T-Mobile might be giving away free lines to some lucky customers, according to a report from The Mobile Report. The carrier will be targeting certain customers to add a new line to their account, and the amount will be credited back as a monthly bill credit for as long as the customer maintains eligibility. This offer is for Bring-Your-Own-Device (BYOD) only, and it’s not clear who is eligible for the offer. Customers interested in finding out if they are eligible should reach out to T-Mobile directly or visit one of their stores. The use of the words “targeted customers” implies that free lines won’t be doled out randomly, and customers who already have free lines might not be eligible. Support representatives will determine eligibility by checking the account’s segment’s page, so if your account says “BYOD Line Discount ID230289 – Inactive,” you will not be eligible. The deal will likely not last forever, so interested customers should act quickly.
