peoples儲值卡優惠一問？？

Sounds to me that this low-cost plan is limited to Peoples ( i.e. China Mobile ) own network users only. If you send SMS to those from PCCW, Smartone, etc, the charge is definitely different.

Nevertheless, I suggest you to contact initiative for clarification. For further inquiry, you may call its 24-hour customer service hotline 2945 8888 for details.

Hope I can help you.
