The curent bad news is that Glo has suspended Glo special data offer N200 for 1.2GB. No more special data offer for Glo users.
If you dial *777# and you reply 1 and 1 to get the special data offer, it only presents you with Campus booster which is not a data plan you should ever go for. The Special data offer is no more in the list.
The only option you have is to either go for 9mobile 1GB for N200 or MTN 1GB for N200 which is SIM selective. As it stands now, OgaSim will be the best data plan to go for.
Let us know your thought and thought solution.
