Expo Mobile was a US mobile virtual network operator with monthly plans on the Sprint and Verizon networks. In early December 2018, Selectel Wireless took over its customer service. Wikipedia now lists Expo Mobile as defunct but gives no end date. Its website stopped working, with an expired security certificate.
Expo Mobile is gone
The brand no longer operates. In early December 2018, subscribers got texts telling them to call Selectel Wireless, which took over Expo’s customer service, according to BestMVNO. Wikipedia lists the brand in its defunct table with the end date marked unknown. It notes the site had broken links and a security certificate that expired on February 14, 2018. No source gives a final shutdown date.
If you had an Expo Mobile line
Expo Mobile customers were sent to Selectel Wireless for support and refills starting in December 2018. No source we read confirms whether Selectel still serves former Expo lines. If your number still works, ask the carrier that bills you today for your account number and transfer PIN before you switch.
How Expo Mobile ended
- March 2016: Sprint shuts down its WiMAX network. BestMVNO notes the brand still listed a Sprint WiMAX plan in late 2018.
- May 2017: Expo Mobile’s Twitter account goes inactive, per a December 2018 NWIDA post.
- February 14, 2018: The security certificate on the brand’s website expires, per Wikipedia.
- July 2018: Expo Mobile stops posting to Facebook.
- Early December 2018: Subscribers are told to call Selectel Wireless, which takes over Expo Mobile customer service.
Why it ended
No source we read gives an official reason. BestMVNO reported in December 2018 that Expo’s social media had gone quiet, its plans were dated and not competitive, and it still advertised a plan on a Sprint network that closed in 2016. The author speculated that handing customer service to Selectel Wireless was a first step toward closing. Those are a reviewer’s observations, not a confirmed cause.
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 this page
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. This brand counts in our tracked total, not in our active total, so it does not appear in tools built for live carriers.
