It is not actually "legal" to receive the satellite signals of certain providers in the DR, so you cannot "legally" pay for them.
If you are just receiving true Free To Air signals you are stealing nothing. If you are getting a signal you have to pay for in the US and you cannot legally pay for it in the DR, then I will leave it up to you as to what to call it.
=============================================
I would call it a signal you are unlikely to be convicted of stealing.
