Booking a month abroad means the data question lands late. Plans that add up country by country, a pass that runs out mid-trip, a roaming bill waiting at home.
Lost luggage barely rattles Atlas, our small globe with a massive passport. A surprise data bill is another story. Sticking with your carrier’s pass feels like the safe move, but for 30 days one flat-priced eSIM costs less.
Which costs less for 30 days: T-Mobile International Pass or an unlimited eSIM?
The unlimited eSIM costs less. Maya’s 30-day plan is USD 49.99 for unlimited data in 165+ countries, against $75 for 30 GB on T-Mobile’s 30 Day Pass (t-mobile.com, International Pass page, captured October 9, 2026).
That USD 49.99 works out to USD 1.67 per day. The data comes with a daily high-speed allowance that resets every 24 hours. Every plan is a one-time purchase that ends when its days end, and the same eSIM and price apply in every country. Jane B. wrote in a September 2026 Trustpilot review about what that flat price did for the budget: “Now I used Maya eSIMs and know exactly what I’m spending and get unlimited data.”
Maya has no control over your home carrier’s plan, so the T-Mobile figure above is theirs, read from their page. The Maya figure is ours.
What does T-Mobile’s 30-day International Pass include, and who can buy it?
Eligibility depends on a postpaid plan tier, so some travelers cannot buy the pass at all. For those who can, the 30 Day Pass is $75 for 30 GB, about 1 GB a day (t-mobile.com, 2026).
T-Mobile’s page says: “All International Passes comes with free calls and high-speed data you can use as a mobile hotspot.” Its own FAQ adds that calling from the U.S. to other countries is not discounted with a pass.
So a month on the pass comes with a gigabyte ceiling and a plan-tier check before you start. Our unlimited plan has a daily high-speed allowance that resets every 24 hours, and the eSIM works alongside the SIM you already carry. For a nomad or a business traveler working all day on the phone, the 1 GB-a-day line is the one to price against.
What does a month of data abroad cost on your home carrier’s own roaming pass?
A month on carrier passes runs $75 for 30 GB on T-Mobile’s 30 Day Pass, or $360 on the daily passes from Verizon and AT&T for 30 days of daily use. Maya’s 30-day plan is USD 49.99 for unlimited data with a daily high-speed allowance.
The daily passes add up fast. Verizon’s TravelPass is $12 per day in 210+ countries and destinations, so 30 × $12 = $360 (verizon.com, TravelPass page, captured October 9, 2026). AT&T’s International Day Pass is $12 per day on land for the first line, the same $360 over 30 days (att.com, International Day Pass page, captured October 9, 2026). At sea, or on land and at sea on the same day, AT&T’s pass is $20 per day, or 30 × $20 = $600 (att.com, 2026).
T-Mobile’s shorter passes are $10 for 2 GB for a day and $50 for 15 GB for 10 days (t-mobile.com, 2026).
Our eSIM data plans are meant to replace your carrier’s roaming plan. When the eSIM is installed correctly, your carrier typically won’t charge extra roaming fees. Contact your carrier to confirm how it handles roaming on a secondary data plan.
Does an unlimited eSIM really mean unlimited data for a month abroad?
Unlimited on Maya means no data bucket to watch across the 30 days, with a daily high-speed allowance stated in the terms. The terms spell out the allowance, so you know what to expect before you buy.
All plans include a daily high-speed allowance, called the Daily Quota, at up to 4G LTE or 5G where local networks offer it. Unused Daily Quota does not carry over. We offer multiple Unlimited eSIM plans with different amounts of daily high-speed data. By default we send a data usage notification when an eSIM is close to using all its available data. These plans are designed for individual travelers using data on the move.
Slow data is the complaint to check for at any provider. In a 2-star Trustpilot review on October 9, 2026, a travel eSIM customer wrote: “Once connected, the signal strength and data speed was slow at best.” Read the allowance line in the terms before you buy, and read it against all 30 days.
Can you keep your U.S. number for calls and texts with an eSIM abroad?
Yes: the eSIM carries your data and your U.S. SIM stays on the phone for your number. Calls and texts through WhatsApp, FaceTime and similar apps use the eSIM’s data, so the number matters less than it did.
