WiFi Calling International Charges: The $75 Greece Bill (2026)

Wi-Fi calling abroad is free only when you call your home country. Dial a local number and Verizon bills it as international long distance, even with a day pass. On September 18, 2026, travel writer Zach Griff reported a $75 charge for Wi-Fi calls to Greek numbers. He was already paying for Verizon's $12-a-day TravelPass. Verizon credited it after he raised it.

The same week, Android Authority described full-day roaming fees for well under 200KB of data with roaming switched off. The fixes are cheap: call local numbers through a data app, block roaming at the account level, and move your data to a prepaid, data-only travel eSIM. If you only ever call home over Wi-Fi and your carrier includes roaming in your plan, you can skip to the section on phantom charges.

What happened this week

Three stories in six days describe how travellers get billed abroad while believing they are covered.

Griff's case is the instructive one. He had TravelPass on his backup phone in Greece. Some calls went out while the phone was on Wi-Fi, and it switched to Wi-Fi Calling on its own. His words: "because I was on Wi-Fi when I dialed Greek numbers, Verizon coded those calls as international long distance, not international roaming." The day pass he was paying for covered the same calls over the cellular network.

Does Wi-Fi calling cost money abroad?

Calling your home country over Wi-Fi costs nothing extra on all four big North American carriers. Calling anyone else, including a local number in the country you are visiting, depends on the carrier, and on Verizon it always costs extra.

Verizon

Verizon's TravelPass FAQ is blunt: "Wi-Fi calling isn't included with TravelPass. Wi-Fi calling to a country other than the US is charged international long distance rates whether or not you have an international travel plan." Its International Travel FAQs say the same.

Verizon's Wi-Fi Calling FAQs say a voice prompt reminds you of potential charges on these calls. If you hear it while dialing a local number, hang up and redial with Wi-Fi off. TravelPass lets you "call within the TravelPass country you're visiting", so the same call over cellular falls under the day pass.

AT&T

AT&T's international calling article, updated 26 August 2026, says Wi-Fi calls to non-US numbers are international long distance "even if you bought an international plan. If you're traveling abroad, this includes calls to the country you're in." It tells you to use Wi-Fi Calling only for US calls. AT&T's Wi-Fi calls article says the International Day Pass daily fee "includes Wi-Fi Calling to over 210 destinations". Until AT&T aligns the two, follow the stricter one: turn Wi-Fi Calling off before you dial a local number.

T-Mobile

T-Mobile's Wi-Fi Calling page charges nothing for calls and texts to US numbers. For non-US numbers while you are abroad on an unlimited plan, it points you to its 215+ destinations list for rates. Without an unlimited plan you pay World Class Calling rates. It also warns that if Wi-Fi drops mid-call, the call may switch to cellular, "This means unexpected charges if you're in another country."

Rogers

Rogers bills this one differently. Its WiFi Calling FAQ says an outgoing Wi-Fi call or message to a non-Canadian number "will incur the Roam Like Home daily charge". Later Wi-Fi calls in that 24-hour window ride on the same charge. So one Wi-Fi call to a local number opens a paid roaming day. Rogers adds that a VPN, DNS or internet provider set to another country can add long distance charges.

Why did you get a roaming charge with data roaming off?

Because "data roaming off" on your phone does not stop every byte. A day pass is billed per day, not per megabyte, so a few kilobytes cost the same as a full day of maps and video.

The Android Authority writer found "well under 200KB" recorded, "enough to trigger its full daily roaming fee". The Rogers user in the same article had a Galaxy S24 Ultra that logged 0.01MB on several days, with an $18 charge each time. The article's explanation: signaling or network registration traffic when the phone joins a roaming partner, or carrier policies that treat MMS or Wi-Fi-assisted services as roaming data.

Rogers' own roaming charges FAQ lists the everyday culprits. iMessage "may still send a message as an SMS or MMS if an internet connection can't be found." And "background app refresh, WiFi Assist, cloud-based backups or push emails can use data and result in roaming charges." Verizon's TravelPass FAQ says that once cellular data or data roaming is on, app refreshes, email sync and software updates can each start a session.

