eSIM for Surabaya
Surabaya is Indonesia's second-largest city, a major port and business hub in eastern Java, and the main gateway for trips to Mount Bromo and the Ijen volcano. Less touristy than Jakarta or Bali, it is a working metropolis with excellent city coverage on all networks, and Telkomsel the safest for the onward volcano routes.
An eSIM Indonesia gives you access to the same plans in Surabaya as in the rest of the country. 5 GB is generally enough for maps, messaging and social media, while video streaming and hotspot use require more data. The plans shown range from 1 to 50 GB and start at $1.90. They are fully refundable within 30 days provided the eSIM has not been used on a network at the destination. The activation link is sent by email after purchase.
Getting connected in Surabaya
Surabaya has a major international airport and is well connected by train and road across Java. An eSIM installed before you fly has you connected on arrival, skipping the biometric registration, ready to navigate the business city or arrange onward transport to the volcanoes. As Indonesia's second city it has reliable coverage throughout. Most travellers use Surabaya as a staging point for Mount Bromo or Ijen, so sort those trips while connected, as the volcanic routes thin out.

Coverage in Surabaya
As Indonesia's second-largest city and a major commercial port, Surabaya has excellent, dense coverage. The business districts, the colonial old town and Arab quarter, the major malls and the airport all carry strong 4G with some 5G on all networks. It is a working metropolis rather than a tourist city, and coverage is consistent throughout the urban area with no dead zones. The connectivity to plan for is onward: Surabaya is the main gateway to Mount Bromo, around three hours southeast, and the Ijen volcano further east, and these volcanic routes and the highland approaches thin out, where Telkomsel is the safest network.
