I can forward pictures through my text messages, but when typing in a text to send, it does not send and I am not receiving text messages on my LG L15G, I do not receive a failed message warning either.
No doubt that's taking the fun out of your new phone. Few questions to start with? Did you just get this phone, and if so was your prev device an iPhone? Also did you port your number from one carrier to this new one by chance? Humour me if you have time. and send a text from your phone number all 11 digits(1-234-567-8910) and let me know what happens.
