how many mb does a text use
Text Message Bits and Bytes. SMS text messages use 7-bit characters and have a maximum length of 160 characters, making the maximum data size of each SMS 1120 bits, or 140 bytes. If an average mp3 song from iTunes is 4 MB, a text message is 0.0001335 MB. Almost nothing. So now weâre down to less than 4/10ths of a cent for 0.0001335 MB, or roughly $30 per MB. How does that compare with the current data plans offered by wireless providers? AT&T sells: A 200 MB monthly plan for $15 â 200x the data for half the price!
