what is the difference between nationwide talk & text coverage and roaming coverage?

Nationwide Talk & Text Coverage allows you use your phone without roaming costs in all 50 states (including the top 125 cities nationwide) and Puerto Rico.

Roaming provides customers the ability to use their Cricket service throughout the US and Canada while outside the Nationwide Talk & Text Coverage area for an additional charge. Cricket Wireless customers can use their Flex Bucket or prepurchased roaming minutes to use Cricket service in roaming areas.

Cricket PAYGo customers must use their account balance to pay for roaming minutes. All customers should update their Preferred Roaming List (PRL) by dialing *228 before entering a Roaming coverage area.
