A recent speed test suggests a particular iPhone 17 model may have slower performance on T-Mobile's network.
Not all iPhone 17 models will be able to take advantage of T-Mobile's advanced 5G network.
Qualcomm's new X80 and X85 modems support 6-carrier aggregation for faster downloads and greater spectrum compatibility. Given the Samsung Galaxy S25 utilizes the Snapdragon X80 5G modem, it is expected that all iPhone 17 models, excluding the iPhone 17 Air, will also incorporate it.
The C1 modem only supports 3-carrier aggregation for downloads.
The X80 and X85 modems also support uplink carrier aggregation and uplink MIMO, unlike the C1. Consequently, phones equipped with Qualcomm's newer modems will experience improved upload speeds and increased capacity compared to C1 iPhones.
The iPhone 16 exhibits superior upload speeds compared to the 16e in countries with advanced networks, but the opposite is true in the US, depending on the carrier.
The iPhone 16e delivers faster upload speeds on Verizon and AT&T, while performance is similar on T-Mobile.
The iPhone 16e excels in areas with weak network performance resulting from distance from a cell tower or congestion. This is because users with low speeds often connect to low-band 5G, which has slower speeds but better penetration. During these instances, the Qualcomm modem's capabilities are limited due to a lack of additional spectrum to aggregate. This is more noticeable for AT&T and T-Mobile users, and less so for Verizon customers.
If you are a T-Mobile customer in an area with consistently slow speeds, the iPhone 17 Air may not be ideal. However, speed may not be a priority, or a thinner phone might be preferred.
If you are in a country with a capable 5G network, choosing the iPhone 17, iPhone 17 Pro, or iPhone 17 Pro Max will be more beneficial, as Qualcomm's modems can better utilize advanced networks, regardless of your carrier.
