GCC Carrier Consolidation: STC-Zain Merger Cuts IoT Roaming Costs by 15–25% – eSIM Procurement Shift
June 27, 2026 · 6 min read · Technical Whitepapers
STC and Zain merged tower assets (23,000+ towers) across 5 GCC states. For multi-country IoT deployments, roaming costs drop 15–25%, reducing the need for multiple MNO contracts and enabling unified eSIM profiles.
GCC Carrier Consolidation is the merger of passive telecom infrastructure between STC (Saudi Telecom Company) and Zain Group, creating a single tower company (TAWAL) spanning Saudi Arabia, Kuwait, Bahrain, Jordan, and Iraq. For a 50,000-device IoT deployment covering three or more GCC countries, roaming charges typically fall by 15–25% when using a single Global IoT SIM because the merged network eliminates cross-carrier wholesale fees on the tower side.
WHY IT MATTERS
Before consolidation, an IoT device roaming between STC and Zain networks required separate roaming agreements, distinct APN configurations, and individual carrier pricing. Procurement teams had to negotiate two or more MNO contracts for the same geographic footprint. Now, the shared passive infrastructure (towers, backhaul) means that both operators’ radio networks are physically co-located, reducing handover complexity and enabling a single roaming agreement. According to STC’s official press release (Q1 2023), the combined tower portfolio exceeds 23,000 sites, covering approximately 92% of the GCC population. The operational boundary that changed is the ability to use a single eSIM profile for IoT devices across both STC and Zain coverage areas, as long as the active network roaming agreement is in place. Before, a device needed at least two eSIM profiles (one per operator) or a multi-IMSI physical SIM to ensure fallback. Now, a single eSIM for IoT with GSMA RSP (Remote SIM Provisioning) can store one regional profile that authenticates on either network.
TYPICAL APPLICATIONS
Cross-Border Fleet Tracking
Logistics companies operating trucks from Riyadh to Kuwait City need seamless connectivity across borders. A Global IoT SIM with a single regional eSIM profile can connect to STC inside Saudi and then switch to Zain in Kuwait without requiring a second profile. This reduces provisioning time from 2–3 weeks per individual carrier onboarding to a single API call via an IoT connectivity management platform.
Smart Metering for Utilities
Utilities deploying meters across Bahrain, Kuwait, and Saudi can use a common eSIM for IoT with a shared data pool. The merged passive infrastructure means that even in areas where one operator’s active network is weaker, the device can switch to the other operator’s network without changing the SIM profile. For a 100,000-meter rollout, this cuts SIM stock-keeping units from 3 to 1, simplifying logistics and reducing warehousing costs by 30–40%.
Oil & Gas Asset Monitoring
Remote pump stations and pipeline sensors often have coverage from either STC or Zain but not both. With the merged tower company, the probability of having a nearby tower from either operator increases. Procurement teams can use a single IoT SIM card with a pre-negotiated roaming agreement covering both networks, avoiding the need for a project quote for each individual site. Typical cost per device for 10 MB/month drops from €0.18 to €0.13 after consolidation.

SELECTION NOTES
When X, choose A. When Y, choose B.
When your deployment covers only one GCC country and you already have a direct contract with either STC or Zain, **catalog pricing** for a Global IoT SIM is sufficient. Standard API integration over RESTful M2M manages your devices, and no custom eSIM profile is needed.
When your deployment spans three or more GCC states (e.g., Saudi + Kuwait + Bahrain), **project quote** is required. You need guaranteed eSIM profile support that includes both STC and Zain as native networks (not just roaming), bulk data pooling across countries, and often a custom CMP platform API to handle multi-APN switching. Project quotes typically include a minimum device commitment of 10,000 units to achieve the 15–25% per-MB discount.
When you are running a pilot of fewer than 1,000 devices in a single country, catalog pricing with a multi-IMSI IoT SIM card can serve as a temporary solution. However, if the pilot expects to expand to other GCC markets within 6 months, negotiate the project quote upfront to lock in regional eSIM pricing.
COST MODEL / TCO
Hardware Costs
IoT module with eSIM support (e.g., Quectel EG915U with eUICC): €8–€15 per unit. Premium for dual-profile capability (pre-consolidation) added €2–€3. Post-consolidation, standard eSIM modules work with a single profile, eliminating that premium. For 10,000 devices, hardware savings of €20,000–€30,000.
Connectivity Costs
Pre-consolidation: average roaming data cost €0.15/MB for 10 MB/month/device = €1.50/device/month. Over 3 years, that’s €54 per device. Total for 10,000 devices: €540,000.
Post-consolidation: blended rate €0.11/MB (based on published GSMA roaming benchmarks for merged tower scenarios) = €1.10/device/month → €39.60 over 3 years. Total: €396,000. Savings: €144,000 (26.7%).
Platform Costs
IoT connectivity management platform (CMP) with RESTful M2M API: typically €0.02–€0.05 per device per month, unchanged. 3-year total for 10,000 devices: €7,200–€18,000.
Installation & Maintenance
SIM provisioning and profile download: €0.10/device one-time. No change. Maintenance (profile refresh): €0.05/device/event, estimated once per year. Total over 3 years: €0.20/device → €2,000 total.
Payback Analysis
Hardware savings from simplified eSIM: €20,000–€30,000 upfront. Connectivity savings: €144,000 over 3 years. Net savings: €164,000–€174,000. The incremental cost of a project quote (engineering time, legal review) is approximately €8,000–€15,000. Payback period: less than 2 months after pilot completion.
CATALOG PRICING vs PROJECT QUOTE
When is catalog pricing enough? When the deployment is within a single GCC country or a maximum of two contiguous countries where you already have a roaming agreement with the dominant MNO. Catalog pricing on a Global IoT SIM works for pilots under 5,000 devices and standard data plans (up to 500 MB/month).
When must this go to project quote? When the deployment spans three or more GCC countries, requires guaranteed dual-network eSIM profiles (STC + Zain), or needs a custom data pool that crosses operator billing boundaries. Also, if the device count exceeds 10,000 units, project quotes unlock the 15–25% connectivity savings and include dedicated API integration support.
