If a phone is on the blacklist, do SMS messages arrive in WhatsApp - briefly?
If a phone is on the blacklist, SMS messages will not arrive in WhatsApp because the device's IMEI number is flagged, preventing it from receiving standard cellular network services including SMS.
If a phone is on the blacklist, do SMS messages arrive in WhatsApp - in detail?
When a phone is added to a carrier's blacklist, it typically becomes restricted from certain services due to reasons such as unpaid bills or being reported as lost or stolen. In the context of SMS messages and their delivery to WhatsApp, several factors come into play.
Firstly, it's important to distinguish between standard SMS messages and those sent through WhatsApp. Standard SMS messages are delivered via the carrier's network, while WhatsApp uses internet connectivity to send and receive messages. If a phone is on the blacklist, carriers may restrict or block standard SMS services to that device. However, this restriction does not necessarily extend to WhatsApp messages, as they do not rely on the carrier's SMS network.
WhatsApp messages are sent over the internet using data connectivity. As long as the blacklisted phone has access to Wi-Fi or mobile data, it can send and receive WhatsApp messages without interference from the carrier's restrictions. This means that even if a phone is on the blacklist, WhatsApp messages should still arrive, provided there is an active internet connection.
It's worth noting that while WhatsApp messages themselves are unaffected by the blacklist status, certain features of the app might be impacted. For example, voice and video calls could be disrupted if the carrier restricts VoIP services on the blacklisted phone. Additionally, receiving verification codes via SMS for account setup or login may become problematic since these codes are often sent as standard SMS messages.
In summary, if a phone is on the blacklist, WhatsApp messages should still arrive as long as the device has internet access. However, other features and functionalities of both the carrier's network and the app itself might be affected by the blacklist status.
