just wondering with celcom wonderoam roam data. if we suddenly hook to their roaming partner (by accident) for few seconds and only few kb do we need to pay the RM 38 per day charge? if that the case was really terrible

if you can share your case. in my case it happen only once so rugi RM 38. The occasion was on the plane, put celcom sim card forget to switch off data. after few second straight turn on airplane mode. only few kb then charged RM 38 cannot imagined if this happen few times, how much i will be charged
