Airport SIM cards typically cost $5-15 for 5-20GB / 15-30 days. We measured 10-20 min; IMEI check may add time for purchase and activation at the counter. An eSIM activates in under 2 minutes from your phone, with zero wait and no counter visit.
Local prepaid SIMs in Indonesia run $3-8 for 5-15GB / 30 days. Our top-ranked eSIM provider offers $0.84/GB, which undercuts most prepaid counters on a per-gigabyte basis. The eSIM also saves you from ID registration lines and store visits that eat into your first day.
Our comparison note: IMEI registration makes local SIM activation more complex for tourists. eSIM completely bypasses this regulatory hurdle..
