how to unlock huawei e1550 HSDPA USB stick modem?

my uncle went to the philippines for 6 months for business trip...and bought mobile broadband... he gave it to me coz he said the 3 months subscription is over...i want to use it here in U.S. but the problem is its lock to its previous provider... i tried googling it but it only showed me websites that are not free...i went to http://www.chasingdaydreams.com/2010/07/unlocking-the-huawei-e1550/ i tried every method in there still no luck... is there another way to unlock this??? people said its easy but so far im having hard time unlocking it...

est instead of the free unlocks that doesn't work...you can pay and get a legit permanent unlock for your Huawei E1550.I suggest you can get it from Unlock-zone.com and remove the network lock easily.
