Southeast Asian Carrier Mergers Cut IoT Roaming Costs Up to 40% – What Procurement Needs to Know
· 5 min read · Technical Whitepapers
Mergers in Thailand, Malaysia, and Indonesia reduce inter-carrier charges by 30-40%. For a 10,000-device fleet telematics deployment, multi-carrier eSIM profiles are now 25% cheaper than roaming.
Southeast Asian carrier mergers are the consolidation of mobile network operators in Thailand (TrueMove+DTAC), Malaysia (Celcom+Digi), and Indonesia (Indosat+3) into single entities. For a 10,000-device fleet telematics deployment, data roaming costs drop 35% when switching from individual carrier roaming agreements to post-merger integrated eSIM profiles.
WHY IT MATTERS
Before mergers, IoT roaming in Southeast Asia required separate bilateral agreements with 2-3 carriers per country, each with different rates averaging €0.50/MB. Post-merger, the combined entity offers a single SIM profile with home-network pricing – typically €0.08/MB for bulk data. GSMA roaming statistics show inter-operator wholesale rates fell 30-40% after consolidation in Thailand (2023) and Malaysia (2022). This changes procurement: you no longer need multi-IMSI physical SIMs; single eUICC eSIM with multi-carrier profiles suffices. The operational boundary shifts from managing multiple carrier contracts to one master agreement with integrated API access to a CMP platform.
TYPICAL APPLICATIONS
Fleet Telematics across Thailand, Malaysia, Indonesia
Fleet operators managing cross-border logistics need continuous connectivity. Pre-merger, a fleet of 5,000 trucks crossed an average of 2 borders per trip, incurring roaming costs of €0.12 per MB. Post-merger, a Global IoT SIM with eSIM profile from the merged carrier achieves €0.04 per MB using local breakout. Deployment uses eSIM remote provisioning (GSMA SGP.32) and a CMP platform for profile switching. Catalog pricing is available for fleets under 2,000 devices; above that, a project quote secures volume discounts.
Smart Metering in Rural Malaysia
Smart meters require NB-IoT or LTE-M. The CelcomDigi merger unified network coverage, reducing the need for dual-carrier SIMs. A project quote for 50,000 meters now uses a single eSIM profile with fallback to the partner network, saving 20% on hardware (single SIM slot) and 15% on connectivity. Catalog pricing applies for deployments under 1,000 units.
Connected POS Terminals in Urban Indonesia
Indosat+3 merger consolidated 4G coverage in Java. POS terminals using eSIM from the merged carrier benefit from no roaming surcharge for inter-island traffic. Procurement now chooses catalog pricing for <500 units, project quote for >2,000 units to negotiate volume discounts down to €0.06/MB.
TECHNICAL SPECIFICATION / COMPARISON TABLE
| Dimension | Pre-Merger (Individual Carriers) | Post-Merger (Consolidated) | Procurement Impact |
|---|---|---|---|
| Roaming Data Cost (€/MB) | €0.50 avg | €0.08 avg | Reduces connectivity TCO by 84% |
| Inter-carrier Handoff Latency | 500 ms | 150 ms | Enables real-time asset tracking |
| SIM Profile Count Required | 3 (multi-IMSI physical) | 1 (eUICC eSIM) | Lowers eSIM hardware cost by €2/unit |
| Contract Complexity | 3 separate agreements | 1 master agreement | Reduces legal review cost by 60% |
| Data volume threshold for negotiation | 10 GB/month | 50 GB/month | Catalog pricing sufficient for <50 GB |
SELECTION NOTES
When total monthly data per device is under 50 MB (e.g., sensor reporting), catalog pricing from an IoT connectivity provider with Global IoT SIM is sufficient – typical €0.05/MB for merged SEA coverage. When deployment exceeds 10,000 devices or requires custom traffic steering (e.g., least-cost routing via CMP API), a project quote is required; expect 30-40% discount vs catalog for 50,000+ device commitment. When using eSIM with multi-carrier profiles, always choose a vendor that supports GSMA SGP.32 for remote profile management. Physical SIMs are still viable for deployments under 5,000 devices but lose the cost advantage of post-merger integrated pricing.
COST MODEL / TCO
Hardware Costs
eSIM module + PCB redesign (if switching from physical SIM): €2 per unit vs €1.5 for physical SIM. Net increase €0.5/unit = €5,000 for 10,000 devices.
Connectivity Costs
Pre-merger roaming €0.50/MB × 10 MB/month = €60/device/year = €1.8M over 3 years. Post-merger €0.08/MB = €0.96M. Savings €0.84M.
Platform Costs
CMP platform at €0.10/device/month = €12,000/year = €36,000. API integration €5,000 one-time.
Installation
eSIM provisioning via remote profile download – no SIM insertion cost. Physical SIM installation cost €0.20/unit saved.
Maintenance
Profile management API reduces manual SIM swaps by 90%, saving €0.05/device/month = €6,000/year.
Payback
Hardware cost increase recouped in first month of connectivity savings. Total TCO reduced by 45% (from €2.0M to €1.1M over 3 years).
When is catalog pricing enough? For standard regional eSIM profiles with fixed data allowances (e.g., 100 MB/month) for fleets under 5,000 devices. When must this go to project quote? For custom data tiers, multi-operator fallback, or deployments exceeding 10,000 devices where volume discounts apply.

Frequently Asked Questions
How much can carrier mergers reduce IoT roaming costs in Southeast Asia?
Data roaming costs drop 30-40% based on post-merger integration. For example, TrueMove+DTAC merger in Thailand reduced average per-MB cost from €0.50 to €0.08 for bulk IoT data.
Should I switch from physical SIMs to eSIM for deployments in merged SEA markets?
Yes, if your deployment exceeds 5,000 devices. eSIM with multi-carrier profiles under SGP.32 reduces hardware cost by €2/unit and enables dynamic profile switching without manual SIM swaps. For smaller deployments, physical SIMs remain cost-effective.
What procurement contract type is best for cross-border IoT in Thailand and Malaysia?
For fleets over 10,000 devices, a project quote with vendor that offers CMP API and volume discounts (30-40% off catalog) is optimal. Below 5,000 devices, catalog pricing from a Global IoT SIM provider is sufficient.
How does the CelcomDigi merger affect smart meter connectivity pricing?
The merger unified NB-IoT and LTE-M coverage, allowing single-profile eSIMs. Connectivity costs dropped from €0.12/MB to €0.05/MB for 50,000+ meter deployments, with catalog pricing available for under 1,000 units.
