Just discovered a way you can use MTN to Browse absolutely free using you phone which will be there after interfaced with you system but note that it doesn't work for all phones it only works for sonyericsson and some nokia phones which must be less than the s60 series
and all chinese phones i believe you know what i mean,which have a browser.
this is all you have to do
got to your phone browse add this code to it if you can connect with with the website given below without charges the go surfing for free
Browser you must use
Opera browser i use 7.1
on your browser configure your proxy as 10.199.212.2 and port 8080
on your URL type wap.sonyericsson.com@www...........
.....means any website of your interest
for sonyericsson phones the code is not neccessary it is already embedded in it.
Good Luck, Happy Surfing
