The Tracfone $10 Data Card is the easiest way to purchase extra data mid-cycle, adding 3GB of High-Speed Data to your existing balance. This card is strictly for Smartphone Plans Only and does not add service days to your account. This is a must-have accessory for users who occasionally run low on data, as the added data rolls over and never expires with active service. General Legal Disclaimers & Terms of Service: Service Compatibility: Basic Minute/Day cards are strictly for Basic/Feature Phones. Smartphone Unlimited plans are for Smartphones Only. Data Roll Over: Unused data, minutes, and texts will roll over and accumulate only with active service (renewal before the service end date). Unlimited Data: Unlimited data plans may experience reduced speeds (down to 2G) after a high-speed allotment is used (e.g., 60GB for the $50 plan). Hotspot: Hotspot capability is only included on the $50 Unlimited Plan. Final Sale: Service plans are non-refundable once purchased or activated.
