Most of the time this error is caused by the connectivity of your phone to a cellular network or WiFi connection. The easiest way for solving this issue is by turning the Airplane Mode ON. On your main screen of the phone, you can swap down the notification bar and tap on the Airplane Mode option. Once it is ON all the connectivity to your phone will be turned off. You can wait for 30 seconds and then turn it back OFF by using the same method. This option can vary depending on the device you are using. For some devices, you need to go to settings or use the power button on the phone to get to Airplane Mode. After applying this method, you can now try updating or setting up the voicemail greeting on your phone.
Open your phone’s voicemail app, then tap (or in some cases, tap and hold) the message you want to save. You should be presented with a list of options; the save option will usually be listed as “save”, “save to phone,” “archive,” or something similar.
