Royal Mail, operator of Britain’s main postal service, has today announced that it has banned the transportation of Galaxy Note 7 smartphones through its network for safety reasons. The ban also applies to its Parcelforce UK and international courier service.

As you can imagine, this will make it particularly difficult for many Britons to return their recalled devices as they won’t be able to take advantage of the Note 7 Return Kits the South Korean company is rumored to distribute to customers in the near future.

It’s currently unclear how Samsung will respond, but we imagine that it’ll reach out to a privately-owned courier in the region to try and come to some sort of agreement about how it can transport the recalled units from owners to its home country.

This news comes almost a week after a report surfaced online claiming that Royal Mail was rejecting packages containing the Galaxy Note 7 following news circulating that a Southwest Airlines flight was evacuated on a runway when an alleged ‘safe’ unit burst into flames before takeoff.
