The price of Starlink has reportedly been dropped in Europe and the US.
The new prices are meant to reflect parity in purchasing power, according to the email.
The event with T-Mobile is hosted by Musk.
The Starlink internet service is getting cheaper for some users.
Some Starlink users in the UK, Mexico, Germany, and Netherlands noticed that their monthly price for satellite internet had decreased.
Some of the new prices seem to be different. Some users said prices had fallen from as much as $124 to 105 and $105 to as low as 89.
Some users in the US said they had been told that their monthly cost would be reduced, while others said they had not. The monthly subscription price is $110.
"The price reduction factors in your local market conditions and is meant to reflect parity in purchasing power across our customers," the email said.
The company did not reply to the request for comment.
There will be price cuts on August 24, according to the email. Users who were notified of the price drop don't have to take any additional steps to qualify for the lower service costs according to the email.
On the day before the event with T-Mobile, the price dropped as well.
Starlink has a large user base. There are more than 2500 satellites in the company's network. The service is designed to deliver high-speed internet to customers in rural areas and high latitudes.
