Southeast Asia mobile game distribution beyond Google Play

Direct answer — how do you distribute a mobile game in Southeast Asia beyond Google Play? You layer three channels on top of the Play Store rather than relying on it alone: OEM preloads and OEM stores (Xiaomi is back to number one across the region, and top-two in Vietnam and the Philippines), direct carrier billing for the large prepaid, low-ARPU segments that cards don’t reach, and — increasingly — alternative app markets such as Korea’s ONE Store as it expands into the wider region. Then you sequence those channels per country, because Indonesia, Vietnam, the Philippines, Thailand and Malaysia are five different markets with five different payment habits and, in Vietnam’s case, a licensing regime that can add months to your go-to-market.

Southeast Asia is the market publishers most often treat as one line item and most often get wrong. It is big, it is mobile-first to the point of being mobile-only in places, and it is nobody’s monolith. This is the third geographic leg of our distribution series — after Latin America and MENA carrier-billing reach — and it is the one where the gap between “we launched on Play in the region” and “we actually reached the audience” is widest.

How big is the Southeast Asia mobile opportunity beyond Google Play?

Big enough that the exact number is contested, which tells you something in itself. Published forecasts for the region’s games market disagree by close to a factor of two, and the ones quoting a 2035 total to two decimal places are selling a report rather than reporting a measurement. We won’t pick one, and you shouldn’t budget against one. The estimates disagree; the shape does not. Mobile dominates, and Indonesia anchors the region.

The behavioural data is more useful than the market-sizing, and here the numbers are hard. According to Sensor Tower, Southeast Asia generated 1.93 billion new mobile-game installs in Q1 2025 — the second-largest download market on earth — against US$625 million of in-app-purchase revenue in the same quarter. Do the division and you get about $0.32 of IAP per install per quarter. That single ratio is the whole strategic problem in one figure: enormous install volume, thin per-user spend. This is a reach-and-conversion market, not a whale market, and the distribution stack has to be built for that.

Indonesia leads on volume too: 870 million of those Q1 installs were Indonesian, with the Philippines second at 366 million and Vietnam third at 329 million (Sensor Tower). On revenue, Thailand punches above its download weight — US$162 million of IAP in the quarter, the regional leader. Five markets, five profiles: Indonesia is scale, Thailand is spend, the Philippines and Vietnam are volume with conversion friction.

If you are weighing whether to build this stack in-house or run it through a partner who already has the OEM and telco relationships wired in, that is exactly the kind of decision our distribution practice exists to de-risk — the channel economics below are the same ones we model with studios.

Why does carrier billing still matter in Southeast Asia?

Because a large share of the players are prepaid and unbanked, and $0.32-per-install economics only work if the paying friction is near zero. Direct carrier billing (DCB) charges the purchase to the player’s phone balance — no card, no bank account, one tap. In the low-ARPU segments that make up the bulk of Southeast Asian installs, it is frequently the difference between a payer and a non-payer, not a nice-to-have.

We wrote the full mechanics up in our guide to why carrier billing converts where cards don’t, and mapped the emerging-market reach in the 2026 carrier-billing reach map — where mature Southeast Asia is the benchmark every other region is measured against. The short version for this playbook: Indonesia’s DCB habit (topping up game balances from Telkomsel or XL Axiata prepaid credit) is entrenched enough that operators now bill full Western subscriptions through it. The Philippines, Thailand and Vietnam all normalised paying for digital goods through the operator years ahead of India or Africa. If your title monetises through sub-dollar impulse purchases, DCB is not a secondary rail in these markets — for a big slice of the audience it is the rail.

The OEM layer: why Xiaomi is the channel you’re underusing

Hardware is where Southeast Asian distribution quietly diverges from the Western duopoly. Omdia reported that Xiaomi reclaimed the number-one smartphone spot across Southeast Asia in Q2 2025 — its first regional lead since 2021 — shipping 4.7 million units for a 19% share. In Vietnam, Xiaomi returned to top-two with roughly 19% in Q1 2025; in the Philippines, Canalys had Xiaomi second at 16% and the only major brand still growing in a slumping Q1 2025.

Why does the OEM matter to a distribution decision? Because on those devices the manufacturer’s own store (Xiaomi GetApps, and the preload slots the manufacturer controls) ships with the phone, and it usually bundles carrier billing as the default payment rail — solving reach and conversion in the same integration. A preload or a featured placement on a device brand that is number one or two in your target country is discovery you don’t pay a CPI for. We compare the mechanics in the OEM app stores comparison, and the deal-side of it in how to land an OEM preload deal. For Southeast Asia specifically, “which OEM is winning this country this quarter” should be a line in your launch plan, not an afterthought.

