Connecting a construction site

Connect a construction site by listing the equipment that needs mobile data, separating camera traffic from lighter tasks, and testing at the actual installation positions. UK 4-network 5 GB is a starting allowance for a controlled site workload at £8.85 per active SIM per month. It is not an unlimited connection for every camera and person on site.

A welfare unit, temporary camera and small status logger can have very different requirements. Decide which devices need their own SIM and which will share a router before estimating data. The construction sector page covers this use case.

Plan one phase at a time

Write down what must be connected during the current phase and what will be added later. Include camera uploads, remote viewing, site administration and any staff access you intend to permit. Keep optional downloads separate so they do not quietly consume the allowance needed for essential equipment.

Check who is responsible for each device and its application. A working SIM does not configure the camera service or decide who may use a welfare unit's router. Agree those responsibilities before equipment arrives, particularly when several contractors share the site.

Use the following decision table as a starting worksheet. Replace each suggested check with the actual device settings and expected usage for your project.

Test after the site arrangement changes

UK 4-network roams across O2, Vodafone, Three and EE and uses whichever is strongest where the device is. This gives temporary kit more network options as it moves between locations. It still needs testing at each installation position.

Try router and camera positions before permanent mounting. Metal cabins, concrete structures and equipment enclosures are reasons to compare alternatives carefully. Test with doors and covers in their normal operating position. If the site layout changes, repeat the same data task rather than assuming the original result still describes the installation.

ThingSIM does not supply antennas or site surveys. Ask the hardware supplier or installer about an external antenna where the device supports one. Keep the tested cable and mounting arrangement in the record so a later relocation does not become an unexplained configuration change.

Decide how cameras will be reached

Every ThingSIM gets a private IP at no charge. Mobile data on that address cannot accept unsolicited inbound connections. If the camera's application initiates its own connection to a service, check that arrangement with the camera supplier and test it separately from direct inbound viewing.

A static public IP is £8 a month per SIM and is directly reachable from the internet. The customer must secure the device. Confirm access controls with whoever manages the camera or router before enabling direct access; a public address does not provide those controls for you.

Private networking is another option, with private APN, IPSec VPN and cloud interconnect available as extras. Reaching a 4G camera remotely helps distinguish the access requirement before you select an extra.

Size the allowance around real activity

For cameras, count the size and number of uploads and add expected viewing. For a shared router, include all permitted devices. Use a representative day and allow for setup and firmware downloads rather than multiplying a quiet hour by the whole month.

The listed plans are 50 MB, 250 MB, 1 GB and 5 GB. Choose a smaller allowance for a small logger if its measured use supports it. If a camera or shared router needs more than 5 GB, do not assume the recommended plan will cover it; review the workload and discuss the requirement through contact.

The portal shows usage. At the allowance limit the SIM pauses rather than charging overage, so someone on the project needs to watch the connection during busy periods. A SIM on a smaller plan can upgrade immediately, paying only the difference for the rest of the month. If it is already on 5 GB, the largest listed allowance, it needs to wait for reset. Review the workload before the next busy period.

Activate for the job, and decide between phases

Order up to 25 SIMs online by card, with fleet enquiries for larger quantities. Physical SIMs are posted to UK and EU addresses; compatible eSIM devices can use a QR code delivered minutes after ordering.

SIMs arrive inactive and billing starts when activated in the portal. A switched-on SIM is billed each month, including while paused, until it is ceased. For a short gap between phases, keeping SIMs switched on is usually simplest. For a long gap, cease the SIMs that are not needed and activate fresh £2.00 SIMs when the next phase starts. Activating, pausing and moving SIMs covers the handover, while setting up a 4G router covers configuration at the next location.

Common questions

Can 5 GB run all the site cameras?

Calculate each camera's uploads and viewing before deciding. A 5 GB plan is a fixed monthly allowance, not a promise to cover a whole site.

Do I need a public IP for remote viewing?

Unsolicited inbound connections need a static public IP or private networking. Check whether the camera instead uses an outbound connection to its own service.

Should I pause SIMs between building phases?

Pausing stops data but not the monthly charge. For a short gap, keep the SIM on; for a long one, cease it and activate a new £2.00 SIM for the next phase.
