For reasons beyond our control, we have had to change the number used for Shared Inbound SMS in the Sandbox.

Users who have to date been using 447781480281 will now need to use 447800000319. This number is a direct replacement, and our systems have been reconfigured to route messages sent to this number to applications previously using 447781480281.

Please let us know if you have any problems.
