I have the T-Mobile One Plus Promo plan. We have 6 lines on the account. Per T-Mobile's terms, customers who use more than 28GB in a month may get deprioritized. I read the information at the link below, but it's not clear to me if the 28GB is per line, or the total data usage for all lines on the plan. I understand it to mean 28GB per line, but I'm wondering if anyone has experience with this to confirm it.
On a related note, 10GB of 4G tethering is included. Again, is that 10GB per line or 10GB total for all devices on the plan?
