I just got a Samsung Galaxy 2 a few days ago. I tried sending 3 texts yesterday and none of them went through. Each one took forever to even attempt delivery because i saw "sending" and had to wait for a few minutes only for me to see "Failed" each time! I had a simple flip phone before and never had any issues with sending nor receiving texts! Do I need to change some setting on my phone and how, or what do I do? I've done a google search and some people said to download updates but my phone says no updates available. Do I need to take the phone back to the service provider to fix it?
