Images fro DSLR to the cloud

Hi All. My camera takes a full size SD card and in my travels I want to send my RAW files to my Google Drive. I want to conserve weight so I would like to use My Galaxy TAB S to handle the upload. It does not use a full size SD Card so I was hoping that someone on this list is doing the same thing. I will be taking a pocket Wireless Modem for use with a data plan and sim in the destination country. Hoping for 4G. Any clues would be gratefully applied. Andrew Greig
