Because of T-Mobile and Verizon, the iPhone 11/Pro/Max support an LTE band record

After all, the North American A2161 version has to support the exclusive FirstNet band for government employees and emergencey services, AT&T’s band 14, as well as T-Mobile’s vaunted band 71, the long-range 600MHz.
The international type of the three new iPhones includes band 28 that is all the rage in places like Europe, and it has even more – 30 LTE bands – so Apple has you covered in terms of coverage, whichever region you happen to be in.
Apple has achieved this feat by fine-tuning Intel’s newest XMM 7660 modem (there was no time to plan for anything Qualcomm after the lawsuit was settled) that is a tad slower than the Snapdragon X24 one that is in most Android flagships in the US – Cat. 19 and 1.6 Gbps versus Cat.20 and 2 Gbps.
Here are all the models and bands that the iPhone 11, 11 Pro, and the 11 Pro Max are equipped with.
