Hi Everyone. It’s very wired. I’ve been roaming overseas for 18 days. I could make calls, receive and send txt as well as on line surf. But this afternoon, I couldn’t send txt to anyone. I turned off and on my phone several times, but it didn’t help. Receiving txt, making calls, data roaming are fine, just can’t sending txt. I do hope there is an expert who can help me out. Thank you so much.
