I do not take credit for “writing” the SMS Format Spotting Manual referenced in the initial post. I compiled all the information I could find, and tested it for fidelity with what was included in the document.
It now looks like the new number for Austria SMS_OE should be added to the list. Below is an idea of how the numbers could now be better presented (in alphabetical SMS order).
I do not know if those SpotSMS numbers should be included in the list or not. I am also not very familiar with properly presenting phone numbers for areas outside of North America.
If someone can compile a better phone number section for insertion into the document I would appreciate it. Present any improvement to Andy, and he can merge it into the proper place.
North America SMS_NA use 1-530-430-SOTA ( 1-530-430-7682 )
Austria SMS_OE use ( +436803110897 )
Europe SMS_UK use 07903 533046 ( +447903533046 )
Australia SMS_VK use 0447 568667 ( +61447568667 )
