I am a sms addict, but still I don't send so many sms. I usualy send/get about 10 to 30 sms every day. Without adding mails and other tweets or facebook comments and messages.
hahaha.. by phone, mine gets sms about 120-150 messages one day... about 5 MMS per day and maybe getting fun with email or chat offlines about 15 messages. But, i like sending SMS to my friends and family could be until 250 sms to reply all of the messages, just enjoyable guys
I get about 5-10 and send about the same amount....the number went down because now I use data.messaging apps like whatsapp, liveprofile, etc
