Recently there has been a large increase of Mobile Virtual Network Operators (MVNO), which has created competition with Mobile Network Operators (MNO) and driven down costs for end users.
Some handset manufacturers have taken advantage by selling Open Market models, which are sold directly to end users and free from carrier customisation.
Open Market handsets must be tested with a wide variety of MVNO SIM cards to ensure a good end user experience.
End users expect all supported features to work reliably or they may choose to move to another MVNO provider and/or replace the Open Market handset with another model.
Open Market handsets are not SIM locked to the network provider, so end users can quickly change to another MVNO provider by simply inserting a different SIM card or putting a second SIM card in to dual SIM handset.
Open Market handset vendors make cheaper models, often with a lower specification so the handset probably will be replaced more quickly. However all supported features must work reliably to avoid products being returned as faulty and the overall user experience must be good to ensure customers are happy and retained.
The three core scenarios are:
Field testing is focused on checking the DUT works correctly with many different MVNO SIM cards. Test plans are carefully optimised to reduce duplication and increase test coverage, keeping costs down.
Our Live Network Testing, tailored to the customers requirements, comprises:
IoTAS will provide daily reports which include any test case failures observed during field testing. The final test report will be released at the end of the project, after being reviewed. All testing will be completed according IEC/ISO 17025.
