I did enroll in the PayByCar program and I have my E-ZPass transponder mounted on my windshield but I did not get a SMS message on arriving at the site. Why?

Some possible reasons why you are not getting the on-arrival SMS message include: Reason 1: Your E-ZPass transponder may be out of battery and could have stopped working. We recommend that you email us at with your transponder number and let us know. We will check our logs and get back to you with our findings. Reason 2: If you are driving any of the vehicles listed in the link below, we may have some difficulty reading your transponder tag on arrival at our site.;jsessionid=0000g570svmonc7BCAJI8NQHa2e:-1?id=extTags
