Identification of mobile carrier users (3G/4G) is a complex feature.
We use both our own and third-party databases of IP addresses to identify carriers, and it requires constant maintenance. Depending on the tool you are using, and how that tool is identifying users (IP addresses, ISP name…) you may see differences. For this reason we can not guarantee the accuracy of this identification.
If you require 100% accuracy, we suggest instead that you use your own IP address ranges, with the IP Ranges targeting option found in step 6 “Advanced settings” when creating/editing your campaign.
