And a larger microsd limit. I would love such a device. I have given up on Ravpower’s filehub due to poor software. Does not need a phone modem.
E750 comes with an adapter to connect Wired devices.
So you want an E750 without modem, with larger microssd limit and ethernet ports… ?
That case you want an MT1300 (Beryl) 3 ethernet ports, up to 512MB sd-card and is smaller than the E750 (and maybe you need a 5V/3A battery pack though )
