The short answer is no, it does not. It's primarily just put in the name for marketing purposes because the PR departments have done their job and trained people to think that they need 5G or that 5G is "better" somehow.

A phone with 5G in its name is thus no different than the vast majority of the other iPhones, Samsung or Pixel devices that simply do not have 5G in the name.

Nearly all phones manufactured over the past 5-7 years have the ability to receive 5G signals, however the definition of what 5G actually is has been confused greatly by the carriers. The scary bad 5G technology we definitely should be concerned and afraid of is only deployed in a few major cities across the US right now, costs A LOT to deploy, and is simply not needed for 99% of the country. When carriers speak to their "Nationwide 5G Coverage" they are primarily referring to a rebranded Multi-point 4G LTE service that sends data to your phone from multiple towers vs a single tower.

For more details on exactly what 5G is, and is not, I recommend reading this post on the topic and exploring the links within: https://truthinlove.substack.com/p/emf-and-5g-current-realities-and

If you are truly sensitive to EMF from mobile phones and related devices that send and receive these signals, there's honestly no good mobile phone solution that will "eliminate" the radiation sent and received from mobile phones. If your body is allergic to water... you stay away from the water.

Many who are sensitive have found relief pulling the wireless Network Interface Cards (NICs) out of their "smart" devices around the house, connecting everything via ethernet and using various other modalities... but the MOST effective solution is to get away from the city entirely, move to a rural area that has very little/poor coverage and get back to using simple landlines for phone and internet needs.
