Here are the Mobile Internet Settings for Ooredoo Users
For newer ooredoo connections specially phones like Samsung S8 and S9 the auto settings that get populated is not correct and you will get slow internet speeds.
To fix this you need to make sure that the APN settings only has APN set as OoredooData it should not have anything else in filled in, if there is a proxy remove it.
Settings for 3G / Internet:
Settings for MMS:
* for some devices there might not be a specified input area for port, for these devices use the gateway/proxy address as: 126.96.36.199:8080
