This is for an older phone, so hopefully someone can help me. I have an unlocked LG KG320 that I've been using with T-Mobile's service. It has been working fine for about a year, until I travelled to Mexico. I used it once or twice in Mexico to speak to my family in the U.S., then turned it off and did not use it again until I returned to the U.S. I never switched out the SIM card, I was able to use T-Mobile service while roaming. Once back in US, the phone showed roaming, and then displayed the T-Mobile logo showing it connected to the network. However, I can't make any calls or send text messages, as it says network busy every time. No matter what I've tried, resetting it, manually selecting the network, it cannot make calls. Plese help! Thanks!
