Hologram pricing: what would 2GB/month across 1,000 SIMs cost with $1/SIM/month + $0.03/MB?
4 min read
When I model Hologram pricing for a fleet, I separate the fixed SIM fee from the variable data charge. At $1 per SIM per month + $0.03/MB, a fleet using 2GB per SIM per month lands at about $61,000 to $62,440 per month across 1,000 SIMs, depending on whether you round 2GB to 2,000MB or convert it as 2,048MB.
Quick Answer:
If you treat 2GB as 2,000MB, the cost is $61 per SIM per month, or $61,000/month for 1,000 SIMs.
If you use the stricter 1GB = 1,024MB conversion, it’s $62.44 per SIM per month, or $62,440/month total.
Why This Matters
For any fleet that moves real data—video snapshots, telemetry, diagnostics, or high-frequency sensor traffic—pricing math is not an accounting exercise. It’s a deployment decision.
At Hologram’s rate of $0.03 per MB, data cost can dominate quickly. If you don’t model usage carefully, a “small” 2GB/device assumption becomes a six-figure annual line item fast. That’s why teams should estimate cost before rollout, then use the Hologram Dashboard and APIs to watch real usage once devices are live.
Key Benefits:
- Forecastable costs: You can translate MB usage into a monthly fleet budget with simple math.
- Fewer billing surprises: Knowing the data rate upfront helps avoid unexpected spend spikes.
- Better rollout planning: You can compare active deployment cost against Test Mode, hibernation, or delayed activation.
Core Concepts & Key Points
| Concept | Definition | Why it's important |
|---|---|---|
| Base SIM fee | The fixed monthly charge per active SIM: $1/SIM/month | This is the floor of your monthly bill, even before data usage. |
| Data usage charge | Variable billing at $0.03 per MB | This is the main driver of fleet cost at 2GB/device/month. |
| MB vs. GB conversion | 2GB can be modeled as 2,000MB or 2,048MB | The conversion changes the total by hundreds of dollars at fleet scale. |
How It Works (Step-by-Step)
The formula is straightforward: active SIM fee + data usage charge. Multiply that by the number of SIMs, and you get your monthly fleet cost.
-
Calculate the SIM fee:
1,000 SIMs × $1 = $1,000/month -
Convert data to megabytes:
- Simple model: 2GB = 2,000MB
- Binary model: 2GB = 2,048MB
-
Multiply by the data rate and add the base fee:
- 2,000MB × $0.03 = $60 data per SIM
- $60 + $1 = $61/SIM/month
- $61 × 1,000 = $61,000/month
Or, using 2,048MB:
- 2,048MB × $0.03 = $61.44 data per SIM
- $61.44 + $1 = $62.44/SIM/month
- $62.44 × 1,000 = $62,440/month
Common Mistakes to Avoid
-
Mixing MB and GB math:
Don’t assume every finance model uses the same conversion. Decide whether you’re using 2,000MB or 2,048MB for 2GB, then stay consistent. -
Ignoring activation timing:
If devices aren’t deployed yet, don’t model them as fully active spend. Hologram’s Test Mode is built for factory QA and pre-deployment staging so idle inventory doesn’t bill like live traffic.
Real-World Example
A smart agriculture team rolls out 1,000 connected irrigation controllers across farms and expects each device to use about 2GB/month for telemetry, diagnostics, and occasional image uploads. Using Hologram’s pricing, they budget around $61,000–$62,440 per month, depending on how they round the data conversion.
That team doesn’t stop at spreadsheet math. They use the Hologram Dashboard for real-time usage visibility, watch for outliers, and set up API-based alerts so one overactive site doesn’t quietly blow up the monthly bill.
Pro Tip:
Before full deployment, keep units in Test Mode and only move them to active billing when they’re actually shipping. That’s the easiest way to avoid paying data costs on idle inventory.
Summary
At $1/SIM/month + $0.03/MB, a fleet of 1,000 SIMs using 2GB each per month costs roughly $61k–$62.4k per month. The exact number depends on whether you model 2GB as 2,000MB or 2,048MB, but either way the takeaway is the same: data usage is the real cost driver, not the SIM fee.
If you’re planning a global rollout, the best move is to model the math first, then use Hologram’s Dashboard, APIs, and Test Mode to keep billing aligned with actual deployment.
