Switch to Sprint and get up to five lines for just $100 a month through mid-2020

Switching cell phone providers sounds like a hassle, but it can save you a ton of money in the long run. Sprint makes it easy to switch, and with its current Unlimited Basic deal, the savings are hard to resist for those with multiple lines. For a limited time when you switch to Sprint, you can select its Unlimited Basic plan and get your 3rd, 4th, and 5th lines absolutely free through June 30, 2020. That means you'll pay just $100 monthly for up to five lines through the next year, after which time you'll be charged $20 per additional line.

The Unlimited Basic plan is also perfect if you plan on leasing a device or using your devices as a mobile hotspot. It even bundles in Hulu which could save you some cash if you're already a subscriber or planning on cutting your cable company out of your life soon.

On the other hand, there's the Unlimited Kickstart plan for only $25 monthly. That includes unlimited talk, text, and data for your device as well, though the deal requires that you purchase a new line of service. Additional lines can be added at $25 per month each. If you already own an unlocked phone you'd like to keep using, Sprint allows you to use it with your new service plan. However, if you do buy a new phone while signing up for today's deal, Sprint will throw in a $100 prepaid MasterCard. That's like getting four months of service paid in full.

With both the Unlimited Basic and Unlimited Kickstart plans, there are some limits (you heard that right) you'll encounter, such as unlimited video streams that are capped at 480p (standard definition), music streams up to 500 Kbps, and gaming up to 2 Mbps.
