How ThingSIM billing works
When billing starts, what happens at the data allowance, and what happens if a payment fails.
ThingSIM is billed per active SIM, per month, on a card. There is no contract and no charge for SIMs that aren't switched on.
When does billing start?
Billing starts when you activate, or automatically 30 days after we despatch your SIM; we email you at least 5 days before. SIMs arrive inactive, so you can order stock a few weeks ahead of an install. The only charge before then is the one-off £2.00 per SIM. Monthly plans are billed in advance.
What does a SIM cost each month?
Its plan's price, from £0.65 a month for 50 MB on UK 3-network or £0.90 on UK 4-network, up to £8.85 for 5 GB on UK 4-network. All your active SIMs are on one monthly card payment.
What happens when a SIM uses all its data?
It pauses. There is no overage charge and no surprise bill. You can upgrade that SIM straight away, paying only the difference for the rest of the month, and it starts working again; or leave it, and it resumes when the allowance resets at the start of the next month.
What if a card payment fails?
If a payment fails, we email you a Pay now link and retry the card once after 3 days. If it is still unpaid, your SIMs are suspended until you pay with Pay now, and no new SIMs can be activated while the account is in arrears.
Can I pay annually or prepay for an IoT SIM?
Not at the moment. Every plan is billed monthly by card, in advance, with no contract.
Can I stop a SIM?
Yes, from the portal. Pausing keeps the SIM and its number so you can turn it back on later; stopping it is permanent.
