No I know that, it's just that on AT&T, WCDMA/HSPA eclipses the range of edge. I live on the edge of cell for AT&T as well but I never see edge. It's always -120ish LTE, -110ish to -120ish WCDMA/HSPA or No Service. Is it just the way that T-Mobile has programmed their phones or does edge truly have a greater range than WCDMA/HSPA. Sometimes tmos edge gets up to 3 bars so I don't really know what to think.
