I am d user of htc p3452. I have network problem with airtel simcard however it works fine with vodafone sim but airtel does not work. Any solution?

Hi, If you are asking for a network lock, You can unlock your phone safer and easier using unlock code. You can get the unlock code for a HTC TOUCH P3452 from http://www.unlocking4u.com/htc-p3452/rs6wp9/ at affordable cost.
Here are the steps for unlocking a HTC P3452,
1. Switch ON your HTC P3452 with a Not ACCEPTED SIM Card.
2. If your HTC P3452 asks for a PIN code, then enter your SIM card PIN and press OK.
3. HTC P3452 will ask to enter an "unlock code".
4. Enter Unlock Code we send to you.
5. Your HTC P3452 is now unlocked.

you can contact the service provider............

It's because of Network Lock,It locked to Vodafone Network,You need to Unlock it to work in other Network,You can get the Unlock code and instructions at here
http://www.onlinegsmunlock.com/nokia-e63/rs7wp9/ and Unlock it.

You have purchased a htc handset which will work only on a particular service provider like AIRTEL OR VODAFONE, 
check your default internal memory ringtone section , whether it has airtel ring tone ....

then by that service providers SIM CARD , your hand set will work.

some times dual band sim cards dont work on triband service providers.handset

Go to the GPRS Setting choose Airtel as the network manually.

the card inserted must be in wrong direction

i cannot use any other sim card instead of zong in pakistan.so how i can use more networks on samsung sght329

On Windows Mobile 6.x, the steps to configure are as follows:

1. Activate Airtel Live by sending the following SMS to 121: MASALA ACTIVE.
2. The service takes atleast 3-4 hours to get active. Restart the phone and resume configuring.
3. Tap Start -> Settings.
4. Select Connections Tab and tap Connections.
5. Select Advanced Tab, tap Select Networks button to bring up Network Management.
6. Under "Programs that automatically connect to the Internet should connect using:" drop down, tap the New button.
7. In the General Tab, type the name of the settings as Airtel Live
8. Select Modem tab, tap New...
9. Type the name of connection as Airtel Live, select the modem as Cellular Line (GPRS) and tap Next.
10. Type Access Point Name as airtelfun.com and tap next.
11. Leave username, password and domain blank and tap finish.
12. Select Proxy Settings tab. Tap "This network connects to the Internet". This should enable the next check box option.
13. Tap "This network uses a proxy server to connect to the Internet".
14. Type the proxy server as: 100.1.200.99 and then tap Advanced...
15. Tap HTTP, leave the server as 100.1.200.99 and change the port to 8080
16. Similarly tap WAP, Secure WAP and Socks, type the server as 100.1.200.99 but leave the port to defaults. These are optional settings.
17. Tap OK to close the Advanced proxy setup screen.
18. Tap OK to close the New connection screen.
19. The network management screen should now list the new connection you have created in the drop-down. Tap OK to close this screen
20. Tap OK to close the connection screen.

Now you are ready to fire your favourite browser. I have tested this on PIE as well as Opera 9.5 and it works for me.

If PIE reports "Request not authorized by the WAP Gateway", you will need to change the user-agent to anything you can think of using "Advanced Config" tool (thanks to dsixda for suggesting this). I had set it to HTCP3452_Mozilla/4.0 under Advanced Config -> Internet Explorer -> User Agent Custom Base.

I think Airtel has intentionally blocked Mozilla/4.0 user-agent on WM phones. It may be that they cannot restrict Windows Mobile based phones from accessing websites on standard HTTP. On other phones I had tried, I could not get other sites to work with the same settings.

Dear friends, before I begin with the details of Airtel Live, I wish to thank everyone at XDA-Developers for working on ROMs, fixes and the support that is being provided here.

Special thanks to dsixda for producing Onyx 3.0 because of which my HTC Touch Elfin (P3452) rocks even more.

Now regarding Airtel Live service: Airtel Live is free GPRS service that Airtel provides to its customer with a catch i.e. as per Airtel, you can only access http://live.airtelworld.com for downloading latest ringtones, games, wallpapers, videos etc.

If you call Airtel Customer Support to get Live on your HTC Touch, they tell you that it is not supported on any Windows Mobile phone and suggest you to go for Airtel Mobile office, full GPRS service for a monthly rental of Rs. 499 (USD 12).

After googling and fighting with Airtel, I managed to get the correct settings and I am able to run Airtel Live as well access most of the websites on standard HTTP protocol (SSL is not supported). Google Maps also works for me.

1. Activate Airtel Live by sending the following SMS to 121: MASALA ACTIVE.
