I am in the US. I pay $80 a month for TWO phones. My plan provides unlimited calls, texts, and shared 2GB of 4G data. When my data runs out, my data speeds go to 100kb/s.
You need to look at prepaid options. All major carriers have those. They are not bad if you like in or around a metropolitan area.
TMobile -> Metro PCS
Verizon -> Visible
ATT -> Cricket
I'm on a T-Mobile 4 line plan at $30/line. Unlimited everything except I think it deprioritizes data over 50GB/month/line. But I've never exceeded 10GB/month yet.
Does that include phone payments at all? Because it sounds like you’re getting a not so great deal. I’m also in the US and pay that much for unlimited everything on 2 phones
