For tourists, we generally recommend Singtel or StarHub prepaid plans due to their extensive coverage and tourist-friendly packages. Both offer good data allowances and have widespread retail presence for easy top-ups. However, the best choice depends on your specific needs, duration of stay, and usage patterns.

There are multiple ways to top up in Singapore: convenience stores (7-Eleven, Cheers), operator retail stores, ATMs, mobile apps, online portals, and physical top-up cards. Digital methods are increasingly popular due to convenience and instant processing.

All major operators (Singtel, StarHub, M1) provide excellent coverage across Singapore due to the country's small size and advanced infrastructure. Singtel traditionally leads in rural and underground coverage, while differences in urban areas are minimal.

Yes, most unlocked phones work in Singapore. The country uses GSM networks with 2G, 3G, 4G, and 5G services. Check that your phone supports the frequency bands used by Singapore operators (900MHz, 1800MHz, 2100MHz for 3G and various LTE bands for 4G/5G).

Prepaid plans require payment upfront and offer more control over spending, making them ideal for tourists and budget-conscious users. Postpaid plans offer more features, better rates for heavy users, and device financing options but require credit checks and contracts.

Consider factors like coverage in areas you frequent, data allowances, international roaming options, customer service quality, and pricing. Our detailed operator comparisons help you evaluate these factors based on your specific needs and usage patterns.
