How to send text messages (bulk text) from computer to mobile phone for free? !

It is generally not recommended to use mobile phones to send group text messages. The number of group text messages sent by mobile phones is limited. Forced group text messages may easily be blocked by the operator's mobile phone text messaging function. Adding recipients one by one is also troublesome. The price of bulk text messages sent by mobile phones is not as affordable as that of bulk text messages sent by bulk text messaging software. Beijing Suda Mobile Business Center SMS platform supports unified sending of PHS, China Mobile, China Unicom and numbers, which is convenient and fast, and the number of sending is not limited.
