We use WhatsApp only when you start a conversation, provide your number for support, or give clear consent to receive a relevant service message. Typical messages concern product compatibility, order status, delivery, warranty, troubleshooting, and customer-requested setup assistance. We do not buy contact lists or send unrelated unsolicited messages.
You may stop WhatsApp messages at any time by replying STOP, BERHENTI, or clearly asking us not to contact you. We will record the request and stop non-essential WhatsApp messages. You may still contact us by email at zhaihai@haichangxing.com.
We may explain device setup, SIM compatibility, or the official steps required by a mobile network operator. Do not send passwords, OTP codes, payment-card data, full national identity numbers, passport numbers, or unredacted identity documents in ordinary WhatsApp chat.
For YES SIM activation, use the official MyYes app: select New User, choose Activate SIM, scan the SIM or barcode, then complete identity verification in the app's eKYC flow. For operator assistance, use the official YES support page or email yescare@yes.my.
WhatsApp is provided by Meta and is subject to Meta's own terms and privacy practices. Our handling of chat content and contact details is governed by our Privacy Policy. We retain only what is reasonably necessary for support, security, legal, and dispute-handling purposes.
