Will My US Number Get 2FA and Bank Texts in Japan? AT&T, Verizon, T-Mobile (2026)
Often yes, but not always, and it depends on your carrier, your bank and your phone settings. Receiving a text usually costs nothing extra: on AT&T, received texts are rated as domestic and do not trigger the $12 International Day Pass fee, and T-Mobile postpaid plans include unlimited texting in Japan. On Verizon, receiving a text is not listed as a TravelPass trigger, but a line with no international plan pays $0.05 per received text. Delivery is a separate question. T-Mobile's support page says that while overseas, you will not receive short code messages, and bank codes often come from 5- or 6-digit short codes (Chase, for example), so T-Mobile customers may not get those bank texts in Japan and should switch their bank and email to app approval or an authenticator app before the trip. Any carrier also needs international roaming working on your line (or Wi-Fi Calling connected), and some banks won't text Google Voice numbers. This guide covers AT&T, Verizon and T-Mobile postpaid consumer plans; prepaid, business and other providers have their own rules.
Verizon: TravelPass ($12 / day) starts when you make or receive a call, send a text or use data. Without TravelPass: $0.05 per received text, $0.50 per sent text.
T-Mobile (postpaid): texts in Japan are unlimited on all listed plans, but T-Mobile says you will not receive short code messages while overseas. Calls cost $0.50/minute.
Wi-Fi Calling: AT&T, Verizon and T-Mobile say Wi-Fi calls to US numbers are free. Verizon iPhones can only switch Wi-Fi Calling on while connected to Verizon in the US.
Best backup (essential on T-Mobile): switch your bank and email to app approval or an authenticator app before the trip, and save backup codes.

1. What each US carrier charges for texts in Japan
| Carrier | Receiving a text (2FA code) | What starts a charge |
|---|---|---|
| AT&T with International Day Pass | Rated as domestic. Does not trigger the daily fee | Using data, making or receiving a call, or sending a text: $12 for 24 hours ($6 for each extra line charged the same US calendar day). Max 10 daily fees per line per bill cycle |
| Verizon with TravelPass | Not listed as a TravelPass trigger | Making or receiving a call, sending texts or using data: $12 per line per day (5GB high-speed, then 3G speed) |
| Verizon with no international plan (pay as you go) | $0.05 per received text ($0.25 per received picture message) | $0.50 per sent text, $2.05/MB data |
| Verizon Unlimited Ultimate | Included | International data, talk and text are included (TravelPass can't be added) |
| T-Mobile postpaid (Better Value, Experience Beyond/More, Go5G Next/Plus/Go5G, Magenta, One, MAX, One Plus, and "other T-Mobile plans") | Text: Unlimited in Japan | Calls $0.50/minute. Data is included at different speeds by plan (other plans: $1.00/MB) |
- AT&T Day Pass is added automatically. If you have no other international feature and use your phone in Japan, AT&T adds the Day Pass and texts you; you can opt out from that text. The "calendar day" for the $6 extra-line price follows your US time zone, not Japan's.
- Verizon background data can start a TravelPass day. Verizon says app refreshes, email syncing and software updates can start a session once cellular data or data roaming is on, and that to use TravelPass you must turn on cellular data or data roaming.
- Verizon dual-number phones: if your phone has 2 Verizon numbers and you use both abroad, each line is charged under its own international plan.
- T-Mobile with no domestic texting plan: texts received while roaming come out of your domestic text allotment. T-Mobile says it has no international data roaming for prepaid; prepaid talk and text rates are on a separate page we did not check for this article.
- T-Mobile and short codes: T-Mobile's self-service short codes page says, "While overseas, you will not receive short code messages." If your bank sends codes from a short code (Chase lists 301528, 242733 and 60969, for example), plan on app approval instead.
- Codes by phone call cost more on T-Mobile. If a bank calls you with a code instead of texting, answering costs $0.50/minute, and even an unanswered call that goes to voicemail is charged one minute if your phone is on.

