What is an eSIM? A short guide for travellers from India
An eSIM is a SIM built into your phone. You download a mobile plan to it, usually by scanning a QR code, instead of inserting a plastic card. For a trip abroad, a travel eSIM gives your phone mobile data while your Jio, Airtel or Vi SIM stays in the phone for calls and OTPs.
What is an eSIM? It is an embedded SIM: a chip fixed inside the phone that stores a mobile plan as a downloadable profile. It does the same job as a plastic SIM and connects the phone to a network. It works only on a phone the maker built with eSIM, so check your model first.
“eSIM meaning” and “eSIM card” point to the same thing, though there is no card to hold. What you receive is a QR code or an activation code, and scanning it installs a QR code profile on the chip. “Digital SIM” and “e-SIM” are other names for the same technology; the glossary lists the related terms in one place.
Most eSIM phones can store more than one eSIM profile, and many can run an eSIM next to a physical SIM. Whether your model can do both comes from the maker’s specifications, not from your operator.
How a travel eSIM works on a trip abroad
A travel eSIM is a mobile data plan for one country or region, bought online before you fly. Install the eSIM in India; it connects when you land abroad. Maps, WhatsApp, ride apps and e-tickets run over it. Most plans include no calls and no SMS, so calls and OTP texts stay with your Indian number.
A few plans add a local foreign number with minutes and SMS, and the plan card on the country page says so. No plan carries your Indian number.
The sequence is short. Check that your phone supports eSIM and is not locked to one operator. Buy a plan for your destination from our country pages, then scan the QR code on home Wi-Fi to install the profile; the install guide shows the steps. Set mobile data to the travel line and keep the Indian line on for SMS, with its mobile data off. When you land, the eSIM connects to a local network.
A travel eSIM is the wrong tool in two cases. It does not replace your Indian number, so calls and SMS sent to that number never reach it. And it does not work on a phone without eSIM support; there, an operator roaming pack or a local physical SIM is the option.
For almost every destination we sell, the plan days start at the first connection to a network abroad, not at installation; the country page states the rule for each destination. Full refund within 30 days of purchase, as long as the eSIM has not connected to any network. If the eSIM doesn’t work and it isn’t your phone’s fault, we refund the payment whether or not it was installed.
Your card is charged in US dollars. Your bank converts the amount at its own rate and may add a foreign-transaction (forex markup) fee. How card payments work.
Does an eSIM change your number?
No. A travel eSIM is a second line with its own profile, and it does not touch your Indian number. Your Indian SIM stays in the phone for calls and bank OTPs, and nobody has to learn a new number. The only limit is your phone: it must run two lines at once.
Bank OTPs arrive as SMS on your Indian number. Your travel eSIM has no Indian number, so it cannot receive them. Keep your Indian SIM active in the phone with its mobile data off. Whether SMS reaches you abroad depends on your operator and plan, and no page can promise that every OTP will arrive. The guide to keeping your Indian SIM for OTPs explains the settings and the operator switches.
eSIM vs a physical SIM in one paragraph
A physical SIM is a card you swap; an eSIM is a profile you download. That lets you add a travel plan from home without a SIM tray, a pin or a shop visit. The trade-off: you need a phone with eSIM support, and some phones keep only one eSIM active at a time.
If your Indian line is a plastic SIM, the phone must run an eSIM and a physical SIM together. If your Indian line is already an eSIM, the phone must keep two eSIMs active at once. The full eSIM vs physical SIM comparison covers airport SIMs and roaming packs.
Check your own phone before you buy, because models with the same name can differ by country. Our phone list is built from the makers’ Indian pages, checked on 12 Oct 2026. On those pages, the OnePlus 12, Motorola Edge 60 Fusion and Nothing Phone (3a) Pro have no eSIM in India; Nothing lists eSIM for the Phone (3a) Pro “excluding India”. A phone sold on an operator contract may be locked to that operator, so ask the operator before you buy a plan.
