This works for both phone and pc.
This does not work on all MTN SIMS, Many older ones hace MTN SIM plus> MY Tools.....it won;t work on these.
Load #100 MTN card and press MENU on your phone the
Locate the MTN sim logo click and go to
MTN service > tools > data bundle > mobile internet > 10MB,
click to get the 10MB.
Note: Do not interrupt the processing and when its successfull don't go back, don't press the red key just follow the next steps by
Clicking tool > data bundle > FastLinks > 5GB,
Click it (5GB),
Once it start processing CUT it.
Note: Make sure u press the red key immediately u click on 5GB, don't allow them to send u a message,
Then exit it and go back and start browsing, your mb won't be deducted.
Now start browsing.
To know if your MB is being deducted or not just dial *559#,
Once you see 0 on the used on the popup that means ur MB is not deducted.
I may not be able to answer questions on this cos all my SIMs don't have the facility...MTN SIM plus won't let me go further. This is from a reliable friend and its working for him.
