Plus, it will be pretty helpful if you were to tell me how i can publish screenshots here (without attaching as thumbnails).
No idea how to do that
1. Create a folder called, say, "Public", in your PC's, "Pictures", file for instance.
2. Take screenshot and transfer it from your phone to this PC folder either via Wi-Fi or USB cable.
3. Go to, say,
Photobucket and sign up with them for free.
4. Follow their instructions on uploading an image from your PC. This will be from Pctures/Public that you have created.
5. Once uploaded to Photobucket, go to your Library and open the image and select, "IMG code", from Image Links box and paste it into your Android Forums reply.
Been using that new card (with a different carrier) for almost 5-6 hrs now. Signal hasnt dropped a single bar since.
OK, so you know you can get a better signal, (EDGE, 3G, HSDPA, H+?), with a different carrier in that particular location. However, assuming that you are at work, it does not follow that that same carrier will offer a comparable signal at, say, home. You must therefore find a carrier that offers the best signal in your main areas of use otherwise you will will be back to receiving slow, or no, connections in one or the other with all the attendant problems.
For instance, I can receive a brilliant signal from most of the UK carriers when I am in the larger towns and cities but only Vodafone covers most of my usage in and around the area where I live and work. This will involve you in asking friends in all locations what their signal is like and which carrier they are on. This will build up a picture of which carrier or carriers are best for your needs. As you have already discovered, going for a, "big", name without checking out the coverage first, is not the answer.
EDIT Do not bother with a screenshot now that I know it is a different carrier as this would tell me nothing essentially.
