In other words, it's not making any money. It's interesting that the Post Office is now referring to its mobile business as a "trial," which isn't how we remember it being communicated at launch less than a year ago. The service never grew beyond offering a single pay-as-you-go SIM, though, and only 263 of some 11,600 branches ended up stocking SIMs in-store.

If you happen to be among the undoubtedly small customer base, know that June 22nd will be the last day you can top up. And should you have grown particularly attached to your Post Office Mobile number, then make sure to request a PAC code soon to port it across to your next provider.
