Can I receive texts and calls on Apple Watch sport

Hi

All models of Apple Watch can be used for making and receiving phone calls and for sending and receiving texts:

• https://help.apple.com/watch/#/apd32b6c5658

Note that Apple Watch does not have built-in cellular capability, so the availability of those features depends on certain things:

The full range of features - including phone calls and messages - is available when Apple Watch and iPhone are connected via Bluetooth and the iPhone has cellular service.

Whenever your watch can't connect to the iPhone via Bluetooth, it will attempt, as a fallback, to connect to a known, compatible Wi-Fi network.

If it is unable to connect either via Bluetooth or Wi-Fi, Apple Watch again still offers some - although fewer - features, which do not include making or receiving phone calls.

Features that remain available in either case are detailed here:

How to use your Apple Watch without your iPhone nearby - Apple Support

For the best performance from your iPhone and Apple Watch, including the most power-efficient communication between them, Apple recommends keeping both Bluetooth and Wi-Fi permanently enabled on your iPhone.

In respect of the differences between models:

• Apple Watch (1st generation) models - which include Apple Watch Sport - have a single core processor.
• Newer models - in the Series 1 and Series 2 ranges - have a faster, dual-core processor.
• Series 2 models also have:
  • A higher level of water resistance.

    The watch can be worn, for example, when shallow water swimming and is also more resistant to water than other models during general daily use.

  • A brighter display (twice as bright as 1st generation and Series 1 models).
  • Built-in GPS.

    This can be used to track workout route maps for certain outdoor workouts when the paired iPhone is not also taken along and can also be used to help locate a lost watch (subject to it being connected to a trusted Wi-Fi network).

• Aluminium models have Ion-X glass (these watches are lighter in weight than stainless steel models of the same case size).
• Stainless steel watches have a sapphire crystal, which is more scratch resistant than Ion-X glass.

All Apple Watch models are able to run the latest software (watchOS) version.
