Contact your operator before your subscription expires to renew it;
If you fail to renew your subscription, the device will not send geolocation data to the e-TOLL system and no toll will be charged, which makes you liable for not paying the toll;
Failure to renew your subscription may also result in de-registration of the device by the On Board Unit/External Localization System operator, which will automatically deactivate and remove the device from the e-TOLL system and your OCA.
