The business-trip eSIM that takes a Taiwan tax ID (統編)

soda is registered in Switzerland, so what you get is a Swiss receipt rather than a Taiwanese uniform invoice. That receipt carries your company name and tax ID, and you can export a monthly reconciliation list — which is more than most offshore sellers give you.

Get started

Your receipt has what your expense claim needs

Expense reportExample

  1. Tax ID and company name, once

    Save your company name and 8-digit tax ID in billing settings (checksum-validated on the spot) and every top-up receipt carries them automatically.

  2. Usage-based — finance pays only what was used

    No guessing plan sizes for travelling colleagues: usage billing with retroactive settlement, and every receipt includes the full price comparison.

  3. Monthly reconciliation

    Export a monthly list of every top-up — amount, date, company name, tax ID — ready for your accountant to reconcile.

Top-up receiptExample
  1. Issued bysoda (Swiss entity)
  2. Company name(Your company name)
  3. Taiwan tax ID(8-digit tax ID)
  4. Date2026/11/02
  5. ItemTop-up
AmountUS$20.00

This isn’t a Taiwanese uniform invoice and can’t be used for input VAT credit.

How expensing works

  1. 01

    Enter your tax ID and company name once

    Fill them in under “Company name & tax ID” in the app. The tax ID’s check digit is verified before it’s saved.

  2. 02

    Top up, and it’s on the receipt

    Every top-up receipt from then on shows your company name and tax ID.

  3. 03

    Export a monthly list

    Amounts, dates, company name and tax ID in one file for your accountant.

Straight talk

Coverage today: Japan, South Korea, Thailand, Singapore, Malaysia, Hong Kong, Switzerland, Indonesia, the Philippines, the United States, China and Macau, plus a regional line covering 34 European countries. Top-up receipts carry your tax ID, with a monthly reconciliation export. Receipts are issued by soda’s Swiss entity: they are not Taiwanese uniform invoices and cannot be used for input VAT credit, so check first whether your finance team accepts offshore receipts.

Frequently asked questions

Why does a regional card's receipt not list the countries I visited?
The carrier behind a regional line does not report usage country by country, so we cannot print that breakdown. The bill shows one country code to stand for the whole line; it is there for accounting and does not record where you actually went. Single-country lines are not affected.
When do I pay? Is this postpaid?
You only pay when you top up. Confirmed charges and pending estimates appear in the wallet and settle against your credit; soda never makes an automatic extra charge to your payment card. Delayed upstream usage settles when it arrives.
Does my balance expire? Can I get a refund?
Your balance never expires and carries over to your next trip. Within the cooling-off period, the part you haven’t used can go back to your original card. A refund may turn off the eSIM bought with that top-up, and the app lists it before you confirm.
How do I sign in? Is there a password?
There is no password. Enter your email and continue; the first time you do, the account is created. You can add a passkey on the device afterwards for one-tap sign-in.
