[Q] Unable to use 3G on unlocked HTC Desire

Hi,
I am unable to use 3G on htc desire. I have set the correct APN. The problem is that when I choose "WCDMA" as the network mode, it automatically switches back to "GSM only". The place where I live has no problem with 3G availability. I feel the problem lies more with my handset. Can someone please help ? Is there anything that I can do to get rid of this problem. My phone has lost its warranty since I unlocked it.
Have you tried any other operator sim card? It's a good troubleshooting to do when this kind of problems happen...
Had problems like that before and it was an incorrect APN setup.
Thanks for getting back. I tried with a different sim and a different operator. They were also not successful. APN setting is perfectly right for the current sim. The APN settings were given by the operator.

Are you using any kind of widget to switch APN on / off, 2G/3g ?... I noticed that for example, Widgetsoid can mess with 3g connection so much that sometimes you need to remove it and reboot the phone so you can get things working again.
Try using another SIM card too. It may give you a clue on what's going on: wrong settings / card with no data activated / etc ...
I am not using any widget to turn on/off the 3g. EDGE services work on my mobile while 3G is not working. If I use the sim card on to a different mobile, 3G works fine without any problem. Tried using another sim card with 3G data activated and that also did not work fine for me on HTC Desire.

Volte how-to ?

So I call up my carrier and ask them to activate Volte on my sim number. Carrier verified that it's activated within 30 mins and once I switch it on in my phones menu it'll work.
Restarted phone but no change in the settings? No Volte option..
Searched a lil and found some mixed answers between flashing AL-00 and the US version to get the menu to show up.
I even installed shortcut master to get to the hidden sub menu but all I was able to find was wifi calling, no Volte..
Anyone in my situation that was able to get it to work? A friend of mine went as far as updating to a new sim to get Volte working on his iPhone... Could the sim be an issue? Could a software update/rebrand fix it for me?
I'd like to try everything from my side before paying for a new sim with no guarantee that it'll work..
Any help is much appreciated

Hi!
The same thing happened to me, I couldn't send messages or call until I activated the automatic network mode, otherwise it wouldn't let me call.
I hope I have been helpful with this.

The same problem happened to me, i tried everything..
The only thing that fixed it is:
1. Insert a Sprint SIM card (in my case it came with the device when I baught it. I never had service from sprint and I lived overseas)
2. Select settings >> Network and Internet >> Network settings reset.
3. That is it!
Please note that this method only worked when I inserted Sprint Sim card, it did not work with my actual sim card..
After the settings were reset, I removed Sprint SIM, and inserted the other SIM, and it worked perfectly!

This worked once for me, then I had to remove my tray to insert an sd-card and didn't work anymore... network settings struggle to reset (will take 10-20s and then crash out) what could it be? I'm using a heicard and discussing the procedure in this thread: https://forum.xda-developers.com/t/unlocking-lg-g8-sprint-bad-esn.4092771/page-2
UPDATE: if you still get the "SIM not provisioned for voice" message, do a backup, then full restore of the phone, then repeat the above steps. You should now be able to make phone calls, but not connect to LTE. Download an app called "AddAPN" from the play store and manually save the Access Point Name for your carrier (yours will be different from mine, but I'll add it as reference, it's in italian, but you should get the gist, relevant steps are 10 through 14: https://www.helpforsmartphone.com/coopvoce/it/lg/g6/android-8-0/guides/22/Configurare-Internet-LG-G6)
with my sprint lg v50 and i can "Add APN" already.
i dont need an app
@en11gma Are you on android 9 or 10,and what is your security patch level?
Thanks.

How to fix the phone calling bug issue?

Hello,
I have a problem with the Poco X3 NFC.
Some times the phone seems to be disconnected from the mobile provider.
I can not make or receive any phone call.
I have to put the phone for a while to airplane mode or to reboot it to be able to make a voice call again.
I read that maybe changing the sim card fix that. I changed the sim but the problem still exists.
I have setup as prefered network the 3g instead of 4g but also this does not fix the issue.
Is anyone having the same issue? Is this a known bug that will be fixed with an software update from xiaomi or I have a problematic phone?
If there is a known fix, please let me know.
Thanks

[Help Thread] no service or emergancy call only after switching bands.

Hello everyone !
Before you read here is the specs and what I tried but didn't work to solve this issue :
Model : galaxy s5 (klte )
OS : Havoc OS 3.7 latest
Root : magisk21.1
Solutions I tried :
1 - restarted the phone .
2- clear factory reset and reinstalling the ROM.
3- checking my IMEI and its fine doesn't need repairs *#06#.
4- switched Sim cards and tested other Sim cards still no results .
5- return the official android OS still no use .
6- any other obvious solutions didn't work such as backup and restore my IMEI/EFS , airplane mod .
7- choosing network operator in the settings results a crash while searching so I can't choose manually and only be able to let it at automatic .
so lately I just bought a 4g Sim card and I know the galaxy s5 support 4g bands as I inserted the SIM it worked normally yet I wanted to switch the band to LTE so obviously I went to *#*#4636#*#* and switched bands so I can see which one would work yet suddenly while switching a couple of times the signal stopped showing and emergency calls only even though it reads the Sim card .
i tried to manually chose network operator but it crash's while it search's for it no matter what OS I install even in original so if anyone knows a command line to manually chose a network operator that would be appreciated.
Anyone know what to do ?

You may need to contact customer support for your carrier, they may have to fix it in their network.

The thing is about my carrier that they have a terrible customer service in here as if it was almost non-existing so I'm left all alone to deal with the problem plus there aren't any customer service for Samsung or any other external fix center for smart phone that's why I had to learn things on my own.

If you can't get back into that dialer menu and if flashing the firmware isn't fixing it and if booting into recovery and factory resetting the device aren't working, I'm not sure if there is anything you can do.
