Thailand SIM card, your US carrier or an eSIM? What a trip to Thailand costs each way
In short
A day on an AT&T or Verizon postpaid pass costs $12 in Thailand. Two weeks of Verizon TravelPass come to $168 for one phone (our arithmetic, checked on October 29, 2026). Data there is cheap: our October 29, 2026 check of travel-eSIM sellers put Thailand’s 30-day median at $6 for 3GB and $11 for 10GB.

eSIM for Thailand from $3.99 — see plans
This site is not affiliated with any carrier named on this page; we sell eSIMs. How we compare
You may not need an eSIM. Thailand data already comes with Google Fi Unlimited Premium, US Mobile Unlimited Premium, AT&T Elite 2.0 and T-Mobile’s Experience Beyond and More. Total Wireless (MAX 5G, MAX 5G BYO, ALL ACCESS), Spectrum Unlimited Plus and Xfinity’s Plus and Select lines carry it too.
Inside that allowance you need no Thailand SIM card at all: no extra data charge, and you keep your own number. Verizon Unlimited Ultimate is the open case: Verizon gives it 210+ countries and destinations but no list, so ask Verizon whether Thailand is one.
Two bill traps. Data with no pass costs $2.05 per MB in Thailand on AT&T (rates) and on Verizon (rates). One 3 MB photo upload then costs $6.15 (our arithmetic).
Verizon starts a $12 TravelPass day at your first use in Thailand. Background data counts, such as apps refreshing or email syncing, and so does one call or text (TravelPass FAQs). With no pass, a Verizon call there is $1.79 a minute.

Does your US phone work in Thailand? Carrier by carrier
Yes on every US carrier that publishes a country list: Thailand is on all of them, Boost Mobile’s included (checked on October 29, 2026). A day there costs $10 on Visible, Cricket, Xfinity and Spectrum passes, and $12 on AT&T and Verizon.
| Option | Price | What you need | Weak point |
|---|---|---|---|
| Roaming with your US carrier | May be included on some postpaid or prepaid plans of 5 of 9 US carriers otherwise $10.00 to $100.00 a day or pass from about $2.50 per GB | Data roaming on; with some carriers a pass added before you fly | Paid passes cost more per GB than the eSIM |
| Pocket Wi-Fi router | Not verified | Collect it, keep it charged and return it | One connection for the group, only while you stay together |
| Local SIM bought on arrival | Not verified | A free SIM slot and a shop after landing | An iPhone 14 or later bought in the US works with eSIM only |
| Travel eSIM from this site | from $3.99 by card; from $0.90 per GB | An eSIM phone that is not locked to your carrier | Data only: no calls or texts on your US number |
Roaming prices as published by US carriers, before taxes and fees, checked on October 29, 2026; price per GB is our derivation (price ÷ GB). eSIM prices are in US dollars: your card is charged exactly that amount. This site is not affiliated with these carriers; we sell eSIMs.
Three give you no list to read: Verizon Prepaid and Mint keep theirs in a search box, and Straight Talk publishes none. What really differs is how each one bills you in Thailand.

Spectrum stands apart on pay-per-use: its $0.03/MB rate in Thailand sits far below the $2.05 per MB that AT&T and Verizon bill.

eSIM for Thailand: selected plans
The entry plan, our pick and a bigger one. “Our pick” is a mid-size plan chosen by us, not a sales ranking.
You are charged exactly the price shown, in US dollars. The seller is a company registered in the United States, so this is a payment to a US business — how card payment works. It appears on your statement as JET SHARING. You pay on the secure Stripe checkout page, by card, or Apple Pay or Google Pay if Stripe shows them on your device.
What it costs per day
The plan price is what you pay for the trip; a day is that price over the plan’s own days, so a longer plan costs less a day only if you use those days. Pick by your trip length first.
How we compared the options for Thailand
For one phone, two weeks of Verizon TravelPass in Thailand run $168, and the Monthly Plan $100 (our arithmetic, checked on October 29, 2026). AT&T’s Day Pass lands between $120 and $168, by billing cycle; our Thailand plan with 10GB for 30 days is $10.99, data only.
