How do I retrieve my voicemail while traveling outside the USA?

To retrieve your voicemail messages when roaming outside the USA, press and hold the voicemail retrieval key (typically the “1” key) on your wireless phone, and follow the prompts. Your screen may display your voicemail retrieval number. This number will differ from your wireless telephone number. When accessing your voice mail, you may be asked to reenter your wireless number. Doing so will play your voice mail greeting. If this happens, interrupt your greeting by pressing the STAR (*) key. You may be prompted to enter your voicemail password. This is the password you selected when you first set up your voicemail. Calls to voicemail from your wireless phone when roaming internationally are billed at international rates.

Note: When accessing your voicemail, you may notice that the number on your display is different than your wireless number. This number is the Voicemail Retrieval number. Quite often, the area code will differ from your wireless numbers area code. This is normal and will not result in additional long distance charges. Standard airtime and any applicable roaming and toll charges apply to Voicemail Retrieval and Return Calls from Voicemail. If your wireless number appears in the display, your phone should be reprogrammed with the Voicemail Retrieval number. Please contact Customer Service (611) while in the USA or International Care (+1.916.843.4685) while roaming internationally.

To do this select Settings > Options > Network. Change network selection to manual. Then click scan for new networks and select a network other than the one you are currently set on.
