No, we do not offer trial periods on our services.
The minimum term is 30 days so you would need to sign up for services and if you decide it is not for you then you just need to request cancellation on your online dashboard or email support@onsim.uk to cancel your services at least 48 hours before your account is due to renew.
If you have any questions please do not hesitate to contact our support team (support@onsim.uk)
