you can also check the mcc and mc... whatever the other one is. mcc is ALWAYS 310 for cricket and the other code (which is usually 27 on alltel phones) needs to be 00.

you can check this in the nam programming (##000000send) or under the nam tab in workshop right under the MIN and next to the SID/NID pairs.

if you have access to CID make sure that the WAP0 code is on the acct or wap will not work. if you have your settings right you will at least see the $5 web subscription page.
