Best Data Plan in Bali 2025: eSIM vs Local SIM — My 3-Month Test

## TL;DR

✅ eSIM (Airalo, Telkomsel) wins on convenience — no SIM tray hunting, instant activation, works across SEA
✅ Local SIM (Telkomsel Simpati) wins on cost for stays of 30+ days
⚠️ Nusa Penida coverage is weak on both — plan accordingly

## Three Months, Two Approaches

I’ve spent about 14 months total in Bali across several long stays since 2022. For my most recent 3-month stay — Canggu for 6 weeks, Ubud for 5 weeks, Amed and Nusa Penida for the remainder — I deliberately split the test: first month on Airalo eSIM, second month on a local Telkomsel Simpati SIM from an Alfamart, third month back on Airalo.

Here is what I found.

## Cost Comparison: eSIM vs Local SIM in Bali

### eSIM (Airalo, Telkomsel network)
– 5GB / 30 days: $12
– 10GB / 30 days: $20
– 20GB / 30 days: $35

### Local SIM (Telkomsel Simpati, Alfamart)
– SIM card: 10,000-20,000 IDR (~$0.60-1.30)
– 15GB bundle / 30 days: ~80,000 IDR (~$5)
– 30GB bundle / 30 days: ~130,000 IDR (~$8)
– 50GB bundle / 30 days: ~180,000 IDR (~$11)

**The cost difference is significant.** For 30GB, you are looking at $8 local vs $35 eSIM. That is a massive gap.

## But Cost Is Not the Whole Story

Here is why I still recommend eSIM for most Bali visitors despite the price premium:

**1. Activation complexity.** Buying a local SIM in Bali technically requires passport registration. Many shops skip this, but you occasionally get a SIM that stops working after a week because it was never properly registered. This happened to two friends on my last trip.

**2. English navigation.** The Telkomsel app and top-up codes are in Indonesian. If you do not speak Bahasa Indonesia, navigating the top-up process is annoying. Airalo’s app is clean English.

**3. Time cost.** Finding a reliable shop, activating the SIM, loading the right bundle — this takes 30-90 minutes. Do you want to spend that time at the beach?

**4. Multi-country travel.** If Bali is one stop on a longer SEA trip, a local Indonesian SIM is useless in Thailand or Vietnam. An Airalo regional plan covers your whole trip.

## Speed Comparison: Same Network, Similar Speeds

Both Airalo eSIM and local Telkomsel Simpati use the same towers. The speeds I recorded were nearly identical:

**Nusa Penida note:** Coverage on the island is genuinely poor regardless of what you use. Bring downloaded offline maps and accept that video calls will be unreliable. The scenery more than compensates.

—

## My Honest Recommendation

**Stay 1-4 weeks or multi-country trip:** Get Airalo. The convenience premium is worth it.

**Stay 1-3 months, Indonesia only, comfortable with Indonesian apps:** Get a local Telkomsel Simpati SIM. Save $25-50 per month, same speeds.

**Stay 3+ months, serious nomad setup:** Get the local SIM for daily data, keep an Airalo plan as emergency backup.

Wherever you land, the Telkomsel network is what matters in Bali. Make sure whatever plan you buy uses Telkomsel — it has the best infrastructure by a significant margin over XL Axiata and Indosat.
