Best eSIM for Swiss Travellers Going to Southeast Asia and Bali
Southeast Asia is one of the most popular long-haul destinations for Swiss travellers — and one of the easiest places to get hit with a large roaming bill if you are not prepared. Swisscom and Sunrise charge CHF 10 to 15 per day to use your phone in Indonesia, Thailand, and Vietnam. On a two-week trip to Bali or a month travelling through Southeast Asia, that adds up to CHF 140 to 420 in roaming fees. An AloOui eSIM gives you full 4G connectivity from the moment you land, at a fraction of the cost. No store visit, no ID, no SIM swapping.

Every major Swiss carrier charges a daily fee to use your phone in Indonesia and across Southeast Asia. As a Swiss resident, you are not protected by EU roaming regulations — the same high rates apply whether you are in Paris or Bali.
| Carrier | Bali / Indonesia Daily Charge | 7-Day Trip Cost | 14-Day Trip Cost |
|---|---|---|---|
| Swisscom | CHF 10–15/day | CHF 70–105 | CHF 140–210 |
| Salt | CHF 8–12/day | CHF 56–84 | CHF 112–168 |
| Sunrise | CHF 10–15/day | CHF 70–105 | CHF 140–210 |
| AloOui Indonesia eSIM | From $5.14 for 7 days | From $5.14 | From $10.28 |

Why You Need Reliable Data in Bali and Southeast Asia
Gojek and Grab are the primary way to get around Bali and major Southeast Asian cities — both require a live data connection to book rides. Without data, you are relying on negotiated taxi fares which are significantly more expensive.
Bali's roads between Seminyak, Canggu, Ubud, and Uluwatu are complex and poorly signposted. Google Maps with a live data connection is essential for navigating between areas, especially on a scooter.
WhatsApp calls and messages over your AloOui data keep you connected with family and friends back in Switzerland at no extra cost — far cheaper than international call rates from Swisscom or Sunrise.
Canggu is one of the world's top digital nomad hubs. Swiss remote workers and freelancers use AloOui's unlimited plans with hotspot sharing to stay productive from co-working spaces and villas.
