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.

[Q] Mobile interenet not working on HTC ONE X

Hi,
My question is not regarding interet pass through. My question is that on my phone I cannot get my mobile internet working on my phone.
When I try to tick(select) mobile intyerent option on the phone, it doesn't allow me to change that option. I have read the forum on htc website. I believe that the latest software update for this phone model is the cause behind mobile interent not working on the phone.
I want to know, If anything can be done to solve this issue and get back the mobile interent to work on the phone?
May be by degrading (uninstalling) the software update to the previous version. Any help in this regard would be appreciated.
Regards,
S

Go and check your Access point name; setting>mobile data>access point name.
if there is no APN , you have to fill up your APN name.

Hi ,
I have checked, and can see the following APN'S
Optus Internet and Optus MMS
Optus Internet is selected and under Optus Internet , the name is "Optus Internet" & and the APN is filled as " yesinternet"
I just got this phone unlocked(originally locked on Vodafone Australia network)
Any other issue that might be causing this problem?

Yes , I am using Optus network sim, but the phone was originally locked to Vodafone network. I unlocked the phone, so now I can use any sim card in it.
I get the GSM signals to make calls, I can use wifi but its just the internet, thats not working. !

Yes, data roaming is "ON" mode. I have another phone- HTC DESIRE HD (on which I can use my optus mobile interent) and the settings on HTC ONE X is similar to the one on HTC DESIRE HD.
Was there any issue with the HTC ONE X latest software update(which was available few months back) ???

Yes, I have tried changing the network mode, it was gsm/wcdma then I tried to put it on auto or gsm, then put it back on gsm/cdma.
Also, I have tried searching for manual network and then I get two options - Optus and Virgin(optus network reseller), no matter what I select, the mobile interent doesnt works

I am using HTC DESIRE HD A1919. (Baseband version 12.65.60.29U_26.14.04.28_M) and (Kernel version 2.6.35.10-g931a37e [email protected] #1 Wed Nov 9 14:04:03 CST 2011). Recently 3G is launched in my country Pakistan but when my phone is not connecting to 3G. settings/about phone/Network/Mobile Network type always shows EDGE! 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???

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.

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.

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.

Help 4g

Hello friend, i bought a new m9 and when i activate data mobile i have only 3g , i tryed factory reset, to setup my network,
I rooted my phone, installed custom room.. still no change.. anyone can know why ?

Well maybe you dont have great 4g signal in your area? Or change apn.

As stated already , the signal could be weak in your area. Type in the dialer key pad ##3282# and you can also look to make sure all the bands are enabled on your device. I don't see why they wouldn't be though. A handful of users have stated bad connectivity with the M9, but that's on the sprint network I have been reading about.

at ##3282# it say only OK.. nothing about enable bands and i tryed sim of my friend (vodafone 4g) he have m8 and 4g working... on my m9 doesnt..

I have same problem with my M9+. In Manchester Area UK
I had perfect 4G with my old M8 but with new phone only 3G!!
Let me know if you get any answers. HTC and Vodafone couldnt help me either.

Check access point names, make sure only one is listed and selected.
Go to networks and search for network, click automatic.
Open the connectivity selection and make sure that the scalable option is chosen (2g/3g/4g)
Are you using one Base with the wrong firmware? Make sure they match up.
Find a friend on the same network or shared network and see if they have 4g in your location.
Test the sim in another phone.
Call network to check for issues in your area and or if there is an error against your account, may need a new sim if that one is old.
Test in major parts of the city center next time you're shopping..
Perform a speed test to see what speed you're actually getting, hspa is up to 20mb, 4g AFAIK is around 60mb, I've had 48 before. Anything over 20 could be considered 4g, you will very very rarely see a 3G tariff go over 19mb, which is the most I've ever seen.
Good luck.

I have the same issue with the M9. Couldn't find an answer for this problem. Even tried opening lte bands as listed here but no luck.
The thing is that I used to get LTE where I am now, went on long holiday and can't get it to work again so no idea what's up.

I tried my sim with my wife's iphone and i got 4g without any problem. It's not a sim issue. Whatever the problem is, it's with the device (hardware, software, settings). I remember it also took me a few weeks after getting the M9 to get a 4g signal, but then one day it just appeared so there's that to add to the mystery.

Reset your network settings mate, set to manual then back to automatic.
Make sure you actually catch the network on manual first before manual. You will find it, it's just a case of going through the motions.
Also click menu, reset to defaults in access point names.

1. How do you "reset network settings"?
2. set to manual - you mean in 'Network operators' menu select 'Search networks', select my network, then go back and selecting 'Select automatically'?
3. What do you mean "just a case of going through the motions"?
4. Should I reset APN at the last step or at the beginning?
I'm trying to understand your steps as clearly as i possible can because this no 4g issue took a lot of time and effort from me and it still doesn't work. Any help is very much appreciated.

