Getting Started with Partner Plans on Umi

You’ve received a special plan from one of Umi’s partners — great choice!

Follow these quick steps to get connected.

Umi is your Smart Global eSIM — a digital SIM that lets you stay connected anywhere in the world.

No more roaming fees, or constantly swapping and reinstalling SIMs every time you travel.

With Umi, you only install once. It works alongside your existing SIM or mobile plan, so you can keep your regular number for calls and texts while using Umi for data when abroad on backup when at home.

You can add or redeem data plans directly inside the app, including special plans from our partners. When you arrive in a new country, your plan activates automatically, and you’re online within seconds — no setup, no waiting, no confusion.

Umi brings together simplicity, speed, and flexibility — giving you reliable mobile data around the world, all from one app and one eSIM.

1. Download the app from App Store or Google Play. 

2. Sign up using your email.

3. Allow permissions when prompted (e.g., notifications, location).

You can receive a partner plan in one of two ways:

Option A — Via Link

• Tap the link you received from the partner.

• It will automatically open the Umi app.

• You’ll see a message confirming the partner plan has been added to your account.

Option B — Via Referral Code

• Open the Umi app → Data page → Crown button. You can also enter it during onboarding when asked for a referral code. 

• Enter the partner code (its case sensitive).

• Once accepted, your plan will appear on the screen.

• Tap your Partner Plan → Attach → Attach to new eSIM.

• On the home screen, press Install eSIM Now and follow the guided steps to install your Umi eSIM. When prompted, label it as Umi to keep things clear.
• Follow the in-app instructions to adjust your phone’s settings:
• Turn Data Roaming ON for your Umi eSIM.
• Turn Data Roaming OFF for your primary SIM to avoid roaming charges.
• Once your eSIM is installed and settings are configured, you’re all set.
• Turn off your Umi eSIM until you need it. 

When you arrive at your destination:

• Turn on your phone or disable Airplane Mode.
• Make sure your Umi eSIM is selected for mobile data

• 🍎 iPhone: Settings → Mobile Service → Mobile Data → select Umi eSIM
• 🤖 Android: Settings → SIM Management → Default Mobile Data → select Umi eSIM

• Your attached plan will activate automatically once your eSIM connects to a local network.

• What is an eSIM?
  An eSIM is a digital SIM card built into your phone. It lets you connect to mobile networks without needing a physical SIM — just download and activate it once.

• What phones are compatible with Umi?
  Most modern smartphones that support eSIM are compatible — including recent iPhone, Google Pixel, and Samsung Galaxy models. You can check your device’s settings for an “Add eSIM” or “Mobile Data Plan” option.

• Do I need to remove my regular SIM card?
  No. Umi works as a secondary eSIM, meaning you can keep your regular SIM for calls and texts while using Umi for mobile data when you travel.

• When does my plan start?
  Once attached to your eSIM, your plan activates automatically when you connect to a supported network — usually right after landing in your destination. Just turn on your phone and switch your data connection to your Umi eSIM in your phone’s settings.

• Do Umi plans include calls or texts?
  Umi plans currently provide data only. You can still use apps like WhatsApp, iMessage, or FaceTime for calls and messages.

• Can I top up or buy more data later?
  Yes. You can add more data or purchase additional plans anytime in the Umi app.

• What if I can’t connect when I arrive?
  Make sure Mobile Data is turned on, the Umi eSIM is set as your active data line, and Airplane Mode is off. If you still can’t connect, restart your phone or open the Help → Connection Guide in the app.

• What networks does Umi connect to?
  Your Umi eSIM connects to an available partner network in over 200+ individual destinations around the world.
