  • Avoid Costly Roaming: Say goodbye to bill shock. Our transparent, upfront pricing means you know exactly what you’re paying for. No hidden fees, just affordable data.
  • Flexible Plans: Don’t get locked into a plan you don’t need. With Yoho Mobile, you can build a plan that perfectly matches your trip, choosing the countries, data amount, and duration you need.
  • Peace of Mind with Yoho Care: Ever worried about your data running out unexpectedly? With Yoho Care, you get a safety net of backup connectivity, ensuring you’re never left offline when you need it most.

Before You Begin: Pre-Setup Checklist

To ensure a smooth setup process, take a moment to run through this quick checklist. Having these things in order will make activating your eSIM a breeze.

  1. Check Device Compatibility: The OnePlus 15 is designed with eSIM in mind, but it’s always a good idea to confirm. You can view a comprehensive list of compatible devices on our eSIM compatibility page.
  2. Stable Internet Connection: You’ll need a stable Wi-Fi connection to download and install the eSIM profile onto your device.
  3. Carrier-Unlocked Phone: Your OnePlus 15 must be unlocked from any carrier restrictions to accept an eSIM from another provider. If you bought it directly from OnePlus, it’s likely unlocked. If purchased through a carrier, you may need to contact them to unlock it.
  4. A Yoho Mobile Plan: You’ll need to have a plan ready to activate. If you haven’t already, explore our affordable data plans for over 200 countries and regions.

Step-by-Step Guide: Activating Your Yoho Mobile eSIM on OnePlus 15

Ready to get connected? Follow these simple steps. This is how to activate an eSIM on your OnePlus 15 for travel or home use.

Step 1: Find Your QR Code

After purchasing your plan from Yoho Mobile, you will receive an email containing a QR code. This code is your key to activating the eSIM. Have it ready on another device (like a laptop or tablet) or print it out.

Step 2: Navigate to Network Settings

On your OnePlus 15, open the Settings app. Tap on “Network & internet” and then select “SIMs”.

Step 3: Add a New eSIM

Look for an option that says “Add eSIM” or a plus (+) icon. This will initiate the process of adding a new cellular plan to your phone.

Step 4: Scan the QR Code

Your phone will prompt you to scan a QR code. Use your OnePlus 15’s camera to scan the code you received from Yoho Mobile. The phone will automatically detect the eSIM profile details.

Step 5: Follow the On-Screen Prompts

Your device will guide you through the final confirmation steps. It will download the eSIM profile and add it as a new line on your phone. This usually takes less than a minute.

Step 6: Label and Configure Your eSIM

Once installed, it’s a great practice to label your new eSIM. Go back to your SIM settings, select the new eSIM, and name it something memorable like “Yoho Travel.” Then, you can set it as your preferred SIM for Mobile Data. Ensure Data Roaming is turned ON for your Yoho eSIM if you are traveling internationally. It’s necessary to connect to our partner networks, but don’t worry—you will only be charged based on your prepaid Yoho Mobile plan.
