Error 127 means the installer is unable to extract the necessary files. What's more, I don't think a mobile data plan is sufficient for downloading Creative Cloud desktop apps even under the best of circumstances.
See system requirements:
Please ensure your computer and internet meet or exceed the minimum system requirements to run Creative Cloud + OS + all other apps you intend to use. Check each one as they vary. You will need ample free disk space on your primary hard drive to install + additional HD space to use those apps efficiently. - https://helpx.adobe.com/creative-cloud/system-requirements.html
