Mainly due to health concerns related to COVID19, I decided to acquire an EasyPass ETC Device. I know that it works very well in Bangkok. However I remember very clearly that when you are reaching Pattaya if you are driving on the Bangkok - Chonburi expressway that exit toll only has signs which read "M-PASS". This combined with the fact that EasyPass belongs to BEM( BANGKOK Expressway Metro Company).... Makes me wonder whether I will be able to use the EasyPass on Pattaya and even other cities around the country. 

 

From forum searches it's pretty clear that M-Pass works in Bangkok. But I am not sure if the opposite case is true.

 

Thank you,

I believe they work interchangeably.
