I'm the same as you Wispa.I had a digi phone but I took out the sim for a while and then when I ready to put it back in the phone apparently the sim got damaged cause don't matter what phone I put it in,it just keeps saying insert sim,since then I never buy back a digi sim and yea bmobile's gprs service is severly lacking in that you only have access to buzz.However I also have access to their gprs internet and even that is of poor service to me 5KBs,come on bmobile,digicel's gprs network is 4 times faster.
Bmobile's call conferencing feature is an iffy feature on my phone in that it works when it wants to and it's impossible to get it to work when my lime starts at night.
All in all I still prefer bmobile since digicel's calling prices are a killer.