2. Can I turn off data roaming and still get the code?
Usually, yes. Turning off Data Roaming stops your US line from using data abroad; it does not switch the line off. AT&T says that with data roaming off "you should be able to make and receive phone calls and text messages," and Verizon says that "on most devices" you can still make or receive calls and send or receive messages with data services turned off. Your phone still needs coverage from a Japanese partner network, and short-code texts on T-Mobile are the exception above.
- AT&T: receiving texts does not start the $12 fee. Sending a text, making or answering a call, or using data does.
- Verizon: turning off data roaming prevents roaming data use, but Verizon still lists making or answering a call and sending texts as things that start a TravelPass day. Without TravelPass on the line, each received text is $0.05.
- T-Mobile: received texts are already included, so data roaming on or off only changes your data use.
- Airplane mode with Wi-Fi on turns off the cellular connection. Texts can then arrive only through Wi-Fi Calling (next section).

3. Wi-Fi Calling: texts over hotel Wi-Fi
Wi-Fi Calling lets your phone send and receive your normal US calls and texts over Wi-Fi instead of a cellular network. Capital One's travel page says that with Wi-Fi Calling on, you can receive text verification codes on Wi-Fi even in airplane mode.
| Carrier | From Japan over Wi-Fi Calling |
|---|---|
| AT&T | Calls to US numbers: no additional charge. Texts sent or received count the same as regular texts on your plan. Calls to non-US numbers (including Japanese numbers) cost extra, but AT&T's pages differ on how: its Day Pass guide says a Wi-Fi call to anywhere other than the US triggers the daily fee, while its "Call and text internationally" page (updated August 26, 2026) bills them as international long distance even with an international plan. Either way, call only US numbers over Wi-Fi |
| Verizon | Calling back to the US is free. Calls to other countries are charged at international long distance rates. Wi-Fi Calling isn't included with TravelPass. iPhone: Wi-Fi Calling must be turned on while connected to Verizon in the US; it can't be activated after you leave |
| T-Mobile | All Wi-Fi calls to US numbers are free. Wi-Fi calls to international numbers depend on your roaming option |
Two setups: pick one
- Setup A, US line on cellular (easiest): keep your US line on with data roaming off. Texts arrive over the Japanese partner network wherever you have signal. Wi-Fi Calling can stay on as a backup indoors, but don't place calls to Japanese or other non-US numbers from the US line.
- Setup B, airplane mode + Wi-Fi Calling: no cellular use at all on the US line; codes arrive only while you are on Wi-Fi. AT&T's Day Pass guide suggests turning Wi-Fi Calling off only because Wi-Fi calls to non-US numbers cost extra. If you only receive texts and call US numbers, leaving it on doesn't start that charge.
Test it before you fly: at home, turn on Wi-Fi Calling and enter your US emergency address when the phone asks (AT&T and Verizon require one for 911 routing). Then switch to airplane mode, turn Wi-Fi back on, check that your phone shows Wi-Fi Calling in the status bar, and ask your bank to send you a sign-in code. A test call only proves calling works; the code test proves your bank's texts get through.

4. Travel eSIM for data, US line for texts
Many travel eSIMs are data-only, so check your plan. You can keep your US SIM or eSIM turned on as a second line just for calls and texts. Compare eSIM, pocket Wi-Fi and US roaming prices in our Japan eSIM vs pocket Wi-Fi vs US roaming guide.
First check your phone is unlocked. Apple says an iPhone locked to a carrier can't use another carrier's eSIM. Go to Settings > General > About: if it shows "No SIM Restrictions" next to Carrier Lock, you're fine. Using two active eSIM lines at once also needs a model that supports Dual SIM. On Android, check your carrier and phone maker.
iPhone
- Install the travel eSIM by following your eSIM provider's instructions (check whether its validity starts at install or at first connection).
- Settings > Cellular > Cellular Data: choose the travel eSIM.
- Keep your US line turned on ("Turn On This Line"). Apple says that if you keep both lines on, your primary line keeps working, though you might still incur roaming fees from it.
- Leave Allow Cellular Data Switching off, and keep Data Roaming off on the US line, so your US line doesn't use data.
- Apple notes that if data roaming is on for the data line, Visual Voicemail and MMS (picture messages) don't work on the voice-only line. Plain SMS codes are not affected by this note.
Android (Pixel steps; other brands use similar names)
- Settings > Network & internet > SIMs.
- Under "Your primary SIMs": Mobile data = travel eSIM; Calls and Texts = your US SIM.
- On the US SIM, keep Roaming off unless you want to use your carrier's data plan.

