I am looking to renew to either a 12 or 18 month SIM Deal.
It states that after 3 months I can upgrade to a Anytime Upgrade plan - If this was needed before hand would just the 3 months of billing need to be paid or the full 18 months?
Also, can I change SIM plan for more data if it isn't enough?
Current customers who change from refresh to a sim only plan can change tariff once every month and upgrade to a new refresh tariff at anytime they wish.
The 3 month alignment only relates to new customers.
