Everything you need to know about using an eSIM in India.
India runs on one of the world's most competitive mobile markets. Jio, Airtel, and Vi blanket the country in 4G, with 5G lighting up across major cities. Any unlocked eSIM-compatible phone will find a strong signal almost anywhere you go, from the streets of Delhi to the back roads of Kerala.
The catch is the paperwork. India is one of the few countries where SIM registration is genuinely statutory: the Telecommunications Act 2023 makes identity verification of every subscriber a legal requirement, with biometric checks written right in. Residents tie their SIM to Aadhaar, the 12-digit biometric ID, through a fast digital e-KYC that permanently links the number to your fingerprints.
No Aadhaar? Then you verify with your passport, your visa, and a passport photo at an authorized operator store. It's an in-person KYC ritual: hand your passport over a counter, wait for someone to photograph it and key your details into a system, and your identity, number, and call records get filed with a carrier and the Indian state.
Even a tourist eSIM from Jio or Airtel still demands the full passport-plus-visa-plus-photo KYC. There is no low-friction local option, and there's no way around it.
And the trail doesn't end at the counter. Indian carriers are required by their licence to keep call detail records for two years, and the state can order interception of any message on security grounds with no notice to you. Your data outlives your trip by a long margin.
An eSIM India plan from ZILLA skips all of it. You install a data profile before you land. No store visit, no passport scan, no account, no Aadhaar, no KYC. Pay with crypto and the transaction stays private by design. No bank statement naming the country you visited, no telco logging your ID against a number.
You ride the same Indian 4G and 5G networks, but you're not the subscriber in the database. For a 7-30 day trip, 5-15GB of data covers maps, rideshare, and messaging without overbuying. Your eSIM activates the moment you touch down. No hunting for a counter that's open, no wrestling with a registration portal in an unfamiliar language.
Three carriers, one country, zero patience for paperwork. ZILLA just connects you.
