Why can't my Samsung note2 group send messages to four people at most? Any more will fail. Who can tell me how to set it up? Thank you. hum ...

Report LZ: I think it may be that you sent too many text messages per unit time and were blocked by the operator. Operators can't authenticate the content of your short messages (the workload is too heavy for anyone to check), so they limit the number of short messages sent per unit time, for example, only 1 can be sent.
