it can work. you just need the right methods. 

Here, try this:
1. Connect your webe connection to your computer. (don't care how you do it, just make sure your PC is using the webe connection) 
2. Make sure your Chromecast and your PC are within the same LAN
3. Make sure you have installed the latest Chrome browser version and use the built-in Cast option
4. Use any media streaming service you want to cast it to your Chromecast. I've tested iFlix, Twitch and AnimeFTW.

Note that Youtube and Viki don't seem to work as it forces your Chromecast to connect to the streaming servers directly. I'm guessing that services with full fledged Android TV apps will behave similarly. Enjoy! 

Would Chromecast work?

The one that i mentioned before was phone to Chromecast.

About your method, need to set PC as hotspot, right?
What app you use to set PC as hotspot?

Hello bro,

Are you from Muar? I'm from Muar & thinking to get Webe Mobile. I have few question, 1) Can I keep my old number? 2) Does it support Nexus 6P? 3) How coverage here in Muar?

mi5 have band 5? You unlocked your band 5 manually is it?

not really muar town but muar area, to be exact bukit gambir.
1. yes, i port from celcom postpaid
2. not sure, not using 6p, need to ask all the sifu here.
3. Muar town is well covered with 4g, my area no 4g yet but got 3g, speed was acceptable and no problem.

the problem i am facing was tac and 2 step verification code. tac problem seem resolved after online chat with cs, 2 step verification code not solve yet.

Thank you bro for the quick respond. For 2nd question, I found it at Webe website, my phone is supported. How do you subscribe? Via online or walk-in? If want to walk-in, does it at TM point centre?

supported means no problem la. i works at KL, walk in to their center at Sunway pyramid last sunday. i think you can subscribe online they will post the simcard to you, don't think tmpoint can subscribe webe

no special tricks here. no hotspot or VPN is needed. 

it's just how the casting feature on Chrome browser works. You can cast local content from your PC to the Chromecast too. It's the same idea. Basically, casting through Chrome browser will use the internet connection from the PC. So, if you're using the webe connection on the PC, it's one-to-one.

Do note that certain services work differently like Youtube and Viki. 

Since TM surprise offer..

I think wanna wait for the email or SMS for the offer
Someone sharing that we can have rm10 discount for 12 months for webe subscription

supported means no problem la. i works at KL, walk in to their center at Sunway pyramid last sunday. i think you can subscribe online they will post the simcard to you, don't think tmpoint can subscribe webe

I'd rather terminate my streamyx account and use the money to subscribe to multiple webe mobile SIMs for now. Hopefully, webe continues to improve. I will definitely terminate mine in June when my contract ends.
