 新版雙芯卡

1. 使用八個門號，網內互打超便宜，免除漫遊費

2. 當您擁有2張SIM卡時，不必在同時攜帶兩隻手機，笨重又麻煩

3. 換門號時不必再大費周章，還要拆下背蓋或電池取下原SIM卡後又再換另一張卡，煩人又費事

4. 出國或須要用另一門號時，隨時都可很輕鬆的依需要切換到您想用的門號，快又方便，非常適合往來兩岸三地商務人士使用

5. 不會像市售普通雙卡背蓋厚度增加很多，難看又易當機；普通雙卡軟排產品也已印證問題多多

6. 本產品超薄又穩定，即使和別人用的厚厚雙卡背蓋比較，您的手機也一定比他更炫更美觀

7. 擴充新增手動輸入六組門號功能，一支手機等於可當8支手機使用

8. IP電話功能 (使用者可自行設定節費碼，並選擇最優惠之通話費率)
