AFAIK regardless of provider, lahat ng ISP sa pinas may maeexperience ng lag since PLDT ang main Lessee (owner ng lease) sa undersea cables, everyone else just buys a portion. Swerte mo kung mataas yung priority na binigay ng ISP or nagluwag sila ng bandwidth output to counter the lag. Using Smart LTE, still hitting same speed and latency as a few months ago.
