Hi, I've been using IDmobile for a while now, and I'm a bit confused about getting a new plan when my pay as you go expires.
On the site there are regular plans, and special plans 'for existing customers' that seem to be much better value.
But the 'existing customer'plans try to send me a new SIM card if I purchase one.
Is it really most cost efficient to keep getting new SIM cards rather than using the same one? Can anyone help me understand what's going on here? Why can't I just buy these 'existing customer' plans for my current SIM?
Thanks,
