Giffgaff保活需要每180天余额变动一次,最方便经济的方式就是发条短信。步骤如下:
向任意国内外手机发短信,需要带上国家编码,如+44 797 300 0186,发送格式为00447973000186,内容随便写。
发送成功后,GIffgaff会向你发送一条短信告诉你余额变化,显示
Hi, that text was charged from your giffgaff credit balance. Your credit balance is now £14.09.
Stop notifications: giff.ly/stopbn
收到这条短信就说明扣费成功,有效期又可以+180天。
