On the 3rd attempt leaving the phone outside in between rain showers I finally got a fix. This shows it can work without assistance, but it's not exactly quick or reliable. The assistance process is detailed in EC25&EC21_GNSS_AT_Commands_Manual_V1.1 - see sections 2.7 through 2.9, a d examples in 3.3. The file command used to upload the assistance data is in EC2x&EG25-G&EG9x& EM05_FILE_AT_Commands_Manual_V1.0 section 2.4. If assistance isn't already enabled it requires a modem restart too.
