Scenario 1: When a new customer becomes an existing Three Business customer
If a new business customer buys 2 unlimited Boundless 24 month SIM Only plans during the Promotion Period, they will unlock our first discount tier of £12.50 per month (ex. VAT) per SIM. If this business customer comes back and purchases another 3 unlimited Boundless 24 month SIM Only plans during the Promotion Period, they will unlock our third discount tier and these additional 3 SIMs will each cost £8 per month (ex. VAT). If the customer also wishes to purchase 2 unlimited Boundless 12 month SIM Only plans, the number of existing 24 month unlimited Boundless SIMs is not taken into account when calculating discount to be applied. The customer will therefore unlock our first discount tier and the price per 12 month unlimited SIM will be £15 (ex. VAT).
Scenario 2: Existing Three Business customers
If an existing business customer already has 4 existing unlimited Boundless SIM Only 24 month plans, purchased prior to 30 October 2023, and they purchase an additional 3 unlimited Boundless 24 month plans during the Promotion Period, they will unlock our third discount tier and these 3 additional plans will cost £8 per month per SIM (ex. VAT, pricing based on 24-month contract). The 4 existing plans will remain on the pre-30 October 2023 pricing.
