zakumark 發表於 2018-1-12 18:57  KnowRoaming is now permitting the use of WhatsApp (this includes messages, voice, pictures, and calls) without incurring any associated data charges. WhatsApp usage will not deduct from your balance and will not appear in your Usage Section of the KnowRoaming App. Even if you run out of credit on your KnowRoaming account, you will still be able to access and use WhatsApp.If you see data charges on your account, it means you have other applications on your device accessing data, since WhatsApp will not appear in your usage history.
It looks like they may record whatsapp usage as well. |
