T-Mobile’s upcoming T-Mix plan perks might not be as flexible as you think

TL;DR A new comprehensive leak suggests that T-Mix plans could launch between October 13 and October 16.

One major expected limitation of T-Mix plans is that perks cannot be changed outside a fixed quarterly window. Since phone deals also require perks, this could potentially block subscribers from certain device upgrade promos.

T-Mix plans could come with an uncapped $10-per-line AutoPay discount and launch with a four-lines-for-$100 deal.

Following initial leaks detailing how T-Mobile’s T-Mix plans work, a fresh batch of backend details sheds light on previously unknown limitations and bonuses arriving with the carrier’s overhauled postpaid lineup.

According to a comprehensive breakdown from The Mobile Report, the backend systems powering T-Mix are now fully operational, pointing to a potential launch between October 13 and October 16. The plans seemingly mirror T-Mobile’s Experience tiers on core network features, taxes, and 36-month device installments, but diverge radically in how perks and phone upgrades are handled.
