Please give me one solution for that

Might be the rom. Try going back to stock.

issue remains
stock restored issue remains. do u have any suggestions?

APN
You may have lost/wiped your APN when you did the root. Check under your network settings for mobile network and then look for apn or access point names. You should have one or more APN options, if you don't, then you may need to manually enter yours.
APNs vary based on your carrier, so you'll need to either contact them or look them up on the internet. I'd be happy to help search if you tell me your provider.

My network provider is TATA DOCOMO. Actually what happens is if i try to connect , suddenly range disconnect after 2 or 3 seconds range will come.
Again i will do restart or airplane mode , first time range will be shown suddenly range disconnect. strange problem. i dont know whats the problem. i dont know how to explain. i checked the APN it is fine. Is there any problem in my RADIO?

With Reliance CDMA the problem was an unregistered MEID. Are you on CDMA or GSM. Tata are known to be the toughest on security, so must be some setting which got hit for six.

[Q] help!3G connectivity has gone from my phone

my phone can not connect to 3G networks in most of our city, while it used to work just fine in these same places. at first i thought there must be something wrong with the carrier's base stations. but today i tested my SIM card on another LU6200(Korean version of Nitro HD) and it works perfectly both on 3G and 2g networks on that phone. but when i put it back into my phone, it can only get 2G signal. if i set the Preferred Network Type to WCDMA ONLY, it got no signal with just a cross on the signal bar. i have to put it back into GSM ONLY mode to receive signal.if i go out, i can get partial 3G connectivity here and there, but not consistently. sometimes even if i have full 3G bar signals on the status bar, i can not make calls or connect to the internet.i've got this problem probably after i tried to forcibly go into the Phone Info menu.i got repetitive " the process com.android.phone has stopped unexpectedly" promps , and i just ignored it and tried again. now ,2 options are missing from the menu, LTE/WCDMA/GSM and LTE Global.in place of them, it's UNKNOWN. i already tried flashing KDZ package of no avail. Does this mean a hardware malfucntion or software glitch?Please help!Thank you in advance

Ask att store for a different sim card i had lte issues and new sim card helped try that
LG NITRO-N XDA APP

Well you do HAVE GSM only selected. THATS 2G(EDGE)
for 3G you would need to select WCDMA

^^^So true
LG NITRO-N XDA APP

No service - HELP!

Hi Everyone.
Stock O2 ICS- rooted - bootloader unlocked
I've recently bought used HTC One V locked to O2. Problem is gsm service never worked for me.
WiFi, Bluetooth, GPS are fine but emergency call only.
I've tried different sim, 2 custom roms, hard reset and no lucky.
Under mobile network setting I cannot swap between WCDMA only - Auto - GSM only, it is sticked to WCDMA/GSM Auto only
When push *#*#4363#*#* Cannot change network mode too, WCDMA preferred fixed only, if going to radio band selection cannot choose any (Automatic, EURO Band etc) just got message "Set [automatic or any] Unsuccessful.
What is weird, When I turn mobile data on with correct APN for my provider (currently giffgaff) I have gprs running and can send and receive data, but with my other phones I had before my service has been alwaysfast as 3G and HSDPA, not "G" like now.
Please see below my screenshots, I've checked my mobile network with many apps and there is what I've found

Ok this may seem a very stupid question but it happened more than once. Are you using the little piece that covers the sim card? That has contacts in it, without it there is no signal

If you still have warranty, run a ruu so it goes back to stock, and take it to the HTC centre. If you are lucky they will recognize it as hardware problem and give you a new one. Remember to tell them it never worked, and if they ask about root or stuff, you don't know about it

No I don't have a warranty (it's second hand and a have no seller contact anymore), otherwise I would not asking here. Looking for somebody who solved this, if.

I inserted my sim in a friend's phone in the same area and 3G was working fine. I went to Htc Sales and Service Store but they simply said they can't help! I have never rooted rooted my phone and done nothing with my phone except downloading apps from Google play! Can anyone tell how to solve this problem???

That's it.

Did you get 3G while choosing WCDMA Only?
If Yes,means you have to do it manually everytime you reboot your device.
If No,means you don't have a 3G data plan.
If you reboot your device mean while it will again set to prefered WCDMA so everytime you need to do it manually. Just to remember if you're getting 3G even on prefered WCDMA then leave it as it is. I think it's an issue regarding weak carrier signal.

I have tried everything like this....but still no results! I guess this is a problem of build.prop! can anyone help in this regard?

Its not the build prop. Its how HTC designed the DHD.
The DHD isnt quadband, You can check the specs at gsm arena.
Some countries have thier 3g on a different band, so if you buy a DHD that doesnt scan for 3g on your countries band, you face the same problem.
I have being trying to fix this problem but got stuck along the way. Its very good to see that people also have the same problem. Maybe the devs would try something.

dear, did you get any sulution for 3g network on dhd?

Nope..
Before i can try anything i have to put the device in diag mode which i have being able to, but the problem now is the device isnt showing up properly in QPST(a program for communicating directly to the qualcomm chip).
It detects the open port on windows but its unable to find the phone in the port.
If the phone doesnt show up in the port, changes cannot be done.
So thats the update.
If you have any idea, you could share

WCDMA
goto mobile network under settings, then select network mode, change it to GSM/WCDMA auto if it doesnt work then change it to WCDMA only.
It'll do the trick.

I have the same problem! You could solve it?

1. This may be obvious but you do have the sim in sim one?
2. Go to settings / more / cellular networks ends make sure you don't have 2g only selected.

Just update to 2.19.40.22 fw update..it has 3G stability and 3G works fine after this update..if you have older version this problem will persist ..

Same problem in my ASUS ZenFone 2 laser 550kl model finally said that customer care service executors better to check in authorised asus customer service centres the problem may occured due software issue...

Still facing this issue on Airtel Network in India at many locations. The network switches between 3G, H and H+ and hardly pages open up. Also, there are call drops when network switches from 4G to 3G/2G and 3G to 2G.
