T-Mobile’s new free line offer is its best deal yet

T-Mobile comes along all the time with new offers and deals to bribe Verizon refugees over to its network. But normally, you don't just get things for free. Most of the offers require you to port a line over, trade in a phone, sign up for a two-year plan or similar, but this new offer is a no-brainer for any existing customers, because you can genuinely get something for nothing.The new promo gives you an extra line for free, provided you already have at least two lines active with the company.
