Good day to you! I hope you have a fun and safe trip. I'm sadden to say that there is not a way to check voicemail on the internet. You can always check your voicemail if you dial your own number from a landline. Once your voicemail greeting comes on you can press # right away and enter in your password. This could be another way of checking the voicemail so you don't have to use your cell phone to do it. I hope this was able to answer your question.
