How to Manually Change a SIM Profile Using a Smartphone?

In some cases, a SIM may remain on a profile that is not functioning correctly. A common troubleshooting step is to manually switch the SIM to a different profile using the SIM menu on a smartphone.

This can be done using the SIM Toolkit (STK) on Android devices or the SIM Applications menu on iOS devices. The instructions below outline the steps for each operating system.

IMSI Prefix to Profile Mapping

The first six digits of the IMSI identify the profile:

• 295050 – Profile E

• 311588 – Profile U

• 24007 – Profile B

• 234106 – Profile O
