Every “unlimited” mobile plan I’ve heard of has fine print that says it slows to a crawl after some amount. I don’t know if the real limits are different in practice, so I was asking about that.

These days you just get “deprioritized” instead of a hard throttle on most unlimited plans after reaching the amount. Deprioritized means the network treats your data as less important so if the tower gets congested it’ll slow down otherwise it’s still full speed.
