Apple is set to unveil the latest addition to its iPhone SE line, the fourth-generation model, which will come with several new features including an OLED display and Face ID. One of the major changes with this new model is the introduction of Apple's first in-house 5G modem, manufactured by TSMC.

However, reports from South Korea suggest that Apple's modem for the iPhone SE 4 will not support mmWave 5G, potentially resulting in slower upload and download speeds compared to flagship models from competitors like Qualcomm. Despite this limitation, Apple is expected to incorporate features like Dual Sim Dual Standby and enhanced integration with its main processors for improved efficiency.

As Apple continues to expand its in-house chip development, the iPhone SE 4 will serve as a testing ground for the company's modem technology, paving the way for future innovations in connectivity and performance.
