Indiachecked Aug 2026A catch or twoStaying connected in India.
India is the clearest case on this site of the honest answer costing us money. A local SIM here is not slightly cheaper than a travel eSIM, it is roughly a tenth of the price. What it costs you instead is an hour of paperwork and, occasionally, a day of waiting.

Cheapest
A local SIM, about $4 a month

Passport, visa, photo in the shop
Coverage is broad: 4G across most of the country and 5G in the cities, thinner in the Himalaya, parts of the northeast and deep rural districts. The honest headline here is not the eSIM. A local prepaid SIM from Jio or Airtel costs about 300 rupees, near 4 dollars, and carries 1.5GB to 2GB a day for 28 days with unlimited local calls, which is more data than most travelers use in a month for less than one day of carrier roaming. Your US carrier charges about 10 to 12 dollars a day (AT&T and Verizon day passes), and T-Mobile is worth checking first, because its mid and upper tiers include a real high-speed allowance abroad, from 5GB up to 30GB depending on plan, slowing to 256kbps after that. What the local SIM costs you is paperwork: your original passport, your visa, an address, a photograph taken in the shop, and anywhere from 15 minutes to 48 hours before it works. A Nomad eSIM buys you arrival-day certainty and nothing else, which is a real reason to choose it and not a price argument. Never roam pay-per-use, at about 2 dollars a megabyte.
The local SIM is the cheap answer, and it is not close
A prepaid plan from Jio or Airtel, India's two strongest networks, costs about 300 rupees, near 4 dollars, and carries 1.5GB to 2GB a day for 28 days along with unlimited local calls. Put that beside the alternatives and the gap is not a rounding error: a week of AT&T or Verizon day passes is 70 to 84 dollars, and a travel eSIM with a sensible allowance is a few dollars per gigabyte. The local SIM undercuts both by a wide margin, and we earn nothing when you buy one.
So the recommendation on this page is a local SIM for anyone staying more than a couple of days, and the reason is arithmetic rather than preference. Airtel has the better reach in the hills and the northeast, Jio has the widest 5G and usually the larger daily allowance, and in the cities either is fine. What you should not do is roam with no plan: pay-per-use runs about 2 dollars a megabyte, thousands per gigabyte, and background app activity alone will find it, so turn off data roaming until something is active.
What the paperwork actually costs you
India enforces KYC registration on every prepaid SIM, and for a visitor that means turning up in person at a carrier store or an airport counter with your original passport rather than a copy, your Indian visa, an address where you are staying, usually a hotel booking, and a photograph taken there and then. Activation is commonly two to four hours and can stretch to 48, and you may have to make a short verification call before incoming calls work. Budget an hour of your first afternoon and it is a non-event; budget nothing and it can eat your arrival day.
Two warnings worth more than the money they save. Vendors offering a pre-activated SIM, no passport needed are selling a line registered to a stranger, it stops working within days, and it is not a shortcut. And a local carrier eSIM is no easier than a physical one here, because a visitor still has to do the same in-store registration and wait for approval. The eSIM that actually skips the queue is an international travel eSIM bought before you fly, which is a different product from a Jio or Airtel eSIM.
Where roaming and a travel eSIM still make sense
The expensive default is roaming on your US plan: AT&T and Verizon day passes run about 10 to 12 dollars a day, so a week is roughly 70 to 84 dollars. T-Mobile is the exception worth checking first, because its current tiers include a genuine high-speed allowance abroad, roughly 5GB on Experience More, Magenta MAX and Go5G Plus, 15GB on Experience Beyond and Go5G Next and 30GB on Better Value, slowing to 256kbps only once that is used up. The entry Essentials tier is throttled from the start. Google Fi and Visible set their own terms, so read your own plan rather than assuming.
The honest case for a Nomad eSIM in India is the first day: a car to arrange at 2am in Delhi, a UPI-adjacent app to load, a hotel to find, all before any store is open. It is a few dollars per gigabyte, it activates before you fly, and it is the wrong choice if what you care about is the total bill. Many travelers do both, an eSIM for landing and a local SIM the next afternoon. On coverage, expect thin patches in the Himalaya, the far northeast and deep rural districts, so download offline maps for hill driving. This guide is written for US travelers departing the US.

