What is WiFi Calling and How to Enable It (Dealer Setup Guide)

GET MORE TIPS HERE

Customers usually ask about WiFi Calling when they have one specific problem: “My cell signal is weak at home (or work), but my WiFi is strong.” That’s exactly what WiFi Calling is built for. This guide delivers WiFi calling explained in plain language, plus a simple setup process you can use in-store to reduce dropped calls, improve call quality, and keep customers happy.

WiFi Calling Explained: What It Is (and What It’s Not)

WiFi Calling lets a phone make and receive calls and texts using a WiFi network instead of relying only on the cellular tower signal. The call still routes through the carrier—so the customer uses their normal phone number, normal dialer, and (usually) their normal plan.

What it’s not: WiFi Calling is not the same as WhatsApp/FaceTime/Zoom calls. Those are app-based internet calls. WiFi Calling is carrier-supported calling that works through the phone’s built-in calling and texting.

Customer Benefits: Why WiFi Calling Matters

• Better calls in weak-signal areas: Great for basements, apartments, rural homes, and office buildings.

• Fewer dropped calls: If WiFi is stable, calls stay connected.

• Clearer audio: Many customers notice improved call clarity when the WiFi connection is strong.

• Reliable texting: SMS/MMS can work better when cellular signal is poor.

• Travel convenience: In some cases, customers can still call/text on WiFi when cellular coverage is limited (carrier rules vary).

Dealer tip: WiFi Calling is a “trust builder.” When you solve a customer’s home coverage problem without selling a new phone, they remember you.

WiFi Calling Setup: What You Need Before You Start

• A phone that supports WiFi Calling (most modern iPhones and Androids do)

• A carrier plan that supports WiFi Calling (most major carriers do; MVNO support varies)

• A stable WiFi connection

• Updated software (recommended)

• Emergency address set up (required by many carriers for 911/E911)

How to Enable WiFi Calling (Step-by-Step)

Enable WiFi Calling on iPhone

1. Go to Settings > Cellular (or Mobile Data).

2. Tap Wi-Fi Calling.

3. Turn on Wi-Fi Calling on This iPhone.

4. Confirm or enter the Emergency Address if prompted.

Enable WiFi Calling on Android (General Path)

1. Go to Settings > Network & Internet (or Connections).

2. Tap Mobile Network (or Cellular Network).

3. Find and enable WiFi Calling.

4. Confirm or enter the Emergency Address if prompted.

Dealer tip: Android menus vary by brand. If the customer can’t find the toggle, use Settings search and type “WiFi Calling.”

How to Confirm WiFi Calling Is Working

• Turn on Airplane Mode, then turn WiFi back on (this forces WiFi-only connectivity).

• Place a test call.

• Look for indicators like “WiFi Calling”, “Vowifi”, or carrier text such as “AT&T Wi-Fi” or “T-Mobile Wi-Fi”.

If the call works in Airplane Mode with WiFi on, WiFi Calling is active.

Common WiFi Calling Problems (and Dealer Fixes)

• WiFi Calling toggle missing: Phone may not support it, carrier may not allow it on that device, or the phone may be carrier-locked/incompatible for BYOD. Update software and confirm carrier compatibility.

• WiFi Calling won’t activate: Check for a carrier update, confirm E911 address, restart the phone, and verify account provisioning.

• Calls sound choppy: It’s usually WiFi quality. Test on a different WiFi network, move closer to the router, or recommend a WiFi 6/mesh upgrade.

• Texts still fail: Confirm MMS settings/APN (especially on Android/MVNOs) and ensure the line is provisioned for SMS/MMS.

• Customer expects free international calling: Set expectations—WiFi Calling uses carrier rules. Charges can still apply depending on plan and destination.

Dealer Recommendations: When to Suggest WiFi Calling (and When to Suggest an Upgrade)

• Suggest WiFi Calling when the customer has strong WiFi but weak indoor cellular signal.

• Suggest a router/mesh upgrade if WiFi is weak in parts of the home (dead zones cause choppy WiFi calls).

• Suggest a phone upgrade if the customer has an older device that lacks WiFi Calling, VoLTE, or modern band support.

• Suggest a carrier change if the customer’s coverage is consistently poor everywhere—not just indoors.
