Troubleshoot if you are getting Error 651 with your Sprint 3G/4G USB Modem U300 connection card
Sprint Search is designed to answer questions that are worded in plain,
conventional English, just as you would ask them to another person.
For example:
Type "What BlackBerry phones do you sell?" instead of "cell phone"
Type "How do I change my password?" instead of "password"
Type "What plans do you offer for families?" instead of "plans"
Try checking your spelling and grammar to help get the most accurate results.
Correct capitalization is not required, but can sometimes help to locate names and acronyms.
