Hello lempicka303
Yes, you can control Spotify and read Whatsapp messages. However, you can only reply to Whatsapp with predefined messages. It is important to note that these functions only work in combination with the smartphone via Bluetooth. The watch is not compatible with an E-SIM
Yes, the Huawei Watch GT3 (42 mm, Plastics, Steel, One size) has a pedometer function. This sports watch and connected watch includes features for tracking physical activity, including measuring steps, distances covered and calories burned.
The 42 mm watch requires watch straps with a 20 mm bridge width, the 46 mm watch requires watch straps with a 22 mm bridge width. ALL watch straps in the respective widths will work. Greetings
Hello Nadine
You can activate the notifications in the Health app. To do this, go to the "Devices" icon in the app, press on your picture with the watch and then you can select the apps from which you receive notifications on the watch under "Notifications". Is this answer helpful for you? LG Melanie
Hello, no, neither is possible. Google Maps is only possible with a Google Wear OS smartwatch. Like Samsung Galaxy Watch4 or 5, Fossil, Mobvoi TicWatch. Greetings
Unfortunately, we are not in a position to judge this, but if there is any suspicion of a material defect, the watch can be sent to the Service Centre.
Unfortunately, we do not have any matching straps for this watch. However, you should find some offers on the web. I wish you good luck in your search.
