Which Networks Do eSIMs Connect To?

Singapore Networks

Singapore has three carriers, all offering nationwide 5G coverage across the island.

Singtel is the largest with the most extensive infrastructure. It provides consistent 5G across the entire island and averages 200-500 Mbps on 5G and 50-100 Mbps on 4G. Singtel is the default choice for most eSIM plans.

StarHub offers comparable coverage with strong performance in the CBD, Orchard Road, and residential areas. 5G coverage is nearly island-wide.

M1 (Keppel) provides full island coverage with competitive speeds. Its 5G network shares infrastructure with StarHub under the ANTINA joint venture.

Singapore has among the fastest mobile internet in the world. Any network will exceed your needs.

Malaysia Networks

Malaysia has three major carriers with varying coverage strengths.

Maxis has the strongest overall coverage and the most extensive 5G rollout. It covers KL, Penang, Johor Bahru, and most of Peninsular Malaysia with 4G/LTE. Sabah and Sarawak (Malaysian Borneo) coverage is available in major cities. Maxis is the best all-round choice.

Celcom (now merged with Digi as CelcomDigi) provides wide coverage across Peninsular Malaysia and is particularly strong in rural areas. The Celcom-Digi merger in 2022 created Malaysia’s largest network by subscriber count, and ongoing integration has improved coverage in previously underserved areas.

Digi (CelcomDigi) has strong urban coverage and competitive pricing. Post-merger, Digi subscribers benefit from expanded rural reach.

How Does Cross-Border Johor-Singapore Travel Work with eSIM?

The Johor Bahru (Malaysia) to Singapore corridor is one of the busiest land borders in the world. Thousands of travelers cross daily via the Causeway or Second Link.

The Problem with Single-Country eSIMs

If you have a Singapore-only eSIM, it stops working when you cross into Johor. A Malaysia-only eSIM stops working when you return to Singapore. Switching eSIM profiles at the immigration checkpoint is impractical — you are on a bus or in a car, processing through border control.

The Solution: Regional eSIM

A regional Southeast Asia eSIM covers both countries on a single plan. Your phone automatically connects to the best local network on each side of the border. No manual switching, no data interruption.

The regional plan costs the same as two separate minimum plans and provides a single shared data pool with automatic switching.
