[Q] Unlocked G2 wont connect to network?

I just recently bought an unlocked LG G2 and set up the phone on a Koodo plan. The phone has worked great up until a few days ago when I lost service and the phone wont connect to the network anymore, even after a factory reset. I brought the phone to Koodo and spoke with a guy that told me sometimes unlocked android phones have difficulty connecting to a network and that he didnt know how to help me. Ive tried manually entering network information and ive tried different koodo sim cards but nothing works. What should i do next?

Try another simcard provider
Try gsm only
Try to search fir network in network settings

Hi sricard,
I seem to be having the same issue as what you're experiencing. I have unlocked G2 that I'm using on Koodo network. Just last night my phone switched to emergency calls only. It was working perfectly fine for a whole month. And before that I was using the phone on Fido network with no issues.
Some additional info. I tried my friend's Roger's sim card on my phone and it showed emergency calls only. When my friend tried my sim, he was able to connect to Koodo network.
On my phone when I search for networks, it does find Koodo, Rogers, Bell networks. It just doesn't seem to be connecting for some reason.
My phone is stock, not rooted. I wasn't even doing anything out of the ordinary with my phone so I have not idea why this happened all of a sudden.
I tried the hard reset also and that didn't work for me either.
Not sure what else to do. May look into custom rom but not sure if that's going to work..

What I found out is that my phone had been blacklisted... which means that it had been reported lost or stolen by somebody else and the IMEI number had been reported. The phone became useless... and as one of the guys that i brought it to said, i essentially had a very expensive paperweight. hope your situation turns out better than mine!

I also have the same symptoms as this, checked the IMEI with Koodo on the phone. They don't see it on any of their lists.
I'm trying everything but can't fix it. Still trying.

Hi. I am in the same situation. Days ago i bought and unknow person Lg g2 d802. I think i have a solution for work back again our devices. Please contact to my email. [email protected] and i explain to you my idea.

Similar Problem
I have an lg vs980 and I was using it with H2O wireless and later I changed to Simple Mobile. I'm living in Puerto Rico. The phone was working all right and, suddenly, one day it was always displaying 'emergency calls only'.
I did factory reset, then I reflashed stock lollipop and it was like nothing happened, keeps displaying 'emergency calls only'.
Then I found this post http://forum.xda-developers.com/show....php?t=2394689 and applied the patch but didn't seem to resolve the problem.
As a last resort I tried flashing cm 12.1 and before first boot applied the patch from the cited thread but no result, keeps displaying 'emergency calls only'.
Has anyone found a solution to this problem?

Vodafone UK, unbranded S7E, any way to get WiFi calling at all?

[SOLVED]
Please see this comment for how I weirdly got WiFi Calling.
Hi guys, signal in my house is horrific - I've been trying to get WiFi calling for ages, and loved it when I was with EE.
I'm now on Voda and don't have it.
From what I've seen, it doesn't appear to be possible with an unbranded phone (why Voda!?) through any normal/configuration means.
I have the option to turn it on under settings -> applications -> phone -> wifi calling, and I've sent 'CALLING' to 97888, but only get the confirmation of the text, and nothing to confirm it's been set up. However, I don't get the little icon to signify that I'm using wifi calling.
Is there any way I can get wifi calling?
Does it require flashing?
If I'm going to have to root/flash anyway to get this feature, is there a way to do it one of the nice custom ROMs I see on this forum, but retain the vodafone branding?
Thanks all.

Easiest way is to flash a Vodafone firmware. Had to do the same to get EE WI-FI calling working. There is an option in unbranded firmware but activating it does nothing

Just flash latest Vodafone firmware that way you will not trip knox and you should get wifi calling

I suggest you check with your provider, if the unbranded phone was not bought from them.
Wifi calling may not be allowed because the imei is not registered to a vodafone branded phone.
They may have blocked the wifi calling feature.

Hey,
I've got the Google Pixel phone which I bought from Carphone Warehouse. Vodafone have told me that WiFi calling should work with it without any special firmware. I've tried using my SIM card in a friend's Samsung Galaxy S7 Edge which he bought from Carphone Warehouse and it worked! I too didn't get a text message from Vodafone when I texted 'CALLING', but WiFi calling is now active on the SIM card, albeit not the phone. Have been in discussion with Google who have escalated my problem to their technical people. Hope it can be resolved very quickly, otherwise returning the Pixel, which I don't want to do.

Thanks very much for the replies guys - I have something to report back to you all too. Unsure HOW this happened, but it happened... I somehow got WiFi Calling.
I'm scared to try do anything else like switch off my phone, because I don't want to lose my new WiFi Calling.
Here's what happened:
I have an EE iPhone 5s, locked to carrier. I'd recently requested an unlock from EE. It had been switched off, and was recently hard factory reset. Unsure of iOS version.
I put my Vodafone SIM in the iPhone today to see if it had been unlocked... it hadn't. SIM was in there for roughly 1 minute.
I put the SIM back into my S7E... started getting the usual texts from Vodafone about changing SIM, blah blah.
Somehow, I now have WiFi Calling on my unbranded S7E on Vodafone!
At no point did I switch off my S7E during SIM changing.
*NOTE* I'm not sure if something has changed recently, but I definitely did NOT see the WiFi Calling symbol before I did this:
I have no idea why/how and I can only speculate.
But... there we are!
Not sure if anyone else can try/vouch for this, as I realise it's a VERY particular set of circumstances, but I hope this helps someone!
Please do respond to me if you try this out and get it working... it'd be interesting to see if it works for others, and maybe figure out why it works.
Cheers!

