A small team obsessed with getting you connected
One Union Mobile has been in the eSIM business since 2021. You choose a plan online and pay once — as soon as your payment is confirmed, your personal QR code lands in your inbox and your dashboard.
Who we are
One Union Mobile has been in the eSIM business since 2021. We started because travellers and remote workers needed a simple, reliable way to get a US mobile line without visiting a store or swapping physical SIM cards.
Today we serve customers around the world with one promise: once your payment is confirmed, your order is delivered. Every QR code, refill and support request is handled carefully, because we know your connection matters.

What we sell
US eSIM bundles with 5G data, unlimited nationwide talk and text, international calling to more than 100 countries. Everything runs alongside your existing physical SIM, so your home number keeps working.
When your month runs out you do not need to buy a new eSIM — just submit a refill request with your number and we top the same profile up.

How we work
The standards we hold ourselves to
Reliable delivery
Once your payment is confirmed, your order is delivered. You receive your QR code by email and it stays available in your dashboard for easy access.
Fast by design
Most eSIMs are delivered within minutes of payment being confirmed, and you can follow the status of your order in your account at any time.
Real US numbers
We focus on doing one market properly rather than a hundred badly: real US numbers with data, nationwide talk and text and international calling.
Your data stays yours
We collect only what is needed to issue and support your eSIM. QR codes are stored in private storage and only you and our support team can reach them.
Honest pricing
The price on the plan card is the price you pay. No activation fees, no autopay and no surprise charges at the end of the month.
