Compare Hologram and Telnyx on features and dev experience as connectivity providers for your next IoT project.
At first glance, Hologram and Telnyx appear to be quite different. Telnyx operates in the CPaaS space, providing a suite of connectivity APIs that allow developers to incorporate voice, messaging, fax, webRTC, networking, video, and wireless capabilities into their applications. Hologram, in contrast, focuses solely on wireless connectivity.

<br>Let's further explore two distinguishing features that set Telnyx apart from Hologram: private LTE networks and over-the-air-based active steering.
The number one barrier to IoT adoption is security. 86% of enterprises using IoT say their IoT deployments have been delayed or constrained by security concerns, and 50% cite security as their biggest challenge to successful IoT implementation.
Private LTE networks are an effective solution to this problem, offering secure private connections that bypass the risks of the public internet. Telnyx, built on a private IP network, supports enterprise-grade security with private LTE networks, which are relatively easy to set up.
Organizations today expect wireless coverage across multiple carriers and automatic carrier switching. Both Hologram and Telnyx meet these needs with coverage across hundreds of networks globally and automatic carrier switching.
However, many providers use automatic carrier switching to cut their costs, often compromising network quality. Telnyx Wireless addresses this issue by prioritizing the highest quality network available and allowing users to configure their SIMs to prefer certain networks in real time through over-the-air updates.
Telnyx differentiates itself from Hologram by giving users access to the highest-quality available network and allowing them to configure SIMs to prefer specific networks in real-time via over-the-air updates.
Main takeaway: While Hologram offers many of the basic features expected of an IoT connectivity solution, Telnyx is the clear choice for those seeking enhanced security options or more network control.

What is a Hologram IoT SIM card? A Hologram IoT SIM is a cellular SIM or eSIM designed for connected devices, offering multi-carrier coverage across many countries for roaming resilience. It is built for remote provisioning, scalable management, and machine-to-machine traffic rather than consumer smartphones.
What is an IoT eSIM and how is it different from a consumer eSIM? An IoT eSIM uses the GSMA eUICC standard to let you remotely download and switch carrier profiles without swapping plastic SIMs. Unlike consumer eSIMs, IoT eSIMs emphasize long device lifecycles, rugged deployments, and fleet management at scale.
Are eSIM providers legitimate and secure for IoT deployments? Many providers are legitimate, but you should verify carrier agreements, GSMA-aligned provisioning, clear SLAs, and responsive customer support. Ask for details on data protection, profile management controls, and fallback behavior before committing.
What are the top alternatives to Hologram for IoT connectivity? Alternatives typically include global MVNOs focused on IoT, national MNO IoT divisions, and hybrid options that add satellite or private LTE for hard-to-reach areas. Compare network coverage, API reliability, contract terms, and billing transparency rather than brand name alone.
What should I look for in Hologram IoT eSIM reviews? Prioritize real-world feedback on coverage stability, latency under load, provisioning speed, API quality, and support responsiveness. If devices need to send photos or rich alerts, confirm that the stack supports MMS messaging and that media-size limits match your payloads.
How do coverage and roaming impact IoT device performance with eSIMs? Roaming quality shapes attach times, jitter, handovers, and battery life, especially for mobile assets or rural deployments. If alerts are sent via text, understanding SMS vs. MMS helps you choose the right channel and avoid oversized payloads that stall delivery.
What costs do reviewers commonly flag with IoT eSIM plans? Watch per-MB data rates, connection or platform fees, rounding increments, and extras like SMS, static IP, or VPN surcharges. For fleets that broadcast media-based alerts, factor the difference between group and broadcast MMS so your messaging budget stays predictable.
