4G AIS-140 device — compliance that outlives 2G.
Thousands of older AIS-140 fitments run on 2G modems that are going dark as networks sunset. The GPSBULL AIS-140-4G is a true 4G LTE AIS-140 tracker with dual-network embedded SIM — certified today, connected for the next decade.
Why "4G" matters in an AIS-140 device
An AIS-140 device is a long-life fitment: it is wired into the vehicle, registered against the registration number on Vahan, and expected to report for years. A 2G-only device fails that expectation — as Indian operators re-farm 2G/3G spectrum for 4G and 5G, older VLTDs silently stop reporting, breaking compliance and leaving panic buttons dead.
The GPSBULL AIS-140-4G connects on 4G LTE with a dual-network embedded SIM (eSIM): if one network weakens, the device switches — no SIM swaps, no downtime, no re-fitment visits.
2G VLTD vs 4G AIS-140 device
| Old 2G VLTD | GPSBULL AIS-140-4G | |
|---|---|---|
| Network life | Ends with 2G sunset | 4G LTE — supported for years ahead |
| SIM | Physical, single network | Dual-network embedded eSIM |
| Positioning | Often GPS only | GPS + GLONASS + IRNSS (NavIC) |
| Interfaces | Basic I/O | Bluetooth · RS-232 · RFID · CAN support |
| Updates | Bench reflash | Remote, over the air |
Model: GPSBULL-4G · TRP-4G · Part TRP-024 — AIS-140 certified with ARAI type approval TAC AS9026, IP68 housing, 12/24 V supply, panic-button and tamper-alert support.
Upgrading a fleet from 2G AIS-140 devices
If your buses or taxis were fitted years ago, an upgrade is straightforward: the 4G device replaces the old unit in the same fitment, the new IMEI is re-linked on the Vahan portal, and backend reporting continues to your state's transport server. GPSBULL supports operators and fitment centres through the whole swap — device, documentation guidance and activation — with 24/7 support after.

Frequently asked questions
What is a 4G AIS-140 device?
An AIS-140 certified vehicle location tracking device whose modem connects on 4G LTE networks instead of 2G — like the GPSBULL AIS-140-4G (TRP-4G) with dual-network embedded SIM and ARAI type approval TAC AS9026.
My current VLTD is 2G — do I have to replace it?
When the 2G network it uses is switched off in your circle, the device stops reporting and compliance breaks. Upgrading to a 4G AIS-140 device ahead of the sunset avoids permit and fitness-certificate problems.
Does the 4G device work where 4G coverage is weak?
The dual-network embedded SIM lets the device use whichever supported network serves the location best, keeping vehicles reporting across routes.
Is the 4G AIS-140 tracker more expensive than 2G?
Factory-direct 4G pricing is closer to old 2G pricing than most operators expect — and a 2G device fitted today has a short useful life. Call 1800 123 8677 for a quote for your state and quantity.
Will the panic buttons work with the upgraded device?
Yes — existing AIS-140 panic buttons wire into the GPSBULL 4G device, and alerts route to the state backend as per the standard after re-activation.
