The Sprint Modem Activation Corrective Action covers an unsuccessful auto activation process, auto activation failure to start
process, and manual activation process to determine if the modem failed or there is a problem with the data connection.
Unsuccessful Auto Activation
This is what you will see if Auto Activation fails.
1. Verify just what happened by entering AT+WDSW? If the modem responds with +WDSW: 12,0 HFA did not complete.
2. Confirm that the modem is registered to the Sprint Home Network, enter AT+CREG? The modem should respond with 0,1.
3. Set preferred roaming status by enterring AT+WRMP=1
4. Reset the modem by enterring AT+CFUN=1 and let the modem auto activate again. If the auto activation is successful, the
5. If the modem fails again, perform the manual activation process to determine if the modem is defective, the data connection
Auto Activation Failure to Start
Failure of auto activation to start could be due to account not active, a weak signal, or Sprint not seeing the activation attempt.
If you still do not see an indication of auto activation, wait for 2 minutes and try the following sequence to try to start the
activation.
1. Start the process by enterring AT+CSQ?
2. Replace the antenna. If you now have a strong signal, enter At+WRMP=2 (allow roaming).
3. Wait 10 seconds, if auto activation starts, the modem will automatically restart the activation sequence. If so you are done
4. If the auto activation still has not started, perform the manual activation process to determine if the modem is defective.

If the modem responds with something other than 0,1, then you are not on the home network and the unit will not activate.
modem will respond with +WDSI: 22,2 (HFA succeeds). You should now be able to make a data call and verify your account.
is failing due to the Sprint account not being active, Sprint is not seeing the activation attempt, or preferred roaming is not
established.
issues are either a bad antenna or you need to set preferred roaming.

Appendix F – Sprint Activation Failure
Verify with your carrier that the account is activated, once the account is active, the modem will automatically restart
the activation sequence.
For a weak signal, move the modem to where you receive a strong signal, once the modem receives a strong signal,
the modem will automatically restart the activation sequence.
To determine why the auto activation was unsuccessful, first determine whether the modem is registered on the Sprint
Home Network or if roaming is preventing activation.
Next, if the modem fails to auto start the activation, determine if the modem has a a weak signal, defective antenna,
the Sprint account is not active, does Sprint see the activation attempt, or preferred roaming needs to be set.
Finally, initiate manual activation to determine if the modem is defective or if just the data connection is failing.
