> So tell me how this will work. Will you swap SIM cards just to post anonymously sometimes and let the telecom providers (among others) find out what your other SIM cards are through your device ID? Or will you get a SIM card from another country to use exclusively and pay roaming costs / live with a worse data plan in Austria?
> People apparently forget that telecoms providers cooperate with authorities, new legislation is planned for this too.
Also remember that as soon as you connect to the cell phone network, your location is made known. If you ever slip up and use your personal and private sims in a more private place, you are likely to get caught. Coupled with other potential identifier leakage (like device id as you mentioned) the opsec bar is high for this use case.
