I am doing SMS messaging in one of my apps, using the method of sending an email to all participants with their phone number and text message carrier address.
The problem is that this seems to work intermittently. Sometimes I will send a message and everyone will get it, sometimes only half of the folks will get it.
There doesn't seem to be a rhyme or reason.
This is a tour company. The text messages are going to people during their trip, providing up to the minute instructions and information. (Such as please meet back at the bus in the north parking lot at 10pm.)
These people will often only be going on 1 trip, so we don't want to require everyone to download an app - because they won't do it. However, we collect everyone's cell phone carrier and phone number prior to the trip, so I have all that info.
Currently, I am sending the message in batches of 80 or less, with all of the messages being blind copied. It may be that some servers are rejecting the mass text - but like I said, it works to everyone sometimes and not others - so I don't know what is going wrong.
Does anyone have a working SMS app that I can adapt to use with my system.
Willing to pay for the help.
We would be sending from to 20 to 500 text messages at a time, multiple times per day. Different numbers each time.
Any suggestions appreciated.
If you have an app that might work for me, respond here or by private message, please.
