Activating an unlocked iPhone with Straight Talk SIM card is quite easy because either AT&T or TMobile can be used. The easiest models to activate are the iPhone 3g, iPhone 3gs, iPhone 4 and the iPhone 4s. That is not all, Network Settings screen full access is also possible and it also lets to enter the new MMS settings and Straight Talk APN settings without the need to jump through different processes like usually done on an AT&T locked iPhone.
If you want to activate your iPhone with the Straight Talk SIM card program, just perform the following steps:
The first thing that you should do is to go to the webpage for Straight Talk. Before you can start the process though, you must first access your SIM card’s serial number. Look at the red card that comes with your SIM kit. That card has the serial number of your SIM card. If you have no access to the serial number red card, you can also find the serial number on your SIM card, which is the underlined number that is printed on the SIM card’s front part. The activation process should take about 10 minutes minimum and one hour maximum.
The next step is to use the SIM (newly activated) into your phone. For the iPhone 3g and 3gs models, you can see the SIM card tray at the top part of the unit.
For iPhone 4 and 4s models, it can be found on the right side of the unit. You may need to use a paperclip in order to open the tray. There is a small hole in the tray where you should stick the paperclip.
Once the SIM card has been installed properly, it is about time to start synching your iPhone to iTunes. You need to do this before you can start using your phone. If iTunes is not yet installed on your phone, you need to do that first. The process is easy as all you need to do is to follow simple installation steps. After the synching process, there should be HOME 3g displayed on your phone as well as the signal bars. If there isn’t any AT&T words visible, it’s alright, that is quite normal. By that time you should be able to use your iPhone for making and receiving calls as well as sending and receiving text messages. To be on the safe side, you should try to call someone, to ensure that your phone is active.
Once you are sure that your iPhone works like a regular phone, you should start data activation. Remember that you need Cellular Data Network screen access in order for this process to go smoothly and easily. This should be available with all unlocked iPhones, so there shouldn’t be any problems.
The next thing you need to do is to go to Setting. Then go to General. Then choose Network. The option for Cellular Data network should be there.
Go for the Cellular Data Network and then you have to enter the Straight Talk Settings based on the preferences of the network carriers.

If everything seems to be working well and all testing attempt have gone well, then you have successfully activated your iPhone with Straight Talk SIM Card Program.
