Cradlepoint 170875-000 T-Mobile SIM for ACS
Overview
The Cradlepoint 170875-000 is a T-Mobile SIM card module engineered specifically for Cradlepoint ACS (Appliance Control System) devices. This accessory enables cellular connectivity through T-Mobile's network, delivering mobile broadband access for remote installations, field deployments, and scenarios where wired internet is unavailable or impractical. The 170875-000 is not a standalone device — it is a SIM-based extension that integrates exclusively with ACS-equipped hardware to provision wireless WAN connectivity.
Key Features
- T-Mobile Network Access: Activates cellular broadband over T-Mobile's LTE and 5G infrastructure, eliminating dependency on fixed-line ISP connections. Useful for temporary sites, warehouse expansions, and locations where fiber or cable is unavailable.
- ACS Device Exclusivity: Designed solely for Cradlepoint ACS appliances. Using this SIM in non-ACS hardware will not function — verify your appliance model before ordering to avoid installation failure.
- Field Deployment Ready: Enables rapid provisioning of remote sites without lengthy ISP onboarding or infrastructure setup. Particularly valuable for time-sensitive warehouse automation, temporary monitoring, or emergency response scenarios.
- Plug-and-Play Integration: Installs directly into the SIM slot on ACS devices. No external modem, router, or additional enclosure required. Reduces deployment complexity and footprint at the edge.
- Mobile Broadband Fallback: Provides redundant WAN connectivity when paired with primary ethernet connectivity on the ACS appliance, improving uptime and reducing outage risk for critical automation systems.
Integration & Compatibility
This SIM module works exclusively with the Cradlepoint ACS product family. Before installation, confirm that your appliance model supports the 170875-000 — incompatible ACS variants will not recognize or activate the SIM. T-Mobile network coverage is required at your deployment location; verify signal strength and data plan eligibility with T-Mobile before committing to this module. The SIM integrates with standard ACS management and provisioning workflows, allowing remote configuration through Cradlepoint's cloud management tools (if enabled on your ACS instance).
For integrators deploying multi-site warehouse automation or distributed surveillance systems, this SIM consolidates connectivity provisioning into a single, vendor-managed cellular module rather than managing separate carrier accounts per location. Organizations standardized on ACS appliances across facilities can deploy consistent, centralized WAN management.
Deployment Considerations
T-Mobile network coverage varies by geography — ensure adequate signal strength at your intended site before final purchase commitment. This accessory does not include a data plan; activation and recurring monthly charges are the customer's responsibility through T-Mobile. Cellular latency and throughput will vary depending on congestion, distance from tower, and network conditions; do not rely on this SIM alone for latency-critical or high-bandwidth applications without load testing first.
If your ACS appliance already includes dual ethernet ports or an integrated WAN failover feature, evaluate whether a second fixed-line ISP connection is more cost-effective than cellular service for your use case.
Frequently Asked Questions
Q: Is the Cradlepoint 170875-000 compatible with non-ACS Cradlepoint devices?
A: No. The 170875-000 is designed exclusively for ACS appliances and will not function in other Cradlepoint product lines such as routers or gateways. Verify your appliance model before purchasing.
Q: Does the SIM card include a data plan?
A: No. The 170875-000 is the SIM module only. You must activate a separate T-Mobile data plan and handle recurring charges independently. Contact T-Mobile for plan options and pricing.
Q: Can I use the 170875-000 as the primary WAN connection for my ACS appliance?
A: Yes, provided T-Mobile coverage is adequate at your site. However, for mission-critical deployments, a primary fixed-line connection with this SIM as backup failover is a more reliable architecture.
Q: What happens if T-Mobile coverage is weak at my deployment location?
A: Weak signal will result in reduced throughput, increased latency, and potential disconnections. Always conduct a pre-deployment coverage check with T-Mobile or use their coverage map tool before finalizing the installation.
Q: How do I activate the SIM in the ACS appliance?
A: Installation is physical insertion into the SIM slot on your ACS device. Configuration and activation are handled through your ACS management console and T-Mobile's provisioning portal. Refer to your ACS documentation for slot location and any required firmware settings.

The Cradlepoint 170875-000 is a straightforward accessory — a T-Mobile SIM carrier that plugs into ACS appliances to unlock cellular WAN connectivity. It's not a converter, modem, or multi-carrier solution; it's a single-network, ACS-only module. That narrow focus is both its strength and its constraint.
Technical Highlights:
- T-Mobile LTE/5G Network: Leverages T-Mobile infrastructure for mobile broadband where wired ISP is absent, unavailable, or cost-prohibitive — significant advantage for temporary deployments and multi-site field operations that cannot wait for 30–60-day ISP provisioning cycles.
- ACS Exclusivity: Works only with ACS appliances; attempting use in other Cradlepoint hardware will fail silently. This exclusivity is not a limitation — it reflects that ACS devices have a dedicated SIM slot and firmware support for this module that non-ACS variants lack.
- No Built-in Data Plan: You manage carrier activation and billing separately through T-Mobile. This puts plan choice and cost control in your hands but requires administrative overhead and advance planning to avoid activation delays at site deployment time.
Deployment Considerations:
- Always pre-verify T-Mobile signal strength and data plan eligibility at your site before finalizing purchase. Weak coverage or no service territory will render this SIM non-functional regardless of appliance configuration.
- Cellular latency (typically 30–100 ms on LTE, sometimes lower on 5G) is acceptable for appliance telemetry, remote control, and most warehouse automation workloads, but inadequate for real-time video streaming or VoIP without significant buffering or compression — test use case-specific throughput under your expected load before committing.
- Do not treat this as a primary WAN replacement in mission-critical deployments without redundancy. Pair it with a fixed-line connection at primary sites and reserve cellular for failover or temporary/emergency scenarios.
Deploy the 170875-000 when time-to-installation is more valuable than cost — sites requiring immediate remote connectivity, temporary warehouses, disaster recovery setups, or multi-location rollouts where centralized T-Mobile billing is preferable to managing individual ISP relationships. For permanent, cost-optimized deployments with heavy data use, evaluate fixed-line carriers first.
