One of these methods is deep packet inspection (DPI). This process involves examining the content of network packets as they travel through the carrier's network.

Additionally, some iPhone models may also inadvertently reveal personal hotspot usage to carriers. This can happen due to specific data transmission patterns or other factors.

DPI works by looking "inside" each packet and analyzing its data. This allows carriers to identify patterns or signatures associated with personal hotspot usage.

Another technique used is TCP/IP stack fingerprinting. This method involves analyzing the unique characteristics of the TCP/IP protocol stack used by a device when connecting to the network.
