Next in Send and Receive on the iPhone > Settings > Messages > Send and Receive you can add the Apple ID. Linking Apple ID and iPhone Number for iMessages
The Mac version cannot be set to send SMS from the Mac version - it requires the steps that follow. This allows that device to send iMessages to any ID that is registered be it Apple ID or iPhone Number. Next you can add/register an Apple ID on your Mac. Whilst the other end might be registered it might not be able to Login due to the wrong type of Carrier Service, lack of WiFi service or simply being without power.Īll of these may generate an Error messages that reads 'Not Registered with iMessages'. So already you have lost some control as the app decides if the iPhone at the other end can receive iMessages. Then you can elect to turn On SMS when the iPhone will send SMS to non iPhones or to iPhone that are not registered with iMessages (as a service) when the app thinks it cannot send an iMessage. You can turn the app On and it will, after verifying the iPhone Number (Register) be able to send iMessages to iPhone Numbers (that are also registered) or to Apple IDs that are registered.Īpple IDs can be used on Macs, iPads and some iPod Touch devices.
I have not spotted if you have said the other person is using an iPhone. I think you have all the info in the previous Posts but may be a run though might help.
