No voicemail notification.
I have an iphone 3GS with IOS 4.1(8b117) and modem firmware of 06.15.00. It was jailbroken when I bought it and I have no idea which tool was used. My issue is that I do not receive any voicemail notifications. I am in Costa Rica on the ICE network. I have verified that my voicemail settings with my provider have notification enabled. The service provider was unable to determine the cause of the issue and verified that my VM settings are correct. In addition, when travelling in the US, I was unable to receive VM notifications on the ATT network using a prepaid SIM. Is there anything that can be done to resolve this issue?
Thanks in advance for your assistance.
