Dear, I had LG RD 5130 Handset which was working fine till few days back. But now it is not working as my service provider has changed the switch and migrated to new exchage having different settings. That's why I need solution to change those parameters. Kindly guide me how to change the parameters like- Country Code, Mobile Network Code, Primary channel A, Secondary Channel A, Primary Channel B, Secondary Channel B and Home SID/NID.
