Billing period and contract term are different
All Personal plans on this page use monthly billing. Monthly billing does not always mean a one-month contract. GSM 1–5 have a published one-month minimum contract. GSM 6 includes unlimited 4G data and has a published 12-month minimum contract.
Confirm coverage, activation, number transfer, cancellation terms and any fair-use conditions before ordering. Do not cancel your existing service before your number transfer is agreed.
