Boom! Mobile has ceased offering their service on Yellow, AKA Sprint. All Boom! Yellow customers will be transitioned to Ting CDMA and will receive a special offer ($20 unlimited talk/text/data) via email to either continue their service or port away to another carrier. This offer is ONLY available to Boom! Yellow customers.
"$20 unlimited talk/text/data" seems like a good deal.
