The caller with the number +64272640775 made a call to a recipient in Brisbane, Australia, at 1610 hrs QLD time. The recipient called back, but the service was temporarily disconnected, indicating that the caller might have been using a prepaid or voip service that was suspended or out of credit. This suggests that the caller's service was not a standard post-paid mobile or landline connection. The fact that the recipient received a message about the service being disconnected implies that the caller's number was likely a valid number, but the account or service associated with it was not active or was restricted.
