Hi. I've had a system happily uploading data to VRM for a year or so now. It's via a PAYG sim and normally costs about 1p a day. Recently it has started doing a large upload of exactly 160mb once a week, every week, between 2am and 3am. This is quickly eating up the data allowance and costing a lot in extra charges. I cannot see what has changed or what is causing this behaviour. The data update rate is set to hourly intervals and is usually about 1kb. Something changed about six weeks ago, but I'm not clear what. It may be I've accidentally changed a setting. Do you have any suggestions?
