Check your server settings.
Your Incoming server should be pop.xxx.cox.net
Your outgoing server should be smtp.xxx.cox.net.

The "xxx" is dependent upon the Cox region in which your email account is based.

For example, I am in VA so my incoming server is pop.east.cox.net. Check your Cox account for the exact settings

i want 8digits network key control my phone its not working oll sim

Samsung... • Answered on Apr 15, 2014

Hello Friend,
Here is the procedure:
  1. First you’ll need to get your Network Control Key. The Network Control Key is a 8 digits unlock code. There are two paths to get your NCK. You can either call AT&T or ask for it. You may have to ask them to put you through to their tech department. If you’ve never signed up for AT&T’s Service they may not give the code because your not a customer. The other way to get the code is to contact a cell phone unlocking service. They usually charge around $20 to get this code for you.
  2. Once you get the Network Control Key power off the phone.
  3. Remove the SIM card.
  4. Power on the phone back on.
  5. Enter #7465625*638*
  6. Enter Network Control Key.
  7. Press “OK” Soft key, not the Send or OK hard key.
  8. Power off the phone.
  9. Reinsert the new SIM card.
Best Regards,
