Hi ,
I purchased a Samsung a21s on a contract with you and have had problems with it calling, on all calls it breaks up,the other people on the other end of the call says it goes robotic voice and then lose voice altogether.
I have had the phone back to Samsung 2 times and they have sent it back OK both times ,also when I take the sim card out and put it in another phone it is working OK and never get these symptoms.
Getting very frustrated with it .
Any help will be appreciated
