I have a pay as you go tariff that activates when i put £10 in my account, i want to add the £6 500mb data bolt on for a month without activating the tariff, how can i do this when the minimum amount i can put in is £10.

You need to top up and buy the bolt on before your anniversary date. It won't take the £10 bundle charge until then, but can't anyway if you have already spent £6 0n the bolt on.
If you are already passed your anniversary date you will need to do 2 £10 top ups.
