Ahahahah onexox is really confusing for newcomer especially regarding its data stored in season pass
I saw you already got some answers in onexox thread, but let me explain for others too
Think of season pass data as food stored in freezer, it wont decompose as long as it is frozen, same as your data stored when you purchase season pass, it does not have expiry date until your sim is unusable
When you want to use some data, you take out some of them from your storage. The moment you took some data out, it will be valid for certain days depending on what quota and its validity that you choose. The method to take some data out of your season pass storage is by dialing *150#, choose internet (3), and select subscribe from season pass (2), since your data is currently frozen and you need to thaw it this way.
The picture you posted above is season pass data, it will be stored and left untouched until you need to use them, you can take them out all at once or bit by bit
Regarding 600 days, since you planned on purchasing 10gb of data, the most value for money is to take 500mb out each time, and that 500mb is valid for 30 days. Therefore, you can take the data out 20 times, giving you 600 days of connectivity (as long as data isn't depleted, remember, onexox does not have basic data). Some plans have automatic recurring subscription, so remember to stop the plan from subscribing automatically if you don't want, but if you want the sim to always have internet connection, automatic is the way to go.
The above is only suggestions for people with low usage, your mileage may vary. If you ran out of data halfway, you can always take out some data with your current data validity, or subscribe new plan with new data validity.
Unlike data, calls and texts are immediately usable from season pass
Regarding to no2, I agreed, xox site needs to be revamped
This is even more confusing. Meaning i purchase a data pass I need to note the validity and again I need to ‘plan’ on how to use it?
Super stoopig marketing I would say. Why would they make the life of their users so tough while this can totally be simplified or follow the same ways as per other telcos.
