Introduction
This repair is typically needed if you're switching carriers, upgrading your SIM card, or experiencing connectivity issues like dropped calls or trouble accessing mobile data. Replacing the SIM card can also resolve problems such as an unrecognized card or service errors.
This repair only requires any kind of prying/opening tool, the iFixit Opening Tool was used in this guide. To replace the SIM card in your Casio G’zOne Commando 4G LTE, you’ll first need to remove the phone's battery. Keep in mind that removing the battery will reset the phone temporarily, so make sure you don't have any unsaved work or data before beginning disassembly. Additionally, it's important to handle the SIM card with caution to prevent damage. Follow this guide for a smooth and effective repair process.
