Rogers Wireless is a wireless telecommunications provider offering mobile phone and data services throughout Canada using Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS) technology. It is a wholly owned subsidiary of Rogers Communications.

As of Q3 2011, Rogers is Canada's largest cellphone provider with a subscriber base of over 9.2 million. This number includes 2 million Fido Solutions subscribers, representing over 21% of Rogers' mobile services subscribers. In urban regions, Rogers' Chatr brand offers only prepaid service, but it is unknown how many subscribers use this service. Taking into account all three of Rogers' mobile brands, there are 7.5 million or 81% on postpaid and over 1.7 million or 18% on prepaid.

The operator currently operates 3GPP Long Term Evolution (LTE), High Speed Packet Access (HSPA) and GSM networks in Canada.

Rogers began with an Advanced Mobile Phone System (AMPS) network, and later moved to the IS-136 standard before finally introducing a GSM network in 2001. At various times the service was sold under the names Cantel, Cantel AT&T, Rogers Cantel AT&T, and Rogers AT&T Wireless. Their network is GSM standard with development currently focused on UMTS, High-Speed Downlink Packet Access (HSDPA), and EUL service. Both the AMPS and IS-136 networks have been decommissioned; they were shut down on May 31, 2007.
