  1. Apple Watch Series 3 and Series 4 have a water resistance rating of 50 meters under ISO standard 22810:2010. This means that they may be used for shallow-water activities like swimming in a pool or ocean. However, they should not be used for scuba diving, waterskiing, or other activities involving high-velocity water or submersion below shallow depth.

  2. Wireless service plan required for cellular service. Apple Watch and iPhone service provider must be the same. Not available with all service providers.
