SIMBA's APAC roaming is one of the more talked-about features of the SuperRoam plan range — and for good reason. For Singaporeans who travel regularly across Southeast Asia and Northeast Asia, having a meaningful data allowance built into your monthly plan without separate add-ons is a genuine convenience. But the details matter: not every SIMBA plan includes APAC roaming, the pool is shared across nine countries, and the fallback pay-per-use rate kicks in faster than many users expect on longer trips. This guide covers which SIMBA plans include APAC roaming, exactly which countries are in the zone, how the data drawdown works in practice, and when it makes sense to supplement with a dedicated travel eSIM.
SIMBA, formerly known as TPG Singapore, is Singapore's fourth telco with full 4G and 5G spectrum rights. All SIMBA mobile plans come with built-in roaming for 60+ countries under Group A international roaming. APAC roaming is a separate, additional data allowance for a specific set of nine Asia-Pacific destinations, available on SuperRoam plans from SGD $10/month and above.
The nine APAC roaming countries covered by SIMBA are: Malaysia, Hong Kong, Indonesia, Taiwan, Thailand, Bangladesh, Vietnam, China, and South Korea. When you use mobile data in any of these countries, it draws from your APAC roaming bucket first — after your main data zone is consumed — before falling through to Group A or pay-per-use billing.
SIMBA's data draw-down order is: Main Data zone → APAC roaming allowance → Group A international roaming → Pay-per-use (SGD $4/GB from your SIMBA Wallet). Understanding this sequence helps you plan which allowance you're actually relying on when you land in Bangkok or Seoul.
All current SIMBA SIM-only and prepaid plans include APAC roaming. The amount of APAC data varies significantly by plan tier, so choosing the right plan for your travel frequency matters.
Note that SuperRoam39 is the top-tier SIM-only plan and also includes in-flight data roaming on select airlines. China roaming is available from SuperRoam12 and above — not on SuperRoam10. Always verify current plan details and roaming allowances on the SIMBA website or My SIMBA app before purchasing, as plan structures can be updated.
Your SIM is roam-ready by default. SIMBA SIM cards and eSIMs come with roaming pre-enabled. There's no separate roaming activation process. Enable data roaming in your device settings and you're good to go the moment you land.
Confirm your plan covers your destination. All nine APAC countries are included on SuperRoam10 and above, with the exception of China (SuperRoam12 and above only). If you're heading to South Korea, Hong Kong, or Malaysia, SuperRoam10's 12 GB APAC allowance covers it. For China, upgrade to SuperRoam12 at minimum.
Monitor your APAC balance in the My SIMBA app. The app shows your remaining APAC data allowance and your SIMBA Wallet balance in real time. Check it before departure, especially if you've made other regional trips during the same billing cycle. The APAC pool is shared across all nine countries and refreshes each 30-day cycle.
Top up your SIMBA Wallet before you travel. Once your APAC allowance runs out, billing switches to SGD $4 per GB from your SIMBA Wallet automatically. If your Wallet is empty, your data connection stops. A Wallet top-up before departure is inexpensive insurance against running dry mid-trip.
APN settings. SIMBA's APN typically configures automatically on partner networks across APAC. If data doesn't connect after landing, go to mobile data settings and check that the APN is set to "simba", or try selecting the network manually from the available carriers in your destination.
For longer regional trips, consider a dual-SIM setup. Heavy data users spending a week or more in a single APAC country may exhaust their monthly APAC allowance before returning to Singapore. A dedicated country-specific travel eSIM used alongside your SIMBA SIM keeps your Singapore number active while preserving your APAC budget for the rest of the month.
SIMBA's APAC roaming is designed for moderate, multi-destination use across the region — a few days in KL here, a long weekend in Bangkok there. Where it starts to show limits is during intensive single-destination trips. A week in Seoul using Google Maps for every commute, streaming music, and sending photos home can chew through 10–15 GB easily. On SuperRoam12, that's nearly the entire APAC allowance gone on one trip — leaving nothing for the rest of the month.
A travel eSIM gives you a fixed, dedicated data budget for a specific country or trip. It doesn't pull from your SIMBA APAC pool, which means your monthly allowance stays intact for the other regional trips in your cycle. Your SIMBA line remains active on the same device for calls and Singapore number accessibility — useful for banking OTPs and staying reachable while you're away.
This setup is also relevant for multi-country APAC itineraries. Flying Singapore → Bangkok → Seoul → Tokyo in one trip is a common route for Singaporean travellers. TurkSIM offers eSIM coverage across this entire corridor, so rather than watching your SIMBA APAC bucket drain across three stops, you have a single prepaid plan covering the full journey.
SIMBA's APAC roaming is genuinely useful for the kind of trip where you're making a few calls, navigating to a restaurant, and posting to Instagram. It becomes a liability when you're relying on mobile data the way you'd rely on a home connection — working from a hotel in Bangkok, live-streaming a concert in Seoul, or video-calling family every evening from Taipei.
The fundamental tension is that SIMBA's APAC allowance resets monthly, not per trip. Heavy use on one trip can leave you short for the next. The SGD $4/GB Wallet safety net means you're never completely offline, but it turns a predictable monthly bill into a variable one.
TurkSIM eSIMs for Asia destinations connect through local partner networks — AIS in Thailand, SK Telecom or KT in South Korea, Celcom or Maxis in Malaysia — delivering local data speeds at prepaid rates. You buy what you need for the trip, your SIMBA APAC budget stays intact, and your Singapore number remains reachable the whole time. It's a clean separation of your home plan from your travel plan, which is exactly what frequent regional travellers need.
SIMBA APAC roaming covers nine destinations: Malaysia, Hong Kong, Indonesia, Taiwan, Thailand, Bangladesh, Vietnam, China, and South Korea. All nine are included on SuperRoam12 and above. China is not included on SuperRoam10; all other eight APAC countries are included on SuperRoam10.
It ranges from 12 GB on SuperRoam10 up to 80 GB on SuperRoam25. The mid-range SuperRoam18 includes 30 GB of APAC roaming data per 30-day cycle. Check the current plan details on the SIMBA website, as allowances are updated periodically.
Once your APAC allowance is exhausted, data usage in APAC countries is charged at SGD $4 per GB from your SIMBA Wallet, billed in 10 MB increments. If your Wallet balance reaches zero, your data connection stops until you top up. This applies across all nine APAC countries.
No. Japan is not part of SIMBA's APAC roaming zone. Japan falls under Group A international roaming, which is the broader 60+ country bucket available on all SIMBA plans. Data in Japan draws from your Group A allowance, not the APAC pool.
Yes. SIMBA's prepaid plans include APAC roaming on all tiers. The amount of APAC data varies by plan — from 12 GB on the entry-level prepaid option up to larger allowances on higher tiers. The same data-draw-down order applies: main data zone, then APAC, then Group A, then pay-per-use.
Yes. SIMBA eSIMs include the same APAC roaming allowances as physical SIM plans. You can choose an eSIM option at checkout on the SIMBA website, which is available on most current SIMBA plan tiers.
Open the My SIMBA app and go to your plan details. The app shows your remaining APAC data balance, your Group A balance, and your SIMBA Wallet credit separately. It's worth checking all three before any APAC trip, particularly if you've made other regional trips earlier in the billing cycle.
