Purchased boost voucher of $10 last Friday. Had been told that would give me limitless data and calls for 7 days. It lasted less than 24 hours. Hesitant to put in new $10 voucher, as on limited funds. And was hopeing that the same wouldn't occur. Am I safe to enter recharge. Will I get what I had been informed last time . 7 days unlimited. Please concur. Thankyou
