Honestly, I’m not feeling optimistic. I don't know why you guys are expecting so much from this merger. With the telecom market already saturated with high tariffs and lackluster service, I doubt this merger will bring the innovation or quality that you all are hoping for. Don't forget these Pakistani companies just look good on paper, they will always prioritize profits over providing quality service.
Wait, who's saying we're expecting so much from the merger?
TBH, two crap networks (this is subjective, apologies if I've offended you... NOT!) merging can either become stronger if they pool in their resources properly, or it'll remain status quo.
For example, Sprint/T-Mobile US: they now have the fastest data network for the average person (Verizon only scores higher in their mmwave areas, and the coverage for that is fickle). Sprint and T-Mo both had coverage holes (but then, this is the US where the landmass is massive), and Sprint had speed issues as well
In the UK, you had Orange and T-Mobile merging. Biggest and generally considered the most stable and reliable network. Not sure how they were before the merger, but I suppose there's a reason why Vodafone has remained in second place even after all these years (and Vodafone, apparently, isn't bad... it's just that EE is much better).
If Ufone/Telenor opt to use a vendor to properly manage their network, they could actually have a decent chance. Ufone's generally got decent coverage (but their voice can be choppy once it falls down to 2G). Telenor has a lot of widespread coverage, Ufone has dense coverage in pockets. Ignore the spectrum holdings for now, but if they pool in their resources, they could actually have a good network.
Do I trust them to do it? Hell naw! Like many Pakistani things, it'll be half-assed because people love shortcuts. This is why Jazz is still more consistent - they have fewer half-assing going on. Zong is just lazy when it comes to developing their network.
