SpaceX is expanding the beta test of its Starlink satellite internet service, reaching out via email on Monday to people who expressed interest in signing up for the service.

Called the “Better Than Nothing Beta” test, according to multiple screenshots of the email seen by CNBC, initial Starlink service is priced at $99 a month – plus a $499 upfront cost to order the Starlink Kit. That kit includes a user terminal to connect to the satellites, a mounting tripod and a wifi router. There is also now a Starlink app listed by SpaceX on the Google Play and Apple iOS app stores.

“As you can tell from the title, we are trying to lower your initial expectations,” the emails said, signed Starlink Team. “Expect to see data speeds vary from 50Mb/s to 150Mb/s and latency from 20ms to 40ms over the next several months as we enhance the Starlink system. There will also be brief periods of no connectivity at all.”
