I think I'm just being paranoid, but I haven't been updating the carrier settings because I recently went to upgrade to an iPhone 7 and they said I have an expired plan and I'd lose it if I upgraded and end up paying an extra $30 a month for the new plan. I'm worried if I click "update" it might change the plan without my knowledge. I am probably trippin because I would think I need to sign a new contract or something, but I'm wondering if someone might be able to enlighten me. Thanks
