  1. What is the simlock code for my E2550s 2…. When I go to it asks for simlock code to unlock modem. I have tried your advise and am now down to 3 attempts left to unlock this modem, I have tried to use the Huawei modem unlocker and it says the sim in the modem is locked but this sim works in my phone? Please try to help me before I lock this modem permantly

  2. hi friend ;
    my modem is already unlocked and now i cannot enter any sim lock code
    please what is the solution for it?

  3. I am in the USA and hope you can advise – At present I have an older iPhone, an expensive carrier, and wish to travel within the USA and abroad. I am considering a newer iPad Pro and using Skype in place of my cell phone service. I am wondering, as well, if something like what you are reviewing above can be used in place of my local broadband service for my home. Could a HUAWEI type of device replace my home broadband service, and, my cell phone service – which create two expensive monthly bills, and save me on my monthly expenses while providing me with wifi and (using Skype) decent phone service – just for the cost of a SIM card per month? Your advice would be sincerely appreciated.
