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.

Very professional service
Very professional service. Negotiated an acceptable offer for my old phone and payed very quickly. Even gave me the opportunity to earn a small reward for an honest review.
Joe
Efficient process
Efficient process, required a manual payment (I think due to my name on the bank account) and this was made immediately after being recognised. Very pleased. I have used other sites to sell my mobile and this is by far the best one. Thanks!

Everything went according to plan
Everything was explained well and followed through seamlessly and promptly. Although the valuation went down quite a lot from the original quote, I expected this and was happy with the final amount which once accepted was in my bank account within an hour. Great service. I was offered a small payment gesture to write an honest review from Grade Mobile but it was not conditional on whether it was positive or negative. GMB227372
