Short answer
No — you don't need to change your WhatsApp number when using a BaliSIM eSIM in Bali. Your WhatsApp stays connected to your home number while BaliSIM provides fast Indonesian mobile data and a local +62 number for apps like Gojek, Grab, and GoPay.
One of the most common questions we get from travelers setting up their BaliSIM eSIM: "Do I need to change my WhatsApp number to an Indonesian one?"
The short answer is no — and you shouldn't. Here's what actually happens and how to use your local Indonesian number smartly without touching your existing WhatsApp account.
Your WhatsApp Account Stays Exactly as It Is
WhatsApp is tied to your home phone number — and that number continues to work normally in Bali on your home SIM. On a dual-SIM phone with BaliSIM installed as your data eSIM, WhatsApp runs over Indonesian mobile data (fast, local) while still being registered to your original number. Nothing changes. Your chats, contacts, and call history are all intact.
This is how the vast majority of BaliSIM customers use WhatsApp in Bali: home number for the account, Indonesian data for the connection. It's faster than roaming and cheaper than using your home carrier's international data.
So What Is the Indonesian Number Actually For?
Your BaliSIM eSIM comes with a local +62 Indonesian number included. You don't need it for WhatsApp — but you do need it for almost everything else in Bali that requires local verification:
- Gojek — requires a +62 number to create an account and receive the SMS OTP. Without this, you cannot book rides or food in Bali.
- Grab — same requirement. Your existing Grab account from home might work, but new accounts or re-verification requires a local number.
- GoFood / ShopeeFood — food delivery apps used heavily by locals and travelers in Bali both require Indonesian number verification.
- GoPay / OVO — Indonesia's e-wallet apps for cashless payments at local warungs, markets, and smaller vendors. Requires +62 to register.
- Local accommodation or tour operators — many smaller Bali businesses only communicate via WhatsApp, and some prefer replying to local numbers. Having a +62 number can make communication smoother.

Can You Create a Second WhatsApp Account with the Indonesian Number?
Yes — if you want to. WhatsApp supports dual accounts on most modern Android phones (Samsung, Pixel, Xiaomi) and on iPhone via the Dual SIM feature since iOS 16. You can run your home number WhatsApp and a separate Indonesian number WhatsApp simultaneously.
Most travelers don't bother — it adds complexity without much benefit for a short trip. But if you're staying in Bali for a month or more, running a business, or dealing heavily with local vendors, a secondary Indonesian WhatsApp can be useful.
To set it up on iPhone: Settings → Phone → choose your BaliSIM eSIM as the second line → then add the account in WhatsApp settings. On Android: use the built-in Dual Apps or Parallel Space feature if available on your device.
The Setup That Actually Works for Most Travelers
Keep your existing WhatsApp on your home number. Use your BaliSIM Indonesian number (+62) to verify Gojek, Grab, and GoPay when you arrive. Set BaliSIM as your mobile data line so WhatsApp and all other apps run on fast local Indonesian data. Done.

Yes. Your WhatsApp account stays linked to your original home number unless you manually change it inside WhatsApp settings. Friends, family, and work contacts will continue messaging your normal number exactly as before.
Do I need an Indonesian number for Gojek and Grab?
Usually yes. Most travelers use the Indonesian +62 number included with BaliSIM to register or verify Gojek, Grab, GoFood, and local services in Bali. This makes ride-hailing and food delivery setup much smoother after arrival.
Can I have two WhatsApp accounts on one phone?
Yes. Most modern iPhones and Android phones support dual WhatsApp accounts when using dual SIM or eSIM. You can keep your main WhatsApp on your home number and create a second WhatsApp account using your Indonesian BaliSIM number if needed.
