But there is one major difference between the two, and it’s in the form of their compatibility with CDMA networks. The A1688 model of the 6S is not compatible with CDMA networks, while the A1633 model is. This makes the biggest difference when it comes to selecting a sim free iPhone 6s. Despite their very minimal external differences, such as a small s logo on the hood of the A1633 model, Apple notes that this difference can be seen by clicking on a text link on their specs page for the particular model. The orgs wayback machine website has been helpful in archiving different tech specs for these iPhones over time and one can use it to further compare both models and see what other features each has or does not have.
The Iphone 6s comes in two different models – the A1688 and A1633. Both phones come with a 4.7-inch 750p display and a 5.5-inch 1080p display, but the key difference between the two lies in their displays. The A1688 has a 4.7 inch screen with a resolution of 750p, while the A1633 has a 5.5-inch display with the same resolution of 750p; however, each model offers different sizes plus sizes, so you have to look at their displays to find out which one is better suited for your needs.
The iPhone 6S A1688 is the smaller of the two models and is similar in size to the first generation iPhone SE, while the larger A1633 model is more comparable to the bigger Plus models. The A1688 has a 12-megapixel 4032×3024 pixels camera, while the A1633 has an 8-megapixel 3264×2448 unit. The rounded edges on both models make them look sleeker than their larger counterparts, but both are still relatively large phones compared to other iPhones. When it comes to features, both iPhones have a rear-facing camera that supports up to 12 megapixels and 4K video recording capabilities. However, the 6s+ model has a front-facing camera that offers 1.3 megapixels and 720p video recording capabilities. Both devices also feature Apple’s latest operating system iOS 10 and come with Touch ID for improved security. Overall, if you’re looking for a smaller iPhone SE or a larger iPhone 6S+, then both A1688 and A1633 are good options for you depending on what features you need most; however, if you need more features such as a better camera or bigger screen then you should opt for one of the larger models like the 6s+ which offers an 8-megapixel rear facing camera and 1.3 megapixels front facing camera with 1080p video recording capabilities.
The A1688 and A1633 both come with the current iOS 9 support, but the A1688 has more features such as a larger screen and better battery life. The performance of both models is similar, but the A1688 provides effectively identical performance when comparing them side by side. Both models are available through Verizon and Sprint which have different carriers’ bands, but you should go with whichever carrier has better coverage in your area for the best performance. The iPhone 6S A1688 represents particularly good value since Apple releases small mobile devices that still offer great performance similar to that of their larger models, while ignoring newer models like the iPhone SE and Plus models.
