ThingSIM at a glance

The facts

• SIMs arrive inactive. Billing starts when you activate, or automatically 30 days after we despatch your SIM; we email you at least 5 days before.
• UK 4-network plans roam across O2, Vodafone, Three and EE, from £0.90 a month per SIM for 50 MB.
• UK 3-network plans roam across O2, Vodafone and Three (no EE), from £0.65 a month per SIM for 50 MB.
• Plan sizes are 50 MB, 250 MB, 1 GB and 5 GB a month; 1 GB on UK 4-network is £2.40 a month.
• Each SIM costs £2.00 once: a multi-size SIM that pops out to mini, micro or nano.
• When a SIM uses its monthly allowance it pauses instead of charging overage; upgrade it straight away or wait for the reset.
• 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.
• No contract: pay monthly by card. Up to 25 SIMs can be ordered online; larger fleets are set up with us.
• Every SIM gets a private IP address; a static public IP is £8 a month. Private APN, IPSec VPN and cloud interconnect are available as extras.
• Europe (EU roaming) is priced per project.
