Good morning vasqufr,

You should be able to call our regular sales line, provide them your current HughesNet account information and add-on a service without a credit check. If the agent did inform you there would need to be another credit check when calling the sales line, please provide me the phone number you dialed if you still have it. 

It may be possible for me to order this for you without a credit check, so please look out for a private message from me later today regarding an order offer.

Thank you

Amanda
