The “j=E” is used to establish the east longitude, whilst “j=W” is used for the west

An example of the longitudes is as follows: The first Lat.51º11'35.25''N,

In the formula the following must all have two digits: “aa,bb,cc,dd,kk,ll,mm,nn,qq,rr,ss”.
If the amount is less than ten a zero precedes the amount (e.g. 3 is “03”).
•
In the text message “fff,ppp” must be 3 digitals. If the amount is less than 100 a zero
precedes the amount (E.g. 11 is typed as 011).

The “I” in this formula must be in capital form.
So the SMS command should be
“123456I1,1,1,51113525N009125670E50241115N0110111.73E”
