Tag SIMs to organise and filter your fleet

tag is a label you stick on a SIM card. SIMs can have any number of tags, and each tag can be applied to as many SIMs as you want. Tags don't change anything about how the SIM works. They're purely organisational, and they make every other dashboard feature (filtering, bulk actions, reporting) work better at scale.

This article covers how to create tags, apply them, filter by them, and delete them when they're no longer useful.

What to tag

There's no fixed taxonomy. Pick whatever cuts your fleet usefully. Common patterns:

  • Customer: acme-corpglobexinitech

  • Project or product: tracker-v2meter-rollout-2026

  • Location or region: germanymanchester-warehouseroute-66

  • Deployment phase: stagingproductionfield-test

  • Hardware: teltonika-rut240quectel-bg96

  • Internal owner: ops-team-1eng-fleet

Combining tags?You can combine tags freely. A SIM might be tagged acme-corp + tracker-v2 + germany + production, and show up in filters for any of those.

Apply a tag

From the SIM detail page

  1. Open the SIM in the dashboard

  2. Find the Tags box (usually top-right)

  3. Click the three-dot menu in the Tags box

  4. Pick an existing tag from the list, or Create new to make one on the fly

  5. Click Apply

During SIM registration

When you register a SIM (individually or in a batch), there's an optional tags step. Add the relevant tags then. It saves a round-trip later.

In bulk from the SIM list

  1. Open SIM cards

  2. Filter or search to narrow down, then select the SIMs you want to tag

  3. In the action bar, click Assign SIMs

  4. Pick existing tags or create new ones

  5. Apply

Bulk tagging is the fastest way to retro-fit a tagging scheme onto an existing fleet.

Filter and report by tag

Once your SIMs are tagged, you can use tags to scope what you see:

  1. Open the SIM overview page

  2. In the Filter panel, find the tags section

  3. Select one or more tags. The list updates to show only SIMs that match


Selecting two tags shows only SIMs that have both. To find SIMs with either tag, filter for each separately or use the API.

To export the filtered list:

  1. Run your filter

  2. Click Export in the action bar

  3. The export contains every SIM matching the filter, with ICCID, status, plan, usage, and tags

Bulk-act on a tag

Filtering by tag is the prelude to almost every bulk action. Common workflows:

  • Filter by tag → select all → Disable (for example, end-of-contract for a customer)

  • Filter by tag → select all → Change plan (for example, all eu-trucks move from USA to Europe coverage)

  • Filter by tag → select all → Send SMS (for example, command all firmware-v1.4 devices to reboot)

See SIM stateCoverage, and SMS for the individual bulk actions.

Delete a tag

From the SIM detail page

Remove the tag from a single SIM without affecting other SIMs that have the same tag:

  1. Open the SIM

  2. In the Tags box, click the X next to the tag

From the bulk Assign menu

Permanently delete a tag from your account:

  1. Select one or more SIMs in the SIM list

  2. Click Assign SIMs in the action bar. Your selection only determines where the menu opens from. Deleting a tag here removes it from every SIM in the account

  3. Hover over the tag you want to delete and click the bin icon next to it

  4. Confirm

Common questions

No practical limit. SIMs in large fleets routinely carry 5 to 10 tags.

Not directly. Workaround: create the new tag, apply it to everything that had the old one (filter + bulk assign), then delete the old tag.

Yes. Tag operations are available through the API. Useful for syncing tags with an external system of record (CRM, asset register, and so on).

Tags are private to your Simbase account. They don't appear on invoices or in any externally-visible output.

  • SIM state, bulk enable/disable scoped by tag

  • Coverage, bulk plan changes scoped by tag

  • SMS, bulk SMS scoped by tag

  • API, programmatic tag management
