It is 2AM, You Cannot Connect to Sprint EVDO, Change your HA

If you're having a connection issue during a time of day when you can't get in touch with 3Gstore.com or Sprint, all hope may not be lost. Some of these connection issues can be fixed by changing your HA (Home Address).

We have a pretty extensive thread on EVDOForums.com discussing how to do this:

Sprint ##DATA tuning (changing Home Agent)

The process is relatively easy, the only problem we foresee customers having is not knowing their MSL/Activation Code. If you're a 3GStore.com EVDO Card customer, here are instructions on how to find that number:

1. Log in to 3GStore.com with your email address. If it tells you that your password is incorrect or that an account already exists with that email address, just click on "Forgot Password" and an email will be sent with a new password.

2. Once you are logged in, you will have access to the information you need. Click on "My Account" at the top, and find the order for your EVDO card. Click on "View", and you will see all comments made on your order.

3. One of the comments should have a format like this (the numbers will be different, of course):

PTN 3256661234 (this is your phone number of your aircard)

ESN/MEID 09104612345
MSID 000004820535723 (drop the leading zeros for your MSID)
SID/BID 23722
One time Subsidy Lock 923423
Alternative Lock 420473

The 6-digit "Alternative Lock" number listed is the MSL/Activation Code required to change your HA. And that's it! That's everything you need to know to change your HA and hopefully fix any connection issues you may have been having.
