TravelPass or Day Pass billed with eSIM

Verizon and AT&T bill a day for an answered call, a sent text or background data, roaming off or not. Line off settings and disputing a phantom day.

You did the reading before the flight. The travel eSIM carries the data, the home line has Data Roaming off, Allow Cellular Data Switching is off, and you still got the text saying a 24 hour TravelPass session has started. Or the bill arrived weeks later with twelve Day Pass fees on it. The r/verizon and r/ATT threads are full of people in this position. The replies contradict each other.

Data roaming off protects you from data and from nothing else. Below is each carrier's own trigger wording, the ways a correctly set up dual SIM phone still registers usage, the settings that close those gaps, and what to say when a day was billed with no usage.

What a "day" actually is: 24 hour sessions, Eastern Time and bill cycle caps

None of the four US carriers with a day pass bills by calendar day. Verizon's TravelPass FAQ says a session "starts automatically when you use your device in a TravelPass country" and runs 24 hours. Two hours after it starts, Verizon texts you the end time. Use the line after that time and a new session starts. Google's snippet for that page, and the AI Overview above it, say the text comes two hours before the session ends; the page says after it starts.

The end time in that text is quoted in Eastern Time, at least in the screenshots people post. The r/verizon poster behind the thread on TravelPass counting days with no usage was told a session "will end on 4/3/26 at 8:21ET", and got that text at 08:23 local on 4 April. Convert before you switch the line back on.

AT&T's Day Pass page, dated 2 March 2026, runs the same clock and adds a cap: "You'll never pay more than 10 daily fees per line, per bill period for land or air travel." Per bill period, not per trip. One r/ATT family on a 15 day trip saw 12 charges across two cycles, and the roaming detail can post a month late.

What each carrier says starts a pass, in its own words

All four pages were read on 14 September 2026 unless a date is given.

Carrier and price	What starts a session, their words	Received texts	Wi-Fi calls
Verizon TravelPass, $12 a day, $6 in Canada and Mexico	"make or answer a phone call, send a text or use data", including background data once cellular data or data roaming is on	Not in the FAQ list; Verizon's Reddit account says receiving does not trigger	Not included; calls to a country other than the US billed at long distance rates, calls to the US free
AT&T International Day Pass, $12 a day, $6 for extra lines the same day, $20 at sea	"use data, send a text, or make or accept a phone call" on the plan page; "make or receive a call" in the legal terms	"rated as domestic and don't charge a daily fee"	A Wi-Fi call "to anywhere other than the U.S." bills a daily fee; calls to US numbers free
Spectrum Mobile Global Day Pass, $10 a day, $5 in Canada and Mexico	"starts once you place a call or use data abroad"; roaming is on by default	Not addressed on the support page	Not addressed on the support page
Xfinity Mobile Global Travel Pass, $10 a day	"only charged once you start the pass by using data in a covered location"; $0.30 per MB without it	Not addressed on the support page	Not addressed on the support page

Verizon's official account, replying on r/verizon in August 2026, wrote: "TravelPass can be triggered by making or receiving a call, sending a text message(receiving a text doesn't trigger), and using data. Using data includes background data like refreshing an app or an update even if you don't manually trigger these events." Note the drift from "answer" on the FAQ to "receiving" on Reddit. Verizon has not said whether a call that rings out to voicemail bills a day, and we will not pretend to know.

AT&T's three pages say "accept" once and "receive" twice, and agree on everything else. Its legal terms add two lines worth reading twice: "Apps on your device use data even when you may not be aware. Such usage may trigger the daily fees." and "To avoid unintended use of IDP, turn off cellular data roaming and WiFi calling in your device settings."

Why data roaming off was never enough

The Data Roaming switch stops that line using mobile data on a foreign network. It does not stop the line registering on that network for voice and SMS, which happens the moment the phone leaves airplane mode. That registration lets a bank code arrive, and it lets an answered call or a sent text open a $12 session. AT&T's settings article says turning off data roaming "prevents you from using data until you connect to Wi-Fi", and nothing on either AT&T page claims it stops voice or SMS.

A commenter on that August 2026 r/verizon thread put the mechanism in one line: "Disabling data roaming on iPhone does not disable voice roaming. (SMS also uses the voice network.)" A dual SIM iPhone is dual standby, so a call or text on the Verizon line arrives through Verizon's roaming partner either way. Apple's Dual SIM guide has no per line voice roaming switch, and warns of extra charges "if you send SMS/MMS attachments on the line that's not selected for cellular data."