Our method, dated October 29, 2026, puts three routes next to each other: a carrier pass, data included in your plan, and a travel eSIM. We scored each on the price for 7, 10 and 14 days, the data you get, and the phone it needs. A Thailand SIM card, with no checked terms or prices, is weighed on the phone side only, in the next section.
Searching “best eSIM for Thailand”? This dated method is our answer, and it names or ranks no seller.
We took prices from 11 travel-eSIM sellers from a US IP that day. For Thailand, their median was $6 for 3GB over 30 days and $11 for 10GB. Mexico sat at $9.50 and $24 in the same check, and Canada at $9 and $23.
Against that, 14 TravelPass days cost about 15 times the $11 median (our arithmetic, $168 against $11). The pass pays for keeping your own number, not for gigabytes; our methodology sets the rules for each basket.
Every figure in the table is our arithmetic for one phone on a land trip; allowances are in the carrier table above.
| Option for one phone in Thailand | 7 days | 10 days | 14 days |
|---|---|---|---|
| Verizon TravelPass, postpaid, $12 a day | $84 | $120 | $168 |
| Verizon International Monthly Plan, $100 | $100 | $100 | $100 |
| AT&T International Day Pass, postpaid, $12 a day | $84 | $120 | $120 to $168 |
| AT&T Prepaid Travel Add-On, $40 per 7 days | $40 | $80 | $80 |
| T-Mobile Essentials with an International Pass | $50, 10-day Pass | $50 | $75, 30-day Pass |
| Cricket Passport, $10 a day | $70 | $100 | $100 to $140 |
| Visible, Xfinity or Spectrum day pass, $10 | $70 | $100 | $140 |
| Data already in your plan (“In the plan” rows above) | $0 extra | $0 extra | $0 extra |
| Our Thailand plan, 10GB for 30 days, data only | $10.99 | $10.99 | $10.99 |
| Our Thailand plan, 20GB for 30 days, data only | $17.99 | $17.99 | $17.99 |
| Our plan, Unlimited — 5 GB/day at full speed, then reduced to 1 Mbps, data only | $20.99 for 7 days | $27.99 for 10 days | $38.99 for 15 days |
AT&T’s range is a billing rule. Its cruise page prices land use at “$12 per day for 10 days within a single billing cycle” (checked on October 29, 2026, AT&T).
Inside one cycle, 14 days are billed as 10, or $120. A trip that runs into the next cycle can be billed all 14, or $168 (our arithmetic).
Verizon prices the Monthly Plan at “$100/mo per line” and calls it “Perfect for trips of 9 days or more” (Verizon Monthly Plan). Nine TravelPass days already cost $108, and over two weeks the Monthly Plan comes in $68 under daily passes (our arithmetic).
On T-Mobile Essentials, Thailand data needs a Pass. The $50 10-day Pass covers a week, and the $75 30-day Pass two weeks (checked on October 29, 2026, T-Mobile Passes).
Cricket’s daily pass gets cheaper on a long trip. After 10 days in a row within a 30-day period, Cricket adds “up to an additional 20 days of usage at no extra cost” (Cricket). Fourteen straight days then cost $100, and $140 if the free days don’t apply (our arithmetic).
If Thailand is already in your plan, the eSIM does not win: $0 extra inside the allowance. On Google Fi, Thailand data comes out of the same monthly high-speed allowance you use at home (Google Fi).
Our 10GB plan works out to about 0.71GB for each of 14 days, the 20GB plan to about 1.43GB (our arithmetic). The 7-day plan, Unlimited — 5 GB/day at full speed, then reduced to 1 Mbps, is $20.99, data only. Seven full-speed days hold up to 35GB (our arithmetic).
With a carrier pass, your calls and texts stay on your US number. Ours is a data-only plan. The plan doesn’t state a hotspot rule — check the plan page.
Roaming or eSIM runs the math for your own dates.
A Thai tourist SIM or a travel eSIM?
On a US-bought iPhone 14 or later, a Thailand SIM card for tourists is off the table. Apple’s support page says an iPhone 14 or later bought in the US activates with an eSIM only (checked on October 29, 2026, Apple).