On the alternative-store side, the other 2025 development worth tracking is Korea’s ONE Store going regional: it launched an alternative app market in Taiwan with local publisher HAPPYTUK under a hyperlocalisation model, partnering with the market’s largest game publisher rather than going in cold. It is not pan-SEA yet, but it is the clearest signal that the alt-store playbook — local partner, local payments, games-first catalogue — is expanding across the region.

Why is Vietnam the hardest Southeast Asian market to enter?

Regulation. Vietnam is the market where distribution and legal are the same conversation, and it is the reason a regional launch shouldn’t treat all five countries as one sprint. Foreign publishers effectively need a licensed local entity or partner, and multiplayer titles fall under the strictest “G1” licence class, which requires a formal decision-to-publish from the Ministry of Information and Communications.

That regime tightened hard in 2024. In April, Vietnam’s MIC suspended the G1 licences of 49 enterprises in a single order (Decision 543/QĐ-BTTTT) for failing licence conditions and reporting duties — a three-month suspension that converts to revocation if the violations aren’t cured. Then Decree 147/2024, issued in November and effective 25 December 2024, overhauled the whole framework: it obliges foreign app-store providers to pull non-compliant titles on request, bans casino- and card-style mechanics, and prohibits trading in-game items for real-world value. Between the suspensions and the new decree, the pool of valid G1 licences shrank materially over the year.

The operational takeaway: budget for a licensed local partner and a go-to-market measured in quarters, not weeks, if your Vietnam title is multiplayer. It is a genuinely large market — 329 million Q1 2025 installs — but it is the one where “just publish it” is the fastest way to get pulled.

The entry playbook: localization and payments, market by market

A practical sequencing model for a publisher switching on the region, tuned to where volume, spend and friction actually sit:

Market	Distribution priority	Payment must-haves	Localisation
Indonesia	Play + Xiaomi/OEM preloads; DCB baked in	DCB (Telkomsel, XL Axiata) is primary, not optional	Bahasa Indonesia; mobile-only UX
Philippines	Play + Xiaomi placement; alt-store optional	DCB for prepaid; e-wallets (GCash)	English works, but Filipino localisation lifts casual reach
Vietnam	Local licensed partner first; then Play + OEM	DCB via Viettel/Vinaphone/Mobifone	Vietnamese required; plan for G1 licensing lead time
Thailand	Play + OEM; highest spend, prioritise monetisation	Cards convert better here; DCB + TrueMoney	Thai localisation; skew toward mid-core spend
Malaysia	Play + OEM; smaller but higher-ARPU	Cards + DCB; higher banked share	Malay + English

Three rules cut across the table. First, localise the store listing and the payment sheet before the UI — a Bahasa Indonesia listing with Telkomsel billing beats a fully localised game with card-only checkout. Second, treat Indonesia as the volume anchor and Thailand as the revenue anchor, and don’t expect the same title to over-index on both. Third, stagger Vietnam — its licensing timeline means it should almost never be in your day-one cohort unless your local partner is already in place.

For studios thinking about how this regional stack fits a global channel plan rather than a one-off SEA push, it slots directly into the sequencing logic in our multi-channel distribution framework.

FAQ

Do I need to leave Google Play to distribute in Southeast Asia?

No — you layer on top of it. Google Play remains the base channel across the region, but relying on it alone leaves reach and conversion on the table. The additive channels are OEM preloads and stores (Xiaomi especially), direct carrier billing for prepaid and unbanked players, and alternative app markets. The goal is a stack, not a store switch.

Which Southeast Asian market should a publisher launch first?

Indonesia for scale — it drove 870 million of the region’s 1.93 billion Q1 2025 installs (Sensor Tower) and anchors regional spend. Thailand is the revenue-first alternative, leading the region on in-app-purchase revenue in the same quarter. Vietnam, despite huge install volume, is usually last because of its G1 licensing timeline.

Why is carrier billing so important in Southeast Asia?

Because a large share of players are prepaid and unbanked, and regional per-install spend is thin — roughly $0.32 of IAP per install in Q1 2025 (Sensor Tower). Direct carrier billing charges purchases to the phone balance with no card or bank account, which is often the difference between a payer and a non-payer in the low-ARPU segments that make up most of the audience.

What makes Vietnam harder than the rest of the region?

Licensing. Multiplayer titles need a G1 licence and, in practice, a licensed local partner. In 2024 Vietnam’s MIC suspended 49 companies’ G1 licences in one order, and Decree 147/2024 (effective December 2024) tightened content rules and app-store obligations further. Expect a go-to-market measured in quarters, not weeks.

Is Xiaomi really a distribution channel and not just a phone brand?

Yes. Xiaomi was the number-one smartphone brand across Southeast Asia in Q2 2025 (Omdia) and top-two in both Vietnam and the Philippines. On those devices its store and preload slots are a discovery channel that usually bundles carrier billing as the default payment — reach and conversion in one integration, without a CPI attached.
