[Q] GPRS not working in HTC G2

I have a problem with my HTC G2 mobile. I can't get internet via gprs. I checked with the service provider and all the settings are correct.
My mobile software specifications are
Android Version: 2.3.4
Baseband version: 12.62.60.27U_26.13.04.19_M
Kernel Version: 2.6.35.10-g96de068 ([email protected]#1)
Build number: 2.16.531.5CL159515 release-keys
I connected to Wi-Fi and its working absolutely fine. Anyone has the same problem? Please help me!

Right off the bat I don't have any great ideas on how to fix this (except for missing apn settings), but I believe some additional info would help.
Do you have root and s-off?
If you are rooted, which rom are you currently running?
Is the issue the same with other roms?
Are you getting no mobile data connection at all or is it only gprs that you're not getting? (meaning edge, 3g, hdspa work?)

[Q] No 3G with stock or custom firmware

If you have read my previous posts you will know that I recently tried to update to Doom Kernel and Ice Bean. I couldn't get wifi or 3G working so I tried flashing Arc Knight and Jelly Sandwich. I got Wifi working but still no 3G.
Using flashtool I changed to stock .431 firmware but I still don't get 3G. I live in South Korea and have a South Korean model Arc (LT15i) on SK Telecom. I think they use a slightly different protocol here for cellular communication (wikipedia says UMTS/HSPA), could that be the problem? I have searched the forums and the internet and not been able to find any original Korean Firmwares.
Please help, I really don't want to be using the stock firmware because of all the crappy bloatware! (I should mention that 3G/HSPA was working on the stock gingerbread firmware I was using before.)
Info: the phone's SI number is 1247-0400
Thanks
Edit: Just had a look around on some Korean sites and it seems that the global rom is working OK for them. Could it be the internet settings are not downloading from the operator correctly?

Are your antenna at WCDMA/GSM setting??

Yes it is. I think it was something doom kernel did

OK... after much digging around and testing of my Korean skillz I fixed it! As I previously suspected the internet/data settings were wrong and the 'download internet settings' button wasn't working.
In case of anybody else with a Korean SK Telecom phone here is what I did:
Settings -> Wireless and Networks -> Mobile Networks -> Access Point Names
Use the menu button to bring up the option of making a new connection and use these settings:
Name: SKT
APN: web.sktelecom.com
mmsc: https://omms.nate.com:9082/oma_mms
MMS Proxy: smart.nate.com:9082
MMS Port: 9093
Authentication: none
Menu button and save. Return to the Access Point menu and select SKT.
That's it!

Kernel: 3.0.8-599060-user

Somebody in Austria unlocked the phone. I works now with other sims but Tethering did not work in Austria.
I installed an APP: One klick Tehthering and everything was ok.
Now I came back to US and my AT&T sim is giving me problems.
There is no connection to the internet available (no 4G,3G or Edge)
What can I do? I do not want to use the Iphone any longer!!

Verify your IMEI

1. Do you have data plan?
2. Verify IMEI.
3. Verify APN.

[Q] ROM Radio Problems

Hi, I recently got a I9195 and started to have some setup problems at the time of saving the apn settings. It seems that the radio doesn't work, since it randomly disconnects the 3G connection and I have to restart the phone to make it work again. Recently I discovered that I can't make any phone calls when it disconnects mobile data.
I think that switching on-off wi-fi and mobile data is the action that freezes the application.
The original Android version 4.2.2 was updated to 4.4.2 to check if this was solving the problem.
Bandbase: I9195XXUCNE6
Kernel: 3.4.0-1646188
Firmware Version Info
PDA: I9195XXUCNE6 CSC: I9195PHECNE1 MODEM: I9195XXUCNE6 CHANGELIST: 1646188 BUILD DATE: 23.05.2014
Is the anything I can I check? Anyone else experienced the same problem?
Cheers.

[Q] Samsung Galaxy Note II working only on one GSM network

Hello, This is my first ever post on this website. Please bear with me if it's too long or confusing.
I have a Galaxy Note II I317. It's basically an AT&T phone but when I insert SIM from another carrier (e.g. H2O) it doesn't ask me for an unlock code. Moreover, I have an unlock code from AT&T as well.
The phone shows full signal strength for the mobile carrier. However, I'm unable to send sms or make a phone call. Whenever I try to place a call, it says "emergency calls only". I tried this in USA and now I'm in Pakistan.
Here, I encountered the same problem. We have five major networks here in Pakistan. Ufone, Zong, Telenor, Mobilink and Warid. I tried with Ufone, Warid and Telenor. The phone works OK with Telenor but experienced the above problem with Warid and Ufone. I have rooted the phone, downgraded to 4.1.1. and then back to 4.4.2. However, nothing seems to work. Mobile repair shops are also of no help. If anyone has any idea, I will really appreciate this.

Hi,
You can try this thread, and ask about it here if you wish,
http://forum.xda-developers.com/showthread.php?t=2037017
Good luck!

I have tried this method but I don't get the option "now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ".
I looked around on internet for this problem and found that this methods works with 4.1.1 and below. Moreover, this is for mobiles which ask for an unlock code. My Galaxy Note II doesn't ask for an unlock code.

I will have your thread moved then to your device section, so the experts who own your device can help.
