Will my phone work in Japan?
My phone is Balckberry Curve 8520 with the ff specification:
BlackBerry Curve 8520:

* Quad-Band: 850 / 900 / 1800 / 1900MHz GSM/GPRS networks
* Quad-Band: 850 / 900 / 1800 / 1900MHz EDGE networks
Given this, If i insert a Japanese sim card, Will I be able to text and call then using my phone?
