We have added a new action, Bounding Box Action (Japanese), to Soracom Flux.

The Bounding Box Action sets a border frame around the image at the specified URL. By setting this frame, you can explicitly indicate the target area within the image for subsequent actions that use it.

For example, you can use the Bounding Box Action to specify the target area on an image acquired via the RTSP Camera Image Action, and then instruct the AI Action to "detect objects within the red box," allowing you to perform AI analysis on a specific region within the image.

The Bounding Box Action is available on the Standard Plan and Enterprise Plan.

Soracom previously did not advertise an MTU (Maximum Transmission Unit) value to devices, so they relied on their implementation defaults (typically 1500 bytes). You can now configure the MTU per SIM group from the Soracom User Console so that the network advertises the value that best fits each deployment.

Why MTU control matters

MTU represents the largest IP packet that can traverse a link without being fragmented. When packets exceed the announced MTU, the cellular network must split them or drop them outright, which adds protocol headers, increases retransmission risk, and can prevent applications from communicating at all. Deployments that rely on VPN tunnels, private routes, or embedded devices with smaller buffers often had to work around the previous fixed MTU, leading to chronic fragmentation and lower throughput.

Benefits of customizing the MTU

By selecting an MTU that matches the rest of your network, you can keep packet sizes consistent end to end and avoid unnecessary fragmentation. Set a smaller value for VPN tunnels or other constrained links, while keeping the default for groups where the entire network between the device and its peers can accommodate larger packets.

Setting the appropriate MTU delivers the following benefits:

• Reduces unnecessary fragmentation and retransmissions, preventing throughput loss on cellular links.
• Prevents packet drops or application outages caused by MTU mismatches, reducing troubleshooting overhead.

Note: Some devices do not support MTU updates advertised by the network and will continue operating with their default value (typically 1500 bytes). Please confirm the device specifications beforehand.

For UI steps, API/CLI payload examples, and tips on verifying the right value (for example with ping), see IP Link MTU Configuration.

If you have any questions, please contact Soracom Support.

We are pleased to announce that the LTE Wi-Fi Router UD-LTA from I-O DATA DEVICE, INC. is now available in the Soracom IoT Store.

Key features

The LTE Wi-Fi Router UD-LTA is a Wi-Fi router with a built-in 4G (LTE) communication module and integrated antennas. It connects to the internet via 4G (LTE) networks, enabling smooth network setup in locations where installation of wired networking is difficult or for temporary deployments such as event venues. Use cases include remote monitoring of industrial equipment, payment devices, backup during outages, and many other applications.

Devices can connect via Wi-Fi or through the LAN port. A switchable LAN port can also function as a WAN port so you can alternate between wired and 4G (LTE) connections. Disconnecting the LAN cable triggers failover to the 4G (LTE) connection, helping deployments stay online during outages. The router also supports VPN protocols such as WireGuard. Pair it with Soracom Arc to keep using Soracom platform services even while the router is connected through a wired connection.

Availability and pricing

• Available countries / regions: Japan
• Price: ¥16,500 (tax included, shipping separate)
  • Includes a ¥1,000 Soracom platform coupon (valid for 6 months; applicable only to services with Japan Coverage)
