What kind of Internet phone can send short messages?

There are many VoIP phones, and I feel that ali tong VoIP phone is the best. It can not only be sent once, but also support mass sending. It can be used not only on computers, but also on mobile phones! Each message is only 0. 1 yuan, and the phone bill is recharged to send the phone bill. The more you recharge, the more you pay. Sometimes the tariff for each message is only a few cents, which is quite cost-effective ~
