To enjoy every feature on your Apple Watch, you need to turn on Wi-Fi and Bluetooth on your paired iPhone. Open Control Center on your iPhone, then make sure Wi-Fi and Bluetooth are on.
Your Apple Watch uses Wi-Fi and Bluetooth to communicate with your paired iPhone. If you have cellular, your watch can also stay connected through a cellular network. Your watch switches between these intelligently to choose the most power-efficient connection. Here's how:
- Your Apple Watch uses Bluetooth when your iPhone is near, which conserves power.
- If Bluetooth isn’t available, your Apple Watch will try to use Wi-Fi. For example, if compatible Wi-Fi is available and your iPhone isn't in Bluetooth range, your Apple Watch uses Wi-Fi.
- If Bluetooth and Wi-Fi aren't available, and you set up a cellular plan, cellular models of Apple Watch can connect to cellular networks.
This is a program for finding devices on iOS nearby and sending documents via. Your iPhone uses the Bluetooth 4.0 protocol. Bluetooth is a short-range (up to 300 feet) wireless protocol used to attach, or pair, devices to your iPhone. Unlike Wi-Fi, which broadcasts its availability continuously, Bluetooth has to be turned on to make your iPhone or other device discoverable so.

Connect to a compatible Wi-Fi network
Your Apple Watch can connect to a Wi-Fi network:
- If your iPhone, while connected to your watch with Bluetooth, has connected to the network before.
- If the Wi-Fi network is 802.11b/g/n 2.4GHz.
For example, your Apple Watch won't connect to 5GHz Wi-Fi or public networks that require logins, subscriptions, or profiles. When your Apple Watch connects to a compatible Wi-Fi network instead of your iPhone connection, the Wi-Fi icon appears in Control Center.
