There are two suggestions, depending on the APN you use. You need YF client version 20101104-01 and above for this to work.
- APN wap.mtn.bj
Set tweaks to Benin MTN and protocol to "https", all else default values.
- APN internet.mtn.bj
Set tweaks to Benin MTN and protocol to "post", all else default values.
We have been told that these settings not only work in Benin but in all countries covered by the MTN One World program. You only need an MTN SIM card from Benin.
