How can I find the cheapest prepaid SIM card for a given country?

Next month I am traveling to country X, where I would need Y minutes of calls, Z text messages and most importantly Q megabytes of data. How can I find the cheapest/most reliable SIM card for my needs?
Best Answer
For your usecase I would consider getting a phone which supports eSIM. This will at least in some countries put your in a position to sign up with a GSM operator purely over the Internet (which also means: prior to arrival) and have your plan activated when you arrive. This can be handy if you arrive in places or at times when shops are not open or hard to find.
Yet in some countries GSM operators require a proof of identity in order to sign you up, like Germany or Switzerland for example. In that case, the eSIM enabled operators will usually also allow you to do some kind of remote identification, so you can still prepare prior to arriving.
