My i747M stuck on LTE.. - AT&T Samsung Galaxy S II SGH-I777

I updated the phone and when I try to call a call on LTE is hangs up calls. Also receiving calls send people to my voice mail. The phone supposes to switch to 4G when making calls and it doesn't switch.

Please close this post. Stupid Tapatalk app made a mistake..

...... Crickets......

Lol.. Lots of them. I figured out the problem. I had the LTE band locked. So when I receive a call it won't switch bands.

Why did you post it here in these forums though?
That's dumb. Not even a similar device

Carrier Flashers

I flashed this device to verizon and it worked fine until i ran a program called wifi kill. Idk what the program did but it reverted all of my flash information back to sprint. So i had the flash redone again and now Im having issues.
I can make calls and send texts but i cannot receive the calls. The calling phone gets the ringing tone but the HTC does not ring at all. also I cannot receive texts. I text myself and the texts only come in when I make an outgoing call on the device or when i first torn on the device, the texts come in but after 10 seconds, no more texts enter the phone.
Can anyone help or have any clue to why this has happened?
And my data is working fine. 3G
Do you have the Verizon prl installed? Other than that it might be screwy bc you're not supposed to be on that network. Verizon doesnt recognize your number?
I'm sure you have heard it all before, but sprint can terminate your account for doing what you're doing.
i got it all sorted out. No i dont have an account with sprint. I specifically bought this phone to flash it. I bought it with a bad esn.

What did it end up being?

emergency incoming call? what is this

Today I received a call from a telephone scammer, but when incoming it came up as an "incoming emergency call". How can this happen? Am I able to make my outgoing phone call display as an emergency phone call? I have never seen this before, definitely weird. Indian or Arab lady on the other end when answered. I hung up.
Has anyone ever seen this. This is definitely different...

Not getting texts

My gf has been complaining about her not coming in or sending. I've read a story about sending people coming from iPhone might have the problem but she had a Note 5 previously. Anyone with the same issue or have any suggestions?
Check with carrier first. Then a network reset.
i've got a verizon phone with a t-mobile sim to complicate things, but yeah, i've missed texts and calls. i'd just suddenly get a voicemail without the missed call

Question AT&T phone calls

I have At&t and just got the Oppo Find N, chinese version. When i got to make a phone call, it pauses and sometimes doesnt seem to even connect before the call goes through. Data and texts seem to work fine with no hesitation. Anyone else having this problem or any advice? Thanks!
I had the same thin happen while in the office at home is working well.. not sure will test again tomorrow.. are you still having the issue ?
Sorry lads, i was on the same boat as you just a few days ago. My Find N also stopped making and receiving phone calls. Turns out AT&T shut down its 3G services hence you're unable to make phone calls. You'll need to switch to Tmobile if you want to continue using the phone. Tmobile is retiring 3G in July but I believe it handles phones differently than AT&T so we'll still be able to use it after July.
Not sure if that is the case I am on ATT and my Oppo N is on 4G able to make calls…
and might have spoken to soon.. unable to make calls any more.. The weird part is that SMS and 4G internet works..

It is pretty much the case. If youre able to make phone calls currently, it means ATT hasn't shut down the 3G towers in your area. They have plans to complete shutdown by Feb

Right..... You didn't speak too soon. The towers in your area were just shut down. You'll have to switch to Tmobile now.
Since folks here are talking about T-mobile, I have a question.
Does 5G work with it on T-mobile (I'm in the US)?
I saw that it supports n41 which is one of the band supported by T-mobile. But just wanna double-check.

I'm on T-Mobile, and have not had working 5G.
That doesn't mean it doesn't work somewhere... But not here in LA.

I guess 4G LTE speed wasn't too bad?
I've been on both and honestly my 5G UC indicator shows up but the speed difference is not perceivable.
Suggest trying to manually change the band preference using a utility such as '5G LTE' by Rudra Green on the play store. This allows lots of different LTE and 5g options to be selected. The only problem is that the setting is lost after the phone is restarted. I have been using this to enable 5g in the UK.

Question Strange behaviour

Hi all,
Today, my battery level was only 20%, the phone suggest activate economy mode.
I made this when i was at work i start a full charge.
During charge and after, all work Wifi, internet but no phone call possible.
I see logo for network reception and 4G.
After full reboot, call work again ... But not secure because you see 4G logo and then you think full work but not.
Nobody with the same thing ?
Since this behaviour, i'm not sure at 100% that my phone work for calls and i've a little doubt in my mind ...

Not seen this issue; normal calls and wifi calling both working well; but then I'm in the UK on BT/EE; I hear some of the US network bands don't work so well with the phone?
Once fail again this evening ... I was on Telegram with my wife and we are speaking with text but she said now i try to call you but it's your voice mail.
On my Find N, i've logo 4G and level max for reception ... Then il try to call my wife but don't work for call.
After reboot phone, same issue and don't work ... and few minutes later, it's work i receipt voice call and i can call.
What's happening ? I'm so sad with this ... It's as dream phone but i've doubt for receipt and make voice call. Help me please. :-(

Sorry to hear that. Only thing I can suggest is to try a different network provider (as the problem sounds network related?), turn on WiFi calling if at home, or actually call via Telegram (effectively over 4G using mobile internet), or WhatsApp.
i am in the US ATT same thing happened to me would be able tog et text and use internet in 4g but ransomly would not get or be able to place calls. Its a great phone but could not risk not receiving calls.
If you're using ATT, your phone is about to become a lemon. When you make or receive a call, it uses a 3G network. ATT is shutting down their 3G towers this month so your area has probably shut down by now. Switch to Tmobile, it uses voice calls differently so you won't be having an issue.
I'm from Belgium and my provider is Mobile Vikings.
Mobile Vikings use the network from Proximus (most big provider in Belgium).
It's random, i'm afraid with this ...
I love very very very much this phone but i need to solve this :-(
After to speak with my local provider, confirmation that my phone full work and compatible with Mobile Vikings.
Mobile Vikings is in transition for to full pass to Proximus and then they give me a procedure for reboot and make some specific settings.
I try few days and comeback here for give you news and débrief.
