Does a 4G smartwatch need a SIM card?
If you have a standalone smart watch or don’t want to use your smart phone cellular network or WiFi, your smart watch will need a SIM card for connectivity. If you’re happy to only use Wi-Fi, rather than mobile data, you’ll still be able to browse the web, access social media and stream video content without a SIM. If you wish to make calls, send messages and access 3G, 4G and 5G on the go you’ll need a SIM card and appropriate data plan.
Can I use a smart watch as a phone without a phone?
Yes, you can make calls from your smartwatch without a phone if you choose an LTE or eSIM model and activate a compatible plan. Apple Watch 11 GPS + Cellular and Samsung Galaxy Watch 8 LTE both deliver true standalone calling for everyday use. LTE shines if you ditch your phone often for runs or hikes. Is it worth getting an LTE smartwatch? Yes, if independence matters like calls or music without your phone nearby. Skip if you’re always paired up; extra cost and shorter battery aren’t worth it.
