For current Verizon customers, Sprint continues to offer one year of its Unlimited Plan for free when you switch to Sprint by purchasing a SIM card for your current Verizon phone. (The SIM card costs $2.99 plus $10 for overnight shipping.) Excluding the cost of the SIM card, that's tied with last week's mention as a savings of $720. You'll bag unlimited talk, text, and data, while getting to keep your phone and phone number. Some exclusions apply.

Note: This offer is only available for current Verizon customers and requires that you sign up for AutoPay. You'll receive this discount as a monthly bill credit, which will be applied within two invoices. (Other monthly charges may apply.) After your free year is up, you'll be charged $60/month for this service.
