Why ZERO11 Wireless appears to have ended
The sources do not say. The Wikipedia row lists ZERO11 Wireless as defunct but gives no date, cause or notes, and cites no reference.

Until a dated source turns up, the cause and the date stay open.
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.
