Bali Travel Guide 2026: eSIM, Visa & Vaccine Checklist

Essential Bali Travel Tips / Recommended eSIMs & Discount Links / Entry Requirements

By_2jay

Here is a complete, hyper-organized checklist for your upcoming Bali adventure!

As an absolute Type-A planner, I live for spreadsheets, price comparisons, and stress-free travel.

Whenever my friends or family plan a trip, they leave the details to me.

I compile Excel sheets comparing accommodations, find the best credit card discounts, and map out daily routes.

I even planned my sibling's entire honeymoon from scratch!

Since I prefer smooth, hassle-free journeys, I've put together the ultimate preparation guide for Bali based on my own experience.

I started drafting this checklist six months before departure, right after booking my flights.

While I have a separate list for daily packing items, these are the crucial things you need to secure well in advance.

1. Vaccines (6 Months Before) – Save Money at Local Health Centers!

When preparing for Bali, my biggest worries were "Bali Belly," infectious diseases, and local sanitation.

Getting sick abroad ruins your entire itinerary and is incredibly stressful.

My personal philosophy is to prevent whatever can be prevented, especially since my immune system can be sensitive.

So, I made sure to get all my recommended shots before leaving.

Aside from Bali Belly, typhoid, dengue fever, and measles, rabies has also been a growing concern in Bali recently.

Depending on where you live, local public health clinics offer incredible rates.

Vaccines like Hepatitis B and Typhoid can be done at community health centers for free or for as little as ~$4.

I highly recommend checking your local health department's offerings to save money before heading overseas!

I ended up getting vaccinated for Hepatitis A, Hepatitis B, and MMR (Measles, Mumps, and Rubella) before my flight.

I did Hepatitis A and MMR at a local private clinic.

I debated getting a tetanus shot, but since my itinerary didn't include any extreme outdoor activities, I decided to skip it.

2. Pre-Entry Visas and Mandatory Declarations

Indonesia updated its entry declaration system recently.

Previously, travelers had to handle four separate items:

1. e-VOA (Electronic Visa on Arrival)

2. Health Pass

3. Electronic Customs Declaration (ECD)

4. Bali Tourist Levy

Now, the Health Pass and the Customs Declaration have been integrated into a single, unified portal!

To keep your arrival seamless, prepare these three things before you fly:

1. Electronic Visa on Arrival (e-VOA)

2. Integrated Declaration QR (Health + Customs)

3. Bali Tourist Levy

Have these QR codes saved on your phone, and you will breeze through Denpasar Airport!

3. eSIM vs. Physical SIM Card

Securing your internet connection before you land is an absolute must.

Personally, I try to avoid physical SIM cards because of the risk of losing my original SIM card.

I've actually had my pocket picked while traveling before, so keeping my physical SIM safely locked inside my phone is a priority.

That is why I always opt for eSIMs.

Data speed and hotspot capabilities are also crucial for me since I travel with my iPad.

I need a fast, reliable connection that handles tethering without any lag.

After comparing several options for my Bali trip, I went with the "Usimsa eSIM" because of its great reviews and competitive pricing.

I chose the 2GB/day plan for 5 days (perfect for a 4-night, 6-day itinerary).

Since I tether my iPad constantly, 2GB per day gave me plenty of breathing room.

If you are traveling with a partner, one of you can get the 2GB plan while the other goes with a slightly lighter data option to save money.

"How to Set Up Your Usimsa eSIM"

I connected my iPad via personal hotspot and had zero issues.

I watched YouTube videos during meals, streamed music poolside, and enjoyed seamless, high-speed connection the entire time.

One quick tip: make sure to download and set up ride-hailing apps like Grab and Gojek before leaving home.

It is much easier to verify your phone number and link your credit cards while you are still in your home country!
