Siamproxy Alternative: Coronium 4G/5G Mobile Proxies
Bangkok-only 3-MNO Thai operator vs 20+ country managed operator with v3 REST API.
Siamproxy (siamproxy.com) is a Thailand-only dedicated 4G LTE mobile proxy operator with infrastructure in Bangkok sourcing from AIS, DTAC, and TrueMove H — Thailand's three major MNOs — at $5/24-hour, $20/week, $50/month per port with UDP via OpenVPN, crypto-only payment, and Telegram support (@siamproxy). Coronium operates dedicated 4G/5G modems in 20+ countries with v3 REST API and four-tier reseller wholesale program — but does not currently include Thailand.
TL;DR — Quick Verdict
Siamproxy wins on Thailand exclusivity — Coronium does not list Thailand directly. They also publish 24-hour day-passes ($5), three-MNO carrier transparency (AIS + DTAC + TrueMove H), UDP via OpenVPN, and crypto-only payment. Coronium wins on country breadth (20+ vs 1), reseller depth, and v3 REST API — for any workload outside Thailand. Hybrid use is rational: Siamproxy for Thai-targeted workloads, Coronium for everything else.

Methodology
Compared on six public, verifiable axes: country coverage, Thai carrier-mix, pricing tier structure, protocol depth, payment rails, default rotation. Siamproxy figures sourced from siamproxy.com (verified 2026-04-30). Coronium catalog publicly listed. Independent authorship; no paid placement with Siamproxy.
Verified 2026-04-30. Coronium does not list Thailand directly — the comparison frames Siamproxy as the Thailand-specialist option and Coronium as the multi-country alternative for everything-but-Thailand.
1. What Siamproxy does well
- Thailand exclusivity. Coronium does not list Thailand directly. For Thai-MNO IP authenticity, Siamproxy is the cleaner option in this matchup.
- Three-MNO Thai carrier mix. AIS + DTAC + TrueMove H — all three Thailand mobile network operators published explicitly. For workloads where carrier ASN diversity is a fingerprint signal at Thai-targeted platforms (TikTok TH, Lazada, Shopee TH), this matters.
- $5 / 24-hour day-pass. Lowest documented day-pass for any Thailand 4G operator. Useful for spike testing, single-day campaigns, or short-burst workloads where monthly tariffs are wasteful.
- UDP via OpenVPN config. Uncommon protocol depth for a single-country operator — supports WebRTC, gaming telemetry, modern HTTPS/3 stacks at the Thailand hop.
- 24-hour refund guarantee. Customer-friendly evaluation policy — try the service, refund if it doesn't fit.
- Crypto-only payment privacy. No card payment trail — relevant for buyers operating in jurisdictions where card-payment KYC creates friction.
2. Thai carrier-mix context
Thailand's mobile market is dominated by three MNOs with deep market shares. Carrier ASN diversity matters at fingerprint-sensitive Thai-targeted platforms.
| Thai MNO | Subscriber base (approx.) | Position |
|---|---|---|
| AIS (Advanced Info Service) | ~46M subscribers | Largest Thai MNO; broadest 5G + 4G coverage |
| TrueMove H | ~33M subscribers | Strong 4G + aggressive 5G rollout; metro focus |
| DTAC (Total Access Communication) | ~21M subscribers | Budget-tier carrier; merged with True Move under True Corporation 2023 |
Note: True and DTAC merged under True Corporation in 2023 — the legacy DTAC IP space is still operational and maintained alongside TrueMove H. For workloads bound to a specific Thai MNO, Siamproxy's explicit publishing is operationally useful.

4. Decision matrix
Pick Siamproxy if
- •Workload is Thailand-bound — Coronium does not list Thailand directly.
- •You need short-burst Thai testing — $5/24h day-pass enables single-day campaigns.
- •Specific Thai MNO (AIS, DTAC, TrueMove H) carrier choice matters.
- •You need UDP via OpenVPN at the Thailand hop.
- •Crypto-only payment fits your accounting / privacy profile.
Pick Coronium if
- •Workload is anywhere except Thailand — Coronium covers 20+ countries Siamproxy doesn't.
- •You're reselling — REST API, white-label per-port credentials, USDC top-up, 4-tier wholesale.
- •You need Indonesia, Singapore, Vietnam, Philippines, India, Japan, China, AU/NZ — Coronium catalog covers most APAC alternatives.
- •Replacement credits, prorated cancel, atomic stock-aware buy as documented APIs reduce ops burden.
- •Hybrid use: Siamproxy for Thailand workload + Coronium for everything else.
