Heading to Bali in 2026? Discover crucial preparation tips including recommended vaccinations, updated visa procedures, and top eSIM/SIM card choices for a worry-free journey.
Hey fellow adventurers! Just like in 2025, I'm gearing up for another amazing Bali escape this year, 2026. As someone who loves to plan every detail, I'm here to share my ultimate guide to preparing for your Bali trip.
Bali Travel Prep: Essential Tips
Bali eSIM/SIM Recommendations

Vaccinations – Prepare 6 Months in Advance!
Before any international trip, you can often get travel vaccinations for free or at a low cost through your local health services or travel clinics. Many people don't realize this!
My biggest concerns for a Bali trip are always Bali Belly and Dengue Fever. Getting sick on vacation can seriously derail your plans and make you feel bad for your travel companions. I'm usually very careful, but since my immunity isn't the strongest, I make sure to get all preventative measures done. So, I got my vaccinations well in advance.
Vaccinations (6 months in advance) – Check Your Local Health Benefits!
Vaccinations for Bali Belly and various infectious diseases can often be covered or discounted by your local health department or travel clinics. Be sure to check what benefits are available in your area. If you have a weaker immune system, I highly recommend getting vaccinated beforehand.
Beyond Bali Belly, Typhoid, Dengue Fever, and Measles, Rabies is also a concern in Bali, so it's worth considering.
While support varies by local health department, vaccinations for Hepatitis B and Typhoid can often be administered for free or for around ~$4. So, I highly recommend checking with your local health department to get these affordable vaccinations before traveling abroad.
In 2025, I received vaccinations for Hepatitis B, Hepatitis A, and Measles before my trip. I got Hepatitis A and Measles at a local clinic. I considered Tetanus but decided against it as my travel plans weren't very activity-heavy.
Entry Visa Preparation
Visa and Declaration Items Before Entry
The system changed on September 1, 2025. Previously, there were four items:
1. Electronic e-Visa / Visa on Arrival
2. Health Pass
3. Electronic Customs Declaration
4. Tourist Tax
Now, the Health Pass + Customs Declaration have been integrated. So, you'll need to prepare these three things:
1. Electronic e-Visa / Visa on Arrival
2. Integrated Declaration QR

3. Tourist Tax

Prepare these ahead of time for a smooth arrival!
SIM/eSIM Preparation
3. SIM/eSIM Preparation
An eSIM or physical SIM card is absolutely essential for international travel. I personally prefer eSIMs over physical SIMs due to the risk of losing them.
✅ I carry an iPad + two phones
✅ As a meticulous planner, using Gojek, Grab, and Google Maps while on the go is essential
✅ Streaming OTT services and listening to music at the accommodation is a must
Because of these factors, I need ample data capacity and fast data speeds.
I've seen reviews where eSIMs sometimes malfunction or have connection errors, causing inconvenience during trips.
That's why I always buy from USIMSA, a provider widely used and highly-rated.
In 2025, I used USIMSA for both my Bali and Japan trips, and I had absolutely no data issues. I streamed YouTube, listened to music at my accommodation, used Google Maps without a hitch, and even tethered my portable devices. I bought a 2GB per day for 5 days plan, and it was perfectly sufficient for three devices.
As I'm preparing for my Bali trip again in 2026, I plan to purchase my eSIM from USIMSA. If you're also planning a Bali trip this year, make sure to prepare your eSIM/SIM in advance :)

Depending on the public health center in your area, you can get Hepatitis B and Typhoid vaccinations for free or for ~$4. You may need to get Hepatitis A and Measles vaccinations at a local clinic, so it is a good idea to check in advance.
The previously separate Health Pass and Electronic Customs Declaration have been combined into a single Unified Declaration QR code. Therefore, you currently only need to prepare three things: an e-Visa (or Visa on Arrival), the Unified Declaration QR code, and the tourist tax payment.
Purchasing a 5-day plan that provides 2GB per day is sufficient for using Google Maps and watching videos without any issues. It also provides enough data to connect via hotspot to a total of three electronic devices, such as a mobile phone and an iPad.
