ONLY the Carrier the Phone is locked to can unlock it...
You need to Contact the Carrier and ask if they Offer this Service and if you qualify.
From what you have written... it looks like you may not be eligible.

There are several carriers in Thailand. Your friend should contact one of them and ask.

The process is contact your network supplier .
Ask IF they offer unlocking.
IF yes request the unlock and pay any fees requested.
Your network supplier then contacts Apple to request the White listing (Unlocking) of your phone on the iTunes servers.
Apple do this -It takes anything from 3 days to several weeks to complete.
On completion Apple confirms this back to your Network supplier (NOT YOU)
Your network supplier contacts you via email or SMS inviting you to connect your iPhone with your computer via the supplied USB cable and launch iTunes and follow on screen prompts through to the "Congratulations your iPhone is now unlocked" screen.
All these steps need to be carried out with the ORIGINAL SIM and by REGISTERED account holder used when setting up the phone.
Once the Congats...... screen has been reached you can swap out the REGISTERED SIM and replace with a compatable SIM on another network.
All above steps must be completed whilst directly connected to the registered network and can not be done when roaming -The mobile operator WILL check this using identifiers and mast triangulation.
Only the original SIM and Account holder can initiate an unlock- If you bought the phone used/second hand you CAN NOT UNLOCK through official routes
Once unlocked use of a Mobile Virtual Network SIM may result in difficulties sending SMS messages.
You may have to go into Setting /Network/Cellular/Cellular Data Network and enter the correct settings manually.

Firstly, you are not addressing Apple directly here - this is a public user to user forum, so don't post personal info on a public forum.
Secondly, the phone that you have is a Verizon phone which is actually a CDMA phone. If the phone has been used by the previous owner, then you should not need to activate it again, because it has been used on the CDMA network in the US by the previous owner. Both iPhone 4s's and 5's on the Verizon network have a sim card slot that is already unlocked and that you can use as the GSM portion of the phone, so all you actually need to do is purchase a sim card of your choice and insert it and you will be able to use the phone.
Note that this is a CDMA phone and Verizon and Sprint in the US are the providers of these services and CDMA networks do not exist in other countries except the US, that is it, but you can use the sim card try - just buy a sim card and insert it and away you go.
However, in the long run, you should consider buying a new phone that is not a CDMA phone that is compatible with the GSM networks of your country.

This is NOT correct. The only Verizon iPhone that is sold as unlocked is the iPhone 5. The iPhone 4S is sold locked and can only be unlocked by a current Verizon customer in good standing for at least 60 days.

Thank you very much for the information. However, the phone is already in Thailand. Keith Doherty3 said only the original SIM and Account holder can initiate an unlock. How about if I will be able to login into the previous owner account? We got the original SIM. I can ask the acccount information from the previous owner because the previous owner is a sister of my friend's girl friend. My friend is the one holding the phone right now.

The previous owner will need to contact Verizon and request the unlock. I think that they may refuse to unlock it as it is no longer active on the account.

If you can't get the phone unlocked, then you have no option but to sell it and buy a new phone that will work in Thailand.