On a phone that still has a SIM tray, a tourist SIM from a Thai carrier such as 
AIS remains an option. We hold no checked terms or prices for Thai tourist SIMs, so this page prices none of them and ranks none.
We sell no physical Thailand SIM card. Do iPhones have SIM cards? lists the models that still have a tray.
What our Thailand plan covers
Our Thailand plan lists dtac (5G) as its network, but its notes say “Operates on the True & AIS networks in Thailand.” The two disagree, so we promise neither network; check coverage where you will stay (plan details as of October 29, 2026).
The notes also say it “Covers the mainland and islands, including Phuket, Koh Samui, Krabi and Phi Phi.” It is data only, your US number stays on your main line, and its validity runs from the first connection in Thailand.
How much data do I need? sizes the plan for maps, video and calls.
Before you go: unlocked phone and your US number
Apple’s rule for using a second carrier abroad is plain: “your iPhone cannot be locked to a carrier” (checked on October 29, 2026, Apple). Put the eSIM on over home Wi-Fi before the flight to Bangkok or Phuket, following how to install an eSIM.
Apple also warns that with both lines on, your home eSIM could still add roaming fees (Apple). Switch data roaming off on the US line (data roaming), though a call or text there can still start a $12 AT&T or Verizon day. For 2FA codes and texts, see Dual SIM and keep your US number.
The U.S. Department of State rates Thailand Level 1: “Exercise Normal Precautions” (updated July 6, 2026, travel.state.gov).
Check before you fly
What if the eSIM doesn’t work when you land in Thailand?
Check four settings, in this order, before you write to us.
The first is the line for cellular data. In the phone’s SIM settings, pick the travel line for cellular data; your US line stays on for calls and texts, with its cellular data off.
The second is data roaming, for the eSIM line only. The eSIM is a foreign profile, so the phone treats Thailand as roaming for it.
The third is the APN. On this plan it sets itself, so leave it alone; you don’t need to type one.
The fourth is a restart. Restart the phone or switch Airplane Mode on and off, and let it find dtac; this can take a few minutes after you leave the plane.
Still no data? Write to us on WhatsApp or at support@esimworld.us with your order number, or go through the no-signal checklist. Do not delete the eSIM to “try again”: a deleted profile usually cannot be installed twice from the same code. If the eSIM doesn't work and it isn't your phone's fault, we refund the payment whether or not it was installed.
What I’d choose (and when NOT to buy the eSIM)
For a week of maps, rides and messaging I’d take 1 GB for 7 days, $3.99. For two weeks or more, with photos and social media, I’d go for 5 GB for 30 days, $7.99. If you video-call and stream every day, take the unlimited plan for 7 days, $20.99, with 5 GB a day at full speed, then reduced to 1 Mbps.
I would not recommend the eSIM in three cases. If your US plan already includes Thailand and its limit is enough for you, roaming costs you nothing extra and keeps your number (compare the carriers). If your phone has no eSIM or is locked to your carrier, it cannot take the plan: check if your phone is unlocked. And if your group travels together all day and shares one connection, a pocket Wi-Fi can cover everyone.
Frequently asked questions
Is an AIS tourist SIM or a travel eSIM better?
Only an eSIM, on a US iPhone 14 or later: Apple says those models activate by eSIM only (checked on October 29, 2026, Apple). On an older phone with a tray, we can’t rank the two, because we hold no checked AIS terms or prices. Weigh what AIS quotes you against the tables above.
How much data do I need for 2 weeks in Thailand?
As much as your phone uses at home in two weeks; its cellular usage screen shows the figure. Under 10GB, our 10GB plan for 30 days covers the trip; up to 20GB, the 20GB plan does. Video calls and tethering use far more than maps and messaging.
Does a Thailand eSIM work on a US iPhone?
Yes, on an unlocked iPhone that supports eSIM, and a US iPhone 14 or later takes nothing else. Add the plan over home Wi-Fi before the flight to Bangkok. Our plan’s days begin at the first connection in Thailand, so installing early costs you no days.
