I'm looking for a messaging app that not only uses data, but also my phone number instead of making a new one up. I have Hangouts and a few others, but they all have me use another number. And any that I've found that use my phone number use the carrier, same as the default messaging app. At my work we can only use wifi because data and phone can't get through all the concrete. I can usually get my messages fine, (only needs a second of service to get them) but my texts sometimes take an hour to go through if they do at all... But if I had data messaging, it wouldn't be a problem. I can use other apps, I know, but I wanted to see if anyone knew of any like I'm looking for.
