What you need to send spam via SMS ?

I did a lot of research on this. I have worked for a few of my clients. I used a service whose SMS number is invisible and can only send SMS. If you PM me, I'll try to help.
 
Hey @Rakzs I now this thread is a bit old so... sorry for resurrect it. But I have 4 ejointech modems at hand and I'm a bit stuck trying to get them to work smoothly, so I'm looking for some advice.

Is there anything you can recommend to successfully use the modems? I was able to fill them with Ultra Mobile sims but they stopped working after sending a few hundred SMSs.

Anything from carrier recommendation to configuration wise in the modem will be highly appreciated it
 
Hey @German Rodriguez I'm curious regarding the throughput you are getting with this method. (Using Android phones) Would you mind sharing some numbers? like SMSs per day vs number of phones

I would advice to find someone with real experience in SIM termination to set it up. Each country/operator is a bit different and there are a lot of tricks to make things work and takes a lot of time to master. Otherwise, you are just wasting your time.
