Hi visit Mobileunlocksolutions.com to unlock your mobile from sim lock .Here they ask you the network name to which your mobile is locked and the IMEI number of your mobile.Then at last they deliver you code to remove sim lock in your mobile.

If you have forgot your password, then flashing the ROM memory of your mobile in a mobile service center is the only way. Before that try with the default password of your phone. Refer your phone manual for it. Try 0000/00000/12345/1234/1111/11111 (any one of this may be default)

Hi,

If you need the PUK ( Personal Unblocking Key ) for your phone, you will have to contact your mobile phone service provider.

PUK code is related to the SIM card you are using. So, kindly call the Customer support of your mobile service provider and they will provide you with the PUK code.

Also, entering a wrong PUK code ten times in a row disables the SIM card permanently. So, please be careful while entering the PUK code.

Hope this solves your problem. Thanks for using FixYa.

You can get it from Samsung Service Center, if you don't want to change its firmware. Custom Mercedes Accessories

recharge your batery then press the off baton for 5 seconds or 10.

Delete some unnecessary files in your phone memory like images and videos. Go to your phone gallery and delete some of those. And if you want to use the memory card as phone message storage then go to Messaging - Option - Settings - Other and then Memory in Use, select your memory card.But if your phone is infected with a virus then you need to format your phone. One sign of infection is your phone keep sending a message randomly from your contacts without your consent.Use these code and enter it to format your phone:*#7370# and then the default code is 12345Take note: Make sure you back-up your contacts or any other important inside your phone.Hope I make it clear and does makes sense

Try to reinstall Calendar. If that doesn't help do a Custom Reset (you'll lose all personal data though).

just do not delete them

Go to Settings-Application settings-Call-All Calls-Auto Reject-Reject List then deselect or remove the number from reject list.

This will reset the phone's settings to factory default. Use this at your own risk:

1. Switch off phone.
2. Remove the sim card.
3. Turn on the phone.
4. Type *2767*2878#
5. Use 00000000 when it ask you again for the phone lock code.

You can get the unlock code for your Samsung D900 from your service provider or from reliable online sites like classicunlocking.com .For unlocking instructions you can visit mobileunlockguide.com , here you can get simple and step by step instructions to unlock your phone!!!

It would appear your phone is not YouTube enabled. Sorry.

you have to dial the freephone number and have the sim card registered then you will have full service ;-)
