can i use roaming as soon as i activate my flex bucket account?

Once your Flex Bucket account is activated it may take up to 24 hours before you will have full use of your Flex Bucket funds. To guarantee quick access to Roaming service please make sure that you have updated your Preferred Roaming List on your Cricket phone, have Flex Bucket funds or subscribe to a rate plan that includes a monthly allotment of Roaming Minutes.
