I AV BEEN USING THIS FOR MORE THAN 2MONTHS NOW.
WHEN EVA I SUBSCRIBE TO 1.5GB FOR 1K, I WILL GET 3GB.

HOW DOES IT WORK.
1. TWEAK THIS IMEI 356602075735***

2. AFTER TWEAKING UR IMEI, KINDLY PUT UR PHONE IN AIRPLANE MOOD.

3. REMOVE IT AND WAIT FOR UR COMFIRMATION MESSAGE.

4. WHEN U GET A MESSAGE 4RM MTN, THEN SUBSCRIBE TO ANY DATA OF UR CHOICE.

5. WHEN U SUBSCRIBE THEN CHECK UR DATA WITH *131*4# YOU WILL SEE THAT UR DATA IS CALCULATED TIMES 2.

GOODLUCK.

NB: THE TRICK LAST FOR 6MONTHS.

ENJOY.
