As of February 24, 2022, 2G and 3G networks will cease to operate in the United States. The switch will make some older phones and devices useless but will make way for more advanced services, including 5G. 3g usa

If you are going on a trip to the USA, then for the correct operation of your smartphone, you need to make sure that it supports the VoLTE service.

AT&T, which announced that its 3G network would go dark Feb. 22, 2022, says its shutdown is on schedule but did not elaborate on when the process would be complete.

T-Mobile says the 3G network that had been part of Sprint before the two companies merged will go bye-bye on March 31, and its own 3G UMTS network will be shut down July 1. T-Mobile also indicated that the former Sprint’s LTE network — which stands for Long-Term Evolution and is a flavor of 4G —  will be shuttered July 1.

Verizon plans to retire its 3G network on Dec. 31 after extending an original 2020 deadline. The company says it will not extend the deadline again.
