Astound Mobile Frequently Asked Questions
What is Astound Mobile?
Astound Mobile is a mobile virtual network operator that sells cell phone service on T-Mobile's network. It is a bundled add-on for Astound Broadband home internet customers, so a qualifying Astound Internet plan is required to sign up.
Who owns Astound Mobile?
Astound Mobile is owned and operated by Astound Broadband, the sixth-largest cable operator in the country. Astound Broadband is the trade name of Radiate Holdco, LLC, the company formed from the former RCN, Grande Communications, Wave Broadband, and enTouch Systems brands. The mobile platform itself is powered by a third-party software provider called Reach.
When was Astound Mobile founded?
Astound Mobile launched in June 2023, when Astound Broadband entered the wireless market using T-Mobile's network. The service first went live in Massachusetts and several Texas markets, then expanded to Astound's remaining territory across 12 states by the end of that year. The parent cable business is much older, built from regional providers that predate the mobile service by decades.
What network does Astound Mobile use for coverage?
Astound Mobile uses T-Mobile's network for coverage. That gives it access to T-Mobile's nationwide 4G LTE and 5G footprint. Astound does not own or operate any cellular towers of its own.
Does Astound Mobile have good coverage?
Coverage on Astound Mobile mirrors T-Mobile, so its quality depends on how strong T-Mobile's network is where you live and travel. T-Mobile tends to perform well in urban and suburban areas and can be thinner in rural and remote regions. As an MVNO, Astound Mobile traffic can also be deprioritized behind direct T-Mobile customers when a tower is congested. Check the coverage map for your specific address before switching.
What features does Astound Mobile support?
Astound Mobile supports:
- VoLTE
- MMS (multimedia messaging service)
