T-Mobile and Verizon customers experience faster media download speeds on the iPhone 16. T-Mobile users noted a median download speed of 317.64 Mbps, while Verizon users reported a median download speed of 172.12 Mbps.
The disparity in speed is significant as T-Mobile boasts the only nationwide 5G SA network with advanced features like carrier aggregation. With the continuous enhancement of spectrum combining technology by T-Mobile, iPhone 16 users can anticipate improved performance over time. T-Mobile currently combines 217 MHz of spectrum, while AT&T and Verizon utilize two-carrier aggregation with 120 MHz and 170 MHz, respectively.
X85 modems support 6-carrier aggregation for downloads and can operate with more spectrum. Considering Qualcomm's modems' compatibility with advanced networks, upcoming iPhone 17 models, except the iPhone 17 Air, may feature the Snapdragon X80 5G modem seen in the Samsung Galaxy S25.
