Edwin Haver, CIO, answers your frequently asked questions

How can I offer connectivity for consumer eSIM devices?

You will need to connect to a SM-DP+ server with live profiles available for hosted remote SIM provisioning on your network. We can quickly and easily enable operators to do this and start connecting the growing number of GSMA-compliant eSIM devices.

What do you offer? 

We provide a hosted remote SIM provisioning architecture with profile development and testing, an SM-DP+ cloud platform, and provisioning services as well as QR codes for subscriber activation.

What is the process?                                   

Going live is a relatively short process:

  • Test files: After agreements have been signed, we will need your input files – and if you are a new customer, your transport keys and profile data.
  • Test profile generation: We will generate output files, eSIM profiles and QR codes for you to test.
  • Proof of Concept testing: You will receive the test profiles for testing on your own network.
  • Final files: Following your user acceptance testing approval, we will require final input files.
  • Live profile generation: We will generate live eSIM profiles and their accompanying QR codes to support profile download and subscriber activation.
  • Go live: With your live profiles and supporting QR codes, subscribers are now able to connect their eSIM devices to your network.

How long will it take?

Going live using your existing subscriber registration process and a QR-code-based activation mechanism takes only between 2-4 weeks. This is the fastest route to market. We can also provide enhanced integration with the DP+ and self-care portals based on client requirements but would recommend this as a phase two implementation.

What are my hosting options?

We provide a GSMA SAS-SM certified cloud solution with hosting in London with alternative options soon to be in Amsterdam and Dubai.

Do I need a GSMA-approved hosted solution?

No, but a GSMA-certified solution is recommended to guarantee a fully interoperable and future-proof solution.

Do I need to work with an Apple-approved partner to connect Apple devices? 

To be able to provision Apple devices as per the standard, you do not need to work with an Apple-approved partner. However, if you would like to use the Entitlement Server, then this is a requirement which our solution provides.

Do I need an Entitlement Server? 

This is not required for iPhones but it is mandatory for provisioning the Apple Watch. Our solution provides the Entitlement Server.

Can I restrict users to just my network profile?

No, GSMA-compliant eSIMs enable multiple profiles to be provisioned.

Can subscribers use the same number across devices?

Yes, this works the same as it does currently using the existing number portability process.

What happens if the subscriber deletes the profile? 

Once the profile is deleted, it returns to the secure profile pool database. For the customer to reactivate the profile, they will need to contact the operator so the DP+ can be updated with the matching-ID and the existing QR code can be re-used or a new QR code assigned.

Can a subscriber use the same QR code to download or re-download a profile (e.g., to a second device)?

Whilst this is not part of the GSMA standard specification, it is possible and can be done based on customer requirements. Please note that a profile can only be active on one device at a time; therefore, it must be deactivated on previous devices first.

What devices work with your solution?

All consumer devices with GSMA-compliant eSIMs.

What is the cost?

We provide an extremely efficient low-cost, pay-as-you-go model with no setup costs, equipment or other CAPEX expenses required. Billing is done quarterly in arrears and based only on the number of profiles downloaded.

Can you provide a demo before I go ahead?

Yes, we can provide a demo with our devices or your own devices using our own network connectivity.

Is your solution secure?

Absolutely, we are both ISO 27001 and GSMA SAS-SM-certified and guarantee the highest level of information security.

What do you offer in terms of maintenance and support?

Workz offers various support packages. Our basic level of support provides complimentary remote technical support during regular working hours.

Why should I go with Workz?

We offer the fastest to market solution at the most competitive price with our Pay-As-You-Go payment plan, ensuring you only pay for what you use. The solution is highly reliable, interoperable, secure, and scalable with high capacity and redundancy.

Do you offer a remote SIM provisioning solution for M2M eSIMs?

Of course, we offer a specialised M2M solution to cater to the M2M architecture and its requirements. Again, we provide profile development and testing, a cloud-hosted SM-DP and SM-SR platform, and hosted remote SIM provisioning application.
