Earlier this week, news broke that T-Mobile was testing a new 36-month installment plan that would let users pay off pricey smartphones over a three-year period instead of the usual two years. Those plans are officially launching this Friday.

Full details aren’t available yet, but T-Mobile’s announcement notes that the Samsung Galaxy S9, Galaxy S8, LG G7 ThinQ, “and more” will be eligible for the plan. Combined with the company’s trade-in offers, customers could pay “as little as $10 a month for your new smartphone.” While that number may be a bit optimistic, if you’re looking to save on your monthly bill, it’s probably not a bad option.

T-Mobile’s not the first to offer longer plans — AT&T has 36-month and 30-month options too— but the fact that these plans are cropping up speaks to how expensive big flagship phones have gotten with $1,000-plus price points.

Unfortunately, it doesn’t look like Apple’s latest iPhones are included in the 36-month plan for now. T-Mobile’s support page says that “36-month EIP terms may be available on select devices,” so it seems that it’ll only be coming to a few devices for now.
