If you Can’t Send or Receive Messages on iPhone, you can find below the steps to troubleshoot and fix the problem of iPhone Not Sending or Receiveing Messages.
Can’t Send or Receive Messages on iPhone
When you send Messages from iPhone to other Apple Device users, Apple makes use of its own iCloud Network to deliver the Message in the form of a Free iMessage (Blue bubbles).
However, if your Contact is using an Android device, iPhone sends the Message as a SMS Text Message using the Network of your Cellular Service provider.
This dual routing of Messages happens both while sending and receiving Messages on iPhone and this can sometimes lead to problems.
Messaging problems on iPhone can also be caused due to Network Connectivity issues, Accidentally blocked phone numbers and various other reasons.