5. Google Voice: useful, with limits
- Some banks won't text a Google Voice number at all. Google itself says some websites, such as banks or subscription services, won't send texts to Google Voice numbers, and you may need to use your mobile carrier number.
- Other texts do reach Voice from anywhere in the world, over Wi-Fi or mobile data.
- You can't send texts to 5- or 6-digit "short code" numbers. Many bank codes come from short codes (Chase lists its one-time codes as 301528, 242733 and 60969), so you can't reply to them from Voice.
- Paid Voice subscriptions (Google Workspace) offer text messaging only in the US.
- Whether your bank will send codes to a Google Voice number is the bank's rule. Don't move your bank's 2FA to a Voice number right before a trip without testing it.

6. Don't depend on texts: bank app approval and backup codes
- Capital One: in the app, Profile > Sign in & security > Mobile app verification. Capital One says this lets you verify your identity over Wi-Fi if you can't receive SMS while traveling. It also says you don't need to notify it before you travel.
- Chase: for unusual sign-ins, Chase says it uses mobile app notifications or a one-time code. Install and sign in to the Chase Mobile app before you go.
- Google account: create a set of 10 backup codes; each works once. Google suggests keeping a printed copy where you keep your passport. An authenticator app also works without a phone signal.
- Wells Fargo: its Advanced Access FAQ says getting your code by push notification in the Wells Fargo Mobile app "may be available" while traveling internationally, and you can call toll-free from most countries.
- For any other bank or app: look in its security settings for "app approval", "push notification" or "authenticator", and switch to it at home, while you can still receive texts.
The code didn't arrive: what to check
- Does your US line have signal? If it shows no service, the line may not be registered on a Japanese network. Turn it off and on, or connect to Wi-Fi and use Wi-Fi Calling.
- On Wi-Fi: does the phone show Wi-Fi Calling? If not, codes won't come over Wi-Fi. Verizon iPhones can't turn it on outside the US.
- Other texts arrive but the bank's don't? The bank's sender may be a short code (T-Mobile: not received overseas) or may not deliver abroad. Choose app approval, a phone call or email if the bank offers it, or call the bank's international number (for example, Capital One lists 1-804-934-2001).
Receiving a code doesn't guarantee a card payment goes through, and the bank may not offer a text at all. If a card is declined in Japan, check the bank app for a fraud alert and contact the bank if it continues. More on that: why US cards get declined on smartEX (3D Secure) and US credit and debit cards and ATMs in Japan.

7. Before-you-fly checklist
- Open your carrier app and check which international feature is on your line (AT&T Day Pass, Verizon TravelPass or Unlimited Ultimate, your T-Mobile plan name).
- Turn on Wi-Fi Calling and set your emergency address in the US (required for Verizon iPhones).
- Install your travel eSIM, set it as the data line, keep the US line on for calls and texts.
- Turn on app approval or an authenticator for your bank, card and email; save Google backup codes.
- Confirm your phone number and email are current in each bank app, and test a real bank code in airplane mode + Wi-Fi.
- On an iPhone, check Settings > General > About > Carrier Lock shows "No SIM Restrictions" before buying an eSIM.
- In Japan: keep data roaming off on the US line and don't reply to code texts. Incoming calls can cost money even unanswered: on T-Mobile, a call that goes to voicemail while your phone is on is charged one minute ($0.50 in Japan).
FAQ
I'm on T-Mobile. Will my bank code arrive?
Maybe not. T-Mobile says you will not receive short code messages while overseas. Switch the bank to app approval or an authenticator before you go.
Will a 2FA text start my AT&T $12 Day Pass?
No. AT&T's terms say received texts are rated as domestic and do not trigger a daily fee. Sending a text, a call (made or received) or any data use does.
Does Verizon charge me to receive a code?
On TravelPass, receiving a text is not in Verizon's list of things that start a session. On pay as you go, it's $0.05 per received text. Unlimited Ultimate includes international texts.
My phone is in airplane mode. Can I still get codes?
Only over Wi-Fi Calling, with Wi-Fi turned on. Set Wi-Fi Calling up before you leave the US.
Will iMessage codes work?
iMessage runs over the internet, so it works on any Wi-Fi or eSIM data. Codes sent by text message (SMS) need your US line or Wi-Fi Calling. AT&T's unlimited text in Day Pass covers SMS and MMS only, not iMessage.
