Why Union Sim
Built for people who actually travel
Verified before delivery
Every profile is verified against the carrier before it is released, so it works the first time you scan it.
Tier-1 partner networks
We buy capacity from national carriers, not grey-market resellers. Expect real 4G/5G speeds where coverage exists.
Transparent pricing
The price you see is the price you pay. No activation fees, no autopay, no surprise overage billing.
Keep your main number
Your eSIM runs alongside your physical SIM, so calls and messages on your home number keep working.
Your QR, forever available
Every QR code and set of activation notes stays in your account dashboard — re-download it any time.
Support that answers
Round-the-clock help by email, contact form or WhatsApp from people who actually troubleshoot eSIMs daily.
Billing
No autopay. Ever.
Union Sim does not store payment details and does not renew anything on its own. Your plan simply runs to the end of its validity period.
48 hours before
A first reminder appears in your dashboard telling you exactly when the plan ends.
24 hours before
A final reminder so you have time to refill before the number goes quiet.
You decide
Refill, change plan or do nothing. If you do nothing, the plan simply stops — no charge.
Your next trip deserves better than airport Wi-Fi
Choose a plan today, install the eSIM before you fly, and switch it on the moment you land.
