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 by default and 4G networks will be around for at least another decade. 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
