FAQ
Reader questions
Why do I see 3G or no data during phone calls even with LTE?
Your carrier or device may not have VoLTE enabled, causing calls to fall back to 3G and pausing data. Confirm that VoLTE is turned on in Settings and that your carrier supports it.
Why is my visual voicemail not showing new messages?
This can happen when cellular data or carrier settings are out of date. Ensure Cellular Data is on, update carrier settings, and contact your carrier to confirm VVM is provisioned on your line.
Why does call setup take longer than usual on LTE?
Slow call setup is often related to missing VoLTE activation or weak LTE coverage. Verify that HD or VoLTE appears in your status bar and check with your carrier about enabling VoLTE on your account.
Can I use LTE and VVM internationally?
Access for iPhone 4G LTE w/ VVM abroad depends on roaming agreements and local LTE coverage. Data and visual voicemail may work, but call features can vary, so review international roaming options with your carrier.
