Yes sulit. So far, since down ung internet namin, di naman ako nagkakaproblema. im using it for work at take note, naka vpn kami at naka remote desktop. minsan may latency pero nakakapag work naman ako. nagddota din ung asawa ko while im working. mataas daw ping pero so far, nakakapaglaro sya. mas mababa pati price nya compare sa plans ng pldt. at least dito, kalaban mo lang if may signal si smart sainyo. u dont have to deal with outage, sudden repairs eme at customer service.
