning your tablet OFF before inserting the SIM.
This method does not work. I think the problem in a wireless network driver.
No solution? I have the same problem

I have to agree.
The operating instructions, specify, DO NOT INSERT SIM CARD when the tab is operating.
This will probably destroy the sim. I hope not the data recepticle.
At this point, I have to ask, are you rooted an running a custom ROM? Or is this a factory ROM?
Your tablet, is not different from mine (I live in moscow), and the Beeline or MTS network, should switch between 3g Sim data and wifi automatically.
I would do a factory reset (if you have a stock factory rom). Insert sim and sd card with the tablet off. Reboot.
Iconia A501
Same problem with my tablet both for 3.0.1 and 3.2. None of above help except factory reset which is painful.
Anyone found a workaround???

Again, do not insert a Sim card, with the tablet running.
I would do this, under a fresh 3.2 install.
With tab off, insert sim card. Reboot. You should have 2/3g access.
Then, do your factory reset. DO NOT REMOVE THE SIM. Leave it there.
After you are running, if you need to, Enable your Wifi and do your update to 3.2.
Honestly, nobody is having this issue, except for people from your region/country. This tells me, it is something to do with either your Network provider, or Wifi settings in your region.
It is impossible for us to fix this issue, as we do not live there.
Who is your Network (sim) provider?

I have a unlocked Samsung Focus v1.3 with Mango update. I am a 3G SIM card (Airtel 3G).
Sometimes when I am trying to enable data connection, phone is refusing me to do that. The setting shows data connection ON, but 3G symbol on top does not appear.
This happens even on multiple retries and when signal strength is full. Using the same SIM card I am able to connect to internet using my older Nokia phone without any issue.
The only solution I have been able to find is to soft reset (restart) the phone. Then it is able to enable data connection. I also think that this issue appeared after I updated it to Mango. With stock NoDo update it was working fine (though I had this phone only for 2 weeks before updating to Mango).
Is anybody else also facing this issue?
yes i am having a similar issue with my focus, it is unlocked for use in the UK on o2 but when ever i turn my data on it says its connected i have the 3g symbol and everything but when i try and go on the internet it has not connection to resolve this problem i delete my apn and enter it again but that dose not work sometimes and it is really annoying
many thanks if you can help me
^^ Thanks for confirming that I am not the only one facing this issue. But still it is weird that only a few might be facing this issue.
I am still trying to find out the exact solution, so whenever I find it I will post it here.
APN settings? is the sim card for that device originally?or carrier specific"?

I have used correct APN settings for my Service Provider. Hence on a good day, I am able to connect to Internet. I have also confirmed the settings from CC.
But as I have described earlier, sometimes phone just doesn't turn on data connection. This happens without any specific reason. On other forums too people are reporting the same behaviour.

That has nothing to with problem I am facing. This setting for radio is for FM radio and not for mobile radio. You might face the issue again. Sorry but that's the truth!
did u try another sim card?
A friend with same data plan?
And another operator sim?
When i changed wifi to data it came to me, there was a app for that first it closes wifi then open data connection. For wifi again, first it closes data connection and opens wifi.
I got same problem. Using unlocked focus with airtel connection india. On a good day the phone will work with gprs/3g just fine. But occasionally connection drops and the phone won't reconnect. I have to manually restart the phone to connect to internet once again. Any solution for this? I guess people in US aren't facing such an issue..
I have the exact same problem. This problem arises only on DATA connections!
Using ATT Samsung Focus v.1.3 on Idea Cellular Sim Card in India
I have no signal and under the notifications bar It says "Selected network (T-mobile UK) is unavailable. So I thought let me change the sim, I did it still doesn't work. I checked and cleaned the sim card hole. Didn't work, I tried to set it manually under networks and select network, it didn't work also I checked my IMEI but my IMEI is still shown but my signal is -113dBm so what's the problem? I even flashed and factory reset to stock still the problem persists. Right now I'm using Kyrillos rom 10.5. Thanks in advanced.
Might sound stupid but try the Sim in another phone?

I've tried 2 sims and they both work in another phone. Seems like it could be a faulty sim card slot. Guess it's time to throw out my G3 had it now for over a year.
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

no issues with wifi

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?
There is also software based bug for network mode. I have personally experienced this i.e. network mode doesn’t change in reality even if I select 3g mode. So, to force your particular sim card to switch to 3g only mode, first deactivate/disable other sim card on Yureka from setting> sim cards menu. Then dial *#*#4636#*#* > phone information. Tap on Turn off radio button and wait until the button reads turn on radio. Select WCDMA only from dropdown menu above the button. Wait a few seconds. Now tap on Turn on Radio button. Your desired sim card will successfully connect to 3G network. Now go to settings and sim card option and activate the disabled sim card as well. You may need to manually search for network signal if no network is shown. Also you may need to restart the device. If in 3g mode, your phone doesn’t connect to internet, Go to apn setting to ensure correct apn is selected. Sometimes APN menu might not show any installed network settings, in such case, just restart the handset. All these network related issues will be hopefully solved in the next Yureka ota software/firmware update.

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.

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 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.
