- US Mobile is introducing several improvements, including the new Multi-Network Functionality feature.
- This feature allows you to use multiple networks simultaneously on the same line.
- It will be free until March 31, after which it will cost $15 per month.
Earlier this month, US Mobile teased a major announcement for February 11. The only confirmed details were that it involved the Dark Star (AT&T) network and possibly new features like multi-network support. Now, the day has arrived. While we dive into the Dark Star changes in another article, the arguably bigger news is that the long-anticipated Multi-Network Functionality add-on is finally rolling out.
From now until March 31, you can add a second network to your US Mobile plan for better coverage at no extra cost with the new Multi-Network Functionality add-on. For example, you could combine Dark Star with Warp 5G, gaining high-priority data across both Verizon and AT&T’s networks without needing to perform a network transfer. You will still need a dual eSIM device for this feature, however.
