A Bit of Math

SMS max message size is 160 characters. One character equals one byte. There are 1024 x 1024 or 1,048,576 bytes in 1MB.

So there are 1,048,576 / 160 or 6553.6 SMS messages in 1MB of data.

NOTE: this assumes you use all the characters available in every message which none of us do. Some examples of really short messages show up on my phone frequently like “Ready?” “You home?” “Let’s go.” For illustration purposes and easier math, I’m assuming all 160 characters per message are used.

Calculating message traffic per MB these prepaid subscribers are paying the following rates.
