The iPhone 7 and 7 Plus use different LTE modems, sourced from Intel and Qualcomm. The Intel modem only supports GSM and is limited to the AT&T and T-Mobile networks in the U.S., while the Qualcomm modem supports GSM/CDMA and is available for Verizon and Sprint. According to iPhone 7 Plus testing done by Cellular Insights, the Intel iPhone models perform worse than the Qualcomm models when in areas with poor signal. When signal strength is good, there are no performance problems, and real world experience may vary from user to user.
Apple may also be throttling the LTE performance of the Verizon iPhone 7 with a Qualcomm modem to keep it on par with the AT&T iPhone 7 with an Intel modem. Based on testing, the Verizon iPhone 7 should significantly outperform the AT&T iPhone 7, but instead, the two devices perform similarly with the Verizon iPhone 7 displaying only a slight edge.
When compared to a Samsung Galaxy S7 that also has a Qualcomm chip, the Verizon iPhone 7 could not compete, suggesting Apple has limited its performance to ensure feature parity between iPhone models on different networks.
