Geto Boys member Willie D has pleaded not guilty to 15 counts of wire fraud.
The Houston emcee was arrested in May for allegedly running an international iPhone scam.
Authorities claim that Willie D, real name William James Dennis, would conduct the scam through eBay by having foreign consumers make bulk purchases.
Once the electric wire transfer was complete, the victims were sent phony tracking numbers on packages that never arrived.
The rapper remains free after posting bond in May.
Under his release terms, the Houston native was required to surrender his passport and cannot travel beyond Harris County, Texas.
Willies internet privileges were also revoked; despite attorney Stanley Schneider initially arguing that his client needed internet access to manage his Hip-Hop career.
Willie D will appear in court for a pre-trial hearing on July 27, where jury selections are also scheduled to take place.
If convicted, the rapper faces a maximum sentence of 20 years in prison, and a fine of $250,000.
At press time, Willie D could not be reached for comment.
