Having Problem With Internet

[SSRRWW]

For Some Reason I Cant Log On To The Internet. It Says My User Name Or Password Is Wrong. My Username Is My 10 Digit Phone Number With Mycricket.com And The Password Is Cricket. When I Put All That In And Hit Finish And Try To Get On The Internet It Wont. I Havent Had Any Problems Until The Other Day. I Have Done A Hard Reset And Still The Same Problem. I Did Check After I Put In The User Name And Password And After I Hit Finish I Went Back Like I Was Gonna Edit And The Password Is Longer Than What I Put In.... Im Totally Confused!!
