Tourist attractions and suburbs
• The main attractions have basic coverage, but the signal is unstable in remote areas.
- Sentosa Island (Singapore): Full 4G/5G coverage across the island with stable signals in Universal Studios and beach areas, but no signal in underwater zones.
- Genting Highlands (Malaysia): The mountaintop resort offers stable 4G coverage, with intermittent signals on mountain roads and only 2G service in some curved areas.

- Redang Island (Malaysia): The resort area has good 4G coverage, underwater signals are unavailable in diving areas, and the northern part of the island has weaker signals.
- Mount Kinabalu (Sabah): 4G coverage at the starting point, signal gradually weakens during the climb, no stable signal in areas above 2,000 meters in altitude.
- Singapore Zoo and Night Safari: The main pathways in the park have continuous 4G coverage, but signal strength decreases in the rainforest areas. It is recommended to download maps in advance.
- Malacca Strait Cruise: Nearshore areas have good 4G coverage, but the signal becomes unstable beyond 5 kilometers offshore.
- Cameron Highlands (Malaysia): Tea plantation areas have 4G coverage, intermittent signals in valley regions, and some viewpoints offer only 3G service.
- East Malaysia Rainforest Area: Main roads have 4G coverage, but alternative communication solutions are required for deep rainforest exploration; carrying a satellite phone is recommended.

Network Usage Tips
cross-border frontier region
There may be network switching delays on the Johor–Singapore Causeway (Singapore-Malaysia border). It is recommended to manually select the network in advance, and some carriers offer cross-border data plan services.
Mountains and Rainforests
Signal reception is unstable in areas such as Mount Kinabalu, Cameron Highlands, and the rainforest regions of East Malaysia. It is recommended to download offline maps before departure. Although Malaysia's 4G/5G network availability reaches 97.9%, terrain has a significant impact.
Indoor and underground areas
Some buildings and MRT lines in Singapore may experience weak 4G signals. It is recommended to use the network near windows or in open areas when in low-signal zones.
5G coverage limitations
Singapore's 5G network coverage has exceeded 80%, but only devices compatible with the relevant frequency bands can access it, as some older phones only support 4G networks. In Malaysia, 5G coverage is primarily concentrated in urban areas.
Network Congestion Alert
During holidays such as Singapore's National Day and Malaysia's Hari Raya, network congestion may occur around popular tourist spots, so it is advisable to avoid using high-bandwidth applications during peak hours. Malaysia has seen rapid growth in 5G users, but resource allocation remains uneven.
Power supply issues
Some areas in East Malaysia experience unstable power supply, which may affect the operation of base stations. It is recommended to download necessary materials in places with stable electricity, such as hotels or tourist centers.
Language support issues
In some parts of Malaysia, Malay is predominantly spoken, and English support is limited. It is advisable to download a translation app in advance, especially when traveling to remote areas in East Malaysia.
Battery Consumption Warning
In areas with weak signals, mobile phones continuously search for networks, leading to faster battery drain. It is recommended to carry a portable charging device. The mobile network population coverage in Singapore and Malaysia reaches 100% and 98.6% respectively, but signal instability may still occur in certain localized areas.
Price Evaluation
Singapore and Malaysia's urban areas boast over 90% 4G/5G coverage, but a significant gap exists between West Malaysia (95% 4G coverage) and East Malaysia (only 75%). Mobile data prices in both countries have dropped by approximately 50% since 2015. In urban areas, basic packages (500MB-2GB/day) suffice for daily needs, while trips to East Malaysia's rainforests or mountainous regions require packages exceeding 2GB/day for uninterrupted usage. According to the latest data, Malaysia's 5G coverage has reached 82.4% of populated areas, with Singapore leading the region in 5G network experience—though signal strength may weaken inside certain buildings. For short-term travel, economical packages (500MB-1GB/day) are advisable, while in-depth exploration or visits to remote areas warrant packages exceeding 2GB/day or those with larger total data allowances.
