T-Mobile today said most customers who have a service plan with two or more lines can snag another line for free. T-Mobile says this free line can be used for a phone, tablet, watch, or mobile hotspot. It will match the features of the least-expensive line that's already on the plan. For example, T-Mobile is offering two lines of the T-Mobile One plan for $100. This new deal would allow customers to score the third line of T-Mobile One at no extra charge. T-Mobile says the promotion is available to nearly all T-Mobile One, Simple Choice, and Simple Choice No Credit plans, as long as the account already has two or more lines of service. The free line is being given away in the form of monthly bill credits. Handset payments are not included. Customers who cancel one of their existing lines will lose the bill credits for the free line. Customers will need to subscribe to auto-pay to receive the free line, and it may make one or two payments before the bill credit is applied.
