[Sony Xperia S, Acro S, Ion] osiris010:
I'm not sure if this is in the correct section or not but I am having a very irritating and annoying issue with AT&T. I previously had a Moto Atrix 2 that ended up ****ting out on me due to faulty hardware (and then Moto wouldn't honor their warranty) so I bought the Sony Xperia ion since I have always liked Sony and their products. In between my Atrix dying and buying my ion I was using a very outdated (but amazing for its' time) Sony Ericsson w810i as a backup phone. The W810i kept giving me issues with my SIM card, it was always ever one of two error messages: The phone would make a noise and bug out for a minute before displaying "Insert SmartChip" as if I turned the phone on without a SIM installed. The other wouldn't make a noise at all, it would just display "Inactive SIM" where "AT&T" or "Emergency calls only" would normally be displayed on the phone's screen. Now, I assumed that this was because I bought the phone used, it's a six year old phone, and my Micro Sim to Regular SIM (homemade) adaptor might not have aligned the brass contacts up 100% every time.

However, now I have a brand new shiny Xperia ion. I love the phone and I love ICS. However, and I cannot remember if this issue happened with 2.3.7 or not too, but I will be texting or browsing the web and I will end up trying to send something, search or click on something when my phone alerts me that I have no network connection. And when I say no network connection, I mean absolutely nothing. No 4G/LTE/any other data, no phone bars. the corner of my phone displays the 5 grayed out bars with a red X next to it. The notification pull down menu that normally displays "AT&T" will display "No Service." Normally, everything returns slowly, in a matter of a few minutes. First I get my bars back, it'll display "Emergency Calls Only," then "AT&T," before finally I have full service and 4G again. But not LTE. Normally LTE does not come back and the only way I have found to reestablish an LTE connection is to restart the phone.

This is an enormous pain in the ass! For obvious reasons. Especially since I will be texting someone back and forth with no problem and then when I go to send a reply, boom, all of a sudden no service. Sometimes I will pull my phone out of my pocket and go to search something and there will be no service. This happens seemingly regardless to location. It happens on the street, at my school, in my apartment, in my room in my apartment - This issue happens anywhere where I would normally get 5 bars and LTE service. And on top of it all it will happen multiple times in a day, sometimes 3 or 4 times. Sometimes it will even happen within 10 minutes of it just happening!

I am having a hard time figuring out if this is an AT&T issue or a phone issue. Like I said with my Atrix 2 I had no issues with randomly losing network connection. With my W810i it would always have SIM card read issues (btw, I did end up getting a new SIM card when I bought my ion) and with the 810i it would happen close to 6 times a day, sometimes restarting the phone back to a "insert SmartChip" screen and having to do it all over again.

Im thinking that if the issues I am having are the same between the Sony Ericsson and the Sony that the ion just displays it differently since it is a smartphone and can function without needing a SIM card in it.

So my question is has anyone else on AT&T having a similar issue with the Xperia ion? Or has anyone had issues with any previously owned Sony or Sony Ericsson phones?
