AST SpaceMobile successfully tests cell-to-satellite calls transmitting video
According to press releases from both Verizon and AT&T on February 24, 2025, each has successfully tested cellphone-to-satellite video calls using the first set of satellites in AST SpaceMobile’s BlueBird satellite constellation. From ATT:
AT&T and AST SpaceMobile have successfully completed a video call by satellite over AT&T spectrum using the BlueBird satellites launched last September. These are the same satellites that will be used to start commercial service.
From Verizon:
Verizon and AST have yet again pushed the boundaries of what can be done with mobile devices by successfully trialing a live video call between two mobile devices with one connected via satellite and the other connected via Verizon’s terrestrial network connection.
The satellites will essentially act like cell towers in space, filling in all dead spots not reached by ground-based towers.
AST’s constellation is competing with Starlink, which has signed T-Mobile for its service. In addition, Eutelsat-Oneweb has just successfully tested using its satellite constellation for the same purpose.
I suspect that in time, when these satellite systems have been thoroughly tested and have become operational, they will allow these phone networks to begin decommissioning their cell towers on Earth, thus reducing their costs significantly and thus lowering the cost to their customers.
Readers!
Every February I run a fund-raising drive during my birthday month. This year I celebrate my 72nd birthday, and hope and plan to continue writing and posting on Behind the Black for as long as I am able.
I hope my readers will support this effort. As I did in my November fund-raising drive, I am offering autographed copies of my books for large donations. Donate $250 and you can have a choice of the hardback of either Genesis: the Story of Apollo 8 or Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space. Donate $200 and you can get an autographed paperback copy of either. IMPORTANT! If you donate enough to get a book, please email me separately to tell me which book you want and the address to mail it to.
Please consider supporting my work here at Behind the Black. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

”I suspect that in time, when these satellite systems have been thoroughly tested and have become operational, they will allow these phone networks to begin decommissioning their cell towers on Earth…”
I don’t. Maybe a few towers in remote locations, but not more than a tiny fraction of them. No system, operational or proposed — not even Starlink — has even close to the capacity to replace terrestrial cell towers. What these satellite systems will do is fill in the coverage gaps of existing tower networks. That’s a big deal and enough business by itself for multiple satellite systems.
