What is the maximum length of unicode SMS?

The maximum SMS body length is actually  70 unicode-encoded characters (2 bytes each).

If you are seeing a maximum message length of only 70 characters this is an indication that you are requesting unicode encoding, For UTF encoded long messages, they are split into 67 character chunks (with 3 characters used for the segmentation info and to concatenate the individual messsages back together)
