I haven't used it in a few weeks, so I don't know if it's working today.
Cost is 10 dinars for 45 hours of use (the hours expire within a month). Remember to turn the data of on your phone when you're not using it. Some smartphones send data in the background even if you aren't doing anything on the net so it will burn through your hours while you aren't doing anything.
To enable service send a text message to 8990 with either GPRS or 1 and you should be good to go.

This information is very accurate and you will get it working ,, Once you send to the said number a text message containing GPRS.
what will happen next,
1-You will receive the configuration for your mobile phone,, do not interfer ,, it will be automatically installed.. it just asks you to save it..
2- afetr the configuaration completes ,, a massage to cnfirm completion will pop up and say ( you can use the internet now) or something like that.
3- You will not be able to use internet unless you restart your phone,, so switch of and back ON ,, and here you got ,, surf the net.
