Mobile Data Usage Accuracy
Hello,
I recently did a carrier switch and the new carrier reports way higher data usage that I'm used to.
I usually never checked the mobile data usage in the settings, so I don't have any experience on how accurate it usually is. I always had 3GB included and reached approx. 1-2GB maximum.
So, I recently reset the statistics to compare the unusual high figures reported by the carrier and it turns out:
My phone shows 40MB data transfer while my carrier bills me 300MB transfer!!!
I asked the carrier and they said that their figures are correct and their counts are what matter. They also told me, that I should give up comparing it to the mobile data usage reported by my phone as this is not accurate at all.
I'm aware that there are some circumstances why the carrier figures are higher, e.g. their billing rounds up to the next full 64kB, transmission errors that cause resends etc. I would expect 10% higher figures, or maybe 20% higher, but in my case it's nearly tenfold!
Has anyone experienced something like this before or knows how to solve this? How much off are the statistics for you?
