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

what could be the problem

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?
I swapped sim card on my cell phone, i have n9005 (running 4.4.2 TouchWiz Rooted) and works on every network in my country,
the other sim card worked fine, i kept on swapping 2 sims because sometimes i had to use 3g on the other network.
Today it suddly stopped, now my both sim cards are not working.
I have restarted my phone, pulled out battery and also reinserted my sim card, no success.
Any solution?
EDIT: I fixed it, thanks

how?
You probably have damaged something in your sim card slot probably a pin.. as you said you usually keep on swapping sim cards.. have a repair center look at it..

Actually my network mode was WCDMA and had no 3g signals where i was..
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.
I've been a T-Mobile customer with my OnePlus 1, got the OnePlus 5 today and went by the local T-Mobile store and got a new SIM card. A couple hours later I got around to actually setting up my phone. I realized I wasn't getting app verification codes, so I called T-Mobile to make sure the SIM card activated properly. She had me confirm the SIM card was inserted properly, then she had me turn the phone off and she "sent it a signal." That got text and data working, but still no go on the phone. She transferred me to the next tier up tech support. On the phone with them, we turned off WiFi, WiFi calling preferred, VoLTE, and automatic selection for Network operators. The phone did it's search and we selected T-Mobile 4G for the Network operator. The phone says it registered on the network, but T-Mobile says it didn't. We tried the second SIM slot but no change. We did a couple reboots and still a no go. I was then told that since it's not a T-Mobile branded phone, they can't guarantee that it will work. They recommend I put the SIM in a T-Mobile phone to confirm that the SIM works - I'll do that when I get home and try it in my wife's phone.
When I turn on VoLTE, I get text and can make calls, otherwise if I make a call, it just calls T-Mobile.
Under Settings > About phone > Status > SIM status, Cellular network state shows disconnected.
I also see under Settings > SIM & network > SIM 1 > SIM name it shows the name as T-Mobile but Carrier says Unknown
Fresh out of the box, running 4.5.3. Has anyone else had any problems getting their OnePlus 5 to register on T-Mobile? I searched the T-Mobile support site but didn't find anything helpful.
I'll try the SIM card in the wife's T-Mobile S7 when I get home, but if anyone has any pointers, I'd appreciate the help.
OnePlus 5 on T-Mobile here and no issues at all.

Same here. I also have 0 issues
Are you using the latest 4.5.4 update for OP5? They had fixes for VoLTE not connecting. Even though I think that was Europe only thing, the download made its way to my phone automatically. If you're not on 4.5.4, go upgrade (it's a simple thing to do)
What are your APNs set to?
Goto...
Settings
Sim and network
Sim x (1 or 2, wherever the sim is installed)
Access point names
Without doing anything besides entering my sim card into the phone and starting it, I have 4 options
If you have anything outside of your current provider, add them. The easiest way to do this is to open up another TMobile phone you have, goto to the same location on that phone and copy settings manually to your OP5.
I did this for my wife's S7 coming from Verizon. Although she doesn't get WiFi calling without flashing firmware (which I'll be doing when she's ready) you shouldn't have that issue.
Bad SIM card
Turns out the SIM card was bad. Went to the T-Mobile store, let the guy double check everything, then he grabbed a new SIM card, popped it in and two minutes later everything was working. I asked him how often he sees bad SIM cards, he said one or two a year.
Hi All!
I own a Lenovo K6 Power as you can already tell,
in which the Data functions were working without any issues.
A few months back I started using 2 sims instead of 1. Since one carrier had faster internet and better connectivity than the 1st.
Still using the 1st SIM for calling and 2nd SIM for data. Occasionally I would switch to the 1st SIM for data when my data pack was over for the 2nd SIM etc...
So one fine day, I was switching back to SIM 2 (Sim I use for data) (Normally when you switch SIMs both deactivate and reactivate with new settings ie SIM 2 for Data).
So while this was happening like usual it took a few seconds to switch SIMs in the midst of this I suddenly got a call...
Which I was unable to answer till the buffering animation left my screen.
When that did get over... Both my SIMS were set to EDGE 2.5 g when they were always recognised as HSPA 3G and 4G LTE for SIM 1 and SIM 2 respectively.
Now I am unable to attain the speeds I used to, it is just barely usable now...
I then tried the usual troubleshooting (Airplane Mode on/off, Deactivating / Reactivating SIMs, Swapping SIMs physically from their slots and Finally Rebooting...)
Now when I recently tried doing the same my 2nd SIM which I usually use for Data appears as SIM Card Not Ready...
However, when I individually insert SIM 2 it is read by the phone
But still, whether I individually insert the SIMs or together the phone recognises both the SIM cards as 2.5g EDGE.
They used to be HSPA 3G and 4G LTE.
But now I can't use Data on my phone which is the major problem...
Please Help
Reset ur phone.
Is there any other option?
Apart from this...
I don't want to lose my data.....
What if that doesn't solve the problem...