I am trying to help you.
There are no steps it's just a case of trying everything to do with the network. If what you say is true and you've literally just had this issue occur out of the blue then it has to be a difference on the handset, especially seeing as you have tested the sim in another phone and it works.
Reset to default is with apn, doesn't matter when you do this just reset them, make sure it's checked and cycle mobile data on and off.
Clarify that your device is set to 2g/3g/4g within network mode (I believe it's called)
And I was referring to setting network selection to manual within mobile network settings, then choosing your network, then researching and selecting automatic.
The path is: settings / mobile data / network operators / search networks, wait for yours and select it, cycle mobile data (turn off then back on) if that doesn't work, switch back to automatic.
Reboot your phone after making changes, perform the full shut down method instead of the restart or power off methods, it's power and volume up AFAIK, hold for 10+ seconds, might be 15.
Going through the motions refers to checking anything and everything which influences the network, one of these setting will get it working..
Might be seen as overkill but a factory reset (if it's not been tried already) good luck.

I know you are trying to help me, and I very much appreciate it. Truly am.
I tried doing all the steps you listed, but no luck. Even tried at some point to force lte only in 4636 screen but that resulted in no signal at all. Trying to manually select a network in that setting only gives me the other 2 networks that work in the area but not vodafone which is what I use.
As a complete overkill I RUU earlier to the new 2.11.617 firmware without signing into my google account or restoring anything, and still no lte. What I did saw however, in the select network screen, was that next to my network, it said 2g/3g and next to the other 2 networks here it said 2g/3g/4g. Obliviously I can't select them as it's a vodafone simcard.
I added here SS from LTE discovery app while i was on 'lte only' mode. You can see signal is there but it cannot connect.
Any wild ideas or suggestions? I'm opened to try almost anything

Just out of interest, have you tried a different sim card? I know you said that your sim worked in another phone but I'd still be tempted to contact voda to get a new sim and to see if everything is set up on a network level, you may have to tell via that the issue is persistent in different phones or they may make you pay for it.
Also, might be something to do with the association between your phone and your sim. I once had a sim that blocked my missus, she could call me but I couldn't call her, no active diverts of any kind, I could call anyone and they could call me, got a new sim and it was sorted. Very strange, but anomalies like this do occur.
Have you got any mods or are you at stock at the moment? I know you said ruu. Oh and lol click thanks BTW.

Well the thing is that my wife's sim card in my phone only gets 3g. On her iPhone it's 4g. My sim card in my wife's iPhone gets 4g. On my phone only 3g so it seems like a very specific problem with my device.
Shortly after ruu I installed viper 3.5 without any mods..
Can it be that my device is somehow blocked by the network towers or something of that nature?
Maybe a hidden setting somewhere that blocking the phone's 4g capabilities? This is getting ridiculous..

No worries fella
If you've already tried another sim and it's still not happening, the firmware matches the rom, your sim works in other phones with 4g. Then I'm really not sure mate..
Give Lee droid a whirl that's what I'm using at the moment.. A simple but great rom..
I'm pretty much out of ideas now, if all of the above has been checked then it's something that I'm not aware of.. Sorry mate..
for the record it is a weird one, something should have got it working by now..

I can't return the device as it was bought in the states and I live in Europe at the moment.
I think I will try to change my sim card for a new one just in case, and will change back to stock 2.11.617 for a couple of days to see if that can make any difference.
Will post an update if i will have one.

Yes it would. He probably bought a cdma and has to have the correct bandwidths unlocked.

mate 20x Cannot connect to LTE network

I just bought mate 20x Global version EVR-L29
my problem is I am unable to connect to my 4g network
I tried to install apps like settings database editor to force 4G/LTE only for Huawei
but every time I pick LTE only or GSM/WCDMA/LTE or any type of settings my connection to my mobile network stop working
I lose mobile network connection and I am unable to do basic phone calls
The only way for me to make phone calls is when I pick up GSM ONLY
Any suggestions on what is wrong with my phone or what I should do?
I live now in Egypt using Vodafone network . The phone was bought from the USA.
thank you in advance for your help

Have you gone into your network settings and manually changed your apn settings to work with Vodafone? Google search Vodafone Egypt 4G apn settings or call Vodafone to get them. See if what you already have on your phone is the same.

I did the following so far and with no sucess
1-factory reset
2-tried 3 different sim cards with 3 different networks each one with the right APN settings sent to me from network operator.So i have no problem with sim cards for sure.
3-installed an app called settong database editor and changed hardware network preference to "11" an advice given on youtube to enable me to force phone to operate on LTE only
NONE OF THE ABOVE RESOLVED MY PROBLEM
I Still lose connection with network and unable to do phone calls once i pick any settings but "GSM only " for data connection.
I do not know what to do.

What version Android do you have? If it's 10 then you need to install the APN manually.

I did the following so far and with no sucess
1-factory reset
2-tried 3 different sim cards with 3 different networks each one with the right APN settings sent to me from network operator.So i have no problem with sim cards for sure.
3-installed an app called settong database editor and changed hardware network preference to "11" an advice given on youtube to enable me to force phone to operate on LTE only
NONE OF THE ABOVE RESOLVED MY PROBLEM
I Still lose connection with network and unable to do phone calls once i pick any settings but "GSM only " for data connection.
I do not know what to do.
