Just sharing....
I signed up for this 29.55 plan in October. With the Nokia ONT modem I noticed frequent internet disconnection. My wife who wfh most the times complained about this also. We have to restart the modem every now and then to get the internet back. We've been doing this workaround for weeks until we got fed up. I tried with 3-different routers but the issue remains. I contacted SH with the suspicion of faulty modem, and ask for replacement. The trooper arrived on the appointment date without a modem. Instead he replaced the fibre optic cable (yellow) with a 'thicker' size. He mentioned this fault is common with the Nokia modem. The connection has been stable after that. But SH charges $13 as transportation fee.
To those who are going for the installation, insist on the "thicker" fibre optic cable to avoid frustration.
Ps. You can also buy the thicker cable from lazada as a cheaper option then replace by yourself.
