I'm a new Waze user in the UK. Have tried to use several other common Android options but right now Waze is looking like the pick of the bunch for me.

The following query might be answered elsewhere if someone could kindly point me to it.

I installed Waze, and then used it on a 50 mile journey (each way), where it faithfully did what was expected.

However, when I got back home and checked my mobile phone account I noticed that 150+ Mb had been sucked out of my mobile phone contract. The only explanation for that was Waze - there's nothing else going on which would suck data.

I'm on a 1Gb/month tariff, so 150Mb fits comfortably into what I am paying for. However, is Waze going to be sucking data out of my mobile phone account each time I use it?

This situation might have been a first-time situation to fill up a cache. If so, no problem. However I am concerned that it might figure it could pull (or push) data thru my mobile phone connection. Perhaps someone could kindly explain the situation?

Ta muchly!
