If your SMS campaigns are seeing high undeliverability rates, the problem might not be your content—it could be your carrier.
Cell phone users change carriers because they either want to save money or are not satisfied with their current service.
When a phone number is assigned to a new carrier, it is also assigned a new local routing number to identify the new carrier. This process of transferring an existing number to another carrier is called number porting.
If you are sending messages to a specific carrier and if a number is ported, the message will be sent to a wrong carrier. This is why it is important to verify a number’s carrier designations prior to sending text messages.
