  • Aircard 770s after unlock no network

    Dear Members and moderators,

    I would appreciate if you can help me to solve the problem i have, i just unlocked AT&T Netgear Aircard 770s with DC-Unlocker sw and it is showing in the device information unlocked.

    My problem is when i install Etisalat UAE sim card there is no signal at all, i have tried with many sim cards and i did factory reset to the MiFi with no luck

    Please advice

    Best Regards,
    Ayman

    Are those sim cards valid and working? If you have resetted device to factory defaults it might have became locked again. Make sure network type is not selected manually in options, but set to Automatic. Check if the APN settings are correct for sim card that you are trying to use device with.

        Yes, it may be band problem that bands which your modem uses are not used in your country.

            If device is unlocked successfully and problem is not in unlocking but in place you are using it then refund not possible.

              If such firmware exists for device then it should be located nowhere else but on manufacturer web page in their support section.

              The trick is to check what frequencies device supports, if it came from overseas then there is a high chance it does not support Europe's network frequencies.

                  It should br written in device specifications what bands it supports, what frequencies your European sim card runs should be available on carrier website or can give them a call for this info.

                    I found the specification about Aircard770S here:
                    http://www.speedguide.net/routers/ne...print=friendly

                    in particular:
                    HSPA: HSPA+ 850/1900 MHz w/ Type 3i Rx Diversity
                    LTE: LTE 700 MHz (AWS), FDD LTE Category 3,
                    here the band over the world
                    http://www.phonearena.com/news/Cheat...he-USA_id77933
                    Carrier 4G LTE Bands Frequencies
                    AT&T 2, 4, 5, 17 1900, 1700 abcde, 700 bc
                    Europe 3, 7, 20 1800, 2600, 800

                    Ok, the band are total different, but I ask:

                    If an american guy come in europe with AT&T, how he can do for use this device??
                    he can not use it...

                      You can't use this device in Europe unless some carrier provides services on frequencies that this device supports.
