What software can send text messages to mobile phones? Free/free

The biggest advantage of China Mobile's Fetion is that it can send short messages for free, and there is no service charge and no advertisement (better than the Netease bubble of that year), but the disadvantage is that you can send short messages to him only if the other party agrees to add you as a friend (reply to a short message). In addition, it must be from China Mobile, and this software is not easy to log in, and it is slow, a bit like msn in those days, but generally speaking, you can enjoy free short messages and input with the keyboard, which is not bad. You can install a java version on your mobile phone. Please refer to mender/rcmd/u/569848596/m/40 for details.
