thats the same plan i have, well i have one of these & also a family plan under EPRP.. closest to SERO i could find.
haters will tell you that you arent a "premier" customer & dont get the yearly upgrades & discount on accessories. just fyi.
however i think $10 a month cheaper & cheaper most other things is well worth it.
good info even tho i already knew it all
the original sero link gets you there too,
http://www.sprint.com/sero & credentials are the same
you can also get this plan by calling sprint employee care @ 1-888-876-8381
& no you dont have to be an employee or have any ties with sprint, its basically for people are "in the know"