Here is what starts a paid day on each plan, from the carriers' own pages:

Opting out does not make Rogers free either. The same FAQ says that with Roam Like Home off and data roaming off, "You will be billed for roaming if you send a text message or make or answer a phone call."

How do you stop day-pass charges before you land?

Block roaming on the account, then back it up on the phone. Each layer below closes a gap the one before it leaves open.

1. Ask for an account-level roaming block before you fly. Android Authority calls it "the extra lock on the door": the network refuses the traffic whatever your phone sends. Verizon's own automatic block waits until you reach $500 in unbilled data, far above a $12 day.
2. Use airplane mode, then turn Wi-Fi back on. Rogers says airplane mode "disables all mobile connections" while Wi-Fi keeps working. T-Mobile warns that switching off data roaming alone "May still allow some types of data".
3. Turn off the fallbacks. Switch off Wi-Fi Assist, background app refresh, cloud photo backup and push email, the items on Rogers' list. On iPhone, go to Settings, Apps, Messages and turn off "Send as Text Message", the option Apple describes as making Messages try SMS when iMessage isn't available.
4. Check the Wi-Fi Calling icon before dialing a local number. On Verizon, hang up if the international-charges voice prompt plays. On AT&T, its own advice is to use Wi-Fi Calling only for US numbers.
5. Rate-limit downloads on Android. Android Police's tip: in Developer Options, set "Network download rate limit" to 256kbps and a 4GB pack takes "at least 4 hours and 20 minutes" to burn. This slows a runaway download. It does nothing about a day pass triggered by 0.01MB.

For local calls, use a data app such as WhatsApp or FaceTime over Wi-Fi or over travel-eSIM data. The carrier sees data, not a voice call to a Greek number.

Is a travel eSIM safer than a carrier day pass?

For data, yes. A prepaid travel eSIM has one price paid upfront, and no daily meter for stray kilobytes to trip. Rogers' roaming FAQ recommends the setup itself: set a third-party travel eSIM "as your primary SIM. This prevents your Rogers SIM from connecting to a roaming network and keeps roaming charges off your bill."

Lotsotravel is an independent travel eSIM provider, and its plans are data-only: mobile data, with no phone number, cellular calls or text messages. Calls go through apps, and your home number stays on your home SIM. Here is what the data side costs against a $12 day pass, at our live VIP prices on 25 September 2026:

The day pass figures include calls and texts on your home number. The eSIM figures cover data only. The Europe plan covers 33 countries, Greece included. For a trip that also involves an eSIM-only iPhone, see our iPhone 18 Pro eSIM-only travel guide.

To run both lines on one iPhone, follow Apple's Dual SIM guide: set the travel eSIM as the line for cellular data and keep "Allow Cellular Data Switching" off. When that switch is on, your iPhone can pull data from both plans depending on coverage, which is the leak you are trying to avoid. Then turn data roaming off on the home line.

Your home number stays reachable for bank codes. Rogers says that with Roam Like Home and data roaming off, incoming texts and unanswered calls are not billed. The Verizon and AT&T trigger lists name sending a text, not receiving one. Replying by SMS from the home line can still start a day, so reply in an app.

Where a travel eSIM does not help

• It does not fix Wi-Fi calling charges on your home line. Only dialing local numbers through an app, or with Wi-Fi Calling off, does.
• You get no local phone number, so a restaurant that insists on calling you back needs your home number or a messaging app.
• Answering a call on your home line abroad is a paid event on Verizon, AT&T and Rogers (opted out). Let unknown numbers go to voicemail.

Already charged? How to dispute it

Ask for a credit first, with evidence. Verizon credited Griff's $75 after he raised it. Gather three things before you call:

• The usage detail from your carrier's app or bill: date, time, and the kilobytes or call recorded.
• For a Wi-Fi calling charge, the number dialled and proof you held an active day pass that day.
• Screenshots of your roaming settings, if you had data roaming off.

Then work up the ladder if the first answer is no:

The CCTS lists "international roaming charges" for "pay-per-use services you did not use" among the complaints it handles. In the US, USAGov points you to your state consumer protection office or the FCC's online complaint form once your phone company has said no.
