IT'S NOT PAIRING WITH MY SAMSUNG SPH-A640 PHONE. IT RECOGNIZE THE UNIT BUT, NO PAIRING.

u can use data cable

go to menu, then phone profiles, then change the profile to anything other than offline. offline mode is also known as flight mode which allows you to keep your phone on while on board an aircraft.

hope this helps :)

sorry no.
the sph-a640 is a cdma phone and not compatable with sim cards

sprint.com usually has manuals online. Check under the support link.

dear,
first of all delete the searched blue tooth devices in the list and then try it again,
ask further if required,  before rating

regards,

Take the phone to the service provider and have them flash the phone...

Canadian Tire's HFBLU-LT100 (BK-600) won't connect to my SPH-m300 Samsung phone but I entry of the passcode (0000) about 20 times before it connect successfully.

Hi,

Change either ur LCD or FPC or both if needed. FPC is usually called as patta/connector.
