Hi,

I purchased a pre-paid 12call sim at Tukcom, Pattaya, a few days ago. At first it would not make outgoing calls, but after a visit to a Tukcom guy who did something with the software, outgoing calls did work. However, a few hours ago I found that I can no longer make outgoing calls, I get a call failed message. The same problem as I had at the start.

I can go back to Tukcom tomorrow and try again, but what is going on? Does anyone know if there is some basic incompatibility between the iphone and 12call ?

Thanks for any help.

Is your iphone unlocked and jailbroke.

If so you need to have cydia running and then add the yellowsn0w to be able to unlock the phone to use 12call.

Do not get someone to hack it for you, i did this and learnt the hard way. Your phone then gets locked to the computer that was used as it registers there Itunes account.

if you need some information on this look on
