T-Mobile Offering Three Lines of Unlimited Data for $100 for Limited Time

by

T-Mobile today announced that, starting March 1, new and existing customers can activate three lines of T-Mobile ONE with unlimited data, talk, and text for $100 per month after bill credits. The plan usually costs $100 per month for two lines, and $140 per month for three lines, so the third line is essentially free.

T-Mobile is also offering an additional line for free to existing customers with two or more voice lines, including T-Mobile ONE and older Simple Choice plans. There are virtually no strings attached to the deal, which is likely an incentive to keep customers from switching to new unlimited data plans at AT&T and Verizon.

The offer is available for a limited time only, but T-Mobile said customers who take advantage of the promotion now will be able to keep the free third line for as long as they have qualifying service and remain in good standing, or until they make changes to their plan. Prices are based on AutoPay.

Competition is good! Imagine the prices if AT&T and V were able to gobble up all the smaller carriers.

I'm fairly happy that AT&T's attempt to buy T-Mobile was blocked a few years ago and we still have some vestige of competition among the cellular giants.

You can probably ask them to waive it.
I switched last weekend, if you have a Costco membership they waive the SIM card fee.
