In Spain I pay 19€ for unlimited calls (no SMS included), and 23GB of data and for 2€ more I can add another person to share my data plan.
I am in [redacted] and my 50GB mobile data (unlimited calls and texts) is part of my €55/month home internet package (which includes 1Gbit fiber internet, land line and a TV box + package not that I care for that).
America has crazy expensive prices for mobile plans!
