The Network Coverage control offers you the choice between 2 different network coverages.
This new option will give you the choice between 2 types of coverages : Premium & Standard
Premium network coverage is the current coverage, with the full list of operators available/
This is the option selected by default, and if you leave it as is, everything will continue with no service change.
But if you select “Standard network coverage”, your SIMs will now have access to the same number of covered countries, with a slightly reduced list of operators, enabling you to force/block operators in some destinations.
To find out which carriers are included in each network coverage type, please refer to the price list you received from your account manager.
