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.

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