This guide will show you the steps to prevent CSC from changing when you use a different SIM card. Country Specific Codes, more popularly known as CSC, are unique for each region and/or carrier. So if you have imported a device from outside, then it is recommended to change the CSC to your home region. This is because even though you might still continue to receive OTA updates of the foreign country, but it might end up breaking the bandwidths that your home carrier supports.
Under similar circumstances, if you put in a SIM card of another carrier, then it might end up changing the CSC code stored in the MSP Code Preconfig. Fortunately, you could stop that from happening, in other words, prevent CSC from changing when you use a different SIM card. Follow along.
