How do i change my data plan to 100gb

[Joedward59]

Im going away and want to change data plan for 1 month or but one off 100gb

You can't buy that much as a one off.

Go to MySky > Mobile > Your SIMs > Manage SIM > Manage Settings > Change Data Plan

You can change the plan once a month.  (Increasing your plan is made available immediately, decreasing waits until the end of your billing period.  Billing may not be quite as you expect due to monthly in-advance billing but does work out pro-rata)

Looks like 25GB is the largest plan they currently offer.

The next tier up is 'Unlimited' - but you cannot roll that across other SIMs.

Indeed, you cannot roll data until the end of billing period and it is applied to your piggybank.
