Yeah.... that one you should get reimbursed for. I dunno how it works for their service but on Verizon there's a primary phone and the other phones share the plan of that phone. So that mistake can't happen

One of you would have an account. And both phones would be under that account. One number being the primary. The other being activated off that. Have to give them texting individually. But at least the plan rate doesn't suffer any wonky retardedness
