Many users have asked us this question.
Is Teracube compatible with 5G?
Teracube One and Teracube 2e are 4G LTE phones. Almost all 5G networks being deployed now or in the next few years will support 4G LTE by default. So yes - Teracube phones are compatible with almost all planned 5G networks - however, they will only work at 4G speeds. Just, do not expect Gigabit speeds
