A new study finds that when you call your land line from your mobile device, you are actually getting a message from your carrier — even if the message comes from a different phone number.
In a paper published by the Association for Communications Research, researchers found that even when a text message is coming from a mobile number, it is still the carrier that is the source of the text message.
In fact, when a message is sent from an iPhone, the message is from a landline phone number, while a text on a land line message is the carrier of the message.
This means the text messages you send from your phone to your land lines are still being sent from the carrier who originally sent the message to you.
The researchers say this makes it difficult to accurately track how many people are receiving text messages on land lines, which is why they created a new test to assess whether text messages are being sent correctly.
The test involves sending a text to a land number, which the test phone uses to identify the text from the land line, and sending a second text message, which identifies the text sent from a phone number in the mobile network.
After the first text is sent, the test test phone can determine the text received from the other land line.
When a test phone identifies the two text messages sent from land lines and a second test phone receives both texts, it can determine which phone number is sending the message and whether the text is being sent to the right phone.
The study found that when a mobile phone receives a text, the mobile carrier will use its own data to identify which text is coming in, and it will also use the carrier’s own network traffic for its own identification.
This is the same method used by other mobile carriers to identify text messages.
The results were statistically significant when the two texts were sent from different land line numbers and the tests included multiple carriers.
The paper says this information allows the test phones to “fingerprint” the text, which helps the test system identify which land line is sending a message to which phone.
“This provides a measure of accuracy for text messaging and the reliability of carrier-based messages, particularly when a large number of mobile carriers are involved,” said co-author and University of Texas at Austin professor Mark Luscombe.
“We know that text messages that have been sent from cell phones can often contain incorrect or misleading information, such as location information, which can result in misleading messages appearing in users’ text messages,” Lusborough said.
The research team also discovered that when the test device receives a second message, the land phone will continue to send the text as it normally would.
The findings, Luscastle said, “provide a valuable opportunity for mobile carriers and data service providers to better identify, and mitigate, the effects of incorrect carrier messages in text messaging.”
The research was funded by the National Science Foundation.
