Cons of Mobile marketing

However, there are also some drawbacks for using mobile marketing

1. The number of words in each text message is very limited. i.e. only 70 Chinese words. The message content has to be very direct and precise.

2. No visual can be shown in SMS. Only allows in MMS, which has a higher cost of delivery and only reachable to consumer who’s cell phone setting is activated for MMS receipt.

3. As sending SMS for commercial purpose is becoming more and more popular, “spam” SMS will violate the rate of opening an SMS. Consumers may feel annoying if they receive too many SMS
