Bali after the flight: data, cover, transfers and the things that sell out.

Indonesia's mobile market is well built — Telkomsel has the deepest reach, with Indosat Ooredoo Hutchison and XL Axiata competitive in the south of Bali — and buying a local prepaid SIM in a Kuta phone shop takes minutes. The complication is not the SIM. Indonesia operates an IMEI registration regime under which handsets brought into the country and used on Indonesian networks are expected to be registered with customs, and unregistered devices can lose local network service after an initial window. This trips up long-stay visitors far more often than short ones, but it is the reason a lot of experienced Bali travellers no longer bother with a local physical SIM.

An eSIM sidesteps the SIM-shop entirely and is the cleanest option for a normal holiday. Activate it in India, land with data already working, and keep your Indian profile live for banking and airline OTPs. Because the rules that attach to hardware can and do change, check the current customs position rather than assuming any product is exempt — the honest position is that this is a customs question with a customs answer, not a marketing one.

International roaming from an Indian operator is the third route and the least admin. It costs more per day than a local plan, and for a week in Bali the difference is usually smaller than people expect once the value of not queueing anywhere is counted.

Coverage in the south — Kuta, Seminyak, Canggu, Sanur, Uluwatu — and around Ubud is solid. It degrades on the Nusa islands, on the fast-boat crossings, in the rice-terrace interior around Sidemen and Munduk, and on the Gili crossing if you continue to Lombok. Anyone planning a Nusa Penida day trip should download offline maps, because that island's roads are exactly where you will want them.

A standard international travel policy covers emergency medical treatment, hospitalisation and evacuation, trip cancellation and curtailment, delays, and baggage. In Bali the medical side is used far more than anywhere else Indian travellers go casually, and the reason is uniform: two-wheelers. Scooters are the default way to move around Canggu, Ubud and Uluwatu, the roads are busy and uneven, and road-rash injuries are routine enough that Bali's private clinics are visibly organised around treating them.

This is where policies bite. Most travel insurance either excludes motorcycle and scooter riding outright or covers it only if you hold a licence valid for that vehicle class and an International Driving Permit, and only if you were wearing a helmet. Riding on a licence you do not hold is the single most reliable way to convert a covered accident into an uncovered bill. If you plan to ride, sort the licence and the endorsement in India, and read the clause word for word.

The second Bali-specific exposure is disruption rather than injury. Bali sits among active volcanoes, and ash events have closed Ngurah Rai to traffic before. Cover for trip curtailment, missed onward connections and additional accommodation is what turns that from a financial problem into an inconvenience — particularly if your Bali flight and your onward flight are on separate tickets. Divers should also check depth limits and whether the policy funds hyperbaric treatment, which is not something the island has in abundance.

Indonesia does not present travel insurance to Indian visitors the way Schengen states do at the visa stage, but entry conditions are the government's to change. Confirm the current position with Indonesian immigration rather than assuming, and never treat any policy as pre-accepted by an authority.

Ngurah Rai is unusual for a major holiday airport in that it is genuinely inside the resort area. Kuta, Legian, Seminyak and Jimbaran are short hops. Everything else is not, and Bali's traffic is the reason. Ubud is a long drive that gets substantially longer in the late afternoon; Canggu is close as the crow flies and slow in practice because of the road network; Amed, Lovina and the east coast are half-day journeys.

From the terminal you can use the official airport taxi counters, a pre-booked private transfer, or app-based ride-hailing — with the caveat that pickup arrangements at the airport and in certain villages have been contested by local transport cooperatives, and the rules differ by area. A pre-booked transfer with a named driver removes the argument, which is worth something at the end of an overnight flight.

If Bali is the first stop rather than the whole trip, plan the onward legs deliberately. Fast boats to Nusa Penida and Nusa Lembongan leave from Sanur, and services to the Gilis and Lombok run from Padangbai and Serangan. Sea conditions cancel crossings, so leaving a buffer before an international flight home is not paranoia.

Bali's restaurants, spas and surf lessons need no notice. Its capped, timed and boat-dependent experiences do, and those are the ones people remember. The pattern to internalise is that anything with a sunrise, a boat or a permit attached should be handled before you arrive.

There is also a Bali-specific administrative step worth knowing about: the province levies a tourist contribution on foreign visitors, payable online through the official provincial channel. Amounts and enforcement have changed since it was introduced, so check the official Love Bali portal rather than a third-party reseller, and keep the confirmation on your phone.

Indonesia offers visa on arrival to a defined list of nationalities at designated air and sea ports, and also runs an electronic version applied for before travel. Indian passport holders have been inside that framework, and the practical questions — which ports accept it, how long it is valid, whether it can be extended and how — are the ones that change. The electronic route is worth considering purely because it removes an arrival queue.

Indonesia also requires an electronic customs declaration from arriving passengers, completed shortly before landing and presented as a code at the customs channel. It is quick, it is free through the official channel, and it is much easier to do on the aircraft with the form saved offline than in the arrivals hall on someone else's wifi.

Verify current rules with Indonesian immigration before you book anything non-refundable. Approval to travel is not the same as admission, and the officer at the border decides.
