To use YouMail Visual Voicemail on your ROK Mobile phone, you will first need to determine whether your ROK Mobile device is operating off of the Sprint or T-Mobile/AT&T network so that your device will be forwarded correctly. You may need to contact ROK Mobile to find this information.
Once you have determined which network you are operating off of, download and set-up YouMail and choose ROK Mobile – AT&T/T-mobile or ROK Mobile – Sprint from the drop-down menu for your carrier.
The following is a statement by ROK Mobile, which can be found here:

ROK Mobile recommends YouMail for iOS and Android, available in the Apple App Store and the Google Play Store.

Native visual voicemail on phones purchased from another carrier may not work after moving your device to ROK Mobile.
Sprint phones: No, ROK Mobile does not support visual voice mail for our Sprint customers (conditional call forwarding is NOT available).
