If u MNP into onexox, you will get 28 months validity. All season passes that you buy will go into 3 storages: minutes, sms, and data. These storage would have the same validity as your number.

So long as your number is active, all the stuff in storage would remain active. Minutes and sms in storage would be utilized as you make calls and send sms.

Should you not have any minutes and sms in storage, the normal call/SMS rates would apply. However for data, there's a slightly different rule. For example, say you buy a season pass with 10GB of data.

At any time you have two choices to use data. Firstly, you can subscribe data promo. Eg, data promo 1.5GB for RM28. If you choose this method, the system would deduct your credit.

Secondly, you can also choose to utilize the data inside the storage (from the season passes that you have bought previously). You can opt to use daily, weekly or monthly data. For example if u pick monthly 2GB, the system would deduct 2 GB from your data storage. No credit would be deducted.

If you have reached one month, and you only utilized 1.5GB of the quota. The balance, ie 500MB would be forfeited.

If you have used more than 2Gb, I'm not sure if you can utilize more data from the storage or not. Perhaps other users can clarify on this matter.

To be honest, onexox should hire somebody to make their system easier to understand. It takes me quite a while to read about it in this lowyat forum. Not user friendly at all. An average Joe won't have the patient to deal with this kind of telco, it's too complicated.

Xox block us from sending SMS to these numbers, to avoid scam. The only thing u can do is the activate via calling the bank.
