What is SIM activation?

You’ve received your Landline SIM and now you want to start using it, but first you’ll need to activate it.

Generally we try to activate SIM’s within an hour during office hours (Mon-Fri 9-5) but it can take longer depending on network restrictions outside our control.

If you are having problems locating your SIM ID number or activating your SIM please contact support at support@onsim.uk
