How are you feeling about your current carrier? Looking for a change? Want to get some money for making the switch? Sprint's got the right deal for you today. It's called a "Bring Your Own Device" deal where you don't even have to give up the phone you're currently using or pay for a phone you don't need. Just take your phone to Sprint, make the switch and sign up for an Unlimited plan, and Sprint will give you a $300 prepaid Mastercard. It's really as simple as that. In addition to switching over, the deal's only other requirement is using the link to register online.

Sprint Unlimited Phone Plan and $300 prepaid MasterCard

You'll need an unlocked phone that works on Sprint's network to start. Then switch it over to an Unlimited Plan (starting at $35) and register online, and you get a $300 prepaid Mastercard after 90 days.

Get up to $300 back

So in order to switch your phone from Verizon, AT&T, or T-Mobile, you will need to make sure your phone is unlocked first. If it's not, call your carrier and get an unlock code. That sometimes takes a couple of days (they don't want you to go!). Then you just enter the code on your phone to unlock it and go to Sprint's site to finish the process. Your next goal is to make sure your phone is compatible with Sprint's network. If it's any modern smartphone, chances are good that it is. But you'll want to find your phone's IMEI or MEID and enter it on the website.

After all that, all you have to do is sign up for one of Sprint's Unlimited plans. These plans start at $35 a month. Depending on how much you're paying now, you could potentially save money there as well. The plans include unlimited data, talk, and text. You'll get extra features like the ability to stream HD videos or use your phone as a mobile hotspot. You can even get bonuses like a free Hulu subscription or even subscriptions to Tidal or Amazon Prime depending on the plan you choose.

The $300 prepaid Mastercard will be shipped 90 days after you sign up.
