SIM Number Setter

SIM Number Setter is a small Xposed module that invokes normally unused Android System code to set the "subscriber number" on the device's SIM card. This is the number displayed in the system settings, and used in apps such as Google Messages, as well as being available to third party apps with sufficient permissions.

The number is not always set by carriers (leaving "Unknown"), or can be lost or invalid after porting a number to a different SIM. This small app allows you to fix it, permanently, using a rooted device with Xposed.

If you don't have a rooted device, or don't want to root your main device, you may wish to consider rooting an old device, and temporarily putting your SIM into that device, using this app, and then putting it back in your main device - the fixed number will travel with it.

Important Notice: Changing the SIM number is semi-permanent: the number change will survive reboots, uninstalling this app, even switching the SIM to a different device, but can be changed again at any time using this app.
