Note that the iPhone 12 supports two types of 5G connectivity: mmWave 5G and sub-6GHz sub-band. At the same time, support for mmWave 5G technology will only be in models that are offered in the United States. They will also differ externally: an additional antenna will be located on the side of the case.

So far, the results of testing the iPhone 12 in AT&T, Verizon, and T-Mobile networks have appeared on the web. Tests were performed using SpeedSmart, a baud rate app available on iPhone and iPad. At the moment, only “a small number of tests” have been carried out in several large US metropolitan areas.
iPhone 12 owners who connected to Verizon in San Francisco received the highest download speeds – over 2 Gbps. In Chicago, this figure is less – from 1 to 1.5 Gbps.
The launch of fifth-generation networks in Russia is delayed. 5G’s priority frequency range 3.4-3.8 GHz is occupied by various services. The issue of releasing the frequency range of 4.8-4.9 GHz is now being dealt with by the Ministry of Telecom and Mass Communications. Currently, Russian telecom operators are testing 5G in other bands – 25.25-27.5 GHz and 4.9 GHz.
