"...Sprint's new Unlimited 55+ plan — which was rumored back in April — is available today. Now, Sprint customers who are 55 or older can sign up for one line of unlimited service for $50 a month or two lines for $70.
Customers who meet the age qualifications will get the same perks as the regular Sprint unlimited plan (which usually costs $100 per month for two lines), including unlimited talk, text, and data, along with mobile hot spot (limited to 3G speeds) and international texting and data (limited to 2G speeds). You'll also be subject to Sprint's use-case specific speed caps, which limits video to 480p, music streaming to 500 kbps, and gaming streaming to 5 Mbps. If you're a Sprint customer who's over 55, it's pretty much a no-brainer. ..."
