I'm trying to do call forward and the instruction says, I need to go to menu then options and I should see "call forward". However, I don't see that on my t-mobile Pearl. Does this mean I can't do call forward? :(

Thank you...

Just figured it out.

Use the *21*Number# then press the send (green button). Check the phone options to ensure that the forwarded number is in there. Then you can switch back to the voicemail number at any time. I've also rebooted my phone and the number that I to forward stayed in the menu.

Hope this works for you.

Thank you very much. I press the code you have and now my phone got forwarded. Now, how can I cancel that? Thank you.

Just either use #21# send or go to the call forwarding menu and select the voicemail phone number.

Thank you again. You save my life!! I'm at the airport to go oversea right now and this call forward solution help me greatly. Thank you.

I wonder why the Pearl needs different codes than most other cells ?

This is different and to block and unblock for CID is too.

First 500 mins or so are free in call forwarding under TMO.
