RUTX50 eSIM 5G industrial connectivity solution for remote sites, temporary power, harsh environments, thousands of devices rolling out with minimal engineering time — and everyone expects the network to “just work”.
Teltonika’s answer for 2025 and beyond is the RUTX50 eSIM variant.
This is the first flagship Teltonika 5G router that:
- runs 5G NR (SA/NSA)
- supports LTE Cat 20 fallback
- has dual physical SIM slots
- includes an embedded eSIM (eUICC) inside the chassis
This is the model with the embedded eSIM: Part code: RUTX50320100
(You must order this specific code if you need embedded eSIM. The standard RUTX50 does not include eSIM.)
What makes the RUTX50 eSIM different?
The standard RUTX50 is already one of the most capable industrial 5G routers around. The RUTX50 eSIM variant builds on it.
Core improvements:
| Feature | Standard RUTX50 | RUTX50 eSIM (RUTX50320100) |
|---|---|---|
| SIM Options | 2× physical SIM | 2× physical SIM + embedded eSIM |
| Operator change | Requires physical SIM swap | Done remotely — no site visit |
| Deployment difficulty | Depends on access | Cabinet stays closed; profiles pushed OTA |
| Roaming flexibility | Fixed to SIM profile | Multiple profiles stored and switched OTA |
For engineers rolling out IoT at scale, this changes the economics of remote deployment.
RUTX50 eSIM – Key Features
- 5G NR Sub-6GHz, SA + NSA
- LTE Cat 20 fallback, carrier aggregation
- Embedded eSIM (eUICC) — store multiple operator profiles
- Gigabit WAN + 4× Gigabit LAN
- Wi-Fi 5 (802.11ac), Access Point or Client mode
- OpenVPN, WireGuard, IPSec
- DIN-rail and cabinet friendly metal casing
- 1.8V/3V Mini-SIM (2FF) dual physical SIM slots
Rugged, fast, stable. Exactly what you’d expect from Teltonika’s X-series.
Why embedded eSIM matters in IoT
Most routers still rely on removable SIMs. Fine for offices, terrible for remote installations.
With eSIM on the RUTX50, engineers can:
- ship devices globally with no operator chosen yet
- activate connectivity after installation
- change provider without opening the enclosure
- push multi-network roaming profiles without downtime
No tray. No SIM removal. No driving to site because a carrier is congested.
Real-world deployments where RUTX50 eSIM is a no-brainer
Remote CCTV / ANPR
Cameras installed on harsh outdoor locations, often crane-lifted or mast-mounted.
When the operator changes — nobody wants to unbolt brackets to swap a SIM.
Industrial control cabinet
PLC / RTU / SCADA, sealed panel, signed off by the site.
Changing SIM shouldn’t require a permit and an engineer with PPE.
Temporary and pop-up networks
Events, temporary broadband, IoT proof-of-concepts.
Use one global eSIM, switch profile later depending on local coverage.
Renewable energy and infrastructure
Solar farms, EV charging networks, off-grid systems.
Once installed, you want zero human interaction.
VPN, security and remote access
Like every RUT device, the RUTX50 eSIM runs RutOS — Teltonika’s security-centred Linux distribution.
Included VPN options:
- OpenVPN
- WireGuard
- IPSec
- L2TP / GRE / SSTP tunnelling
You can also use Failover and Load Balancing across multiple SIMs.
eSIM + physical SIM = ideal multi-network resilience.
Using IoT eSIM and roaming SIMs with the RUTX50 eSIM
The embedded eSIM supports downloading carrier profiles over-the-air.
With eUICC, you can:
- store multiple operator profiles
- activate whichever profile you need
- remotely delete or replace profiles later
This is the difference between SIM-on-a-chip and eUICC:
| Term | Meaning |
|---|---|
| eSIM | The SIM hardware is embedded inside the router |
| eUICC | Allows profile download, swapping, and removing operators remotely |
The RUTX50 eSIM supports both:
embedded SIM + remote provisioning.
IoT SIM vs IoT eSIM (eUICC)
| Feature | IoT SIM (physical) | IoT eSIM / eUICC |
|---|---|---|
| Installed | Engineer inserts SIM | Embedded in router PCB |
| Change operator | Requires site visit | Done remotely |
| Best for | Single-site, static installs | Fleets, remote, roaming, global |
| Profiles | One | Multiple (store ~7+) |
IoT eSIM is the right choice when:
- sites are remote or secure access is difficult
- uptime matters and downtime is expensive
- operator changes are expected during life of project
Teltonika eSIM Bootstrap – how the router gets online before a SIM profile exists
When an RUTX50 eSIM boots for the first time, the eSIM may not yet have a full operator profile installed.
That’s where bootstrap comes in.
From Teltonika’s eSIM bootstrap logic:
A bootstrap profile is preloaded during manufacturing.
It gives limited connectivity so the router can fetch the real eSIM profile.
Bootstrap allows temporary access to:
- Mobile network authentication
- DNS / NTP
- Remote Management System / eSIM platform
Everything else is blocked.
The goal is simple: provide just enough data for the router to pull down the real eSIM profile.
Typical bootstrap cycle:
- RUTX50 eSIM powers on.
- Router connects using the bootstrap profile.
- Router contacts SM-DP+ / eSIM platform.
- Full eSIM operator profile is downloaded.
- Router switches to the operational profile.
- Bootstrap deactivates.
If a physical SIM is inserted, the router prioritises it.
If no SIM is inserted, eSIM bootstrap activates automatically.
This removes the classic chicken-and-egg problem:
“How does the router get online to download a SIM profile if it doesn’t have a SIM profile yet?”
Bootstrap solves that.
Why RUTX50 eSIM is the future of industrial 5G
It brings together:
- 5G Sub-6 SA performance
- Embedded eUICC for zero-touch SIM provisioning
- Dual SIM for resilience
- VPN + security stack suitable for IIoT
No more babysitting routers.
No more SIM swaps in windy car parks.
No more “we’ll have to come back next week when we get another SIM”.
The RUTX50 eSIM turns 5G into something deployable at scale.
