By phone plan I don't mean for the actual physical phone (which people might get as monthly payments if it's an expensive model) but for calls, messages, data etc. So basically your phone bill.
There was a similar thread on the r/AskAnAmerican where many people said they pay more than a 100 dollars per month and to me that's honestly crazy. I have a contract for three different phone numbers (all on same carrier) where I get unlimited calls, unlimited SMS and 15GB mobile data in all EU countries (no roaming fees) and I pay 28 euros. I also think it's a bit too much but I'm too lazy to hunt down a cheaper offer.
How much people pay in other European countries?