New! Three UK help required? Issue with WiFi calling and want some advice...

Hi Sorry if I am posting in the wrong area, but first time here
Basically, I have a Samsung Galaxy S8 which is being used on the Three UK Network but because I did not buy the phone directly from Three, they will not enable WiFi calling and I have to use their app instead, which is rubbish!
I want my phone to think it was bought from Three UK so this feature works. I guess by rooting it and adding their firmware etc this will work, but unsure?
Can anyone advise me on this?
Thanks

Problem with SM-G935FD on T-Mobile

Good day, hope you are all enjoying the weekend.
I searched the forums for my problem but could not find any solution. Appreciate all the help you can assist me.
Here it goes:
I bought my phone unlocked from Saudi Arabia, a Samsung Galaxy S7 Edge Duos Model # SM-G935FD and it is working perfectly when I was there. The phone is updated and non rooted.
I moved back to the US 3 weeks ago and now using T-Mobile SIM only. SIM2 slot is empty.
The problem I am having sometimes when people call me, the call will either go directly to VoiceMail or rings 2-3 times then goes to VoiceMail.
Of course my phone shows no missed call notification nor does it ring, and after 1 hour I receive a notification that I have a new VoiceMail. Sometimes I receive it instantly and sometimes after 1 hour!
Mind you it seems to happen randomly and at first thought the reception in my area was bad, but it happens when I am away from home as well.
If I remember correctly it has happened to me a couple of times when I was in Saudi Arabia.
I have been reading lately here that using LTE/3G/2G Auto might be causing the problem.
Since this morning I am on 3G/2G/Auto setting and it seems to be receiving all calls with no problem.
Is it a problem with the phone or the network and what can I do to remedy it?
Thanks in advance!

There were reports showing issues about not receiving calls and forwarded directly into voicemail on dual-sim models but only on s9 s9+
I hqve the same s7 edge duos (bought in Dubai) and don't have the problem, probably is a ROM issue. Try BTU ROM for 935F the one I'm using now.
935F roms works on our 935FD's (also detects our dual SIM)

Thanks for your reply.
I'll install the BTU rom and hope it solves the problem

Well last night I installed a BTU rom and all is working.
But today just now the same problem happened.

Oh, really? What about call forwarding status?
On Phone app go to settings>more settings>call forwarding>voice call

Hey there sorry for my late reply.
I am currently using another phone in the meantime and planning to switch to Google Fi and buy a Pixel 2 XL.
I really think the problem is with the phone. My father has a T-Mobile SIM and an international LG V20 device and it is working perfectly.
I think the S7 Edge cannot properly connect to T-Mobile cell tower.
Also I am browsing the site: https://www.frequencycheck.com for more answers.

Did You manage to get a solution?
I am in the same boat. Bought phone from Dubai. Worked well for 6 months, till December 2017 but now it has the same problem as you faced.

Well not really a solution but here what I did:
I switched to Mint SIM and bought a Pixel 2 XL, which is working perfectly.
I gave my S7 Edge to my mother and she is using H2O Wireless SIM. So far it is working fine.
Hope this helps.

Hi there, I currently have the same phone and I too was experiencing connectivity issues when I first received it. I basically flashed it with a T-Mobile compatible ROM and changed the CSC to "TMB". This solution will have your phone running on a ported stock version of Android 7.0 (Nougat):
T-Mobile compatible ROM:
https://forum.xda-developers.com/s7-edge/development/rom-nougat-7-dplt-wifi-calling-volte-t3540723
CSC Selection Utility
V2.5.0 Android 7.0 Nougat
https://forum.xda-developers.com/s7-edge/development/utility-flashable-csc-selection-30-t3392957
Select the CSC as "TMB"
I hope this helps!

I have the same issue, Samsung S7 edge from United Arab Emirates not receiving phone calls with T-mobile

Custom to stock for VS995 for UK use

I've been on AlphaOmega ROM and want to revert back to stock as I'm selling the phone but I'm a little stuck. I've downloaded what I thought was the correct ROM
VS99520c_01_1110_ARB00.kdz (region VRZ)
and then tried
VS9951AA_01_0122_ARB00.kdz (region VRS)
The reason I'm stuck is I'm getting a notification saying Verizon Wireless does not recognise my sim. I'm in the UK (imported from Hong Kong) and quiet happily have used the mobile network data & voice on various providers though probably not as well as a phone intended for the UK market. It's my own fault for not backing up the original ROM I know :crying:
The other thing is and I'm not sure if I'm imagining this but I'm pretty sure when it used to complain about the sim which it would after every reboot it would say Verizon and not Verizon Wireless and it would still manage to pick up the local bands. Now I'm getting nothing, nada!
So any pointers would be appreciated :fingers-crossed: Am I using the wrong ROM?
