VoiceStream - about us

GSM's proven feature-rich, dominant digital technology and use of "smart cards" (also known as SIM cards) enable North American GSM carriers to provide thorough customer service, call privacy, and fraud prevention. Only GSM provides integrated voice, high speed data, fax, paging and short message services capabilities. In GSM networks, full digitally encrypted wireless communications enhances confidentiality of voice and data calls.

In addition, North American companies using GSM technology offer excellent voice quality. Independent laboratory and field test reports validate near wireline parity. The larger number of vendors making GSM handsets and infrastructure worldwide, offers competitive, economical ways to keep costs down and gives consumers more choices.
