Full disclosure, I've not had those issues before... Further, the combo plans have been nothing but tremendous to the point where now I have 20 GB of rollover data accrued since mid-May. What makes it even better for me is that coverage in Montego Bay & Kingston is supreme; once can rest assured that anything they need to do online can be done in seconds. Heck, my battery life is better than some of my friends on Digicel with iPhone X!
On the network side, for the moment, Digicel's Band 4 deployment(s) seem to be confined to Kingston & St. Andrew (heavily trafficked areas) and, their network quality since the ZTE upgrade in some areas according to some has taken a bad turn. Digicel has alot of work to do to catch up to FLOW. It's a pity I hadn't the screenshot which I took a speed test where both a Digicel & FLOW cell tower were located about 3 city blocks from each other (Fairview, Montego Bay) around 5 in the afternoon; Both were reporting full bars (iPhone 8 Plus on FLOW & iPhone X on Digicel). The iPhone X on Digicel hit 57 Mbit/s; excellent speed and would seem that their LTE layer was likely unloaded. On the FLOW iPhone 8 Plus, it hit 101 Mbit/s; near 2x the speed of Digicel - and carrier aggregation hadn't even been active on the iPhone on FLOW. Digicel needs to optimize, optimize, optimize! I gave FLOW flack for the substandard experience that I had last year this time (which was when they started the LTE deployments) and now, after months of work, it is impressive! Handovers happen without dropping... calls NEVER go to 2G and phones hand up to LTE after a call almost instantly! FLOW may be the smaller network in number but the tech behind it is the one to beat.
