We’ll show you the four best smartwatches with SIM. In comparison, we clarify which technical differences there are in cell phone watches and which target group they are best suited for.

A smartwatch with SIM is the perfect choice for anyone looking for a practical smartphone alternative. Since the smart watches have their own, independent SIM card, they can also connect to the Internet without WLAN. What is even more important, however, is that you can also use them to make phone calls and send SMS.

When choosing, however, you should consider that there are cell phone watches with external SIM slots as well as with permanently integrated eSIM cards. The latter are therefore virtual and only have to be activated by a mobile operator, while a real SIM card has to be inserted into smartwatches with a slot.

Apple Watch Series 5

The Apple Watch Series 5 offers you everything you can expect from a first-class smartwatch. The mobile phone watch is equipped with an OLED display, which is guaranteed to be shock and scratch resistant thanks to the Sapphire Crystal protective glass. It is also waterproof up to 50 meters and can dial into WiFi networks as well as cellular networks.

 An integrated eSIM is installed for the latter. For smooth presentations and excellent loading speeds, the Apple Watch Series 5 is equipped with the Apple S5 chip and up to 1 GB of RAM. Thanks to 32 GB of internal storage capacity, you also have enough space for apps and media. A 296 mAh battery is installed so that the clock can last up to 18 hours a day. For athletes, there is a heartbeat and acceleration sensor, a barometer and a lot more on board.

Apple Watch Series 4

The Apple Watch Series 4 has been on the market since September 2018, but is still one of the best mobile phone watches with SIM. Like the new model, it is equipped with an OLED display that is protected by Sapphire Chrystal Glass. Furthermore, the smartwatch is water-resistant up to 50 meters and has both a WiFi and a cellular modem. Thanks to the integrated virtual eSIM, you don’t need to order a SIM card from your provider.

The Apple S4 chip, which uses up to 1 GB of RAM, ensures excellent performance. The internal storage capacity of 16 GB is somewhat smaller than in the new model. According to the manufacturer, the 292 mAh battery should last up to 18 hours. For sporting activities, the Apple Watch Series 4 has a heartbeat sensor, a barometer,

Samsung Galaxy Watch 3

Samsung also offers excellent smartwatches with SIM. The Galaxy Watch 3 is equipped with a Super AMOLED display, which thanks to Gorilla Glass DX is guaranteed not to get scratched or broken. The cell phone watch is waterproof up to 50 meters in accordance with the IP68 certificate and can dial into both WLAN and cellular networks.

A SIM card is not required for the latter, as Samsung has built an eSIM into the watch. The Exynos 9110 serves as the processor, which has up to 1 GB of working memory and thus guarantees fast work. The internal storage capacity is a bit tight at only 8 GB, but it should still offer enough space for all apps and media. The 340 mAh battery of the Galaxy Watch 3 promises a runtime of one to two days. Athletes come to the smartwatch thanks to the heartbeat sensor,

HUAWEI Watch 2

The HUAWEI Watch is already 3 years under its belt, but it is still an excellent smartwatch with SIM. The watch is equipped with an OLED screen that is protected by Corning’s Gorilla Glass. In addition, it is waterproof for up to 30 minutes at a depth of 1.5 meters according to the IP68 certificate. Thanks to the Snapdragon Wear 2100 chip and up to 768 MB of RAM, the smartwatch always works reliably.

The 4 GB internal storage capacity also offers enough space for the most important applications and media. So that you can access the Internet at any time, the watch has a WiFi and cellular modem. For the latter, however, you need a nano SIM card. Thanks to the long-lasting 420 mAh battery, the HUAWEI Watch 2 should also guarantee a running time of up to two days. For various sports activities, the watch is equipped with a heartbeat sensor.
