Ok so I have an LG Thrive and I text using apps over wifi. But recently I haven't been able to text my friends because they aren't receiving my messages. I have tried multiple devices and over 20 different apps but no cigar. My wifi signal is 100% up and idk what the problem is. I sent a couple texts then waited a week and they still didn't get them. Could it be something with my modem? Please help. Also, my friends have Verizon and tmobile so it can't be the provider. I used the apps such as Pinger Heywire Textnow etc.
