I bought an Apple Iphone 4S unlock.
I put my Straight Talk sim card, I am able to talk and text but my data is not working.
The option Cellular Data Network doesn't appear.
I also tried the unlockit.co.nz website but it's not working.
Try resetting your network settings by going to Settings>General>Reset>Reset network settings
If that doenst work, try restoring your phone and if that doesnt work. Go back to straightalk and have them look at the sim card.
Retrieving data ...
