Typically, cellular smartwatches target postpaid customers of Verizon, T-Mobile, or AT&T. But can you use a cellular smartwatch with your prepaid plan? The answer isn’t simply yes or no.While more than a dozen carriers technically support cellular watches, compatibility varies greatly by provider. Although Samsung, Apple, and Google dominate the cellular watch market, smartwatch compatibility often depends on specific brands and even models. Some prepaid carriers only support Apple Watch, while others exclusively cater to certain Google Pixel Watch or Samsung Galaxy Watch models.
