How does billing work?

You pay monthly, in advance, from the day your plan started: join on the 20th and your next bill is on the 20th of next month.

Simp is paid in advance, starting from the day you join.

Your first bill covers a whole month from the day you join, or a whole 3 months if you pay upfront. No part-months.

Then it renews on the same date. Sign up on 20 September and your next bill is on 20 October, then 20 November, and so on (every 3 months instead if you pay upfront). Joined on the 31st? In shorter months your bill comes on the last day of the month. It renews by itself with the card on your account, so your line and your simp never stop by surprise.

Changes part-way through. Moving up a plan or adding an extra, like an extra AI number, starts straight away, and you pay only for the rest of your current billing period. Moving down a plan, switching between monthly and upfront, or cancelling takes effect at the end of the period you've paid for.

No contract. We keep you by being lovable, not by locking you in. Cancel any time: see How do I change or cancel my plan?

Want to pay less per month? Simp+ and Simp Pro can be paid 3 months at a time for a lower monthly price. Simp AI can be paid upfront too, at the same price. See Can I pay upfront?

Got a code? Codes are entered at checkout on simpmobile.com, and you can combine more than one. There's nowhere to enter a code in the app.
