    • Reliance EC150 and EC156, both models two variant firmwares are available in market. One is unlock-able through my firmware, which is provided in the article, and another one is not unlockable. That’s why some users tells that he unlocked successfully and some like you (unlucky person) says that it did not work. Unlocking of CDMA modems are only game of correct firmware. I have only one which I have posted in the article.
