Hi all, everytime i turn my phone on an app icons displayed on my phone called sim toolkit. In my apps i have 2 x sim toolkit apps (phone only takes 1 sim) and another app that says o2 sim that has the same logo as the sim toolkit app. What is it and what shall i do about it?
 
"SIM toolkit or SIM Application toolkit (STK) is a feature that allows your SIM card to perform various additional functions that are provided by your carrier or service provider. The SIM toolkit app offers various value-added services, such as utility services (providing information about missed calls, and international calls), news, jokes, customer care, astrology, caller tunes, sports scores, ringback tones, and feedback"


Should note, that not all carriers provide SIM toolkit.

It was probably there all along, though system updates can change these things.

It's not unknown for service providers to include their own apps as well when the phone is bought through them, so the O2 app is probably one that they pre-installed on the phone. Is the icon very distinctive, or completely generic? It might be coincidence that they have the same icon, or even that neither has an icon and you are just seeing Android's default icon (though that normally has an "android" theme rather than looking in any way like a SIM).
