Do you know what does the following means:
I know about the T but never seen an 0 in front of a T. If it is 0.T I can still understand. Could anyone please explain it to me.
Thanks in advance.
There isn't much difference. More correct would be 0 followed by as many dots as the minimum number of digits an external call can have, like three for emergency. Byt many people doesn't bother and just puts 0T, still calls works fine and that is what matters at the end.
Hope this helps, please rate pots if it does!
