Bali eSIM for UK travellers

What roaming from the UK actually costs

Depending on your network, Indonesia roaming means either a daily pass (commonly around £5–8 per day for a capped allowance) or out-of-bundle rates that can run to pounds per megabyte — check your carrier’s Indonesia page before you fly. Over a two-week Bali trip, day passes alone can exceed £70–100. A local eSIM for the whole trip costs a fraction of that, with more data at local network speeds.

And roaming keeps your +44 number — so Gojek and Grab (Bali’s Uber-equivalents) struggle to verify you. A real +62 number fixes that on day one.

Practical bits for the long haul

• Order before the 16+ hour journey — complete the 5-minute ID check at home; it’s reviewed within 1–2 hours, 24/7, so your QR is installed before Heathrow or Manchester.
• Keep your UK SIM in for banking SMS — the eSIM runs alongside it (roaming data off, SIM on).
• Prices display in GBP if your browser locale is UK; the actual charge is in IDR and your bank converts it — most UK cards do this at close to the real exchange rate.
• Plugs: Bali uses European two-round-pin sockets (types C/F, 230V) — pack an adapter for your type G plugs.
