What's the difference between SMS, WeChat and email? Is texting too long? Too long to forward? Wechat has never been used. The above three method areas

SMS is the most convenient, because every mobile phone has SMS function, and there is no limit on the number of words, but it is charged according to the number of words, about 70 words.

E-mail has the most complete functions, such as adding any attachments, editing formats, etc. But it has the disadvantages of low popularity, not everyone has a mailbox and low time efficiency. Not everyone will often check new emails, and there are too few people who have email reminders.

Wechat is actually similar to qq, more widely used than email, but still not as good as SMS.
