Hi boytroy88. My name is TracFone Jude and I will be addressing your question. You will need to activate the SIM card with 30 day prepaid 1 GB plan within a year from the date of purchase. For Unlimited Talk & Text Smartphone plans, any unused data after your service end date will carryover to the next cycle as long as active service is maintained and in use with any Unlimited Talk & Text Smartphone plan. For Basic/Classic service plans, any unused minutes, texts and web/data will not expire as long as any TracFone service plan is active and in use within any six month period. Please be advised to redeem your service on or before your service end date since the SIM card will be deactivated even if you still have data balance. You have an option to purchase your preferred service plan on or before your service end date. You can check this link
