It’s so weird to me that in the US you pay to receive messages or calls. Where I live the sender pays, or the caller pays. It doesn’t cost to receive. Plus you normally get unlimited messages anyway, like even a approx US$10 a month plan will have unlimited SMS included and like 200 minutes of outbound calling, plus data.
If you’re paying for messages received then people can send you unsolicited messages and it costs you money?
