Changing tariff

[DC8]

I am currently on a Sim only, 40GB data pm, 18 month contract. An O2 email sent on 6th April advertised upgrading to a 50GB tariff for an extra £5 and that "You’re free to move your data down (or up) each month and there’s even tips below to make your data go further."

Clicking through the link on this email for this offer and there appears a message contradicting the email..."You can change to any of the following tariffs. It won’t affect the length of your contract but once you’ve changed you may not able to move back to your previous tariff or any extras that were connected to that tariff."

I'd like to upgrade the tariff for 2 or 3 months & then return to my original tariff - does anyone know if this is possible?

Mine wasn't due until July, but again, no fees.

My data renewed today - if I upgraded to the 100GB, would I still be charged for this month's (40GB) data?

@DC8 

No, the change will take effect on your next bill for billing purposes.

No you will pay the new tariff on your normal billing date with a slight adjustment either up or down depending on what you pay now.
