Preloaded is when you pay the total cost upfront, Pay Monthly Plus is when you pay 50% upfront, and the balance of 50% paid monthly over 12 or 24-months.
Preloaded and Pay Monthly Plus offer savings over Pay Monthly plans, which also have 1-month rolling plans, unlike Preloaded and Pay Monthly Plus.
At the end of the term, you can take out another Pay Monthly Plus plan, or any other SIM only plan from Mozillion. We will notify you at least a month before your plan expires so you can decide what to do.
