Step 1: eSIM Activation
Before you begin, please make sure:
- You are on a stable WiFi connection
- Airplane mode is OFF for your device
Activating your Roam eSIM
- You will need to send the QR code to another device near you (like your laptop, tablet, or friends phone)
- Scan QR code from device where you want to use your eSIM
- You will get the Activate eSIM screen. Click Continue
- Follow process on device
Once you activate your eSIM, the usage period will start from that moment.
Your eSIM will take 1–2 minutes to activate. Please ensure your screen does not go dark during this process.
Configuring iOS Default Settings
- When you see Cellular Setup Complete, click Continue
- For Default Line, select Primary and click Continue
- For iMessage & FaceTime, select Primary and click Continue (this is critical)
- For Cellular/Mobile Data, select Primary and turn ON Allow Data Switching, then click Continue
Please note the label assigned to your new eSIM by iOS. It will likely be labeled Personal, Travel, Secondary, Business, or Cellular Data. You’ll need this label in the next step.
Step 2: eSIM Settings
- Go to iPhone Settings → Cellular/Mobile and scroll to the SIMs section
- Tap on the Roam eSIM (usually labeled Personal, Secondary, Travel, Business, or Cellular Data)
- Turn Data Roaming ON for Roam eSIM
- Go back and tap on your Primary SIM (the one with your regular phone number)
- Turn Data Roaming OFF for your Primary SIM
Configure Cellular/Mobile Data
- Go back, scroll up, and tap on Cellular/Mobile Data
- If you want Roam to automatically take over when abroad:
- Select Primary AND
- Turn ON Allow Data Switching
- If you prefer manual control:
- Select Roam eSIM when abroad
- Select Primary SIM when back home
(Recommended) Enable Low Data Mode
- Go to iPhone Settings → Cellular/Mobile
- Tap on Roam eSIM
- Tap on Data Mode
- Select Low Data Mode
This avoids background data use without affecting speed when you actively use your phone.
Final Note
-
As long as Data Roaming is OFF for your Primary SIM, you will not be charged for data roaming.
-
However, your mobile operator might still charge for calls or SMS. Receiving SMS is always free — even abroad. To completely avoid roaming charges, you can turn OFF your Primary SIM while traveling. Just note: you won’t be able to receive SMS with it off.
-
Usage Validity is to confirm sim usage period
-
eSIM QR code validity once purchased, eSIM is valid 28 days from the date of purchase and it must be activated within 28 days