⚠

About the setup we recommended before Our Verizon TravelPass cost post, our AT&T Day Pass post and our data roaming on or off guide describe a receive only setup: home line on, its data roaming off, travel eSIM for data. It keeps your number ringing and bank codes arriving, and it is also the setup in most of the billed threads. It costs a day the moment you answer a call, send a green bubble text or reply in a group chat with an Android user in it. The closest thing to a guarantee is the home line off, which is also what Verizon's own account recommends.

The six phantom triggers people hit with a travel eSIM installed

Every "I did everything right" case we read falls into one of these. Carriers have confirmed some; users inferred the rest.

A call you picked up. A spam call answered by reflex on the wrong line is a $12 day on both carriers, the one trigger every page agrees on. One r/verizon poster in September 2026 gets up to four spam calls a day and asked whether the unanswered ones count. Verizon's FAQ says "answer", its Reddit account says "receiving", and nobody at Verizon has reconciled the two.

A text you did not know you sent. When iMessage cannot deliver a blue bubble, the phone can resend it as a green SMS on the home line. AT&T told one r/ATT poster, line supposedly off and data on a Ubigi eSIM, that "he sent SMS/MMS from his phone line", and that ended the $156 dispute. A commenter on another r/ATT thread who has never been charged turns Settings, Messages, Send as SMS off before flying.

A group chat. Any group with a non iPhone member goes out as MMS, and MMS rides the home line. A traveller on r/travel with a Spectrum line kept getting Global Day Pass texts despite Airalo for data, roaming off and switching off. The answer came in three words: "it's the group chats".

Background data in kilobytes. Verizon's FAQ lists app refresh, sync and updates as session starters once cellular data or data roaming is on for that line. A commenter on r/ATT who says they work in billing wrote: "I do see many accounts that get charged for background data. Literally kilobytes per day." One r/verizon poster in July 2026 was billed after waking the Verizon line for about three minutes on Wi-Fi with data off, and blames visual voicemail. No carrier has confirmed that cause.

Allow Cellular Data Switching. Apple's page on the feature says "Your data line switches automatically for the duration of your call." Leave it on and a call on the home line can pull data through the home line while you talk.

A Wi-Fi call to a number outside the US. AT&T's Day Pass page: "You'll be charged a daily fee when you make a Wi-Fi call to anywhere other than the U.S." Verizon's FAQ: "Wi-Fi calling to a country other than the US is charged international long distance rates." Ringing the hotel from the lounge is enough.

No carrier page says that merely connecting to a foreign tower bills the day. Carriers bill on an event, and the phone that only "connected" was billed because one of the six followed within seconds. A Rick Steves forum poster watched it happen "as SOON as the phone was switched out of airplane mode", and what worked for her was the Verizon plan switched off while out.

The iPhone settings that actually stop it

This order keeps the home line from registering abroad while still letting you wake it on purpose. Our dual SIM setup guide covers the basic two line configuration; this list adds what it does not.

At home on Wi-Fi: install the travel eSIM and leave its Turn On This Line switch off. If you want Wi-Fi Calling on a Verizon line abroad, enable it now; on iOS Verizon says it "can't be activated after you leave the country".
Settings, Cellular, tap the home line, Cellular Data Options, Data Roaming off. On its own this covers data only.
Settings, Cellular, Cellular Data, choose the travel line, and turn Allow Cellular Data Switching off on the same screen.
Settings, Messages, Send as SMS off. A community recipe, not a carrier instruction, from the r/ATT commenter who reports zero charges with it.
Airplane mode on for the flight. After landing and before airplane mode comes off, tap the home line under Settings, Cellular and switch Turn On This Line off. Verizon's knowledge base notes this switch only appears once a second SIM is installed.
Airplane mode off, travel line on, Data Roaming on for the travel line only. A travel eSIM is roaming everywhere by design.
When you need the home number, get on solid Wi-Fi, turn the line on, wait for the code, turn it off. The July 2026 report of a charge after three minutes is the reason to be quick.

ℹ

Read the session text in your own time zone If a session did start, Verizon quotes the end time in Eastern Time. Work out the local equivalent and keep the line off until then, plus a margin, or you risk a fresh 24 hours.

