Must have SG Pre/Post-paid SIM to work
I tried using my US number after selecting NO when it asked if it had a SG SIM, and it froze after clicking next after entering my Birthday and number. I went to the store and got a cheap $15 prepaid sim and then selected yes on that screen then it let me through, then i now can use the wifi. this review was written on WiFi@SGx. app interface very slow and kind of crappy tho.
