Mobile Plans with Data Roaming in Singapore
If you travel often to Malaysia, Indonesia, or elsewhere in the region, buying a separate travel SIM or eSIM for every trip gets old fast. Many Singapore mobile plans now include roaming data as part of the monthly fee, so you can cross the border and keep using your regular number.
This page shows plans that include roaming data. The amount varies widely, from 1GB to over 600GB depending on the plan and destination.
What's Usually Included
Most plans split roaming into tiers:
Malaysia and Indonesia get the most generous allowances. Some plans let you use your full local data in these countries. SIMBA, for example, includes Malaysia data as part of your regular allowance on most plans.
APAC destinations typically cover Malaysia, Indonesia, Thailand, Vietnam, Taiwan, and sometimes India, Bangladesh, Hong Kong, and South Korea. Expect 2-20GB depending on the plan.
International/Worldwide covers 50-60+ countries including Japan, Korea, Australia, Europe, and the US. Allowances are smaller here, usually 1-8GB.
The exact country list differs by provider. Check the fine print before assuming your destination is covered.
Providers with Strong Roaming
SIMBA stands out for regional travel. Their local data works in Singapore, Malaysia, Indonesia, Thailand, and Hong Kong (on higher plans). They also include 3-15GB for 60+ other countries.
Eight includes 10GB APAC roaming (Malaysia, Indonesia, Thailand, Vietnam, India, Taiwan) plus 2-8GB international roaming across 58 countries on most plans.
CMLink is worth considering if you travel to mainland China frequently. Their plans include shared data across Singapore, China, and Hong Kong.
VIVIFI and Zero1 both offer plans with 100-600GB of Malaysia roaming data valid for 365 days, which works well for frequent JB trips.
GOMO offers unlimited roaming plans (with fair usage limits) covering 50 destinations for $35-50/month if you need heavy overseas usage.
Things to Check
Voice calls while roaming are often not included, even when data is. Some plans support VoLTE roaming (calls over data), others don't. If you need to make calls abroad, verify this before signing up.
Hotspot/tethering may be blocked on roaming data with some providers.
Speed caps apply to some roaming allowances. You might get full speed locally but reduced speeds abroad.
Validity periods matter for bonus roaming data. Some plans offer 100-600GB Malaysia data, but it expires after 90 or 365 days.
FAQ
Do I need to activate roaming before travelling? Usually yes. Most providers require you to enable data roaming in your phone settings. Some also need you to toggle a roaming setting in their app.
What happens when I use up my roaming data? Depends on the provider. Some cut you off, others throttle speeds, and some charge pay-per-use rates. Check your plan terms.
Can I buy more roaming data if I run out? Most providers sell roaming add-ons. Prices range from $3-10 per GB depending on the destination.
Is roaming data slower than local data? Sometimes. You're connecting to a foreign network, so speeds depend on their infrastructure and your provider's agreement with them.
