i recently switched my sim card on my LG C1300 with my new Sony Ericsson Z500 ( i was switching phones with someone.) and now, neither of the voicemails on the phones work. what happens is, on both the phones, i dial the voicemail #, and a prompt asks me to enter my voicemail # of the person i am calling. so i enter my phone #, but it says it cannot find my number. why is this?
