Watch-phone: TOP 10 best smartwatches with a SIM card

The functionality of smart watches is enormous - they show the time, wake users up in the morning, measure heart rate, estimate the amount of oxygen in the blood, control stress levels, and help make sports training more effective and safe. Some users want call functionality in them. Voice calls in the watch are implemented in two ways:

• Using a SIM card - it is installed directly into the watch, turning it into a mobile phone. Constantly rearranging SIM cards is inconvenient, so backup numbers are installed here. Also, such watches are used by children;
• Using a smartphone - here the watch acts as a headset or speakerphone. The call itself is initiated by the smartphone.

The second method is convenient because it does not require rearranging the SIM card.

Our review included three smartwatch models with their own SIM cards and seven models that work as a headset connected via Bluetooth. Brands – Samsung, Apple, LEMFO, Huawei, Honor, iCONIX, GEOZON and Amazfit.

Smart watch phone - what is the difference with a regular smart watch?

Regular smartwatches can show the time, display notifications, and launch some applications, such as those for running. That is, it is a companion device. Without a Bluetooth-connected smartphone, they are not very useful.

A smartwatch with a SIM card is a more autonomous device. They don't need a smartphone. They will also retain the functionality of a companion device, but at the same time they are able to receive calls, make calls, receive SMS, and so on.
