A Samsung Acclaim unlocked should work with any CDMA carrier such as Verizon Wireless and Sprint. By default most cell phones comes locked to a certain cell phone carrier and you must unlock them with software in the case of CDMA phones such as the Samsung Acclaim. If you have a GSM phone or a SIM card version of the Samsung Acclaim then you can follow our GSM unlocking guides found throughout the site. Theoretically a locked Samsung Acclaim could be unlocked but currently I do not believe any vendors have software to do this model just yet.
Stay tuned as we learn more about the release of his phone and wheather it may come unlocked for a higher price, etc. Please feel free to leave your own opinion and comment on this topic. Thanks and God bless!
