eSIM India: Set It Up at Home, Use It From Delhi to Chennai

For most destinations you could, in theory, sort out your eSIM after arrival. For India, plan it differently: because of local regulations, buy the India eSIM and install it while you are still at home. Treat it like your visa paperwork, something that is finished before you pack.

This costs you nothing in terms of validity. The plan does not start on the day you buy or install it, but only when the eSIM first connects to a supported network in India. You have 180 days from the purchase to make that first connection, so even a trip booked months ahead is no problem.

The eSIM connects to local networks in these cities and in other places across the country:

- North: Delhi and Lucknow
- West: Mumbai, Pune, Ahmadabad and Surat
- South: Bangalore, Chennai and Hyderabad
- East: Kolkata

If you searched for an eSIM in Mumbai or a plan just for Delhi, you do not need a separate one: a single India travel eSIM covers all of these cities. Depending on the operator and the area, your phone uses 3G, 4G/LTE or 5G, and the operator's fair-use rules can reduce the speed.

Give yourself a quiet evening at home with stable Wi-Fi. Three things need doing:

Confirm that your phone accepts an eSIM

The phone has to be eSIM-capable and free of a carrier lock. One thing to keep in mind: some iPhone models sold in mainland China, Hong Kong and Macau come without eSIM support.

Order the plan

Select India on the eSIM page, pick a data plan, log in and pay from your Anosim balance. Top-ups work with cryptocurrency or bank transfer, and nobody asks for an ID.

Scan the QR code, then leave the eSIM off

Your phone needs an internet connection while it adds the profile. The QR code is single-use: keep the installed profile, never delete it to start over, and contact support instead of scanning a second time. Afterwards leave the eSIM switched off until India.

Once the plane is on the ground, go to your phone's mobile settings. Turn the eSIM on, make it the line used for mobile data and enable data roaming for it. Expect an Indian network to appear on the display within one to two minutes.

If the status bar stays empty, run through this short list: restart the phone, put it into airplane mode for a few seconds and back, and make sure network selection is on automatic. Our support team is reachable around the clock via Telegram, the website chat and email if you still have no data.

Whether you are visiting an office in Hyderabad or travelling as an eSIM India tourist through several states, the use cases overlap: navigation, ride-hailing, messengers, email, video calls, photo uploads and streaming all run over the data plan. WhatsApp calls and other internet calls work too.

Sharing the connection with a laptop is a different question. Hotspot depends on the network operator, so it is safer not to build a work day around it.

The eSIM has no Indian phone number. Your regular SIM keeps your usual number active in the phone, so contacts still reach you on WhatsApp as before.

Some services want to confirm a phone number by SMS before you can use them. A data plan cannot receive that message. Anosim has numbers for exactly this situation, and they work next to the eSIM:

- Activation: a number for a single Indian sign-up code.
- Rent Service: a number kept for a single service that may ask for a code again later.
- Rent Number: a full number you can use for any service.

If a number is virtual, it is labelled as such in the provider selection.

Comparisons of the best eSIM for India tend to start with price. For this country, two other points come first: can you complete everything at home, and does the plan start only when you arrive? Both apply to this prepaid eSIM for India. Add a compatible phone, no ID check and payment from your balance, and the India eSIM is ready to go.

Is India one stop on a longer route? The Sri Lanka eSIM and the Maldives eSIM have their own pages, and every other destination is listed on the eSIM overview.
