If I use the ATT Unlimited Data Starter plan, what happens if one of the persons on my plan tethers his phone? Specifically:
1. Is there a monthly limit?
2. What happens if he exceeds it?
3. Is there a charge?
4. If speed is ramped down, does it only affect his phone or everyone else on the plan also?
5. If speed is ramped down, is it slowed for only tethering or is it slowed for non-tethered use also?
Thank you for your time and efforts to read and respond.
