Yesterday i had a huge lag with getting responses back from people who had other carries...verizon, tmobile, sprint... so i called att and the first lady said she fixed it, which she didn't. I called back and the 2nd lady did something with my settings and said something like the different carrier texting was off. i never heard of this any truth in it? I never heard of these so called "settings" they can do. so anyway a little bit later after talkin to the 2nd lady it started working really fine and fast. u know like normal speed. so today same thing happens, but not as bad of a lag, but close enough, so i call the guy does some "settings" thing and tell me to turn off my phone and leave it off for 15 seconds then turn it on. i do, but it doesn't really fix it, so i say **** it im just gonna wait, so about 2 hours later it starts working again. its weird cause something like this happened maybe 2 weeks ago, but it wasn't as bad it was a very short lag and went away quickly. Anyway the funny thing is i know its not my phone because texts to att to att work fine for me. also i think the other carriers go my messages it was when they tried to reply to me that it took me like 45 min to get it. so back to my original question could it be they were doing things with the network at those times?
