eSIM Travel Tips for Indonesia
Install your eSIM before your flight to Bali
Bali is one of the most popular long-haul destinations for British travellers. Set up your HelloRoam eSIM at home before departure. Enable data when you land at Ngurah Rai and you are connected immediately. No Telkomsel SIM card queue in the arrivals hall.
Currency in Indonesia
Indonesia uses the Indonesian rupiah (IDR), and prices for everyday items run into the tens of thousands of rupiah, so do not be alarmed by the zeros. Indonesia is good value for British visitors, especially for accommodation, food, and motorbike hire. Keep your HelloRoam eSIM active for banking apps and locating ATMs in tourist areas.
Coverage across Bali
Bali has strong 4G coverage across Seminyak, Kuta, Canggu, Ubud, Sanur, Jimbaran, and Nusa Dua. The Tegalalang rice terraces area and Munduk in the highlands have reasonable signal. Very remote temple areas and forest walks on the slopes of Mount Agung can have weaker coverage.
Lombok and the Gili Islands
Lombok has 4G in Mataram and main coastal resort areas. The Gili Islands (Gili Trawangan, Gili Meno, Gili Air) have limited signal, Gili T has the best coverage. Mount Rinjani trekkers should download all offline maps before starting as coverage is very limited above the treeline.
FCDO travel advice for Indonesia

£3.73–£18.64 total
Telkomsel and XL SIM cards are available at Indonesian airports and Alfamart/Indomaret convenience stores. They require passport registration and physical SIM-swapping. Local SIMs are cheap but involve arrival hassle.
£3.73–£11.19/day
UK networks treat Indonesia as a rest-of-world destination, so EE, Vodafone UK, O2, and Three charge daily international rates or require add-ons. Over a month in Bali those daily charges build up quickly on your phone bill. HelloRoam gives a predictable cost.

Best time to visit Indonesia from the UK
Indonesia is warm year-round at 26°C to 32°C but the dry and wet season varies by region. Bali's dry season runs April to October, and this is the best time to visit, with clear skies and low humidity. Bali's wet season (November to March) brings daily afternoon rain but is still very popular with British visitors and prices are lower. Lombok and the Gili Islands are also best April to October. Yogyakarta and Borobudur are relatively pleasant year-round. British school holidays in July and August are peak season for Bali.
