On the HFC, I totally agree with you! The need to increase their fibre nodes (of which they've explicitly said they're doing, in earnest at that). I think that work is happening in conjunction with the FTTC work they're doing for areas with ADSL.
As for mobile... I see this calling rate push as an effort solely to attract net adds... they've made it clear that their focus for mobile going forward is data. They've been fortifying their HSPA & LTE layers islandwide to the point where the statistics coming back from benchmarks are astounding (especially for LTE). Many people are unaware OF how zippy their data network is... it's only when you show them and give an apples to apples comparison that they see the difference. Just yesterday I showed someone on Digicel a speedtest between them & FLOW's LTE network. Digicel, at full signal, topped off at 25 Mbit/s while FLOW did 31 Mbit/s.. while on a single bar of LTE. While they need a bit more site density (or a Band 5 refarm from GSM to LTE) to match Digicel on LTE retention, all they need to do is market the network as being the "Nation's Fastest" or what have you.... oh well