On a Pixel, Google's page puts the line switch at Settings, Network and internet, SIMs, tap the SIM, Use this SIM off; the same screen holds Your primary SIMs and Automatic data switching, which should be off. On a Samsung Galaxy it is Settings, Connections, SIM manager, with a switch per SIM and Data Roaming Access under Mobile networks. When you want silence, switch the home SIM off.

Keeping 2FA texts without paying for a day

Nobody wants TravelPass; they want the six digit code from the bank on Tuesday. The options, ranked by how far you can trust them.

Option	Verizon	AT&T	What can still bill
Home line off, woken on Wi-Fi for the code	Received texts do not trigger, per Verizon's Reddit account	Received texts "rated as domestic", per the Day Pass page	Background data while the line is awake; one report of a charge after three minutes
Home line on, receive only	Texts free, calls ring	Texts free, calls ring	Any answered call, sent text, group MMS or Wi-Fi call abroad starts a $12 day
Remove the pass, pay as you go	Verizon's KB says disabling TravelPass "blocks international usage"; users report $0.05 per received text and $2.05 per MB instead	Remove IDP at att.com/signin or 833.669.2516; then $2.05 per MB, $4 a minute, $1 per sent text	One background megabyte costs more than a Europe eSIM day
Plan swap for the trip	Unlimited Ultimate includes international data, talk and text and cannot take TravelPass; users say device credits survive from Plus or Welcome	No equivalent published	Verizon's page gives no data figure; the 15 GB users quote is their report

The pay as you go row comes up in every thread as the clever answer. Verizon's knowledge base says "disabling TravelPass blocks international usage", while r/verizon users who removed it report Pay As You Go rates instead. Both cannot be true for every account, so ask in chat what your line will do before you touch it. One r/ATT poster who kept the line on for incoming calls and texts passed $1,000 in charges; commenters suspected the line had lost IDP and was on pay per use.

Our own number plans do not solve this either. The Europe number plan gives a European mobile number with 20 GB, unlimited calls, 200 SMS and 30 days for $24.99, and the issuing country varies at activation. It cannot receive a text sent to your US number, and the plan page says it does not replace your home SIM for bank codes or verification texts.

Wi-Fi Calling and iMessage: what stays free and what gets billed

One r/verizon thread has a commenter saying Wi-Fi Calling "does not count as roaming" and another calling it "normal cellular calls". The carrier pages settle it. Verizon's Wi-Fi Calling FAQ says "Calling back to the US is free", and the TravelPass FAQ bills calls to any other country at long distance rates. AT&T's page dated 16 April 2026 makes Wi-Fi calls to US numbers free, and the Day Pass page starts a daily fee for a Wi-Fi call anywhere else. The destination decides, not the Wi-Fi.

iMessage is murkier. Apple's page dated 13 May 2026 says "you need an active SIM or eSIM associated with that number", and does not say what happens when you toggle that line off. One Apple community reply from 2025 says the number drops out of iMessage and friends must message your Apple ID email; another from July 2026 says it kept working "for a certain amount of time". Plan for the number to lapse, tell the people who matter which email reaches you, and keep WhatsApp on the travel eSIM.

You were charged anyway: read the usage and dispute a phantom day

Start with the itemised usage, not the total. You are looking for the event that opened each session: a sent SMS or MMS, a call with a duration, or a data amount. In a June 2025 Xfinity forum case, two lines with the eSIM off and roaming off were billed $10 a day each for "0.01MB" of usage, $560 in total. If your record shows three sent texts against twelve charges, you are in the r/ATT family's pattern, where the supervisor refused to waive because usage existed. As one commenter there put it, agents "should be making adjustments when there is no usage", but not when data or calls show.

Verizon's general support is 800-922-0204, and from abroad +1-908-559-4899, which Verizon says may carry toll charges. Reddit and Rick Steves forum users also cite 800-711-8300 as the international team, which we could not find on a Verizon page today. For AT&T, 833.669.2516 handles the Day Pass, and from abroad +1.314.925.6925 is free from an AT&T phone. Give the dates, the state of the line on each date, what the itemised usage shows, and ask which event started each session.

The documented outcomes are not generous, and we will not promise you one. AT&T credited $50 of $156 in one case and $150 of more than $1,000 in another. Xfinity refunded the $560 only after the executive team got involved. Verizon removed days via chat for the poster whose line was completely off, and not for others. Then close the door for the rest of the trip: turn the home line off, and treat the Reddit workarounds as what they are. Manual network selection to a network Verizon does not partner with only works after landing, and not everywhere. A SIM PIN to block registration still got one poster charged. Another reported in September 2026 that the international block set in the My Verizon app removed itself after about 24 hours, and Verizon's pages read today do not document such a block at all.

