You can buy your access code at the camping reception or via Citymesh portal page.
Once you are connected to the Citymesh network (Citymesh Hotspot or, in case of Loco Pro, your SSID) you will be redirected to the Citymesh portal page. Just click on Buy an access code online:
Can I stop my code?
No, the code is active for the specified period from first connection. If you first used a 1-month code on May 10, it will only be valid until June 10.
Can I reuse my access code at another campsite?
Sure, no problem!
Can I buy an access code before arriving at the campsite?
At the moment, it's only possible to purchase a code when you are at the camping site, either at the reception or via the portal page. If you have an active code that hasn't expired yet, you can of course reuse it.
