Here is a screenshot. i understand that EDGE is the weakest signal of all. Let me tell you something. In India, 2G network (GPRS/EDGE) is the most common signal. 3G and HSPA or whatever that is, is a rarity. I am deliberately using 2G network because it is the only signal which will give me network connectivity in the first place. 3g is available in a few areas, but is generally not as strong and apart from that it is quite expensive, frankly. And the present screenshot is from when I HAVE data connectivity. The problem is that there are sometimes when i have "NO INTERNET CONNECTION" despite full signal bars. Deduce, from this what you will and tell me. I think it is time to switch carriers, though. Thank you.