⚠

Write down the state of the line each day A screenshot of Settings, Cellular showing the home line off, with the clock visible, is the evidence the threads with credits had and the others did not. Take it on landing and again each time you wake the line for a code.

When the day pass is the right call, and when a Europe eSIM is

A day pass is fair for a weekend. Land Friday night, fly home Sunday, take work calls on your own number, change nothing: $24 or $36 is a reasonable price for not thinking about any of the above. Verizon's $10 a month 3 TravelPass Days perk, on Simplicity, Unlimited Plus and Unlimited Welcome and banked for up to 12 months, makes that cheaper, with the same trigger wording. T-Mobile customers can skip this post. Its roaming page, read on 14 September 2026, has no day pass, and our T-Mobile roaming post covers what its 256Kbps fallback feels like.

For anything longer the arithmetic goes one way. Ten billed days on either carrier is $120, on a line you cannot safely answer. Our Europe eSIM plans cover 34 countries on one profile from $1.99 for 1 GB over 7 days, up to 50 GB for 30 days at $33.99. Unlimited Europe plans start at $1.29 for one day, with 1 GB per day at full speed then up to 1 Mbps for the rest of that day, and they run on a different 35 country area that excludes France and Turkey. For those two, pick a fixed plan or the country page. Every plan is data only, no number and no SMS. The eSIM carries the trip; the home line stays off and gets woken on Wi-Fi when the bank asks.

Quick answers

How do I avoid getting charged for my Verizon TravelPass with an eSIM installed?

Turn the Verizon line off: Settings, Cellular, tap the line, Turn On This Line off, offered once a second SIM is installed. Data roaming off alone stops data only. An answered call, a sent text, a group MMS or a Wi-Fi call to a country other than the US still starts a $12 session. Received texts do not.

Will I still be charged if I turn off data roaming?

You can be. Data roaming off stops mobile data on that line and nothing else. The line still registers on the foreign network for voice and SMS, so an answered call, a sent or fallback SMS, a group MMS or a Wi-Fi call abroad can each bill a day. Documented cases were billed with roaming off and switching off.

How do I use an eSIM to avoid AT&T Day Pass charges?

Install the travel eSIM, set it as the cellular data line, turn Allow Cellular Data Switching off and turn Data Roaming off on the AT&T line. Then either turn the AT&T line off or remove the Day Pass at att.com/signin or 833.669.2516, knowing pay per use is $2.05 per MB and $4 a minute. Received texts are free either way.

Does receiving a text trigger TravelPass or the AT&T Day Pass?

No, according to both carriers. AT&T's Day Pass page says received texts are rated as domestic and do not charge a daily fee, and Verizon's official Reddit account says receiving a text does not trigger TravelPass. Sending one does on both, including an iMessage that falls back to SMS. Unanswered incoming calls are the grey area neither carrier has settled.

How do I avoid the AT&T International Day Pass entirely?

Three ways. Turn the AT&T line off and run data on a travel eSIM. Keep the phone in airplane mode with Wi-Fi on and Wi-Fi Calling off, which is AT&T's own published advice. Or remove the Day Pass and accept pay per use rates. Turning off data roaming alone does not stop sent texts, answered calls or Wi-Fi calls to numbers outside the US.

Is there a way to bypass roaming charges on a day pass plan?

Not while the home line is registered abroad. The options are the home line off with a travel eSIM for data, airplane mode with Wi-Fi, or a plan that includes international use, such as Verizon's Unlimited Ultimate. Manual network selection, SIM PIN tricks and the in app international block are community workarounds, and one of them still got charged.

How long does a TravelPass day last?

24 hours from the first qualifying use, not a calendar day. Verizon texts you two hours after the session starts with the time it ends, and users' screenshots show that time in Eastern Time. Using the line after that time starts a new session, so convert the end time to local before you turn the line back on.

Why did TravelPass count a day when my Verizon line was off?

No carrier has published a cause. The documented patterns are a text that fell back to SMS, a group MMS, kilobytes of background or voicemail data when the line was briefly awake, and usage timestamps in Eastern Time crossing a session boundary. Ask Verizon for the itemised event that opened the session; days with no logged usage have been removed in chat.
