About sim
co:sim sells eSIM data plans for travelers, covering more than 200 destinations around the world. Instead of waiting for a physical SIM card to arrive, you buy a plan online and activate it on your phone straight away, which makes it a fit for last-minute trips as much as planned ones.
Plans come with a self-service refund window of 30 days, so if a plan turns out to be the wrong fit you can request money back within that time through the site itself rather than contacting support first.
There's no co:sim coupon code available at the moment; we check every day and add one here the moment it's live.
