Hi, was doing some searching here and didn't have any confirmation from any previous post, so thought I'd help out any fellow OB that want to ditch the garbage Optus to something else. I've been with Optus for over 25 years and finally decided to pull the pin after my recent experience with the "free turbocharge" for the month of Dec. Not only did it not work, but the customer service I got to try resolve the issue was so bad, I decided I rather pay more and leave.
I'm on HFC and switched from Optus to Superloop a few days ago (Sunday). Took less than 15 mins. NBN modem turned off for a few mins, back on and I was up and running. Still using the Optus Sagemcom Modem, didn't need to change any settings or anything. Everything went really smoothly for me, so I guess I must be one of the lucky ones. I've read heaps of other reviews with bad experiences but decided to take a chance since it was cheapest for 1000/50 plan. Really happy with the new speed I'm getting now, but it's probably more than what I really need, so might downgrade after the 6 months discount is over.
So yeah for those wondering, YES you can use your current Optus Sagecom modem with Superloop, no configuration required.
21/12/23 UPDATE! So recently found out the Optus modem is either capped or can't upload faster than 20. Didn't notice it when I was on 50/20 with Optus. Now I'm on 1000/50, noticed the up was only around 20. Connected my PC directly to the NBN modem and speed was around 48 up. So changed the router and getting the correct speed. So maybe overall it's worth just changing modem as well and not use the shithouse Optus one.
Good job, I would change my isp the second I find a cheaper deal - true ozbargain style.
Also, about router compatibility, from my experience as well, most routers work fine with all the providers. Its just that your new isp will try to get u to purchase a new one through them to make a sale. They make a point that they can't help if you use a byo router, which is ok because they may not want to troubleshoot other routers than the ones they are offering. I guess it depends on nbn technology that you have, depending on that some routers might not work.
