here are actually two codes that you can actually use to reset the password. Below are these codes. Please dial them up and have the problem solved.

• *2767*3855#
• *2767*2878#

This mean the security code will be reset to 0000. This will allow you to format the phone easily.

This will be displayed only if your sim is inserted incorrectly or the sim is damaged. Please check this and if problem continues then please check your activated profile. If you have activated flight mode then your mobile will show no sim mode.
after this if problem presist please ask again .
bye. .

remove your sim card and insert it again

first ask your service provider for the PUK numbe. after getting the PUK number, go to security settings and choose change PIN, it will ask for old PIN number, try a random number and then it will show, sim blocked, please insert PUK number.
insert the PUK you got from your operator and then you will be able to change your PIN and hence remove it.

hi tsegembo and welcome to fixya,

If your sim is the problem you should bring it to the network company to reset the sim.
thanks and have a nice day

It may be due to network lock,
you can unlock it and switch over to another network , you can get unlock codes here http://www.theunlockarena.com/samsung-s5233a/rs13wp9/

you need to specify the country and network provider

Hi,when a phone displays insert Sim, it means that the phone's Sim tray where Sim card are inserted in bad and can't make the Sim card display again .You'll need to replace Sim tray.

Take care.

have you looked to see if the phone has got gprs settings for your network? if it has not got to the networks website where you should be able to send the settings to the phone
