i have an older samsung galaxy S plus 9001 and it worked ok on vodafone.
with the 2degrees though it can take up to ten seconds to actually connect a call..when i dial a number it just stalls and does nothing..............then finally i get the ringing tone after some time. this happens even with full reception.
also if i drive out of Tauranga to say whakatane or Auckland/Hamilton my data drops and i have to go to settings and search network opertors to get my data working again...
any reason why the poor performance etc???
