Wi-Fi Calling Not Working: How to Fix It
Get Wi-Fi calling working again on iPhone and Android, with carrier-specific tips.
Wi-Fi calling is the feature that saves you when cell signal is weak but Wi-Fi is strong, like in a basement office or a thick-walled home. When it refuses to turn on or won't place a call, the cause is usually a setting or a carrier requirement rather than a broken phone. Here's the order to check things.
First, enable it properly
Wi-Fi calling is off by default on many phones, and some carriers need a one-time setup before it'll switch on:
iPhone: Settings > Cellular > Wi-Fi Calling, and turn it on. You may be asked to confirm an emergency address, which is required.
Android: Settings > Network & Internet > SIMs or Mobile network, then the Wi-Fi calling toggle. Samsung phones sometimes put it in the Phone app settings instead.
If it won't toggle on, or it turns on then immediately fails, move to the next steps.
Update carrier settings
This is the fix that resolves most Wi-Fi calling problems. The feature depends on up-to-date carrier settings, and an outdated version simply won't let it work.
iPhone: go to Settings > General > About and wait a few seconds; if an update is available, you'll be prompted.
Android: check for a system update, which can include carrier-side changes.
After updating, toggle Wi-Fi calling off and back on.
Check the plan and the network
Two things people overlook:
Your plan has to include Wi-Fi calling. Most do, but some bare-bones prepaid plans don't. If the option is missing entirely, confirm your plan supports it.
The Wi-Fi network may be blocking it. Restrictive networks at workplaces, hotels, and public hotspots sometimes block the ports Wi-Fi calling uses. A quick test: if it works on your home Wi-Fi but not elsewhere, the other network is the problem, not your phone.
Still stuck?
If Wi-Fi calling won't cooperate after enabling it, updating carrier settings, and confirming your plan and network, reset network settings as a catch-all (Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings on iPhone; the equivalent reset on Android). If it still won't work, the feature may not be fully supported on your phone-and-carrier combination, which is worth confirming with your carrier directly, especially on a phone bought for a different network.
Frequently Asked Questions
- Why won't Wi-Fi calling turn on at all?
- The most common reasons are that your carrier requires a one-time setup step first, your carrier settings are out of date, or your plan doesn't include Wi-Fi calling. Updating carrier settings and confirming the feature is supported usually clears it.
- Does Wi-Fi calling work on any Wi-Fi network?
- Mostly, but some restrictive networks (certain workplaces, hotels, or public hotspots) block the ports Wi-Fi calling needs. If it works at home but not elsewhere, the network is the likely cause, not your phone.
