Coverage and network
Coverage across East Java
Indonesia mobile networks
Surabaya is Indonesia's second city and a working port rather than a tourist one, which shows in the network: solid, business-grade coverage across the centre and the industrial belt, without the 5G density Jakarta has. East Java beyond it is a mix.

Surabaya, specifically
- Tunjungan, Gubeng, Darmo: Reliable 4G with 5G in parts. The malls and business districts are well covered.
- The port and Kalimas: Tanjung Perak and the old port area are covered. Worth knowing if you are catching a Pelni ferry, where departure information is unreliable and being online helps.
- The Suramadu bridge to Madura: Holds signal across the whole 5.4 km span. Madura itself is covered in Bangkalan and the main towns and gets patchy in the island's interior and out towards Sumenep.
- Mount Bromo, three hours southeast: Cemoro Lawang village at the crater rim has service. Down on the sand sea and on the pre-dawn jeep run there are gaps, and the viewpoints vary. Download the route the night before.
- Heat and afternoon storms: Surabaya is one of the hotter Indonesian cities and the wet-season storms are heavy. Phones throttle in the heat before the network does.
All of Indonesia
The plan covers the whole country, so Surabaya, Bromo, Bali and anywhere further east run on the same eSIM.

Arriving in Surabaya
Your flight lands in Sidoarjo
Juanda is called Surabaya's airport but sits in Sedati, in neighbouring Sidoarjo regency, about 12 km out. Free Wi-Fi runs in the terminals. The drive into the city is where you will actually want data.

Frequently asked questions
Where to buy a SIM card in Surabaya?
GraPARI and operator outlets in Tunjungan Plaza and Pakuwon, plus counters at Juanda. Buy from an official outlet rather than a stall - a SIM that is not registered properly will stop working, and the airport is in a different regency from the city if you need to go back.
Do I need to register anything to use a phone here?
For a local SIM, two things: your passport at the counter, and your handset on Indonesia's IMEI register - an unregistered phone loses local service within hours. A roaming eSIM sits outside both, because it carries no Indonesian number and Customs counts it as inbound roaming.
Is there signal at Mount Bromo?
In Cemoro Lawang, yes. Out on the sand sea and during the 3am jeep run to the viewpoints it comes and goes, and the crater rim itself is inconsistent. Save your map and your driver's number before you leave Surabaya - the trip starts long before dawn and sorting anything out at that hour is grim.
eSIM not working in Surabaya?
Up at Bromo or inland on Madura, gaps are genuine. In the city, check the phone is drawing data from the Ohayu line with roaming enabled, then cycle Airplane mode. Chat and support@ohayu.com are open 24/7.
