If you’re a “Pay As You Go” customer you may find that you have a special code to dial to get your balance – it might be *#10# or *101# etc. This program will sit on your homescreen and check how much credit you have remaining.
Available for both touch screen and non-touch-screen phones you can check manually, daily or hourly. It’ll also display the results in your local language.
Download the 7-day trial or grab it for €9.99 ($14.35 / £7.12).
