Yes, new customers can order a free SIM through the VOXI Mobile website by providing their name, email address, and postcode (for a postal address lookup). Your SIM will then be sent by post, and can be activate online once you've received it. Delivery is free, and you just need to choose your plan to start your rolling 30-day subscription. If it's not for you, it's contract-free, so you can cancel anytime.
