I was in the USA (Whidbey Isl) and was connected to the home wifi network. After arriving back home I realized that I had incurred a fair bit of data usage while connected to WIFI. How is this so? I confirmed that my 'keep wifi while screen off' setting was YES.
Could be a few reasons, did you have data turned off? Even with data roaming set to off it is possible for data to leak before the system realizes you're roaming and shuts it down. For this reason, I recommend turning data off if you're not planning on using network data.
Hi, thanks. I'd been in the states for a day already. Memory is fading on the Data setting. Having read a few other posts it seems the phones are not dependable to focus data while connected to Wifi so I'll look into a data toggle widget.
