UScellular has confirmed it will switch off its 3G CDMA network next month.
In a statement, the operator stated it will switch off its CDMA networks on January 14, 2024.
"When we shut down our network, 3G devices will lose service completely. We are committed to supporting our customers and are ready and available to assist you through this transition," said the company on its website.
During Q3 UScellular CEO Laurent Therivel said that fewer than 42,000 customers were still using the CDMA networks as of September 2023.
The operator started its 3G switch-off back in 2021, with its CDMA networks using 800MHz/1900MHz spectrum.
UScellular, which is the fifth-largest carrier in the US behind the big three and Dish, is estimated to have close to five million customers across the country.
The retirement of its 3G service will enable the operator to focus on its 4G and 5G networks instead, it added.
Earlier this year, the company was linked with a potential merger with Dish.
Verizon retired its 3G service at the end of 2022, becoming the last of the big three US operators to do so. AT&T switched off its 3G network in February 2022, before T-Mobile did the same a few months later.
