Today got my oOkyo Sim, Inserted into phone @ around 3 or 4PM, activated @ 7PM, needed to install oOkyo Apps, and opened to get the unlimited data for certain apps.
Got some issues when from LTE dropped to H or H+ with "Network Change Detected needed to open the Apps again and refresh by sliding down and release, if still cannot, have to open airplane mode 10s and close it, and still cannot, need to restart the phone. There are also "unable to connect to the app properly if the line is not stable, hence you also cant get the unlimited data.
Sometimes the apps force close, and Error, we are unable to process your request at the moment due to technical difficulties.

Only times got stable on me is when im at dinner outside, with stable connection LTE, from 8pm to 9pm. Just back now, and again, error. Had to switch to wifi.

crap telco. oOkyo Apps just make vpn tunnel connections to oOkyo server. oOkyo should install this shit at oOkyo end not force user install vpn.

You can buy unlimited data pass to play your game without worry about data quota anymore. Can play 9GAG, Ultimate Ninja Blazing, Clash Royale, Dragon City & many more.

You can choose one of the apps & play the game online. Do note this is for only RM3/month for 1 app only. Standard Android games need 5-8GB data to play(if you are very active to play COC or 9GAG.

It's pointless to install vpn server to ookyo server side.

Somemore eat space for your mobile storage and RAM also.
I think it is compulsory to install the ookyo apps so that they can monitor what you play most in your phone.

Anyway, there is nothing attractive for this plan..
I though they will come out something new idea different compare from other MNVO or other telco.

Not compulsory. Install ookyo app

If don't install ookyo, is it will straight away utilize your 3GB data, am I right?

Yes you are correct

Got unlimited call for all network?

Since all data goes through their VPN, totally no privacy

No unlimited calls to all network, but can buy voice & SMS add-on for RM8 per month, 1,000 minutes and 1,000 SMS to all network.

Any updates on this ookyo ? kind of interested to know more.

Is it they can see everything at their end?

Can see everything, unless the data is encrypted.

No encrypted.

They can give government any info

Some data are encrypted right? Like whatsapp, the data is encrypted and only the sender and receiver have the keys to decrypt.

With or without VPN, ISP still can monitor your traffic if they wanted

2 weeks with ookyo -> the vpn use tons of battery

my ookyo its okay, not much to complaint about now, previous problems i got seldom occur d

why need VPN at the first place?
