Just want to verify it has both 850/1900 GSM frequency bands and is not euro-tri band. You phone is likely GSM only or perhaps a GAIT phone like I used to use w/ ATT before they shut off TDMA.
Some parts of Chicago are tough with some network changes happening at times. Indoor coverage is no longer good at certain locations, and other places now have a usable signal that formerly did not exist ;). There's also the possibility that the cell site (=tower) closest to you is being worked on/upgraded/etc.
Best method to test out the service is to borrow a friend's (newer) handset, that includes 3G frequency bands and insert your SIM to test the difference in person. Testing out two different handsets would be even better- sometimes ATT stores will let you do this.
Another place to check on coverage in your neck of the woods is Howardforums.com. Plenty of Chicago folks in the ATT forum to commiserate with there.
I use ATT for my cell phone service. I live in Chicago. I have had my Sony Ericsson phone for 8 or 9 years (yeah, I know...but I've taken very good care of it and it's very small and easy to use and I don't think there's anything wrong with it).
So...that is my question. Has cell phone service changed so much (new networks - 3G, 4G) that my phone is not working well because of that...OR, has my phone just somehow developed "bad reception" in its older age...OR, does my provider's coverage just suck where I am using my phone?
I wouldn't think that the antenna would "wear out" over time...
Is my phone not able to work as well with the new technology of the current networks? Is the signal different enough that my phone is having problems?
I don't want to buy a new phone just to have crappy ATT reception in the same places with the new phone.
Thanks very much for any help you all can offer.
