I don't know that for a fact, (I'm not on the network) but that's what media reports say.
On my way to work this morning, for obvious reasons, I passed in front of the Glo office in my neighbourhood (Gloworld, I think it's called). I usually don't use that route, but I did today (and obviously, I got to work late). Wow! I dint regret. The inside was packed to capacity and a canopy had been mounted outside with chairs arranged. There too was packed to capacity.
It's great the enthusiasm with which Ghanaians are receiving this new mobile phone company. I just hope we don't end up regretting it. It appears Glo already has more subscribers than Expresso (that's interested subscribers who have registered a phone number with Glo).
