Samsung Galaxy S7 UNLOCKED (I bought it unlocked from an AT&T supplier) g930u
just randomly went to use my phone only to find I cannot. Only wifi. Airplane mode won't ever turn off (completely?).
Yes, I have tried to RESET EVERYTHING.
I searched for help all day. To no avail. Only thing I can think of now is to throw the phone in the trash or flash a new rom? Yes, I even tried this https://forum.xda-developers.com/showpost.php?p=41777704&postcount=50
Apparently I don't actually have wifi calling, but when I disconnect from wifi-it shows wifi calling but won't let me change it? WTF is that? (screen shot below)
All symptoms still point to be carrier locked to me, either that or your SIM card is broken. That little cross symbol next your alarm is when no SIM is detected, or it's not a supported SIM.
SIM works in another phone? If you boot into download mode what model does it say it is, they didn't accidentally sell you a G930A?

I was wondering if it could be that. I have another Sim Card for another carrier I can try, I was waiting to make sure it was not the phone before I tried it. (It effectively switches my phone service once i activate it -which is why i was waiting)
Download mode confirms it is a G930U

Did you have to unlock the phone to do that?
I called AT&T and they said that they don't have the unlock code since they don't even sell the device, but that it works on sims outside the US. She seemed to imply that it won't work on tmobile but that if I go outside the US, and just put a sim in, it will work without me having to unlock the phone in anyway.
Can anyone verify this?
Thanks

Most customer service representatives are pure idiots .... Nexus S is a Google phone , so it's factory unlocked to any SIM card you use with it(you may or may not get 3G on other networks depending on the other network 3G frequencies , and if the forgein network has 3G on 900/1900MHz it will have 3G on this Nexus S)..
Hope this helps..
Well I went to tmobile and the guy put in a sim into the phone and the phone got no reception nor did it seem to recognize the sim at all.
So it seems that it isn't unlocked.
I tried putting in this code: *#7465625#
Its supposed to tell you if the phone is unlocked or not, but nothing happens, it just says: Connection problem or invalid MMI code.
I don't need it to work on tmobile, but I do need it to work on foreign simcards. And I saw on other forums that for some people it worked on tmobile and others it didn't so there doesn't seem to be any clear answers.

you have another issue here , check your phone
Thanks for the response.
What do you mean by other issue and how should I be checking my phone?
In any case, I put in a simcard that my brother gave me which I believe is from Mozambique on a carrier Vodacom. It asked for the code of the sim when I put the phone is as always, and so I got in putting in 0000.
It then showed no connection to anything whatsoever, also as always.
Keep in mind I did have wifi on.
Then all of a sudden it asked me to update my phone and install something. So I just said yes and it updated and rebooted.
All of a sudden I have bars here and there and it recognizes that tmobile and AT&T are in the area. I also saw I think at the top of the notification bar when I pull down the notifications tab, it said Vodacom. Of course I get no reception whatsoever but that is expected, this sim was a gophone sim in Mozambique.
Does this mean that its unlocked if it is recognizing another sim, even though no confirmation of reception? I plan to try again with tmobile now and perhaps make sure I have wifi connection while doing so and leave it in for longer.
Thanks and please let me know if you have any thoughts.
what ROM you're on now?stock or costum one ? you also might consider a FULL phone wipe.because this might be caused by a difference between at&t apn or other Sim data and the other .check for that
I'm on stock 2.3 that the phone came with. Haven't messed with it at all.
So I assume you saying that if I want to switch to another sim, I should do full phone wipe then? so that the at&t apn doesn't confuse it?
IF it doesn't work with tmobile again, I will try taht, and I will also try to learn what an apn is.
Thanks for the help.
Might work or might not !!! backup all your data and apps first then use the shotgun method lol
But what I am sure of is that Nexus S phones are always unlocked and SIM free..
I have a bootloader locked, unrooted, stock Moto g 4.4.2 on Verizon Prepay. I can not get the phone to connect to 3G. I thought it was initially because I ran out of data. I put 3gb onto the account two hours ago and still am unable to connect to data. I have 3G service but the icon is highlighted orange.
I've tried Safe Mode, restarts, entering and exiting airplane mode to no avail.

This looks to be a common problem for the SIM variants. Still can't find a resolution, though..

The XT1028 is not a sim variant. Dial *228 on your phone and press 1 after hearing the operator. Afterwards dial *228 again and this time press 2.

What I meant was that this seems to be a problem prevalent with the SIM variants. I haven't seen this issue with the CDMA devices. However, I'm still having issues after re-activating and updating the PRL.
I sent Middleman a request for my bootloader unlock code so I'm hoping once I get CM up and going it will resolve my data issue.

Bring down the notification bar, tap Settings and the phone/data connection icon will have a muted orange color to indicate you're logged into Google Services. My phone (XT1028) has this too and im pretty sure my datas working. I wouldnt know since i didnt pay it this month because im testing out flashing stuff. BTW my phone has an unlocked BL.
I have the 920F model and activated it with a UK sim a few months ago.. Have been using a US sim for the past 2 weeks, but today I went into an area with no service for a bit. Went back into an area with service and suddenly it says 'Not registered on network' when I go to make a call and 'No SIM card'.
I have gone into flight mode, cleaned and checked SIM (not a problem with the card), and then when I went to check the APN settings I noticed there was no way to get into my 'Mobile Network' settings! Its just gone!
Is it possible that it has reverted back to the European region lock and is awaiting a European SIM to be inserted before I can re-insert my US?
If it is a region lock, is there anyway to unlock it without using a European SIM as I no longer have mine and dont have quick access to one either.
Any help is appreciated. Hoping there is an easier fix.
I think airplane mode disables that menu. Did you try to take it out of airplane mode again before looking for the menu?

