    at first I was loosing reception after about 1 min of talking, then things gradually became worse, as the phone would put out a buzzing noise while playing music, then it kept on freezin up, now when I try to turn it on I get the white screen, then nothing. Phone is 6 months old.

    tried new sim, while I was gettin reception problems, but no luck.

Very common. you're not alone... ;] Hopefully your problems will get fixed with the latest firmware, there are all sorts of firmware bugs like this. You can take your K750i to an authorised Sony Ericsson Repair Centre and they will update it for free for you, providing its still under warranty. Or you could update it yourself via the sony ericsson website - Hopefully your problems will have been fixed with the latest firmware, there are all sorts of firmware bugs like this.

Good luck

Just take out your sim card and wipe it off. It should work after that

Inactive Sim and Signal


this is happening to mine aswell. i have had it for nearly 8 months it had a good period of no problems bout 6 months after puchasing. However just today it has been saying inactive sim and re-setting itself for the last 45minutes. i blamed it on a loose sim card holder but i tightened that and it is still not working. the only way to fix this is to complain like a ***** and get your money back.

My SGH-T629 came from the U.S. how can i make it capitable with the sim card in the phillipines


A. Turn on phone with full battery and non-T-Mobile SIM in place.
Allow phone to completely boot up to Wrong SIM screen. B. Enter from Wrong SIM Screen *#7465625# to confirm lock status C. Scroll through Interrogate Screen 1. Network lock - Active (this is the one you'll be deactivating)
2. Subset lock - inactive
3. SP lock - inactive
4. CP lock - inactive
5. SIM Card lock - inactive
6. Activa lock - inactive
7. Auto network lock - inactive
8. Auto subset lock - inactive
9. Auto SP lock - inactive
10. Auto CP lock - inactive
11. Auto SIM Card lock - inactive
12. Phone lock - inactive D. Push "C" button under navigation button to clear Interrogate screen back to Wrong SIM
screen E. From the Wrong SIM screen enter the following: *7465625*638*00000000*00000000# Those are two series of eight zeros. The phone will not show the zeros but will show dashes in their place. Phone may make a small tone and at the bottom of the screen it will read "Network Personalized" or perhaps "Network Already Personalized" F. Now input the following from whatever screen shows up: #7465625*638*00000000# (again this is a series of eight zeros) Phone may make small tone and will read "Network Lock Deactivated" G. Turn off phone
H. Re-start the handset and allow it to reboot.
J. Enter from Standby Screen *#7465625# to confirm lock removal status K. Scroll through Interrogate Screen 1. Network lock - inactive (note that this lock is now inactive)
2. Subset lock - inactive
3. SP lock - inactive
4. CP lock - inactive
5. SIM Card lock - inactive
6. Activa lock - inactive
7. Auto network lock - inactive
8. Auto subset lock - inactive
9. Auto SP lock - inactive
10. Auto CP lock - inactive
11. Auto SIM Card lock - inactive
12. Phone lock - inactive
That's it. Your phone is ready to accept SIM cards from just about any GSM mobile telephone service provider in the world. If you received a "wrong password" message you will need to insert a working SIM and reset the password to the default 8 zeroes "00000000". After that you may try this process again and it should work.

From orange to O2


you could try this

By doing the reset (1st temp) you will lose all your
data ie contacts, messages, photos, videos etc etc so
back them up on your pc first.
Take out your sim card and follow the instructions below :
1st temp. put this number in the keypad
*2767*3855# let it reboot(restart)
now its ready for permanent.
Put in a sim card of a network that the phone won't
except and follow the instructions below.
( If you can't type anything with a locked sim
card inserted just take it out and do the next
step without a sim card in the phone)
Don't worry if your screen shows - - - - - - - when typing
it is supposed to do this.
Permanent.
ENTER :
*7465625*638*00000000*0000000
0#
NEXT ENTER
#7465625*638*00000000#
AND THEN *#7465625# to check the locks....all locks are
inactive...these are all the locks...
network lock - inactive
subset lock - inactive
sp lock - inactive
cp lock - inactive
sim lock - inactive
activa lock - inactive
phone lock - inactive
auto network - inactive
auto subset lock - inactive
auto sp lock - inactive
auto cp lock - inactive
auto sim lock - inactive
Enjoy !
This procedure does not change your imei number at all

hi
Try with all the code to see whether you can get one to unlock your phone. If all still cannot help then you can only contact Samsung Support for help. I hope these information below at least can give you some hints:

Note try codes which help direct unlock for either SIM Lock or Security Lock first before try other codes

*7465625*746*Code# = Enables SIM lock
#7465625*746*Code# = Disables SIM lock
*2767*2878# (Temporary Unlock)
*7465625*638*00000000*00000000# (Set Code)
#7465625*638*00000000# (Clear Network Lock)
*#7465625# (Verify the network lock is “inactive”)

*2767*3855#
*2767*3855# - FULL E2P RESET
*2767*2878# - CUSTOM E2P RESET
#*7337# - UNLOCK
*2767*688# - UNLOCK
*#0523# - CONTRAST
*#9998*523# - CONTRAST
*#8999*8378# - Service Menu (X100)

First with different carrier SIM in phone at WRONG CARD screen ENTER on the keypad
*2767*3855# (wait 10-15 seconds) phone will reboot(restart)
When phone completes reboot ENTER
*7465625*638*00000000*00000000#
NEXT ENTER
#7465625*638*00000000#
AND THEN *#7465625# to check the locks....all locks are inactive...these are all the locks...
network lock - inactive

sp lock - inactive
cp lock - inactive
sim lock - inactive
activa lock - inactive

auto network - inactive
auto subset lock - inactive
auto sp lock - inactive
auto cp lock - inactive

White screen on my phone sony w550i
