I’ve had ATT prepaid for me and the other 3 in my family and with all of us it’s about $100/month. We don’t need unlimited since everyone is almost always connected to wifi. Also they roll over unused data up to 30gb. The wife and I have 25gb plans and the kids have 5gb plans and we can use those for tethering too. Been on it for over 4 years now…
Maybe a dashboard might help? Gethomepage.dev works really well for me.
