I just switched to straight talk, I have a samsung galaxy rugby pro i547, I am trying to set up voicemail... dialing *86 does not work - says my call cannot be completed. Dialing 1 does not give me any options to set up my voicemail. I am wondering how to set it up? Also, again, just switched to Straight Talk but my internet is SLOW... I don't have overly high expectations but it is slow by any standards... any ideas on settings to make sure it is as fast as it can be?
