My gt-s 5570 doesn't send messages after it was unlocked

You need to recalibrate your touchscreen. If the screen can not be recalibrated, then it needs to be replaced. Please see this link on how to recalibrate your touchscreen:

Use the Nuvi 14xx procedure

Try to uninstall the Lexmark driver and download an updated driver online. Just go to http://bit.ly/UmL4pl and choose the operating system of your computer.

If it doesn't help, check your print spooler if it's running. To do that, on your computer, click on Start > Run > type in Services.msc > OK > look for Print Spooler and make sure that it's started.

Hi generally this problems occurs due to incorrect message settings so please note >.>>MESSAGE SETTING >>MESSAGE center number(should begin with the pre-fix of +country code followed by specific center number)...>>MESSAGE SENT AS (should be "TEXT").....If you found all the settings are found correct contact your sim card provider/call to customer care.Good luck.Thanks for visiting fixya

try to full reset by *2767*3855#

FORMAT IT AND ENJOY

Menu > Messaging > Options > Settings > Text Message > Message Centres (the very top option, above centre in use) > Options > New message centreIf the above post doesn't help, Restore the factory settings. Dial *#7780# on the phone, I think it retrieves the message centre number through the sim card with this.Usually in some cases a format of phone and mass memory is needed if it doesn't work. So go for *#7370# and see

How to enter the Unlocking Code for a Sony Ericsson Model phone General Information about your Sony Ericsson unlock code
When you receive your email with your unique Sony Ericsson unlocking codes, you may see there's actually more than one code, as some models require more than one code to unlock them fully. However, for simplicity, we do aim to send you a single unlock code, which will be your network unlock code (known as the NCK).

(See below for more details about code formats and more - Please read all before you start unlocking?)



Option 1 - Sony Ericsson Models
1. Turn on the phone without SIM Card in it
2. Press the 'left arrow' or joystick left once
3. Press the * (Star) button twice
4. Press the 'left arrow' or joystick left once
5. The phone will display one of either messages saying 'Personalize with MNC2' or 'Personalize with MNC3'
6. Wait approximately 5 seconds.
7. The phone will display 'Network' and a picture of a closed padlock.
8. Press Select.
9. The phone will display 'Unlock (Net) 5' and 'NCK:'
10. You can now enter the Unlock Code provided.



Option 2 - Sony Ericsson Models
1. Turn on the phone without SIM Card in it
2. Press the 'left arrow' or joystick left once
3. Press the * (Star) button twice
4. Press the 'left arrow' or joystick left once
5. The phone will display the message 'Personalize with MNC2'
6. You can now enter the Unlock Code provided.



Note for options 1 & 2
- When doing the first 5 steps above you'll need to do it quite quickly. - If your phone has a joystick 'JOGDIAL' you must press the 'down arrow' instead of the 'left arrow' in steps 2 to 3 above. By 'Down Arrow' we mean move the joystick down

Quick Glossary
NCK = Network lock
SPCK = Service provider corporate lock
SPK = Service provider lock



Code formats you may receive for Sony Ericsson models:
Wherever possible we'll try and send you just a single unlocking code to unlock your Sony Ericsson.
However for certain models we may need to send you more than one code, even if you don't use them all.

It would be a sting of codes as per this example:

CCK: 0984118391686835 or 0984118391686835
ESCK: 0000000000000000 or 0000000000000000
NCK: 4176979876474847 or 4176979876474847
NSCK: 3908320398047435 or 3908320398047435
PCK: 2061751224321908 or 2061751224321908
SPCK: 9960493992337231 or 9960493992337231

Note: The NCK (Network unlocking code) is the main and usually the only one you'll need.



Please note:
- If you see the message 'NCK: (0)' or 'Not Allowed', this means the phone is hard-locked. The phone cannot be unlocked because there has been more than 5 wrong unlock attempts.
- If your Sony Ericsson has a Joystick, then you must press the DOWN Arrow instead of the LEFT Arrow. DOWN Arrow meaning Joystick downwards

The OSD can be enabled or disabled by pressing and holding the Menu button on the front panel for 10 seconds. If the OSD is locked, the warning message OSD Lock displays for ten seconds.

* If the OSD is locked, press and hold the Menu button for 10 seconds to unlock the OSD.
* If the OSD is unlocked, press and hold the Menu button for 10 seconds to lock the OSD.

I have the same problem using an unlocked Treo 650 on O2(UK).
One thing you need to do is make sure that the Message Centre Number is set correctly for the SIM network you are using. Get the MCN from the internet, then on the Treo Messaging > Menu > Options > Preferences > Network > Manual > Edit to check/set the MCN.
