I recently bought a GoPhone LG Prime and moved the SIM card from my old phone to the LG Prime. Everything worked, but messaging with other networks was spotty. My phone would send only some messages when it said it sent them all, and it would only receive some of the messages other people sent to me. I replaced this phone with another LG Prime and got the same result. Then I activated a new SIM card and the same thing happened! Has anyone experienced this and does anyone know how to fix it? Thank you so much!
