So @inspiron42,
Despite the fact that this feature is illegal and that O2 do not have the infrastructure to support it you feel giffgaff should offer it - how does that work?
Had the service about 25 years ago, it was a nightmare, stopped the service after a month

Why not divert calls from your fragile phone to your works phone when you need to?

@90elsa could you please substantiate your claim that it is illegal by quoting the relevant legislation.


I meant @ujo55 above.

Hi there, I'm afraid this is not legal in the UK so is not something offered by any network here.

Two sims with the same identity, ie cloned are illegal in the UK

@tazzy19  @_kara_ correct me if I'm wrong but what's not legal is two sims with the same IMSI number, i.e. cloned sims.

However, two sims with different IMSI numbers that are linked to the same mobile number aren't the same as cloned sims, are they?

There is a possible solution for you.


You'll need a second giffgaff sim:


  • put your main sim (the one with the phone number that everybody knows) in your best phone
  • on that main phone, set up divert on unreachable and divert on no reply, to the number of your second sim
  • put the second sim in the garden phone

The result will be that if incoming calls are unanswered on your best phone, they will go through to your garden phone. If you switch your main phone off, the diversion will take place immediately, but even if you forget the calls will divert after a short delay.


Normally, you pay for diverted calls as if you dialled the new destination yourself. But if you qualify for free giffgaff to giffgaff calls -- which you will if you have a recurring goodybag on the main phone, or if you remember to add some credit every 3 months, those calls will be free.


On the garden phone, you won't need a goodybag and a £10 PAYG credit could last many months or even years if you don't make many outgoing calls from it. But you do need to be sure to make at least one outgoing call or text every 6 months to avoid the sim deactivating.

I think projects like wifi calling would have to come well before that kind of solution could be put in place
