I think this is a better move, Glo NG has upgraded their 1GB data plan of N1000 to 1.2GB. You can now get Glo 1200MB for N1,000.
» Load N1000 on your Glo Sim and dial *777#, then follow the prompt to choose your selection.
» Valid for 30 days
This should be a better alternative to iPhone/iPad, Symbian and Windows phone users. Also good for Android phone users who find it tough to use the available tweak or change their imei. The plan can be used any time, day and night and it works on any devices.
