Although the vast majority of mobile phone users stateside might not be able to notice a meaningful difference between 4G LTE and 5G speeds yet (wherever the latter technology is actually available), the nation’s top wireless service providers have been committed to the industry’s next big step forward for a pretty long time now.
While that’s definitely true for AT&T, which has long aimed for a February 2022 halt of all 3G wireless services, T-Mobile has technically not come out with a specific end date of its own. Granted, January 1, 2022 has been bandied about in the rumor mill for quite some time now, but obviously, nothing’s official until it’s official.
That being said, it’s probably wise to take the leap sooner rather than later. As you can imagine, the 3G network will not be terminated all at once, which means a “degradation or complete loss of service” could happen in many places well in advance of the end of next year.
