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.

After receiving the postage pack, it took only one day to send the phone over, it arrived the next day after posting. It was graded the same day and received the money by the same evening. Really quick and easy and received a fair amount for the condition of phone I sent. Would recommend if you want to sell your phone on.

Return customer
#229236 - I previously used GradeMobile in 2022 and needed to recycle my current phone. My experience of them was positive last time, so I have returned again. This order was quick and easy. I forgot to accept the grading offer and got a polite handy reminder to review it. Within 20 mins the payment sent email was received. Thank you and I'll see you again in the future.

Grade Mobile - an efficient. streamlined service
Grade Mobile’s service is very well-organised - I received the return label by email immediately, returned the phone at no cost to me from the Post Office, and was kept informed by Grade Mobile at every stage of the process. Once I had accepted the offer, the money was quickly paid into my bank account. I think what I was offered was a fair price given the condition of my phone. My order number was 229437. I was given a small consideration from Grade Mobile for writing this review, but I was free to give an honest assessment of my experience, which this is
