I didn't find how to unlock 1360b, but I have a way to change sim without code:
1 - put your new sim card inside the phone, but not totally plugged (the phone don't see the sim and boot without)
2 - put the battery on but leave a little space to push forward the sim at the end
3 - boot the phone, it will say 'no sim'
4 - push the sim with something slim (like a knife)
5 - reset the phone with the hard reset code *2767*3855#
Don't let the phone turn off, or you will need to re-do the same thing again.

*#8999*8378*
To remove the SIM lock code on a Samsung E250, you would need to contact the mobile service provider that originally locked the phone. They can provide you with the unlock code or guide you through the unlocking process. Alternatively, you can try using third-party unlocking services, but proceed with caution as they may not always be reliable.
