UK mobile number porting, without the stress.

In the UK, mobile number porting (MNP) has to work within 1 business day. That's not a target, it's a regulatory requirement.

This has been one of the biggest telecoms headaches for years. Achieving the 1-day switch means lining up several complex moving parts within a traditionally slow-moving industry with the end result being the user not losing access to their number for more than a few hours.

Our UK mobile platform takes on this painful technical headache so you don't have to.

When an end user moves their number, you need two answers: where the port stands, and when it's done. With most providers, getting either one often means raising the dreaded support ticket. Not with us.

Know the moment a number ports in or out.

Our new port-in and port-out notifications fire the moment a number port is completed successfully.

You can then use these notifications to trigger your 'Welcome' flows for new customers or as the trigger to cancel a subscription and send an offer to maybe bring the customer back. No guessing, no manual checks.

Everything you need to set them up is in our porting notification docs.

Mobile number porting dashboard.

We've also added a new porting status dashboard in the eSIM Go management portal, showing where every port stands without you having to ask us.

For every porting request, you can see:

• Its status, such as Open or Scheduled
• Whether it's a port in or a port out
• When it was submitted and when it's due to port
• The MSISDN (the mobile number) and ICCID (the eSIM's unique ID) it relates to
• The porting code and request ID

Filter by direction or status, or search by ICCID, to find the port you're after. This way, when an end user asks your support team what's happening with their number, the answer is already on screen. And you only need us in the rare event there's a hiccup.

Less chasing, cleaner books.

Put together, you can follow every port as it moves and know the moment a port completes. So, your team spends less time asking for updates, your marketing can be ultra-personalised, and your subscriptions stay in step with your end users.

Both are live now. Open the portal to see the dashboard, and set up the new port-in and port-out notifications from the docs.

Mobile number porting FAQs.

How long does mobile number porting take in the UK?

Ofcom regulations require a number port to work within 1 business day. With eSIM Go, partners can track each port in the porting status dashboard and get notified the moment it completes.

What's the difference between a port in and a port out?

A port in moves an end user's existing number from their previous network onto an eSIM on your service. A port out moves the number from your service to another network provider. In short: A port in happens when someone joins your network, a port out happens when someone leaves your network.

How do I know when a number has ported out of an eSIM Go eSIM?

eSIM Go sends a port-out notification the moment the port completes. You can use it to cancel the subscription on your side straight away.

Can I check a port's status without contacting eSIM Go?

Yes. The porting status dashboard in the eSIM Go management portal shows each port's status, direction, dates, MSISDN and ICCID.
