Ok. My little niece got ahold of my phone and changed the password on my messages so i cant text or nothing. So how do it unlock it?

It is very simple to Unlock your Samsung Solstice SGHa887 by entering Imei Unlock Code . you can get your Mep Unlock Code for Samsung by third party or your network provider.
third party give your Imei Unlock Code within hour. but your network provider take time to give you Imei Unlock Code. and charge huge amount. you can buy Samsung Imei Unlock Code from third party. they will charge little amount.
i hope this will help you.

Hi, You may contact to your service provider Samsung Solstice SGH-a887 Unlock Code, they can open up all networks for you where you want to use your phone. You may visit Samsung Unlock Code, they will provide you an accurate code with easy to follow instructions on how to unlock code.
Hope this is helpful.

Thanks.
