I just bump into YES booth at one of the phone shop at JJ Bukit Tinggi.
Yes they did said only can use YES service with YES devices.
and its not even available yet, their service only available on 22nd Nov 2010.
so I need to go that shop on Monday to register and use YES service.
BTW I have no more interest on getting YES when they said need to buy their phone/modem in order to use YES service.

so basically what their offer for voice call is voip right?

Huh what? Need to buy their phone? I thought only get their devices and surf online? I'm not going to drop my iDevice just because of YES providing cheaper rate.

Huh? Even iPhone 4 also not supported?

haih... tot that this maybe great since unifi will not reach my place for a while.... after all these and registered a 018 number then the big disappointment...

you mean "Yes"? but well, atleast they cover my area

if only unifi has aredy reach my place then i no need to choose any other bb provider.

i currently using izzi, will consider umobile

iPhone is a multimode device which support both GSM and 3G. It will fallback to GSM when there is no 3G.

HTC Evo 4G is a multimode device which support both CDMA and WiMAX. It will fallback to CDMA when t here is no WiMAX.

YES Buzz is a single mode device which only support WiMAX (if not mistaken). That's why you won't able to use voice when you are out of coverage.

There is not much information given on the YES Buzz, there is no technical specification as well.

There is also no mention whether YES signed any MVNO agreement with any local telco operator to switch to GSM/3G when the user moves out of YES coverage. That's what U Mobile did when they first startup.

As if that were not enough, Yes 4G has been publishing misleading ads on Google by targeting competitor brand names, whether on purpose or because they have incompetent AdWords managers. When I did a search for rival “p1″ on google.com.my, I saw the following ad (click here for a bigger screenshot):

The ad is obviously misleading because while it advertises “P1 Malaysia”, users are instead taken to the Yes 4G website. This is not only unethical but I’m almost certain that it infringes P1’s trademarks, which gives P1 good reasons to compel Google to take down the ads, and possibly even give them grounds for legal action.

YTL’s Yes 4G WiMAX service was finally launched, albeit to an embarrassing start, at 6pm yesterday. Proudly touting Yes as the “world’s first fully converged mobile Internet service”, “most affordable mobile Internet service with voice” and having “65% coverage”, its website has failed to load correctly even after more than 24 hours since the launch.

This has left many potential customers deeply disappointed after the long anticipation, judging from the negative responses on the blogosphere and Yes 4G’s own Facebook fan page.

Come on guys. Early days yet. I remember that P1 also had teething problems. Not a YTL fan boy. But to me, another service provider enables more competition which should be good for the end user.

The YES.my website is working fine.

Clarification regarding the RM30 MUR by the YES facebook admin:

"Hi everyone, to answer your questions on credit, credit will not expire. However, for the account to remain active, RM30 has to be loaded into the account each month. Any unused amount will be available for you to use the following month, s...o nothing is wasted As for our rate plan, Yes is mobile internet and from what we have surveyed, most mobile internet users do not use finish their monthly quotas. That means, most everyone is paying for something they eventually never use, that's why we believe the utility model with rebates on top of that will consistently save our customers money."

Not sure as I don't use prepaid, maybe similar to Digi/Maxis VOICE plan prepaid? But all other prepaid BROADBAND plan has expiry right?

1) Ask them to change their Terms of Use about MUR, then i can believe that "any unused credit will be available for you to use the following month" (see the attached Terms of Use.pdf) . If you complain about your credit been deducted, then they will say "It has been stated in our Terms of Use at our website, have you read it ??" . Do you want to say "But from the YES FB page, the YES FB Admin said not expired" ??? 
2) "RM30 has to be reloaded into the account each month" is like monthly commitment, if not, our account will be suspended, if want to re-activate, have to pay RM50 for activation fee
3) I dont think they survey for the heavy user, they only survey like mobile user
4) Their yes.my website still did not working.

@skthew u r right, if u dont utilize the svc over a period of 90 days, ur acct expires @iMleesh @soya_cincau

What does that say about their RM30 monthly commitment?
Aren't light users "not use finish their monthly quotas" of credit now instead of data?
If I use less than RM30 a month, at the end of one year I'm going to have a lot of unused credit.
What am supposed to do with it?

even u use less than RM30, they will still charge you RM30, so u wont have a lot of unused credit...

Read again.

That means you have to keep reloading RM30 even if you don't use one sen.
However since unused credit does not expire, your total credit will keep growing just like other celcos prepaid service.

So...
With other celcos, you need to top up RM30 for 30 days validity with RM30 credit.
With YES, you need to reload RM30 to keep your account active for the next month with RM30 credit.
Isn't that the same?

No commitment?
I think not.
