When you say "veery bad singnal" (sp), are you saying you had no network coverage whatsoever? Or just that coverage was available, but data was slow/congested?
Was this during a special event at the ground? I can see a couple of permanent sites close-by, but depending how much peak-time usage was being generated, data congestion wouldn't be impossible I suspect.
Were voice calls & text messages functional throughout? Assuming you had coverage, of course.
