Cannot send txts on DOro 6880 Message Center telphone number

[Tyhar]

Hello All

i was fiddling with some settings on my DORO 6880 and accidently cleared the last 2 numbers from the 

Messages->Settings->SMS->Message Center

(removed)

Since them I cannot send texts but I can make and receive calls plus receive texts. Im assuming all txts are sent to that uk message center and then sent on from there.

Sky have escalated but theres a 3 to 5 day wait. so If anyone knows that 10 digit number or could look it up on there uk Doro phone.  (Be careful dont delete any numbers like i did) I would be very thankful,

Moderator note: Removed phone number.
