porting using 1 PAC covering multiple mobile numbers

As a final overview for group sims and porting: if you have multiple sim numbers under a group plan the existing supplier MUST and can provide a pac code for each sim number if requested as this allows each number to port onto whichever new supplier the user of the number chooses.  Yes, the could provide a single pac code for all but that’s only if the account owner wants to transfer all sims to the same supplier.  In my case, with five sims, one of the users in their home location gets very low network coverage by Three, so instead they will be signing up to an alternative provider- hence why group plans must provide a pac code per number to allow the consumer the ability to choose the best supplier for each sim in the location it resides.
