LEA it's specially interested in people who use "anonymous" services, so be careful of using these services if they relate you to one of these services you will be incriminated, they will believe you are trying to hide something, I suggest you to use commonly used services ecrypting your activity and using fake data in mainstream services that way you will not arouse suspicion.
If you want to hide your activity from your ISP I suggest you to use a good VPN or Tor, if you use an anonymous e-sim to route your traffic you are more likely to arouse suspicion.
