If you're traveling abroad, you can either activate international roaming on your Airtel or Jio number or use a travel eSIM for mobile data. Both options can keep you connected, but the cost, setup, data allowance, and flexibility can differ.
Airtel or Jio roaming lets you continue using your existing Indian number while traveling, which can be convenient if you need calls, texts, or OTPs. A travel eSIM, such as SimJu, gives you a separate data connection without requiring you to remove your physical SIM.
So, which option is better for international travel? It depends on how much data you need, whether you need your Indian number active, and how you want to manage your mobile connection abroad. This guide compares Airtel and Jio roaming with travel eSIMs to help you choose the right option for your trip.
Airtel/Jio Roaming vs eSIM: What Is the Difference?
Airtel or Jio international roaming keeps your existing Indian SIM connected to a partner network abroad. A travel eSIM, on the other hand, gives you a separate mobile data plan for your destination. The main differences are how you connect, what you pay for, and how you manage your Indian number while traveling.
How International Roaming Works
International roaming allows your Airtel or Jio SIM to connect to a supported network in another country. After activating a roaming pack or service, you can use mobile data, calls, and SMS based on your plan. Your Indian number remains active throughout the trip.
How a Travel eSIM Works
A travel eSIM is a digital SIM that you install on a compatible, unlocked phone. You purchase a destination-specific data plan, install the eSIM, and select it as your mobile data line when you travel.
With SimJU, you can use the eSIM for travel data while keeping your Airtel or Jio SIM in the phone.
What Changes When You Switch to an eSIM?
Switching to an eSIM does not mean you have to remove or deactivate your existing SIM. On a compatible dual-SIM phone, you can keep Airtel or Jio active for your Indian number and use the eSIM for mobile data
