In simple words, there is no service which will provide you 1gb with calls/text at your expected price point. And as Michael commented on the question, you cannot purchase a US prepaid sim from US networks as they ask your SSN in most of the cases. You have to find someone living in the US and has a valid SSN to get you a prepaid sim under their name.
Apart from that, there are some very good international sim's which you can purchase with data and unlimited calls/text for your travel purpose like Lyca Mobile, Vodafone and others. But they charge you minimum of $25 to $30.
The best option would be to check with your existing carrier in your country if they offer you international roaming plans.