Yeah, its not in flight mode anymore. I think it might be a region-lock issue but no way of knowing until I can get my hands on a UK sim!

Im currently having the same problem with my 920f. I dont think it is region lovk because i am using mine in the same region that it was produced for. If you have fixed the issue pls tell me how you did it. I also noticed that whenever you connect it to the pc, it is not being recognised.

Mine does connect to my PC. Haven't found a fix though - going round and round with Samsung and they say I have to bring it into a UK Samsung centre but I'm now in the US!
Going crazy!

If you go into your settings, under 'connections' does Mobile Networks appear? Try checking your APN Settings if so.
Has anyone found soution to this issue, and how did you fix it?
I am facing the same issue with my Galaxy S7 Edge (dual Sim) as i was traveling to another country (Europe). My phone is unlocked. I had to reboot in order to get back the "Mobile Networks" option.

Sadly reboot did not help me, same as different modem, radio, firmware, SIM card...
Still have no solution to this, if anyone can solve it, ill buy him a beer.
Same issue
Hi,
I currently have the same issue and I don't know what to do! Did you find any solution? I am really confused.

Depends on whether your phone has an imei, and whether you have to unlock it.

SN and IMEI is good in about the phone, when dialing *#06#, and in service mode (*#0011#) says IMEI: OK.
As for sw, I don`t see anything that is not good, anymore.
For half a year I am trying to find a solution to this issue, tried almost everything, even writing clean cert.
Last thing I am going to try is sim reader replacement, at the begining of next month, and see if that will help.
any progress on the issue? im having the exact problem,was using it one day and it just started saying 'no sim card' inserted even tho when i put in a sim it says 'sim card added' but right after goes back to saying 'no sim card inserted' , plus the mobile networks option had disappeared from settings. also, mine does not connect to my computer and it charges slow. my technician diagnosed it as either the mother board issue or the usb port and sim card reader issues respectively. will try a factory rest and see if that's any help.
*update* factory reset did not help.
I just upgraded to 6.0.1, canadian G920W8, I put it in airplane mode, I removed airplane mode and the cell network never got back up.
Thoughts?
I was able to get my connectivity back after a factory reset from the recovery partition. I am now afraid to push on "airplane mode" as I fear I will be locked out of service again...
factory reset did not work for me, tried both from recovery and settings, any other solution?
Hello!
I'm having the same problem. Is anyone who tried the software downgrade to lollipop??
I tried both Lolipop and Marshmallow, still the same..
anyone figured this out ? I have exact problem on my sm-g930f.
I brought G930FD galaxy s7 in Singapore during my deployment. It worked fine with other countries sim card. Now i'm back in US tried to use my phone with Verizon sim card
and it didn't work. I got signal but there is no network connection, only Emergency call pop up for a minute then gone.
I tried to adjust the APN but didn't work. Also my phone kept saying "Refreshing Sim Card" couple times. I did some reseach if it's actually region lock but I couldn't find a straight
answer for it. I wonder if this phone is really region lock. If not then what could be a problem for it?

From what I know, in order to unlock the region lock, you have to make at least 5 minutes of phone calls in the place you got it. At least this is how it is with the European version I have.
Now about the network issues, if it wasn't a carrier version then it should be unlocked, meaning you can put any Sim card.
My bet, since it's from another country, is that you have to call Verizon and ask them to let it in their network.
I don't believe the G930FD supports CDMA...it is a GSM phone. This is means no compatibility with Verizon or Sprint. You need the US version of the S7 (with the Snapdragon chip) to get CDMA support.

Hello!! I'm new here! I hope I'm posting this in the right place. I have a TCL 30 XE 5G (T767W) from Metro by T-Mobile and I had it sim unlocked by an eBay seller who had me hook it up to my PC via USB. The settings menu says it's still locked but it does accept sims from other carriers so I think it's unlocked. The problem is that it won't find any service at all with any sim other than the original Metro sim unless I set it to 2G only mode. Even selecting my service provider from the available network list doesn't work. The only way I can get the phone to find service is to force it to connect to 2G then change the network mode to LTE and then finally set it to 5G and that doesn't always work either and even when it does it's only a matter of time before it randomly disconnects and is left forever searching for service but never reconnecting until I set it back to 2G only mode again. All this is happening in a city with great T-Mobile coverage and all of the sims I've tried run on the T-Mobile network. The only sim that works without any fuss is the Metro sim even after the phone was unlocked. I'm using the phone on a T-Mobile MVNO now but it always disconnects sooner or later. I don't understand how a new phone can't automatically find an LTE or 5G network without first connecting to 2G and it doesn't find that either unless it's set to 2G only mode. Aside from the obvious inconvenience this causes, T-Mobile plans to shut down their 2G network soon at which point this phone won't be able to find service. Has anyone else run into this problem? I have two of these phones both are doing the same thing. Did something go wrong with the unlock? Is it a software issue? I tried asking my carrier for help but they can't figure it out either. I appreciate any help or info anyone here can offer. Sorry for the long post.
i suggest taking into a service and getting it there unlocked. perhaps your method prove faulty.
