Best Buy said the WiFi/3G versions are available from Verizon and Sprint with a contract or a month-to-month plan.
The Best Buy news follows Verizon's pledge to sell the WiFi/3G model of the Tab Nov. 11 for $599 with no contract. Verizon Wireless customers can add a monthly access plan for the Galaxy Tab for $20 a month for 1GB.
This pricing surprised some analysts who were convinced the Tab would have to cost less than the iPad, which starts at $499 for the WiFi-only version and $629 for its WiFi/3G model.
Sprint may have taken this discontent into account Oct. 25 when it said that it would sell the Tab for $399 on Nov. 14. However, while Verizon is selling its Tab sans contract, Sprint is offering its machine with a two-year service contract on a 3G Tablet Mobile Broadband plan.
