"SIM Tool Kit: Error in application" pop-up always shows on Lenovo Vibe K5 I have a Lenovo Vibe K5. The phone screen always shows a pop-up message saying:

SIM Tool Kit
Error in application


How to fix this issue?
Check if both SIMs are activated or not. If not, kindly recharge and activate it. The pop up will not come.

Ex. I got this error due to Airtel SIM and my SIM's incoming outgoing was already stopped. I also got the same error, also tried all things posted on internet and YouTube. I recharged RC 35 and it automatically resolved.
