==Sunset for D-AMPS in the US and Canada==
[[AT&T Mobility]], the largest US carrier to support D-AMPS (which it refers to as "TDMA"), had turned down its existing network in order to release the spectrum to its GSM and [[UMTS]] platforms in 19 wireless markets, which started on May 30, 2007, with other areas that followed in June and July. The TDMA network in these markets operated on the 1900&nbsp;MHz frequency and did not coexist with an AMPS network. Service on the remaining 850&nbsp;MHz TDMA markets was discontinued along with AMPS service on February 18, 2008, except for in areas where service was provided by [[Dobson Communications]]. The Dobson TDMA and AMPS network was shut down March 1, 2008.

[[Rogers Wireless]] in Canada removed all 1900&nbsp;MHz IS-136 in 2003, and has done the same with its 800&nbsp;MHz spectrum as the equipment failed.  On May 31, 2007, Rogers Wireless decommissioned its D-AMPS (along with AMPS) networks and moved the remaining customers on these older networks onto its GSM network.

[[Alltel]], who primarily used [[CDMA2000]] technology but acquired a TDMA network from [[Western Wireless]], shut down its TDMA and AMPS networks in September 2008.  [[US Cellular]], which by then also primarily used [[CDMA2000]] technology, shut down its TDMA network on February 10, 2009, the last in the United States.
