Quick answer
Global asset tracking does not fail because of lack of coverage. It fails because of lack of reliability within that coverage. Single-IMSI SIMs depend on roaming and degrade across regions. At scale, you need multi-network access, multi-IMSI switching, and CMP control to maintain consistent tracking performance.
Why global asset tracking fails at scale
Most deployments start with:
- a global SIM
- a single connectivity provider
- a simple tracking platform
It works in early stages.
It fails when assets move across:
- countries
- networks
- environments
What actually happens in motion
When an asset moves, connectivity is not stable.
It is constantly changing.
Example: container in transit
- Leaves warehouse → strong urban network
- Moves to port → congested network environment
- Loaded onto ship → intermittent or no signal
- Arrives in new country → roaming profile activated
- Moves inland → different network conditions
At each step:
- signal strength changes
- network availability changes
- roaming rules apply
Where tracking breaks
1. Network handovers
- device stays connected to previous network
- does not switch to stronger one
2. Roaming transitions
- SIM connects as roaming user
- lower priority on network
3. Signal loss environments
- containers
- underground locations
- rural areas
4. No fallback logic
- device cannot switch networks dynamically
Result
You don’t lose coverage.
You lose continuous visibility.
Coverage vs reliability: the real distinction
Coverage (what providers sell)
- number of countries
- number of partner networks
- roaming footprint
Problem:
Coverage is theoretical availability.
Reliability (what operations need)
Reliability is the ability to maintain:
- consistent connection
- stable data transmission
- predictable performance
What defines reliability (technical view)
- network availability per location
- latency consistency
- packet delivery success rate
- connection persistence
- automatic fallback behaviour
Without these, tracking data becomes unreliable.

How global asset tracking connectivity works
Typical data flow
- Device captures GPS location
- Connects to mobile network
- Sends data packet to backend
- Backend processes and visualises
What happens under the hood
- device attaches to available cell tower
- network determines routing path
- data transmitted via operator core network
Where failures occur
1. Device layer
- weak signal
- battery constraints
2. Network layer
- poor network selection
- roaming prioritisation
3. Routing layer
- inefficient paths
- latency spikes
4. Platform layer
- no retry logic
- no visibility
Single-IMSI vs multi-IMSI: what actually changes
Single-IMSI model
- one operator identity
- limited network access
- dependent on roaming
In practice:
- device connects to suboptimal network
- no fallback available
- retries increase battery drain
Multi-IMSI model
- multiple operator identities
- dynamic selection of best network
How switching works
- device evaluates available networks
- selects based on signal and performance
- switches when conditions degrade
Real impact
- fewer dropped connections
- more consistent data
- lower retry overhead
- improved battery life
What breaks in real logistics deployments
Scenario 1: Cross-border transport
- asset moves between countries
- roaming profile activated
Failure:
Impact:
- delayed updates
- missing data points
Scenario 2: Maritime transport
- long periods of no signal
- intermittent connectivity
Failure:
- no buffering or retry logic
Impact:
Scenario 3: Urban congestion
- multiple networks available
Failure:
- device stuck on poor network
Impact:
Scenario 4: High-value asset tracking
- need continuous monitoring
Failure:
Impact:
- loss of asset visibility
- increased theft risk
Data pooling: cost and efficiency at scale
Traditional SIM model
- fixed data per device
- unused data wasted
At scale
Fleet example:
- 10,000 trackers
- usage varies widely
Without pooling:
- overpay for unused data
- inefficient allocation
Data pooling model
- shared data across all devices
What changes
- heavy users draw from pool
- low users do not waste allocation
Impact
- predictable cost
- improved utilisation
- easier forecasting
How to design a reliable global tracking network
1. Multi-network access
- more than one network per country
- avoid single operator dependency
2. Multi-IMSI SIM architecture
- dynamic switching
- fallback capability
3. CMP (control and visibility)
This is the operational core.
You need:
- real-time device status
- connectivity diagnostics
- alerting on failures
- usage insights
- automation rules
4. Retry and buffering logic
- store-and-forward when offline
- retry when connection restored
5. Private routing (for sensitive assets)
- controlled data paths
- reduced exposure
Why coverage alone is not enough
You can have:
- 190+ countries
- global SIM
- strong provider
And still experience:
- tracking gaps
- unreliable data
- operational blind spots
Because:
- coverage ≠ performance
- roaming ≠ reliability
- connectivity ≠ control
Why enterprises choose IXT for global asset tracking

FAQs
What is global asset tracking?
Global asset tracking uses connected devices to monitor location and status of assets across multiple regions, networks, and transport conditions.
Why do tracking devices fail in transit?
Failures occur due to roaming limitations, poor network selection, signal variability, and lack of fallback connectivity. Devices often remain connected to weak networks without switching.
What is the difference between coverage and reliability?
Coverage refers to where a device can connect. Reliability refers to how consistently it maintains performance, data transmission, and connection quality across regions.
What is multi-IMSI in asset tracking?
Multi-IMSI allows a device to switch between multiple operator identities, enabling better network access and improving reliability during movement.
How do you improve tracking reliability?
Use multi-network connectivity, automatic switching, real-time monitoring, and proper retry logic to maintain consistent data flow.
Why is roaming unreliable for tracking?
Roaming users often receive lower network priority, leading to reduced performance, higher latency, and connection instability.
What affects battery life in tracking devices?
Frequent retries, poor signal conditions, and inefficient network selection increase power consumption and reduce battery life.
What is data pooling in IoT?
Data pooling allows multiple devices to share a common data allowance, improving utilisation and reducing cost inefficiencies.
How do you manage tracking devices at scale?
Using a CMP that provides visibility, diagnostics, alerting, and control across all devices.
What is the best connectivity model for logistics?
A model combining multi-network access, multi-IMSI switching, CMP control, and cost optimisation provides the most reliable tracking.
Can asset tracking data be secured?
Yes. Using private routing and controlled network paths reduces exposure and improves data security.
