Cellular vs Non-Cellular Smartwatches
One of the biggest decisions when choosing a smartwatch is whether to go cellular or not. Here is a simple breakdown:
How to Choose the Right Smartwatch
Five questions that narrow down your options quickly
1
What Phone Do You Have?
Apple Watch only works with iPhone. Samsung Galaxy Watch and Google Pixel Watch work best with Android. If you have an iPhone, the choice is Apple Watch. If you are on Android, compare Samsung and Pixel side by side.
2
Do You Need Cellular?
Cellular lets you make calls and stream music without your phone. If you run, cycle, or train without your phone, it is worth it. If your phone is always nearby, a GPS-only model saves money and lasts longer between charges.
3
Set Your Budget
Smartwatch deals on Switch start from under £20 per month. No upfront cost options are available on most flagship models. Paying something upfront typically reduces your monthly cost, use the filters on Switch to find the split that suits you.
4
Pick the Health Features You Actually Use
Every top smartwatch tracks heart rate, sleep, and steps. If you specifically want ECG or blood pressure monitoring, check Apple Watch Series 11 or Samsung Galaxy Watch 8. Sleep apnea detection is available on Galaxy Watch 8, an FDA-cleared feature that stands out in 2026.
5
Consider Battery Life
Apple Watch lasts about 18 hours, you will charge it nightly. Samsung Galaxy Watch 8 gives up to 40 hours, Galaxy Watch Ultra up to 60 hours. If charging every day feels like a burden, Samsung or Garmin suits you better.
