Effecting a sim downgrade

[Davidd0968]

I would like to/have downgraded a sim from unlimited data allowance to a capped level. The standard is that this won't be effected until the next billing date but this is 25 days away and I don't want to wait that long , I don't mind paying the higher tariff for the period even though it will be for the lower allowance, can sky do this?

All you can do is to call Sky on 150 to see if they will change your data allowance earlier than your billing date but don't be surprised if they say that this isn't possible.
