Why Apple Requires a Cellular Account Through a Big Three Carrier to Lease an iPhone

Monday, 3 August 2026

Following up from last week, when I asked:

When you lease an iPhone through Apple Upgrade, you need a cellular account on one of the big three U.S. carriers: AT&T, T-Mobile, or Verizon. That kind of stinks, and I’m not quite sure I understand why. You’re leasing the iPhone through Apple and Klarna, not the carrier, so I don’t know why Apple cares. If you know why, shoot me a message and explain it. Is it just a simplistic credit-risk evaluation, where prepaid plan-holders and MVNO users in general are viewed suspiciously?

I got a slew of messages about this. Credit-risk assessment is seemingly part of it. There’s a lot of fraud in iPhone purchases specifically and cell phone service generally. The big three carriers do a significant amount of risk assessment before letting you open a new postpaid account; that you have an active account with one of them is a signal that you’re not trying to lease an iPhone using phony credentials in order to sell it.

But the bigger reason is the complex nature of the contracts between Apple and each of the big three carriers. A reader who worked on the carrier team at Apple for a long time (but left a few years ago) wrote:

In response to your question on why Apple would only offer iPhone on the “Big 3” for the new Upgrade Program: Every year, the Carrier Teams at Apple negotiate a deal/program (hundreds of millions of dollars) with each of those Big 3. In return for those dollars, Apple will make concessions exactly like this (or similar.) This is also why, for example, their logos appear more prominently or are the only ones called out on signage, commercials, etc… Although they really aren’t threatened by MVNO’s (the ones they don’t own) or regional carriers, it’s more like Apple is selling it as part of a package deal that’s exclusively offered to its biggest and best “tier 1” partners. It also acts as a carrot to perpetually try to motivate smaller partners into behavior Apple wants.

This might change — some of the bigger MVNOs are trying to work their way into “tier 1” (or maybe create a new “tier 1.5”). But for many years now, part of the co-marketing agreements between Apple and the Big Three is Apple agreeing to require a postpaid account with a Big Three carrier for all “special” iPhone financing deals, including the old iPhone Upgrade Program and the new Apple Upgrade leasing.

One interesting exception is that Boost Mobile is included alongside the Big Three for Apple Card Monthly Installments (ACMI), a program that offers 0% APR on certain products if you pay for them using an Apple Card. From the ACMI small print:

In order to buy an iPhone with ACMI, you must select one of the following carriers (prepaid carrier plans are not supported): AT&T, Boost Mobile, T-Mobile, or Verizon. An iPhone purchased with ACMI is always unlocked, so you can switch carriers at any time, subject to your carrier’s terms.

So perhaps some of the bigger MVNO carriers might work their way into Apple Upgrade — but if they do, it sounds like they’ll need to pay Apple for the privilege.

With regard to fraud, a former Apple Store retail employee wrote:

I left in 2019, but I’d estimate on some days a double digit percentage of in-person phone sales were fraudulent.

This behavior absolutely exploded when you started to be able to do carrier financing in the store. They had stolen the identity of a legit account holder, come into the store with the info needed to access the account. They always wanted the highest end phone, and would pay the sales tax due at time of sale in cash. Never wanted any accessories. Never wanted to open the box or set up the phone.

As bad as it was with the activation requirement, it would be way worse without it. I believe it’s gotten a lot better, and the carriers have more advanced systems in place to detect and deter this behavior now. But ultimately, the carriers ate the cost for millions of dollars in devices they never got paid for.

I suspect that reader is correct that Apple, in collaboration with the carriers, has cracked down on this.
