Hi, You can get the unlock code for a Sony Ericsson Xperia Arc S from www.onlinegsmunlock.com at affordable cost with easy unlocking guide. Good luck mate.

Hi,
This is a software issue.
Please take it to an authorized service center and downgrade the software.

for sending text messages :
1.go to your message settings and check the message center number to see if it is correct
2. call to your network operator customer care
3. request the message center number...
4.note it down
5. go to message settings>message center number
6. insert the number which is noted by you and save it

this solves your messaging problem ...
Good luck

pin =PERSONAL IDENTIFICATION NUMBER which fixya does not have or access to your accounts if bought this new you can try your provider for assistance with proof of ownership --if bought used can try provider

try to check if the vibrate of your phone is turned on....maybe it's turned off...check the settings... :)

First, try this:

1. From the main home screen, tap menu
2. Tap Settings, then Privacy
3. Tap Factory data reset
4. Tap Reset phone
5. Enter your password if required, then tap Erase everything to confirm

If that doesn't work, or if your phone is frozen:

1. Turn the power off. If your Sony Ericsson Xperia X10 is frozen, pull the battery out and reinsert it
2. Hold the Left and right buttons located beneath the display
3. Press and release the Power button
4. Follow the on-screen instructions to hard reset your Xperia X10

All data including third-party applications will be deleted from the Sony Ericsson Xperia X8. Once the wipe is complete, the phone will reboot to its factory fresh state.

The password is user defined, try the second method if you did not set a password.

Good Luck!

Points to note before you start...
You use this APK at your own risk! I recommend you have a backup, or at the very least a strategy to return your device to stock should the unthinkable happen.
I have tested ONLY on the devices listed below! Extra extra caution is suggested if you want to try it on something else!
Your device needs to be rooted in order to run this process.
If your device is Android 2.3.3, only the required files are installed.
If your device is Android 2.3.2, the build.prop is also edited to 'spoof' the newer version.
As part of the install process, your Google accounts will be wiped and you'll need to re-set them up when you reboot.
Devices i've tested this on...
Samsung Galaxy S II (fully working)
Sony Ericsson Xperia Play (fully working)
Sony Ericsson Xperia Arc (rear camera only)
Let me know if you try it on something else and it works!

How to use...
Download the APK linked below (please do not mirror this elsewhere)
Install on your device in the usual way
Run 'Video Talk Installer' from the programs Launcher
Device will reboot
You can now uninstall the app (you only ever need to run it once!)
And here it is...

Hi there,
Though I firmly believe that the best guide is to just USE the device, I do understand not knowing how to do a certain thing and trying to find it in the user's manual.
I've found a copy of the user manual, I'm not quite sure on the detail:

Of course you can always go directly to sony for this information as well:
