Checking for Voicemail Messages While Roaming
When you are roaming off the network available to you, you will not receive
on-phone notification of new voicemail messages. Callers can still leave
messages, but you will need to periodically check your voicemail for new
messages if you are in a roaming service area for an extended time.
To check your voicemail while roaming:
1.
Dial 1 + area code + your wireless phone number.
2.
When you hear your voicemail greeting, press
3.
Enter your passcode at the prompt and follow the voice prompts.
When you return to the network available to you, voicemail notification will
resume as normal.
