CTC Wireless was the cellular brand of CTC Telecom, Inc., a phone company in Cambridge, Idaho. It ran its own CDMA network and started PCS service in September 2001. Wikipedia’s list of former US network operators says it exited the wireless business in 2019. Its mobile network code was returned in October 2021.
CTC Wireless is gone
CTC Telecom, Inc. did business as CTC Wireless. Its Idaho annual report says its PCS wireless service started in September 2001. Wikipedia lists CTC Wireless among former US mobile network operators, with CDMA2000 voice, EV-DO and LTE data, and an end date of 2019. The note reads: exited wireless business. The US IMSI administrator’s record shows its mobile network code returned on October 21, 2021.
If you had a CTC Wireless line
No source names a carrier that took CTC Wireless customers. The sources do not say CTC Telecom moved cellular lines to another provider. A number left on a closed CTC Wireless account cannot be ported out through the old service today. Ask your current carrier whether it can be recovered, or start fresh with any carrier that covers your area.
How CTC Wireless ended
- September 2001: CTC Telecom starts PCS wireless service, per its Idaho annual report.
- June 1, 2007: CTC Telecom, dba CTC Wireless, receives its mobile network code (IMSI) assignment.
- 2019: CTC Wireless exits the wireless business, per Wikipedia.
- October 21, 2021: CTC Wireless’s mobile network code is returned to the US IMSI administrator.
Why CTC Wireless ended
The sources do not say why CTC Wireless ended. Wikipedia records only that it exited the wireless business in 2019. CTC ran its own CDMA network, so leaving meant shutting down towers and equipment, not just ending a resale deal. The parent company kept operating: CTC Telecom filed its 2020 annual report with the Idaho Public Utilities Commission from Cambridge, Idaho.
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 CTC Wireless
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. CTC Wireless counts in our tracked total, not in our active total, so it does not appear in tools built for live carriers.
