[IMAGE:flat-design-batam-bintan-singapore-indonesia-islands-esim-connectivity-illustration]
Batam and Bintan sit in Indonesia’s Riau Islands province, just across the Strait of Singapore. Batam is a manufacturing and commercial island with ferry terminals and duty-free shopping. Bintan is more resort-oriented — golf courses, beach resorts, and the local town of Tanjung Pinang.
### The eSIM Transition at Singapore → Indonesia
This is one of Southeast Asia’s most frequent international eSIM transitions — Singaporeans and Singapore visitors crossing for a weekend:
– **At Singapore’s Harbourfront Ferry Terminal**: Singapore eSIM (or SEA regional plan on Singapore) — excellent 4G
– **On the ferry** (45–60 minute crossing): Coverage drops mid-strait; both Singapore and Indonesian networks visible from different sides
– **Arriving at Batam/Bintan**: Indonesian network activates — Telkomsel, XL, or Indosat
If you have a **Southeast Asia regional plan**, this transition is automatic — no action needed.
If you have a **Singapore-only eSIM**: You’ll need a separate Indonesia plan. Either buy it before departure (Airalo) or purchase locally in Batam/Bintan’s ferry terminal.
### Batam Coverage
**Batam Centre ferry terminal**: Excellent 4G immediately upon arrival.
**Nagoya Hill** (shopping area): Excellent 4G.
**Waterfront area**: Good 4G.
**Golf courses**: Good 3G–4G throughout.
Batam is a developed industrial island — connectivity is solid throughout the main areas.

### Bintan Coverage
**Bandar Bentan Telani terminal** (resort ferry terminal, northern Bintan): Good 4G.
**Bintan Lagoon Resort area**: Good 4G.
**Tanjung Pinang** (local town, southern Bintan): Good 4G. Authentic Indonesian town; not a resort.
**Trikora Beach** (east coast): 3G–4G.
Bintan’s resort strip (north) and the main town (south) are both well-covered.
### Practical Tips
**Different ferries for different destinations**:
– Singapore → Batam: Multiple operators from Harbourfront (12–15 crossings/day)
– Singapore → Bintan Resort (Lagoi): Bintan Resort Ferries from Tanah Merah Ferry Terminal
– Singapore → Tanjung Pinang: Multiple operators from Harbourfront
Book via FerryBooking.com or operator websites with Singapore eSIM active before departure.
**Customs and SIM cards**: Both islands have Indonesia customs. Local SIM cards available in Batam Centre terminal if you prefer a physical Indonesian SIM.