Our eSIM works alongside your existing carrier SIM, with no SIM removal needed. The plan is data only. Calling and text messaging are not included, but you can browse the web, get directions and use other apps.
Roaming charges are not billed as long as the eSIM is installed and configured correctly and Data Roaming is off on your regular phone plan. Calling and texting on your regular number over Wi-Fi Calling works only if your carrier supports it, and some carriers may charge international SMS fees even then. Over 11,000 Maya eSIM reviews come from real travelers.
Will your phone work with a travel eSIM, and how fast is setup?
You need an eSIM-capable phone, and the usual condition is that it is unlocked from the carrier. Maya installs once and stays on the phone, so there is no setup to repeat when you land.
Check your model at maya.net/esim-compatible-devices. If your device is not eSIM compatible, we cannot provide service to it.
On iOS, open the Maya Mobile app, go to Home, select the eSIM, choose Installation Instructions, tap Install eSIM Now and follow the prompts. Most often the eSIM is already installed on the phone, which can happen in the background after scanning the QR code. The eSIM activates in a minute or two. Installing it adds a secondary line for mobile data, and your U.S. line stays as it was.
What happens when your trip crosses countries, or ends on a cruise?
A month abroad rarely stays in one country, and a per-country plan adds a purchase at every border. Maya covers 165+ countries on one price by trip length, so crossing a border is not a new purchase.
One plan covers multi-country travel, so the same plan and eSIM cover countries you add; a longer trip needs another plan, and the eSIM stays installed. The price is the same in every country.
Cruise coverage is the Global + Cruise plan, a separate purchase priced on its own: USD 299.99 for 30 days. It covers 20+ cruise lines, including Norwegian Cruise Line and Royal Caribbean International. Cruise connectivity runs over satellite and maritime networks and depends on vessel and route, so speeds at sea may differ from land.
Service in a specific country is not guaranteed and may vary for reasons outside our control.
Thirty days, one price, one eSIM
The pass looks safe because it is familiar. For 30 days, though, a flat USD 49.99 with unlimited data beats a $75 pass with a 30 GB ceiling, and the calls on your U.S. number stay where they were. The month costs what the plan says it costs.

Frequently asked questions
How much does a 30-day travel eSIM cost compared with T-Mobile’s International Pass?
Maya’s 30-day plan is USD 49.99, or USD 1.67 per day, for unlimited data in 165+ countries. T-Mobile’s 30 Day Pass is $75 for 30 GB (t-mobile.com, 2026). Maya has no control over your home carrier’s plan, so check your carrier’s page for its current price.
Can I use my phone as a hotspot on an unlimited eSIM?
Yes. Hotspot is included with every plan, though availability depends on the local network operator and may be restricted in some situations. Using your hotspot for a laptop or tablet to join Zoom calls is fine. Downloading huge files or using the hotspot as a router for multiple computers may be limited, as set out in our acceptable use policy.
What happens if I need more than 30 days abroad?
For a longer trip, you buy another plan from your Maya Mobile account. Auto Top-Up is the optional feature that buys the same plan again when the current one expires. It is off by default, and you can turn it off any time from My eSIM.
Do unlimited eSIMs slow down after a certain amount of data?
On Maya, the Daily Quota gives you high-speed data at up to 4G LTE or 5G where local networks offer it, and it resets every 24 hours from activation. Once it is used, data continues at standard speed for the rest of the day. No speed is guaranteed, and actual speeds vary by location and local network.
When should I install an eSIM before I travel?
Install it once before you travel. The plan clock starts when you enable the Maya eSIM in your phone settings, so switch it on when you land and select it for Cellular Data. The Maya Mobile app confirms when the eSIM is ready. A QR code works for one installation only, so use it with a brand-new eSIM.
Can I get my money back if the eSIM does not work?
We offer a money-back guarantee if the eSIM cannot be installed or used. The conditions are in our return policy. Full refunds are less any applicable payment processing fees.
Maya gives a 30-day trip one flat USD 49.99 price, with unlimited data across 165+ countries and your U.S. number left alone.
