Many plans state "Unlimited Carryover," which means unused minutes, texts, and data roll over instead of expiring as long as the service remains active. Smartphone unlimited plans similarly note that unused data will not expire while the service is active and in use.
The 30‑day smartphone plans in this selection are described as unlimited talk and text (listed as "Unlimited Minutes") rather than fixed‑minute refill cards.
The plans note 5G coverage and list compatibility with 4G LTE and 5G smartphones. They specify that 5G access requires a 5G‑capable device and being in a 5G coverage area.
The available details list the calling area for these cards as domestic.
The smartphone unlimited talk plans shown are 30‑day plans per cycle.
