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.

Excellent
This is my first time using Grade Mobile, and it won't be my last. I've used other companies before and some will just low ball you just to try and see how desperate you are for your payment. But this company gave me a quote and honoured it.The phone was exactly the condition I claimed it was, and they payed me what they promised for that condition. Easy, quick and hassle free.10/10 experience. 1000% reccomended.Math BOrder Number - 216187Thanks again!

Best offer for my iPhone 14 Pro Max
I had a great experience and had the best offer for my iPhone 14 Pro Max. Everything was done online and went smoothly. I will recommend Grade Mobile anytime. My Order No. was 215681Ehiorobo

First and foremost
First and foremost, it’s a refurbished iPhone 11 Pro Max circa 2019 release date. Packaging was second to none, very similar to Apple, came with a handy cable, nice touch. The phone itself was flawless, no scratches, battery health @ 82% slightly disappointing but not a deal breaker. Screen is an aftermarket but works seamlessly. Also an additional 12 month warranty which was a nice surprise. Purchased through Amazon.

Order 299937
Order 299937Fast delivery, item as described: heavy wear refurbished iphone 11 - seems in working order, just some fairly deep scratches on the screen (as expected from "heavy wear"). Only issue, (which hopefully won't present any actualy problems) is the message appearing saying "Unknown part: the battery for this iPhone is not recognised. An apple authorised service provider can repair or replace the battery to restore full functionality".

Order # 215778. The whole process was very smooth. I was sent a prepaid envelope to pack my old mobile. I was sent full tracking details and updated throughout the entire process. I received an offer and the payment was made to my account within minutes.
