Jailbreaking your iPhone 4s won't allow you use other network sim card. You need to Unlock the carrier lock of the iPhone 4S to use it with other network sim card and the process to unlock carrier lock is called Unlocking.

Here is the difference between unlocking and Jailbreaking:

Jailbreaking is the process of removing limitations/restrictions so that 3rd party applications can be installed. Unlocking a phone is a procedure to remove any SIM/Network restrictions set on the phone by either the manufacturer of the phone or by the mobile phone's service provider.

To unlock your iPhone 4S you can get Remote Unlock Service from MobileUnlockSolutions.com . There you have to give your Country and current Network name along with your IMEI number to get Remote Unlock Service.

Hi,
