Is there a gadget capable of being a 4g(3g) router and wi-fi storage AT THE SAME TIME?

Question

network hardware

For a long time I have been using a 4g router from MTS (some kind of huawei), which distributes the Internet to my everyday devices. At the same time, I regularly use dropbox and google disk cloud storage. In principle, this router is also capable of accommodating an sd card and being a file storage, distributing them via wi-fi, but at this moment it is unable to be a router. And the battery that is installed in this router is not able to last at least a working day in continuous mode. According to this question: is there a device capable of storing files inside itself (sd card or hard drive), synchronizing these files with one of the well-known cloud storages (this functionality is not required, but very useful) and at the same time be 4g (at worst 3g) router? And to perform these functions at the same time. It would be perfect
