Problems with iPhone visibility on computer

Sometimes a computer can't detect an iPhone's hotspot, which can be caused by software glitches or privacy settings. One common cause is the "Maximum Compatibility" feature, which changes the Wi-Fi frequency band. By default, the iPhone uses the 5 GHz band for high speeds, but older adapters in computers may not support it.

To resolve this issue, go to Personal Hotspot settings on your iPhone and turn on the switch.

Using your smartphone as a router puts a strain on the battery and can lead to the device overheating, which in turn affects processor performance and data transfer speed. To minimize risks, it is recommended to remove the case during long internet sharing sessions, ensuring better heat dissipation.

Telecom operators often limit speeds after a certain high-speed data limit is reached in modem mode. Even with unlimited plans, there may be a limitation, for example, 10 or 20 GB per month, after which the speed drops to 64 or 128 kbps. Monitor your data usage in the section Cellular communications.

How many devices can be connected to an iPhone hotspot at the same time?

Apple officially supports up to five devices for the iPhone SE and older models, and up to 10 devices for the iPhone 6 and newer. Exceeding this limit may result in network instability and excessive device heating.
