Three carriers that offer the best small business cellular plans on the market today are Sprint-Nextel, AT&T and Regional Carrier Metro PCS. Sprint Nationwide CDMA Network has cellular voice, text and 3G/4G high speed data access. Sprints', Nextel product line, also offers the "Direct Connect" technology that is favored by construction, security and landscaping firms.
AT&T operates using a Nationwide GSM Network, which has most of the abilities of Sprint-Nextel's product, except the 4G data access at this time. The SIM Card technology that AT&T uses allows users to easily switch phones, by moving the card over into the new handset.
Regional pre-paid carrier Metro PCS operates off a similar CDMA network as Sprint-Nextel but offers regionally based unlimited talk, text and data services for one set price. No contracts are required for a small business to sign up for Metro PCS service and a small monthly discount is offered for up to 4 lines of service, each.
