This method only works on weekends, because it requires getting free 1GB data on recharges above N500, so when you recharge N2000(N1000 ×2), MTN gives you extra 2GB. If you have read the post on MTN Wow Weekend, you should know that your N2000 will still be intact. So you can use the N2000 to subscribe for MTN 2016 Data Deal which gives 7GB making it a total of 9GB.How To Get 11GB instead of 9GB for N2004 on MTN Techplus Data DealTo get 11GB instead of 9GB, it will cost N2,004 (two thousand and four naira) and also requires using the"Arsene Wenger Tactics to trigger Suarez release clause?" . Remember, MTN only gives bonus of 1GB on recharges above 500, recharging N500 might get you 100MB instead of1GB and they only have N500, N750...,recharge cards. The closest rechargecard after N500 is N750, so should you recharge 750 four times to get 1GB four times (4GB)? That will be too expensive You can use ATM for e-top up, this way you can recharge N501 four times (N501 × N4 = N2004),getting 1GB on each, making a total of 4GB. 4GB plus 7Gb equals 11GB.I'm positive better day are ahead in this data war, Enjoy your data.
