The Concept
The simplest possible input. The most useful possible output.
Most tracking solutions require hardware installed on the vehicle, an app running on the driver's phone, or a complex device management system. Dotmove's SIM number tracker reduces the entire problem to its essential elements — a phone number goes in, a map coordinate comes out.

Integration Flow
From mobile number to map pin in 4 API calls
01
Authenticate
Generate a Bearer token using your API credentials. Valid for 24 hours. Pass as Authorization header on all subsequent calls.
POST /auth/token
02
Import the number
Pass the MSISDN to the Import API. Dotmove registers it in your account and queues the consent workflow.
POST /import
03
Collect consent
Dotmove sends SMS or IVR consent to the subscriber automatically. Your system receives a consent token on confirmation.
POST /consent
04
Get location
Pass the MSISDN and consent token. Get back latitude, longitude, accuracy radius, operator, and timestamp in under 1 second.
GET /location
Code Sample
Integration designed to be live in days, not weeks
REST architecture, JSON responses, Bearer token authentication. If your team can call a REST API — and they can — they can integrate Dotmove's SIM number tracker. A complete Postman collection with sample requests and responses is available on request.
API Response
Explanation : Every field in the location response
lat LONG
Latitude coordinate of the tracked MSISDN's current location. Combine with lng to get a precise geographic point.
operator STRING
The telecom operator that resolved the location — Airtel, Jio, or Vi. Resolved automatically. Your code never needs operator-specific logic
lng FLOAT
Longitude coordinate. Pass lat and lng directly to any mapping library — Google Maps, Mapbox, Leaflet — to render a pin.
timestamp ISO 8601
UTC timestamp of when the location was resolved. Use to calculate location freshness and determine whether to query again.
accuracy_m INTEGER
Accuracy radius in metres. Draw a circle of this radius around the lat/lng point — the device is within this circle. Use to set confidence thresholds in your logic.
status STRING
Query status — success, pending_consent, consent_expired, or out_of_coverage. Build your error handling logic around these four states.
Rendering On Your Dashboard
Lat/Long to MAP Pin : Works with every major mapping library
The coordinates Dotmove returns are standard WGS84 latitude/longitude — the same format used by Google Maps, GPS devices, and every major mapping platform. No coordinate conversion, no projection handling, no proprietary format. Drop the lat/lng into your mapping library and the pin renders immediately.
Compatible with all major mapping libraries
Pass lat and lng from the API response directly to any of these libraries. Use accuracy_m to draw a confidence circle around the pin.

Bulk SIM Number Tracking
One API call : Track hundreds of numbers simultaneously
Bulk Location API
For fleet and workforce deployments tracking hundreds or thousands of numbers, making individual API calls per number is inefficient. Dotmove's Bulk Location API accepts up to 500 MSISDNs in a single call and returns coordinates for all numbers in one response — dramatically reducing API call volume, latency, and cost for large-scale deployments.
500
MSISDNs per bulk call — all operators, single response
Free Utility Dashboard
Once your SIM number tracker is live, Dotmove's free utility dashboard gives your operations team real-time visibility without writing code. Monitor every tracked number, check consent status, reinitiate failed consents, and inspect API responses — directly from a web interface.

Accuracy
The accuracy_m field in the API response tells you the radius of confidence around the returned coordinates. Here is what to expect at each signal source — and what operational decisions are reliable at each level.
Signal Source | accuracy_m range | Reliable for |
|---|---|---|
AGPS / Active smartphone | 5–20m | Delivery confirmation, geofence entry/exit, proof of visit |
Cell tower triangulation — urban | 50–150m | Route adherence, zone monitoring, dispatch decisions |
Cell tower — rural / highway | 200m–2 km | General location awareness, ETA calculation, deviation alerts |
HLR fallback — 2G / feature phone | Network-level | Last-known location, connectivity status — not real-time |
