Bali and Indonesia are dream destinations. Between Ubud’s rice terraces, Seminyak’s beaches, Lombok’s temples, and diving around the Gili Islands, your smartphone is essential: Grab for transport, Google Maps for winding roads, and social apps for sharing photos.
Why choose an eSIM for Bali / Indonesia?
Indonesia is outside the EU. French roaming typically costs €5–10 per MB. For 1 GB you could theoretically pay thousands of euros. eSIM solves this.
eSIM vs local SIM in Bali
| Factor | eSIM | Telkomsel SIM (airport) |
|---|---|---|

| Buying | Before departure | Queue at Ngurah Rai |
| Activation | Instant | 10–20 minutes + passport |

eSIM is price-competitive with a local Bali SIM and far more convenient.
