How does SwipeCaddy pick the best card at T-Mobile?

We rank each card by its reward rate times a conservative cash value of its points or miles — no inflated transfer valuations — and apply T-Mobile's card-acceptance rules, so the "best" card is one you can actually use at the register.

Do I really need a business to earn 5% on my T-Mobile bill?

To get the top rate through the Chase Ink Business Cash Credit Card, yes — it is a business product and the application asks about your business. Many people qualify as a sole proprietor with side income, but if that is not you, take the Wells Fargo Autograph Card at 3x with no annual fee and stop there. The gap between 5% and 3% on a wireless bill is a couple of dollars a month, not a reason to invent a business.

Is the Max Cash Preferred Card worth chasing for a phone bill?

Only if you can actually get it and the numbers line up. It pays 5% on cell phone providers when you select that category, but the 5% covers just the first $2,000 of combined quarterly spend across both of your picks, so a phone bill competes with whatever else you chose. It is also sold only through partner banks and credit unions — there is no national application — and it charges a 3% foreign transaction fee, which matters if it would otherwise be your travel card.

Good to know at T-Mobile

A phone bill is a fixed, recurring charge, and it lands in one of the few everyday categories where the honest answer is a business card. The Chase Ink Business Cash Credit Card tops the T-Mobile ranking at 5% on phone and internet services, on up to $25,000 of that spend a year. For a household paying for two or three lines, that cap will never bind — it was written for a company buying service for a whole staff, and a normal wireless bill uses a small corner of it.

If you do not have a business card and do not want one, the Wells Fargo Autograph Card is the strongest consumer fallback here at 3x with no annual fee, and the U.S. Bank Business Triple Cash Rewards Visa sits at the same 3% on the business side. Going from 5% to 3% on a bill of roughly $1,200 a year costs about $24 in rewards, which is worth knowing before you open a business account you would not otherwise use.

There is one more path worth naming. The Max Cash Preferred Card pays 5% on cell phone providers, but only if you picked that as one of your two 5% categories, and only on the first $2,000 of combined quarterly spend across both picks before the rate drops to 1%. Our ranking shows its best case, assuming you made that selection. Two caveats sit on top: the card is distributed only through partner banks and credit unions with no national application, and it charges a 3% foreign transaction fee.

The math

Spend $150 a month at T-Mobile and Ink Business Cash Credit Card returns about $90 a year at our valuations — a flat 2% card returns $36.
