Switching to a new carrier can be stressful. You want to test out the network at all of the places your normally visit, you've got a new bill to look over, and you may have a new device that you're testing at the same time. A new Sprint promo aims to make sure that you're happy with your new carrier, and if you're not, you'll be able to leave with no issue.

Sprint today launched its 100% Total Satisfaction Guarantee. With it, new customers and existing customers adding a new line can try out Sprint for 30 days. If they're not totally satisfied with their experience, Sprint will refund the phone costs including device price and down payment, service charges, and fees.

Alongside its new 100% Total Satisfaction Guarantee, Sprint is rolling out a switcher deal. Customers who switch to Sprint can get up to $650 to cover their switching fees and another $250 in the form of a prepaid Mastercard card when they buy an iPhone XS or iPhone XS Max.

If you've been thinking about making the jump to Sprint, now seems like a good time to do it with the arrival of this 100% Total Satisfaction Guarantee. Not only can you get your switching costs covered, but you can also get reimbursed for your phone and service costs if you end up deciding that Sprint isn't for you.
