Apple Watch Series 4

Apple Watch Series 3 and Series 4 have a water resistance rating of 50 metres 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.
Wireless service plan is required for cellular service. Apple Watch and iPhone service provider must be the same. Not all service providers support enterprise accounts; check with your employer and service provider. Roaming is not available outside your carrier’s network coverage area. Contact your service provider for more details. Check www.apple.com/in/watch/cellular for participating wireless carriers and eligibility.
