Services are dependent on a number of factors, see here for further detail. Plan Terms and Conditions apply – see here. A minimum top up of €15 required every 28 days. The offer will re-activate every time the minimum amount is applied. This means that a new 28-day term starts, the offer allowances are re-set and you will lose any remaining allowances from the initial top-up as there is no carry over of allowances.
