Siamproxy Alternative: Coronium 4G/5G Mobile Proxies
Bangkok-only 3-MNO Thai operator vs multi-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 multiple countries with v3 REST API and reseller program with volume discount codes - and lists Thailand (TRUE-H), with no lines in stock today.
TL;DR - Quick Verdict
Siamproxy wins on Thailand depth - Coronium lists Thailand (TRUE-H) but has no lines in stock today. 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 (multi-country 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 lists Thailand (TRUE-H) but has no lines in stock today - the comparison frames Siamproxy as the Thailand-specialist option and Coronium as the multi-country alternative.
1. What Siamproxy does well
- Thailand exclusivity. Coronium lists Thailand (TRUE-H) but has no lines in stock today. 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
- โขWorkload is Thailand-bound - Coronium lists Thailand (TRUE-H) but has no lines in stock today.
- โขYou need short-burst Thai testing - $5/24h day-pass enables single-day campaigns.
- โขSpecific Thai MNO (AIS, DTAC, TrueMove H) carrier choice matters.
- โขYou need UDP via OpenVPN at the Thailand hop.
- โขCrypto-only payment fits your accounting / privacy profile.
Pick Coronium if
- โขWorkload is anywhere except Thailand - Coronium lists more countries Siamproxy doesn't.
- โขYou're reselling - REST API, white-label per-port credentials, crypto top-up, volume discount codes.
- โขYou also need Singapore, Indonesia, Australia or New Zealand lines - check which of these Coronium currently lists.
- โขReplacements, API cancel, atomic stock-aware buy as documented APIs reduce ops burden.
- โขHybrid use: Siamproxy for Thailand workload + Coronium for everything else.
