MOSH Mobile was a private Indiana phone brand founded in 2006. It ran on the GSM network of Centennial Wireless. Wikipedia lists its end as 2012. By November 20, 2012, the MOSH Mobile website redirected to the official AT&T website. No source gives an exact shutdown day.
MOSH Mobile is gone
MOSH Mobile no longer sells or supports phone service. Wikipedia lists it as defunct in 2012. Its own Wikipedia article says that as of November 20, 2012, the MOSH Mobile website redirected to the official AT&T website. Service ran on Centennial Wireless, a GSM carrier. No source BestCellular.com found gives the exact day service ended or a public shutdown notice.
If you had a MOSH Mobile line
No source names a carrier that took over MOSH Mobile customers. The website redirect to AT&T is the only pointer. A MOSH line that went unused since 2012 is almost certainly closed, and the number may have been reassigned. If you still need a phone line today, pick a current carrier and ask for a new number.
The 2012 end date and the AT&T redirect come from Wikipedia only, and the MOSH Mobile article cites no references.
How MOSH Mobile ended
- 2006: MOSH Mobile is founded in Indiana, using Centennial Wireless’s GSM network.
- 2012: Wikipedia lists MOSH Mobile as defunct.
- November 20, 2012: The MOSH Mobile website redirects to the official AT&T website, per Wikipedia.
Why MOSH Mobile ended
No source BestCellular.com opened explains why MOSH Mobile closed. What is on record is short. It was a private company in Indiana. It used Centennial Wireless as its network. Wikipedia marks it defunct in 2012, and by November 20, 2012 its site pointed to AT&T. The reason behind that redirect is not stated in any source we found.
How to find who holds an old number now
- Check an old bill or payment record. It names the company that billed you last.
- Run the number through a carrier lookup tool. It shows the carrier that holds the number today.
- Call that carrier and ask for the account number and transfer PIN.
- Start the port from the new carrier. Never cancel the old line first.
Your right to keep a number
Number portability is federal law, not a carrier policy. The rule is the FCC’s: Portability: Keeping Your Phone Number When Changing Service Providers.
How we verified MOSH Mobile
BestCellular.com tracks active carriers and defunct ones. We keep both, because people still search for brands that no longer exist. Every fact on this page comes from the sources listed below, and we leave a detail out when no source states it. Where sources disagree, this page says so. If you can document a correction, tell us and we will check it against the sources.
Tracked and active are different counts on this site. MOSH Mobile counts in our tracked total, not in our active total, so it does not appear in tools built for live carriers.