Common questions
Quick answers.
Is an eSIM cheaper than a local SIM in India?
No, and not by a little. A Jio or Airtel prepaid plan is about 300 rupees, near 4 dollars, for 28 days at 1.5GB to 2GB a day. A travel eSIM costs several times that for less data. The eSIM buys you a working phone the moment you land and no store visit, which is worth something, but in India it is the convenient option rather than the cheap one.
What do I need to buy a SIM card in India?
Your original passport rather than a copy, your Indian visa, the address where you are staying and a photograph taken in the shop. Registration is required by law. Activation usually takes two to four hours and can take up to 48. Avoid street vendors selling pre-activated SIMs with no documents, since those are registered to somebody else and stop working within days.
How much does it cost to use my US phone in India?
About 10 to 12 dollars a day on an AT&T or Verizon day pass, so roughly 70 to 84 dollars a week. AT&T caps its Day Pass at 10 daily fees per line per bill period, so about 120 dollars covers the rest of that bill period on land, while Verizon's TravelPass has no equivalent cap and keeps billing daily, which matters on a trip longer than 10 days. T-Mobile is worth checking first, since its mid and upper tiers include 5GB to 30GB of high-speed data abroad before slowing to 256kbps. Never roam with no plan, since pay-per-use runs about 2 dollars a megabyte.
Which Indian mobile network is best for travelers?
Airtel has the better reach in the hills and the northeast, and Jio has the widest 5G and usually the larger daily data allowance. In the cities either is fine. Coverage is broad nationally, with thin patches in the Himalaya, parts of the northeast and deep rural districts.

The little money things nobody warns you about.
- Do I need cash in India, or can I use cards?Short answer: cards for hotels and larger purchases, and cash for daily life. Locals pay by UPI apps that are hard for visitors, so carry rupee cash in small notes. Here is how to handle it.
- Tipping in IndiaIndia runs on baksheesh: small tips for service, given often. About 10% at restaurants, plus small amounts for the many people who help you. Here is what you actually owe.
- How do US citizens get an India e-visa?Short answer: online, on one official government site, before you travel. US citizens need an India e-Tourist Visa, the process is straightforward, but the search results are full of overpriced middlemen. Here is the real fee and the real site.
- Taxi apps in India, and the airport touts to skipIndia's taxis are cheap, but the first hour at the airport is where the tricks cluster. Here is the app to install, how to tell the real prepaid taxi from the touts, and the small scams to know once you are moving.
- Common money scams in India, and what they cost youIndia is an extraordinary trip that rewards a little preparation, and the scams that target tourists are money ones, not danger: overcharging, commission steering and a few well-known setups. They follow the same patterns almost every time, so once you know them they are easy to sidestep. Here is each one and how.
- What does getting sick in India cost a visitor?India runs two medical stories at once. Everyday care is fast and genuinely inexpensive. Private hospitals in India ask for an advance deposit before they will admit you, and that deposit, not the consultation fee, is what decides where and how quickly you are treated.

Our own readChecked Aug 2026. Two things to be plain about. First, we earn a commission on eSIM links and nothing at all on Indian prepaid SIMs, so a page telling you to buy the local SIM is a page arguing against our own revenue, which is the only way this section is worth reading. Second, Indian tariffs have risen in steps over the past two years and will again, so treat 300 rupees as a current entry point rather than a fixed price, and treat the activation window as the genuinely variable part: airport counters can be quick, a neighborhood store on a busy afternoon is not. Carrier day-pass figures are an Aug 2026 snapshot and move faster than anything else here, so check your own plan before you fly.
