My wife and me have the same provider. We have the same phone, we are conncected into the same home-WLAN. The last week, both phones lay side by side the last 7 days, while watching the vids:
-) my wife got 25 packs
-) I got only 13-17 packs

Again... the only difference is the phone number by one number... and that can't be a difference up to 12 packs...

I'm now interested, what ridiculous answer will come... if there comes an answer...
