You can delete individual voicemails as you listen to them, and most networks will automatically delete old voicemails after 30 days. However, few networks offer a simple way of deleting multiple voicemail messages when your mailbox is full – unless you can use an option such as Visual Voicemail, which lets you delete messages with a quick tap of your finger.
I have checked your account and I can confirm that the voicemail on your account can be disabled. But again, this might just get automatically enabled from time to time so you may have to contact us again to get it done. Again I apologize for the confusion and the delay in response. At US Mobile, we try our best to keep it transparent as much as we can. I hope this is understandable.

The biggest reason voicemail has become so passed? There are just better, faster, more convenient ways to get a message to someone: like via text, iMessage, or WhatsApp. Voicemail also takes a relatively long time to access. You can quickly glance a text message, but with a voicemail you often have to log into to retrieve the message and then listen to the sender ramble for dozens of seconds about something they could have conveyed in a text message that takes two seconds to read.
