I'm a user a user of Vodafone in the Netherlands. I'm able to data roam on other Vodafone networks in certain other countries for a fixed price per day for a quota. Basically for 2 euros per day I get 35MB. If I go over this quota the per MB charge is really high, over a euro. I can live with the charge for the quota and would use it when I travel but I'd like to find a method to warn me when I'm nearing the quota. I use 3G Watchdog with which I watch my monthly quota. I can make the quota monitoring period one day but the I lose the monthly monitoring. Does anyone have an app for me?
