STK Service - SIM Toolkit - Plz Help

---

Hello all,

I have just changed my Operator SIM to a new one. Same number, but a newer version of the chip.
I have an Unlocked TMobile Wing, and now, every 45 seconds my device shows "STK Service" message at the top bar and produces a "Busy Tone".
I have already tried to find at startup directory, plus at Extensions\NewFolder directory at the registry but I could not find a way to disable this annoying thing.
Can someone plz help me with that?

Best Regards,

Did you find a solution ?
