Hi to all

Just switched my ISP from totally unlimited (but very slow) to 150Gb per month (but quickish) 4G internet. I am hosting an S3 in my bedsit which actually is a nice little 400W heater now the nights are getting cooler here in Portugal. The question I can't seem to find an answer too is how much bandwidth does an S3 use in a 24 hour period? (up and down) I have Networx installed on my desktop and laptop which gauges the usage from computers but the S3 is connected directly to my 4G router so bypasses the monitoring.

Any help much appreciated. TIA
