Write some Software

Hello everyone! I need application for Lenovo tablet which is running on windows 10. This application must be hidden and working in background all the time. When you finish it, i will try to put it in system, to run on startup and not to be able to delete. Application is about checking SIM cards. Tablet has one slot for sim card. I need application to check every time user inserts sim card, which sim card is in tablet and if the sim card isn't from the mobile operator(example Vodafone, T-Mobile, Verizon) which is only allowed, the application should disable tablet, and by disabling I mean, pop up window where user must insert 8-digit password(password should be unique for every tablet, like: IMEI*3 and last 8 digits is password) to be able to use telephone normally. If it doesn't know password, the user shouldn't be able to use telephone, so I need somehow to prevent user is using telephone if he doesn't have password or the SIM card inserted from the operator who is allowed. So, it is about locking tablet to certain telephone operator, and if the sim card which is inserted in telephone is from allowed telephone operator, application should just let user use telephone normally. If you have any additional questions, I am here to answer. I will explain more detail when we get in touch. Thank you!
