The Galaxy A51 is without a doubt one of the best all-around smartphones you can get on a relatively tight budget nowadays, an assessment with which more than 6 million people worldwide have agreed in the year’s first quarter alone, reportedly making the mid-ranger the most popular Android model of that three-month period.

For a presumably limited time only, the nation’s largest wireless service provider has the black-coated Samsung Galaxy A51 on sale at… $0. Naturally, the huge $400 discount comes with a few special conditions and strings attached, but we’re not talking about anything particularly convoluted or hard to claim.

There are no device trade-ins or number port-ins involved, and you can even choose between getting the handset at its $399.99 retail price or technically committing to paying $16.66 a month for two years on an installment plan. Either way, your savings will be applied as equal credits to your bill over a period of 24 months after opening a new line of service on an unlimited plan.
