How do I activate a used straight talk phone I bought?

SOURCE: looking for serial number on straight talk cell

if you need serial number type *#06# and you will see the serial number of that phone (can be done to any)

SOURCE: I need a sim unlock code for a straight talk

You can get the unlock code through online..........give your IMEI number and get the unlock code for ur mobile.... i will suggest the website Unlock-Zone.com which is doing good service .....you can approach this website.
This site is nearly perfect and they were recommended highly in the cell phone forums. I used them to unlock my cell phone. contacted them and within 30 mins i had my unlock code and my phone was unlocked.
Hope this helps.

SOURCE: want to unlock/jailbreak straight talk samsung

Jailbreaking in IOS is rooting in Android. You root the Precedent (gain access to the root login) by using rtto at http://codegeekbbs.com/samsung.php Just follow the directions you'll find in the file. Just read the Readme.txt file.

Unlocking is making the phone run on other carriers' towers - and you can't do that with a CDMA phone without pretty much rebuilding the phone. (CDMA phones don't have SIM cards, only GSM phones do - the technology is different.)

This is controlled in your settings menu under 'Fixed Dial'. (or similar command). You will need to change this setting.

I do not have a copy of the user guide for your phone but for most phones these are the directions:

When you turn on fixed dialing, you
can call only numbers stored in the
fixed dial list.
Turn fixed dialing on or off:
- > Settings > Security > Fixed Dial
Use the fixed dial list:
- > Settings > Tools > Dialing Services
> Fixed Dial
