Just choose a chinese network operator so that an operator is chosen in "mobile operator" field and then disable "auto adjust traffic". You'll probably get a sms from your provider telling that a particular ussd code that network monitor app just sent is not available. Just ignore it and then all good. No more notification...
besides that my phone ate about 20mb today while im quite sure i havent download anything in particular, only thing that uses connection is gg (polish comunicator) that refuses to connect most of the time since update anyway.. my network settings are fine, app is cnnecting via wifi w/o problem. edge/3g wont let it connect tho other apps do.
i can use internet app but play store cant connect aswell..
