[Q] Samsung Galaxy S3 & ATT Dropped Calls

I received my new Samsung Galaxy S3 (GT-i9300) a couple of days ago and I'm on the AT&T Network here in the US. I have had my MicroSIM changed TWICE and still I'm getting dropped calls like crazy. I never had this problem with my SG2. Is anyone else with a S3 on the AT&T Network experiencing more than usual Dropped Calls and 3G Data loss (Web Pages not found, No Network Connection etc) - if so, did you fix the problem and HOW??? I have reset my APN (Cingular 410 / wap.cingular) to default so many times, it's ridiculous - any help is most appreciated


UPDATE:
I just installed the MicroSIM Card I bought on Amazon.com (SKU 73054) and removed the AT&T Furnished iPAD MicroSIM Card (SKU 72288) - the AT&T Tech admitted they gave me the wrong MicroSIM Card - TWICE. Proud to say that I am now getting 3 to 4 Signal Bars in My Basement where I was hardly getting 1 bar before. I highly recommend purchasing the 73054 Card from only ABE-123 on Amazon.com (all others are cut cards) to anyone that may be having Signal Issues. Thank You EVERYBODY for all your help and suggestions


This is where I bought it from: http://www.amazon.com/AT-T-Micro-SIM-Card/dp/B003YTSXYO

Mine is working perfectly. Are you sure you just don't have a phone with a defective radio??

Are you able to switch to 2G and see if you experience any dropped calls?

You know, I along with other users have noticed that the radio is not as strong as the... HTC One X...

But the HTC One X was made specifically for ATT wher ehte International version is not. I don't know why reception isn't as good but I do see my phone sometimes changing between 3G, H and H+. The signal is pretty weak.

If I switch to EDGE, I actually pick up an additional Signal Strength Bar - I sure hope I don't have a bad radio, I have no idea on how to check that...

Not to start an argument but having had the Lumia 900 and the One X, where I live, I found that the One X had a pretty poor radio when it came to reception.

The 1.85 update did help a bit, but the difference is noticeable when comparing it to the Lumia.

I don't know how to check if I have a bad radio - I'm about a quarter of a mile from a cell tower and I only have a couple of Signal Bars - but when I go to the AT&T Store, I get 4 bars but they probably have boosters in their store - I'm going back to AT&T tomorrow and plead my case, I have no idea what they will try next

Just a suggestion, but is it possible to reflash the image? Maybe a that would help?

Reflashing XXALE8 is tempting but I already rooted the phone and setup all my apps, I think I'll hold off on that till I get back from AT&T tomorrow but you make a very good point - i'm wondering if there is a later v4.0.4 firmware available for this UK Phone that might address the radio in this S3
