How to buy a travel eSIM with Claude
Once the Hungry eSIM connector is added, buying data for a trip is a conversation rather than a catalogue crawl. Below is what that actually looks like, turn by turn. If you have not connected the server yet, start with the setup guide.
1. Describe the trip, not the product
You do not need to know how many gigabytes you use. Say where you are going and for how long, and let the assistant map that onto plans.
You
I'm in Tokyo for 9 days next month. What eSIM should I get?
Claude
I found a few options for Japan. If you mostly use maps, messaging and the occasional video, a fixed-data plan is the cheapest way to cover the trip:
· Japan 3GB / 15 days — $3.45
· Japan 5GB / 30 days — $5.40
· Japan 10GB / 30 days — $9.40
There is also an unlimited plan where you choose the number of days, so you would pay for 9 rather than a fixed 15 or 30. Want me to price that?

2. Pay for the days you are actually away
Most eSIM plans come in fixed blocks — 7, 15 or 30 days — so a 9-day trip means buying 15. Hungry eSIM's unlimited plans take the number of days as an input, and the assistant passes it straight through when it builds the cart.
You
Yes — price the unlimited one for exactly 9 days.
Claude
Japan unlimited at 1GB/day full speed, reduced after that, runs about $2.42–2.65 per day depending on the throttle tier — so 9 days is roughly $22–24.
Worth saying: the 10GB fixed plan above covers the same trip for $9.40. Unlimited is the better buy only if you expect to go well past 10GB. Which way do you want to go?

Day counts run from 1 to 30. As the example shows, unlimited is not automatically the better deal — past roughly a week and a half a fixed-data plan is often cheaper for the same trip. The product page flags this too, rather than letting you overpay quietly.
3. The assistant builds the cart; you pay
The server never charges a card. It creates a cart and hands back a checkout link on hungry-esim.com, where you pay the normal way — by credit card, with the usual receipt, refund policy and support behind it. No crypto wallet and no prepaid balance.
You
Go ahead.
Claude
Here is your checkout link — hungry-esim.com/mcp/checkout/…
I have not charged anything. Open it and pay by credit card; the QR code is emailed to you as soon as the order goes through.
4. Get the QR code back in the chat
The QR code is emailed as soon as the eSIM is issued, and the assistant can fetch it again at any point from the order number — handy when the email is buried and you are standing at an airport.
You
Paid. Order 1042 — can you pull up the QR?
Claude
Order 1042 is provisioned. Here is the QR code and the LPA activation string, plus a one-tap install link for iOS.
Install it before you fly and switch it on when you land.
5. Top up mid-trip without a new eSIM
This is the part that usually falls outside a chat. After a one-time sign-in, the assistant can list the eSIMs on your account, see which ones accept more data, and build a top-up checkout link for the one you already installed.
You
I'm on day 8 and burned through my data. Can you add more?
Claude
Your Japan eSIM can take a top-up — I can pull the packages that fit the time you have left and show you the prices.
A top-up loads onto the eSIM you already installed, so there is no second QR code and nothing to re-scan.
Top-ups and the rest of the account tools ask you to sign in once, in a browser. Searching, pricing and buying a first eSIM need no account at all.
Things worth asking
- "Two weeks across Thailand, Vietnam and Cambodia — one eSIM or three?"
- "Cheapest 5GB plan for Spain that lasts 30 days."
- "Does the Japan unlimited plan slow down, and at what point?"
- "Which of my eSIMs is still active?"
