Hot on the heels of the announcement of Mobile Without Borders, T-Mobile is apparently prepping a big new plan to go along with it.

Responding to Twitter criticism about T-Mobile’s 4 lines for $100 plan doesn’t included Mobile Without Borders, T-Mobile COO Mike Sievert has teased that his carrier is prepping an “EVEN better promotional plan” that will include Mobile Without Borders. Sievert also teased the plan to CNET, describing it as “big, bold, and cool.”

@jamaal192 @JohnLegere We'll do you one better. We plan to launch an EVEN better promotional plan which will qualify. Win win stay tuned!

@apkdownloads @JohnLegere It works. Single charge of $10/month for whole fam. New promo plan starts next week that's even better includes it

This new promo plan is expected to launch this week, and while an exact date hasn’t been give, it could launch on July 15 alongside Mobile Without Borders. Because Sievert responded to people using the 4 lines for $100 plan, it’s possible that T-Mo’s new promo plan could be a family plan too.
