SIM cards don't have apps on them! They just have the IMSI, a key, some prior data about which tower it last connected to, and some miscellaneous data (such as a PIN number, etc), together with a data area that's used exclusively to store a limited number of contacts and SMS messages. This was useful when phones (think Nokia bricks) didn't have much (or any) storage capacity.
Carriers can, however, create their own firmware images that contain their crapware apps, which is why they're uninstallable.
- blibble 13y agoof course they can have apps on, every single SIM I've ever had has had operator specific applications on them: https://en.wikipedia.org/wiki/SIM_Application_Toolkit https://en.wikipedia.org/wiki/SIM_Application_Toolkit

- dobbsbob 13y agoEvery SIM sold in my country has an app for tracking you that responds silently to type 0 SMS spamming which law enforcement uses
- kintamanimatt 13y agoWhich country is this?
- dobbsbob 13y agoAny country that has that enhanced 911 law passed so they could quickly find emergency callers, so almost every country. Germany, US, Canada, UK ect. EFF reported German LE used silent sms over 400,000 times in 2010 to track suspects, activists/anarchists, anybody they want don't need a warrant
