Amp'd Mobile has deep financial problems and filed for Chapter 11 BK protection in June 2007. The word is that the company hasn't been able to collect on bills owed by about one-half of its small customer base. Only the major carriers like Sprint-Nextel, AT&T and Verizon Wireless have their own networks. The 38-40 small U.S. companies like Amp'd lease networks. Amp'd leases Verizon Wirless' networks and caters primarily to teens and young adults using data content.
Potential subscribers might be better off looking for service elsewhere and current subscribers are enouraged to email or write the company to find out if and when Amp'd will be out of business. News reports indicated that Verizon Wireless did not cut the company off yet. With an unknown future, it's best to err on the side of caution.
