What’s the difference between GPS and GPS + Cellular?
GPS
The Apple Watch Series 4 GPS lets you send and receive text messages, answer telephone calls and receive notifications when it’s connected to your iPhone via Bluetooth and Wi-Fi. The built-in GPS works independently of your iPhone for distance, pace and route mapping in workouts.
GPS + Cellular
The Apple Watch Series 4 GPS + Cellular has all the same great features as the above, as well as built-in cellular. It gives you the freedom to send and receive text messages, answer phone calls and even receive notifications when you don’t have your iPhone with you.

First phone bought online
This was my first experience of buying a used phone online, I've got to say I'm super impressed, it was only to tide me over until I bought a new one from Apple but now with this one having a 100% battery and perfect condition, I'm sticking with it and going to get my next one from Grade too.
