My sim card doesnt work in my sciphone i68+
I see that this had been a while. The reason that your Sim cad doesn't work could be various:
1. Make sure that your phone is quad band, if it's a tri band then make sure that ATT works in 1900mhz. If it works only in 850 and your i68+ is a tri band, (which is not suppose to) then it will never work. As far as I know all i68+ original are quad band, some fakes i68+ are sold as quad band but are actually tri-band.
2. If you ATT sim card is a 3g card, it won't work either. These phones are not yet equip to work with 3g.
I hope this clear up at least a little of your doubt with the Sciphone.
